 FOREWORD

It is my pleasure, on behalf of the Council of Ministers, to present to you ECTEL’s Regional

Numbering Plan. The Plan is a part of the evolving regulatory landscape and forms an integral
part of the Telecommunications liberalization process. It represents an important contribution
towards the creation of a single telecommunications space in the OECS sub-region and should
help advance our vision for the transparent and equitable distribution of all available resources.

On May 4th 2000, the Commonwealth of Dominica, Grenada, St. Kitts/Nevis, Saint Lucia and St.
Vincent and the Grenadines signed the Treaty establishing the Eastern Caribbean
Telecommunications Authority. The Treaty’s preamble, sets out the thinking of the founders who
indicated that economic enhancement, the creation of an enabling environment for competition
and the provision of a universal service at affordable rates to consumers as the raison d’etre for
the establishment of ECTEL.

In order to achieve this, the Telecommunications Act 2000 was enacted to create a more robust
licensing regime. The Act also makes provision for the National Telecommunications Regulatory
Commissions to establish and manage a national plan for the allocation of numbers among
telecommunications providers in accordance with the regional plan established by ECTEL.

The Regional Plan is in keeping with the policy objectives of the Member States to create a single
telecommunications space and to maximize the use of resources through sharing and
collaboration. The Plan provides the rationale, purpose and objectives that will guide the
administration of numbers. The underlying principles are clear; these principles are in accordance
with existing international norms and reflect accepted processes and procedures to ensure
transparency, fairness and equity in the distribution of the limited number resource. Procedures
developed will, therefore, allow ECTEL and NTRCs to carry out their roles in a harmonized
manner and to address the needs of providers and consumers efficiently.

The reader will find that the Plan is a dynamic one and that several areas are still being developed
and will be open to ongoing public consultation. A few key issues are still being discussed, such
as the policies on the use of Home Number Identification Codes (HNICs), Fees for the use of
numbers, Number Portability and Electronic Numbering systems.

The benefits to be derived from the existence of the Numbering Plan are: taking ownership of a
national resource; ensuring equitable distribution and management of numbers and promoting a
vibrant competitive telecommunications environment. In fulfilling the legislative mandate in the
regulation of the numbers for the telecommunication sector, ECTEL must provide policies to
guide the management of the numbering resource in our Member States. It is important that we
ensure consistency in the allocation and assignment of the number and thereby avoid the
premature exhaustion of the resource. We must also eliminate all aberrations that currently exist
in the exploitation of these resources.

I am convinced that ECTEL is now well placed to continue the efficient management of this
national resource for the benefit of the people of our region. I therefore commend the Plan, as a
work in progress, conscious that there a few critical issues still to be further discussed and
articulated, as we set the framework for the development of the National Numbering Plans.

HON. GREGORY BOWEN

CHAIRMAN, COUNCIL OF MINISTERS

1. INTRODUCTION

1.1 The Background

This is the Regional Numbering Plan of the Eastern Caribbean
Telecommunications Authority (ECTEL). The Plan is a requirement of the
ECTEL Treaty that mandates ECTEL to “recommend a regional policy for
the conduct of telecommunications, in particular in relation to universal
service, interconnection, numbering and pricing, and to monitor its
implementation in the Contracting States.”

The Act requires that that the Commission shall manage a national plan for
the allocation of numbers among telecommunications providers in
accordance with the regional plan established by ECTEL.

The Commission shall, in managing the national plan for

the allocation of numbers among telecommunications
providers, pay due regard to the existing allocation of
numbers.

This Regional Plan contains:

• Rationale for a Regional Numbering Plan
• Method used in designing the plan
• the purpose and objectives
• Scope of the plan
• Principles used in the Plan
• International linkages
• Processes and procedures
• Issues for consideration;
• Glossary and
• Annexes

1.2 Rationale for Numbering Plan

Numbers are a limited resource. A Numbering Plan is required to ensure equitable
distribution and management of this resource, thereby promoting a vibrant competitive
telecommunications environment.

The Telecommunications Acts 1of the ECTEL Member States make

provision for the National Telecommunications Regulatory Commissions
to “ establish and manage a national plan for the allocation of numbers
among telecommunications providers in accordance with the regional plan established by
ECTEL.
The Commission shall, in managing the national plan for the allocation of numbers
among telecommunications providers, pay due regard to the existing allocation of
numbers. It is ECTEL’s responsibility to develop the Regional Plan.

1.3 Numbers in ECTEL
Governments in the OECS have had very limited intervention in the assignment of
numbers prior to the liberalization of the telecommunications sector. The advent of
competition and the desire to promote a competitive telecommunications environment
require that a fair and equitable distribution system be developed for the distribution of
numbers. This necessitates the development of national numbering plans and in keeping
with the approach of developing a single telecommunications space there is need for a
Regional Plan.

1.4 Availability of Numbers

Each of the five ECTEL States: Commonwealth of Dominica; Grenada;
St. Kitts and Nevis; Saint Lucia and St. Vincent and the Grenadines, has its own area
code assigned by the International Telecommunications Union (ITU) as follows:

Country Assigned Area

Code
Commonwealth of Dominica 767
Grenada 473
St. Kitts/Nevis 869
Saint Lucia 758
St. Vincent and the Grenadines 784

The current practice is to use the area code with a seven-digit telephone number
representing (theoretically), the availability of up to ten million numbers for each
Member State. There are some restrictions however on the numbers that can be used and
the actual quantity available for each Member State would be approximately eight million
numbers.

1.5 Issues in Numbering

There are various issues in the management of numbers and among the most critical
are:
• Central Office Code Administration;
• Uniform dialing Plan;
• Home Number Identification Codes (HNIC’s)
• Number Fees;
• Carrier Identification Codes; and
• Non-Geographic codes.
• ENUM;
• Number Portability

This Numbering Plan addresses directly all of the above but defers final resolution on the
issues of HNI Codes, Number Fees, Carrier Identification Codes, Non-geographic Codes,
Number Portability, and ENUM for subsequent consultations.

 2.0 PURPOSE AND OBJECTIVES

2.1 Purpose
The purpose of the Regional Numbering Plan is to:
 Fulfill the legislative mandate of the NTRC’s and ECTEL in the regulation of the
numbers in the telecommunication sector;
 Provide a framework for the development of National Numbering Plans;
 Provide the policies to guide the management of the numbering resource in the
ECTEL Member States;
 Allocate the national resource in a fair and transparent manner to facilitate the
development of the telecommunications sector in the ECTEL Member States;
 Ensure consistency in the allocation and assignment of the limited resource;
 Avoid the premature exhaustion of the resource; and
 Eliminate all aberrations that currently exist in the exploitation of the number
resource;

2.2 Why a Numbering Plan

The incumbent operator previously did the administration of numbers. It is however a normal
consequence of the liberalization process that this would be done by an independent
regulator. In a liberalized environment the numbering plan should be administered in order to
allow a fair and equitable competition among the different operators. Management of the
numbering system is now done by the NTRC’s in consultation with ECTEL.

The Numbering Plan for ECTEL must reflect the competitive telecommunication market for
the country. Hence a competition-driven Numbering Policy is being developed and will be
modified to accommodate new functions such as number portability, ENUM, non-geographic
codes and carrier selection.

2.3 Ownership of the Resource

Numbers are a limited resource of the Member States. In order to establish a fair and
transparent process for the distribution of this resource the States have first established
ownership through legislation and regulation. The Numbering Plan to is to administer this
resource.

7
3.0 SCOPE OF THE PLAN

3. 1 Scope
The ECTEL Member States belong to the North American Numbering Plan (NANP).
Each state has been assigned by the ITU its own area code or Number Plan Area (NPA),
which is not expected to be exhausted in the immediate future considering the present
population and its growth rate.
A word of caution however needs be inserted in that there is need to consider the growth
in demand for numbers from new services that use great quantities of numbers. This
growth in demand is countered by the trend of convergence where single numbers can
now be used for a number of different services. ENUM is one such case where
convergent services can be offered using single numbers.
The Plan contains:
1. The background and rationale for the Numbering Plan;
2. The Purpose and Objective of the Plan;
3. The Scope of the Plan including the assumptions, constraints and
context for the development of the Plan;
4. The Scope of the Plan
5. The General Principles to be applied in the management of the
numbering Resource;
6. The International Linkages and inter-relationships between the
various agencies in number administration;
7. The Processes and Procedures relevant to number resource
management;
8. The guidelines for the allocation, assignment and management of
the Central Office Codes (COC or NXX);
9. The Uniform dialing Plan;
10. The principles and procedures for the assignment and use of the
short codes;
11. All of the relevant forms and procedures for the management of
the Numbering Resource;
12. An identification of all issues requiring further consideration;
13. A Glossary;

3.2 Assumptions and Constraints

The following assumptions have been used in developing this plan:
- The population of the Member States will experience less than 5% growth over the
next ten to fifteen years;
- Every person will have some means of communication that requires numbers and will
impact on the numbers available in the nation specific NPA;
- The governments of the ECTEL Member States will provide the environment for
growth of the telecommunications sector.

A major constraint is that there are significant differences in the existing dialing Plans.

3.3 Existing Population and Growth Rate

The existing population and growth rate will provide indicators as to the exhaust of the
numbering resources in a particular NPA. In each NPA, there are approximately 8 million
numbers using the maximum ten digit number format.

8
The analysis of population growth in the OECS shows that the growth for all States in the
OECS is less than five percent for the periods 1975 – 2002 and 2002-2005 2. Some
countries, Grenada and St. Kitts, show negative growth. The conclusion is the Number
Plan Areas (NPA) or area codes will not be exhausted for a considerable length of time.
The local dialling plan will be using seven (7) digits while the overseas dialling plan for
countries within the North American Plan (NANP) will be ten (10) digits in keeping with
the recommendations of the NANP.

3.4 Technology in Use

The telecommunications services provided by the telephone companies in the ECTEL
Member States use digital technology. The cellular providers use both TDMA and GSM
technology.

3.5 Regulatory Requirements

The ECTEL Member States have decided that:
a) Telecommunications services must be accessible and affordable to the population;
b) Universal Service obligations are to be met by all licensed providers;
c) All providers of telecommunications services must meet quality of Service
Obligations.

4.0 PRINCIPLES

4.1 General Principles

The Numbering Plan has been developed in accordance with:
• The relevant rules of the International Telecommunication Union
Recommendations (ITU –R) regarding the integrity of numbering
resources;
• The instructions in the resolutions adopted by ITU Plenipotentiary
conferences relevant for the stability of the numbering plans,
especially the E.164 plan;
• Ensuring the sovereignty of the Member States with regard to
country code numbering plans and addresses;
• Maintaining the principles as enshrined in Recommendation
E.164 of the ITU Telecommunication Standardization Sector, in
whatever application they are used.

4.2 Special considerations

The Plan has been developed giving special consideration to:
• The principles concerning future numbering, naming, addressing and
identification plans to deal with emerging services or applications and
relevant number allocation procedures to meet telecommunication
needs.
• The Recommendations and guidelines for international
telecommunication numbering, naming, addressing and identification
resources being known, recognized and applied by all and used to
build and maintain confidence of all in the related services;
• Any necessary action to ensure that the sovereignty of Member States
with regard to country code numbering, naming, addressing and
identification plans is fully maintained, in accordance with ITU
Recommendation E.164 and other relevant Recommendations;

4.3 ITU-T Recommendation e.164

The ITU-T Recommendation E. 164 is the international public

telecommunication numbering plan.

This Recommendation provides the number structure and functionality for

the three categories of numbers used for international public
telecommunication – they are geographic areas, global services and
Networks. For each of the categories, it details the components of the
numbering structure and the digit analysis required to successfully route
the calls. Annex A of this recommendation provides additional information
on the structure and function of E.164 numbers. Annex B provides
information on network identification, service parameters,
calling/connected line identity, dialling procedures and addressing for
geographic-based ISDN calls. Specific E.164-based applications, which
differ in usage, are defined in separate Recommendations. The ECTEL
Numbering Plan will follow the general principles of ITU-T
Recommendation E. 164.

10
4.4 The guidelines for the allocation, assignment and management of
Central Office Codes (COC or NXX);

The Central Office Code (COC) or NXX refers to the second three digit number
in a ten digit telephone number e.g. in the ten digit number 758-453-xxxx, 453 is
the COC or NXX. The services which use COC’s are plain old telephone service
(POTS), Centrex, Direct Inward Dialling, wireless services, pagers, facsimile and
pay telephones. The ECTEL Member States are part of the North American
Numbering Plan (NANP) and by virtue of this the telephone numbering plans and
recommendations developed by the telephone industry committees in the USA are
applicable to them. The North American Standards will be adopted in the
development of the telecommunications infrastructure and the guidelines for
Central Office Code allocation will be in keeping with recommendations made for
the North American Numbering Plan.

The Guidelines includes:

• Implementation principles;
• Description of the Numbering database
• Who can apply for numbers
• Reserving numbers or codes;
• Assessment of applications;
• Response times;
• Conditions placed on allocations
• Withdrawal of reservations and allocations;
• Appeals procedure;
• Reporting, auditing and forecasting.

4.5 Principles for the operation of non-geographic codes in ECTEL

Member States;

4.5.1 800 and 900 numbers

The process for the application, award and terms of conditions for the use
of non-geographic codes will be subject to a separate consultation process
with the relevant stakeholders. Annex 19 outlines the critical aspect of the
guidelines for advertising to children in respect of 900 services.
These numbers and their use will receive special treatment and a detailed
section prepared on the application for numbers how they will be granted
and the terms and conditions for their use will be presented in this section.
Application for the use of any non-geographical Code will be made to the
NTRC indicating the purpose for which it will be used and demonstrating
why the service can best be provided through the use of non-geographic
codes. The NTRC will, in consultation with ECTEL, award the use of the
Code taking into account the principles of fairness and transparency
always ensuring that the numbers are utilized in a efficient and effective
manner.

11
4.5.2 Mirror Codes
The mirror codes were used in the Caribbean to facilitate access to the US
800 and 900 numbers. The incumbent has in place a paid 800 service in
several of the ECTEL Member States. “400’ Access codes are being used
to access overseas 800 numbers. They were however removed from
service as of April 1st 2004 and its inclusion as a section in the numbering
plan is of questionable value. Paid “800” numbers will be used to replace
the mirror codes.

12
5.0 INTERNATIONAL LINKAGES
5.1 Responsibilities
The National Telecommunications Regulatory Commissions (NTRC’s) will
administer the National Numbering Plan in consultation with ECTEL. The
National Plan will be developed from the Regional Plan. ECTEL will provide the
broad policy guidelines within the Regional Plan and provide advice on the
management of numbers.
In the exercise of their responsibility there will be the need for interaction and
consultation with several specialized bodies. ECTEL will establish and maintain
the various international linkages required for the implementation of the national
plans.

International Agencies

The organizations involved in the administration of numbers are:

5.2.1 NTRC- National Telecommunications Regulatory

Commissions
The NTRC’s will be responsible for completing the National Numbering
Plan in consultation with ECTEL and would be responsible for
implementation of the Plan.

5.2.2 ECTEL- Eastern Caribbean Telecommunications Authority

ECTEL will be responsible for the development of the Regional Plan and
consulting with the NTRC’s in the development and implementation of the
National Plan. ECTEL will coordinate the interaction with the
international agencies ensuring that the relevant obligations are met.

5.2.3 NANPA - The North American Numbering Plan

Administration is responsible for the coordination and administration of
the North American Numbering/Dialing Plans. These central
administration functions are exercised in an impartial manner toward all
industry segments while balancing the utilization of a limited resource.

5.2.4 NANC -. The North American Numbering Council is a Federal

Advisory Committee that was created to advise the Commission on
numbering issues and to make recommendations, that foster efficient and
impartial number administration. The NANC members are representatives
from telecommunications carriers, state regulators, and consumer
advocates.

5.2.5 INC - Industry Numbering Committee, a standing committee of

the Industry Carriers Compatibility Forum (ICCF) that provides an open
forum to address and resolve industry-wide issues associated with the
planning, administration, allocation, assignment and use of the numbering
resources and related dialling considerations for public
telecommunications networks within the North American Numbering Plan
(NANP).

13
 5.2.6 ATIS - Alliance for Telecommunications Industry
Solutions- a trade group open to membership of North American and
World Zone 1 Caribbean telecommunications carriers, resellers,
manufacturers, and providers of enhanced services. ATIS is heavily
involved in standards issues including interconnection and interoperability.

5.27 ITU- The International Telecommunication Union

(“ITU”) is a United Nations specialized agency that brings governments
and industry together to coordinate the establishment and operation of
global telecommunication networks and services; it is responsible for
standardization, coordination and development of international
telecommunications including radio-communications, as well as the
harmonization of national policies.

5.28 Telcordia - This is a multi facted entity that addresses issues

related to numbering. Telcordia has an Adminstrative Operating Company
Number (AOCN) /service facility that facilitates the rating and routing of
telephone calls for assignees of Central Office (CO) Codes (NPA-NXX)
and Thousands-Blocks (NPA-NXX-X). They maintain the necessary
rating and routing for the Buisness Routing and Rating Database System
(BIRRDS) and ensures that calls to a Service Provider (SP) are routed or
rated correctly and that proper information is kept up to date in the
BIRRDS.

5.3 International Relations

It is agreed that ECTEL will coordinate all activities and inter-
relationships with the international agencies as these relate to the
administration of numbers.
This is embodied in the Letter of Commitment attached as Annex # 21.

14
6.0 PROCESSES AND PROCEDURES

6.0 General Considerations

The process for the assignment of Numbers is as follows:
• The applicant submits CO code Assignment Form (Annex 2 & 3) to the
NTRC in the country of operation for certification.
• Upon verification by the NTRC that the request is valid, an
acknowledgement is sent to the applicant and the application forms are
forwarded to ECTEL.
• If the forms are found to be incomplete they are returned to the applicant
for amendments.
• ECTEL reviews the applications forwarded and acknowledges receipt of
the application on the NTRC’s Response/Confirmation Form (Annex 4)
within 5 calendar days of receipt of the application.
• The applicant is informed of the CO code assigned or its denial with
reasons within 10 calendar days of receipt of the application.
• The NTRC confirms to ECTEL that the codes recommended are
assigned.
• The information for the TRA/BRIDS databases is then submitted by
ECTEL to the appropriate party on Part 2 of the CO Code Assignment
Request Form for input.
• The NTRC is informed by the assignee that the CO code is in service
within six months of the actual in service date on the Confirmation of
Code In Service Form (Annex 5).
• The NTRC provides ECTEL an update on a monthly basis the
operational status all codes assigned in the Member States.
ECTEL will inform all corresponding parties (ITU, NANPA and Telcordia) of the new
central office codes issued. Annex 7 provides the time lines for the for processes outlined
above.

6.1 Central Office Code Administration

The Central Office Codes (COC’s) are the three digits immediately following the area
code and are administered by the local regulator, the NTRC. These numbers generally
identify the various operators and some operators use them to differentiate between
different services.

The Plan provides the purpose and scope of regulating the central office codes, the
assumptions and constraints and defines all relevant terms. The number codes assigned in
the ECTEL Member States are outlined in Annex 18.

6.1.1 Assumptions and Constraints

1. Central Office Code assignment guidelines have been developed
considering the current constraints and assumptions. The numbering
resources are considered a public resource, assigned in a transparent
and efficient manner and may be subject to an audit at any time.
2. The assumptions and constraints are outlined in Annex # 8.
3. The guidelines should provide the greatest latitude in the provision of
telecommunications services while effectively managing this finite
resource.
15
6.1.2 Assignment Principles and criteria for the assignment of COCs
The principles for the assignment of COCs are:
• CO codes (NXX’s) are assigned to licensed operators for use in the
facilities they operate.
• These codes are for use on the public switched telephone network and not
for use on private networks.
• CO codes (NXX’s) must be assigned in an effective and efficient manner,
as they are a finite resource. All applicants for initial central office codes must
provide proof of being a licensed operator in the geographic area for which
the central office code is being requested.
• All applicants for additional central office codes must provide proof of
being a licensed operator in the areas for which the CO codes are being
requested as well as additional information on the prescribed forms.
• The information submitted by all CO code (NXX) applicants must be
uniform and shall be treated as proprietary and duly secured by the NTRC.
• CO codes (NXX’s) shall be assigned in a fair and impartial manner to any
applicant that meets the criteria for assignment
• Any operator that is denied the assignment of one or more CO codes
(NXX’s) under these guidelines has the right to appeal that decision. The
appeals procedures will be in accordance with the Telecommunications
Alternative Dispute Regulations.
• Resource conservation measures should in no way prevent the assignment
of Central Office Codes.
These principles provide guidance on who are to be provided COCs, the conditions
and the processes for verification.

6.1.3 Responsibilities of the CO Code Administrator and Code holder

The responsibilities of the CO Code Administrator and Code Holder are outlined
in Annexes 9 & 10.

6.1.3. (i) Code Use

CO code (NXX) assignments are made subject to the conditions listed in Section
4 of this Regional Plan. Applications for additional CO Code Assignments are in
accordance with Annex 6. A code assigned to an authorized operator, either
directly by the CO Code Administrator or through the transfer from another
authorized operator, should be placed into service within 6 months after
notification of the assignment of the code by the CO Code Administrator.

Certification of the service status of a CO code is mandatory and forms part of the
conditions of these guidelines. The certification of the in service status of a code
must be done on Confirmation of Code In Service Form (Annex # 5).

Should the applicant or code holder no longer have need for the code, the code
should be returned to the CO Code Administrator for reassignment. If, after an
audit exercise or other means, it is determined that a code is not in service after 6
months as noted above, the CO Code Administrator will request the return of the
code.

6.1.3 (ii) Assignee/Code Holder Responsibility

16
 The authorized operator to which a CO code(s) (NXX) has been
assigned shall be responsible for the return of the CO Code(s) to
the CO Code Administrator. Annex 11 outlines the conditions for
the return of the codes. Codes will be returned under the following
conditions:
(a) It is no longer needed by the authorized operator for the
purpose for which it was originally assigned.
(b) The service for which it was assigned has been disconnected /
withdrawn
(c) The CO Code(s) was not activated within the time frame
specified in these guidelines
The assignee may in the case (c) above, apply to the CO Code
administrator for an extension date. This request must include the
reason for the delay in putting the CO code into service and a
commitment of a new activation date

6.1.3.(iii) NPA Planning Information

All CO code holders must supply, upon request of the CO Code
Administrator, a forecast of CO code requirements, which will be
used for projecting NPA exhaust and NPA planning relief. All such
data supplied shall be treated with confidentiality.

All information supplied by the CO code holders shall be

submitted to the NTRC on the form provided for such purpose and
must be submitted by the specified date. Any reluctance or undue
delay on the part of the CO code holder can result penalties in
keeping with the telecommunications law and regulations.

6.1.3 (iv) Responsibility for Code Relief Planning

CO code (NXX) planning relief is the responsibility of the CO
Code (NXX) Administrator the NTRC and wil do so in
consultation with ECTEL.
The responsibilities of the Authorized Operators are to:
1. Provide accurate data for the Central Office Code
Utilization survey by due date
2. Cooperate fully with the annual audit
3. Participate in the discussions with the CO code
Administrator on measures to be adopted to make efficient
and effective use of CO codes.

6.1.3 (v) Reclamation Procedures

The CO Code (NXX) Administrator, the NTRC, will communicate with any
authorized operator who has been identified as having CO codes in their
possession, which should have been returned to the Administrator for subsequent
re-assignment. The CO code(s) (NXX) which should be returned to the
Administrator must fall within the categories outlined in Annex # 11.

6.1.4 Criteria for the Transfer of Central Office Codes

17
 The procedure which follows outlines criteria which the CO Code Administrator
(The NTRC) uses in reviewing requests for transfer of a CO code (NXX) from
one authorized operator i.e. the current holder of the CO code to another
authorized operator (the applicant) making the transfer request. This criterion
applies to a situation where there is a single end user, the full NXX is assigned
and there has been agreement between the authorized operators for such transfer
pending approval of the government/regulatory agencies and the CO Code
Administrator.

All time frames applicable to the assignment of a new code apply in the case of a
transfer. The time frames needed to perform network and other rearrangements,
where necessary, associated with the transfer are not included in this guideline.

The applicant (i.e. the authorized operator who is the recipient of the CO code
(NXX)) must complete and submit a CO Code Request Form with a letter from
the current CO code holder certifying that there is agreement to transfer the CO
Code in question.

The CO Code Administrator, upon approval of the request, will inform ECTEL,
who will then liaise with TRA and BRIDS for the relevant changes to the
databases. Any costs associated with the updating of these databases will be borne
by the applicant in addition to any administrative costs.

6.1.5 Maintenance of these guidelines

6.1.5.(i) These guidelines may be reviewed and modified as required by a
committee established by the CO code (NXX) Administrator, the NTRC, and
including representatives of the regulatory authority in the ECTEL membership.
Consultation with the authorized operators will constitute part of the deliberations
of this committee. The committee will not be bound by recommendations made
by the authorized operators.

6.1.5.(ii) the authorized operator(s) may submit suggestions with

justifications, in writing, for modification to the current guidelines

6.1.5.(iii) The committee will decide on suggested changes by consensus.

Every effort will be made to accommodate the special situations peculiar to the
individual ECTEL member territory and authorized operator(s).

6.1.5 (iv) All regulatory authorities of the ECTEL members will be issued the
modified guidelines with the appropriate covering letter.

6.1.5.(v) All authorized operators will be advised by the CO Code (NXX)

Administrator that the CO Code (NXX) Assignment guidelines have been
modified and the effective date of the modified guidelines. They will be advised
as to where to obtain a copy for their use.

6.1.6 Appeals Process.

18
 All appeals in respect of the numbering process will be settled in accordance with
the Dispute Resolution Regulations.

6.1.7 Training
Training for the administrators in numbers management and administration will
be provided by ECTEL.

6.2 Uniform Dialing Plan

6.2.0 Overview
The Member States of the Eastern Caribbean Telecommunications Authority
belong to the North American Numbering Plan (NANP). Each State has been
assigned its own area code (NPA), which will not exhaust in the foreseeable
future considering the present population and its growth rate.

As reference the existing dialing Schemes, service codes, short codes and vertical
Service Codes in the ECTEL Member states are outlined in Annexes 12, 13, 14,
and 15. Short Codes in the USA (Annex 16) are presented as a typical example of
the use of Short Codes in a NANPA Administration and for possible application in
ECTEL Member States.

A Uniform Dialing Plan will be adopted for the Member States of ECTEL using
the following format:

1. Local calls (within a nation) – seven (7) digits consisting of

CO code (3 digits) + subscriber number (4 digits)

2. Calls outside the nation but within the North American Numbering Plan-
(NANP) – eleven (11) digits consisting of :

Toll indicator “1” + NPA (3 digits) + CO code (3 digits) + subscriber number

(4 digits)

3. Calls outside the North American Numbering Plan (NANP) up to 13 digits

consisting of 011 + country code + significant number

6.2.1 Recommendation for Dialling Plan

The following dialling Plan is recommended for the ECTEL Member States.

1. All local or home NPA calls be seven (7) digits

2. All overseas calls within the NANP be eleven (11) digits
3. All non-World Zone 1 calls remain as is, i.e. 011 prefix + country code + national
significant number

In other words:

Local calls – seven (7) digits CO code (NXX) + xxxx

19
Overseas calls within the NANP (WZ1)–ten (10) digits NPA + CO code (NXX) + xxxx

Non World Zone 1 calls – 011 prefix + country code + national significant number (up to
13 digits)

6.2.2 Recommendation for service codes, short codes, and vertical services codes

Eastern Caribbean Telecommunications Authority (ECTEL) will conduct specific

consultations on the use of the various codes.
The consultation would seek to:
a) Review the assignment and use of service codes, short codes and vertical service
codes with a view to standardizing the codes across the ECTEL Member States.
b) Formulate an implementation plan to bring the above mentioned codes in line with
the recommendations of the Industry Numbering Committee for nations belonging to
the North American Numbering Plan.

It is of benefit to do so because of the community of interest between the islands and to

enable citizens to access services without having to resort to a telephone directory for
common services. It will also assist visitors in using the telephone services in the islands.

Annex 17 outlines the current use of N11 Codes in the ECTEL Member States and it is
proposed that this usage will be modeled after the NANPA recommended usage as
outlined in Annex 16.
It must be emphasized that the assignment of CO codes, short codes, service codes and
vertical service codes must be done in such a manner so as to maximize the finite
numbering resources. The efficient utilization of the numbering resource is necessary as
new technologies and services become available and may be demanding numbers for
their application. It is therefore critical that there is strict adherence to the guidelines for
the assignment of CO codes and the management of the numbering resources in the
OECS. The implementation of a Uniform Dialling Plan will lay the foundation for the
successful management and assignment of the numbering resources in the member States
of the OECS.

7.0 ISSUES REQUIRING FURTHER CONSIDERATION

7.1 Use of HNIC’s in ECTEL Member States

The use of foreign Home Number Identification Codes (HNICs) and shared codes
in the ECTEL Member States is the subject of separate consultation.

The relevant issues will be identified and subject to consultation.

The Numbering Plans will then be modified to incorporate the results of the
consultation.

7.2 Numbering Fees

ECTEL will be conducting a consultation on the application of fees to the use of
Numbers. The proposed fee will be to ensure that all related costs for the
administration of numbers will be recovered.
These fees will be charged to the operator.
20
 The Numbering plan will then be modified to reflect the deliberations of the
consultation.

7.3 CARRIER IDENTIFICATION CODE (CIC)

The Country Identifier Codes (CIC) and its application have a number of key
issues to be considered. This issue will be subject to separate consultation. The
Plan will then be modified to incorporate the deliberations of the consultation.

7.4 SS7 NETWORKS CODES/ WIRELESS ID/ DATA NETWORK ID

Consultation will be held to develop a position on these issues. The Plan will then
be modified to incorporate the deliberations of the consultation.

7.5 Non Geographic codes

800 and 900 numbers

These codes are non-geographic codes and not directly under the administrative
control of ECTEL nor NTRC’s.
A number of administrative procedures are to be developed to cover the allocation
of these numbers and to ensure that those numbers in the control of existing
providers are assigned in a fair and transparent manner.
A number of guidelines to address advertising on these pay services are also being
completed and included in Annex # 19 for comment.
This will be an issue for additional consultation.

ENUM
ENUM is a protocol that is the result of work of the Internet Engineering Task
Force's (IETF's) Telephone Number Mapping working group. The charter of this
working group was to define a Domain Name System (DNS)-based architecture
and protocols for mapping a telephone number to a Uniform Resource Identifier
(URI), which can be used to contact a resource associated with that number. The
protocol itself is defined in the standards track document "E.164 number and
DNS" (RFC 2916) that provides facilities to resolve E.164 telephone numbers
into other resources or services on the Internet. ITU-T Recommendation E.164 is
the international public telecommunication telephony numbering plan. The syntax
of Uniform Resource Identifiers (URIs) is defined in RFC 2396 (1998). ENUM
makes extensive use of Naming Authority Pointer records defined in RFC 2915 in
order to identify available ways or services for contacting a specific node
identified through the E.164 number.

21
 Electronic numbering maps phone numbers to the Internet. This would have
significant implications for technological convergence and would enable a host of
new services. It is anticipated that all countries of Country Code 1 (CC1) would
have similar interest and issues including the issues of consumer protection,
privacy and security.

ECTEL member states will have to decide if they are opting into the ENUM and
given its wide reaching implication a separate policy document is being prepared
on ENUM to fashion how it will be treated in the final Plan.

Any new numbering plan must of necessity treat the issue of convergence and the
above issue of electronic numbering is only one of the issues that convergence
necessitates be treated as a matter of urgency.

The critical aspect of the implementation of ENUM is the resignation of the

country codes. A proposed draft for this process is attached as Annex # 20.
ECTEL present position is that this is a complex and involved process and
energies would be better utilized at this point in the development of the
Numbering Plan and to hold separate specialized consultations on this issue later.

7.7 NUMBER PORTABILITY

This is a complicated issue, which will require an analysis of the cost benefit
analysis of each type of number portability and will be the subject of further
analysis and consultation.

The consultation will address the various types of number portability, the
implications and its applicability to the ECTEL States.

The Plan will then be modified to incorporate the deliberations of the

consultation.

input to TRA (RDBS) and BRIDS. To the extent possible, code applicants should avoid
requesting an effective date that is an interval less than 66 calendar days from the
submission of this form. It should be noted that interconnection arrangements and
facilities need to be in place prior to activation of a code. Such arrangements are outside
the scope of these guidelines.

Requests for code assignment should not be made more than six months prior to the
requested effective date.

Per Section 4.1.3, the Pool NTRC will check this section if the NXX being requested will
be used for thousand block number pooling.

Applicant is not required to submit Part 2 of the code request form if it is doing its own
TRA (RDBS) and BRIDS entries, or if the applicant has arranged for a third party to
input the Part 2 forms data on its behalf.

WARNING! It is the code applicant’s responsibility to arrange input of Part 2

The Rules for Assignment of the Central Office codes are:

Initial Code(s)
CO codes (NXX’s) are assigned only to authorized operators, which must indicate
this in the manner prescribed on the forms provided for such purpose. (See Annex
2)

• The applicant must certify a need for numbers and indicate the area and
the service for which the numbers are required in the Public Switched Telephone
Network on the prescribed form. (See Annex 2)
• An applicant may request an NXX assignment for the establishment of
an initial Location Routing Number ( LRN ) per Point of Interconnection ( POI)
provided the applicant has no existing resources available for LRN assignment.

Additional code(s)
Assignment of additional code(s) must be made for an established point of
interconnection or switching entity by satisfying one of the criteria in the sections
below

• Additional CO code(s) (NXX’s) requests must have certification by the

authorized operator that the CO code(s) in service at a switching centre/POI , per
service provided at that switching centre/POI , will exhaust within twelve(12)
months . Documentation to support such certification must be supplied using
“Months to Exhaust Certification Worksheet” ( Annex 6) which has fields for the
following data:
o Telephone Numbers(TN’s) Available for assignment;
42
 o Growth history for last six(6)months;
o Projected demand for the next 12 months.

• Additional CO code(s) for other purposes must be accompanied by an explanation

of why current assigned resources to that entity cannot satisfy the requirement.

o CO code (NXX) sharing between operators , in which portions of the

NXX codes are assigned to multiple switching centres/POI’s may be utilized
where the operators mutually agree.
• This is particularly useful where the customer base is small
enough so that the operators will not need a full CO Code (NXX) of 10,000
numbers . In this scenario, unused numbers may be assigned
• to any operator on an as needed basis except where there
may be restrictions for wireless carriers .
o CO codes (NXX’s) shall be assigned on a first-come first-served basis .
Reserved codes will be held under the following conditions:

• CO code(s) shall be reserved if the authorized operator making the request can
justify that the reservation of the code is essential to accommodate technical or
planning constraints or pending regulatory approval of whatever kind provided
that documentation to support such request is furnished to the appropriate
regulatory body.

• No requests for a reserved code(s) will be entertained unless there is compliance

with criteria listed in sections 4.1.-4.1.2 for initial codes or sections 4.2-4.2.2 for
additional code(s) respectively.

• In any case , if a reserved code is not activated within 12 months , the code will
be released from its reserved status.

43
Annex # 8 Assumptions and Constraints in the Assignment of Central
Office Codes

The exploitation of the Numbering Resources in the ECTEL States will be

coordinated by ECTEL in accordance with an established Regional Numbering
Plan. The NTRC will assign the resource to operators for the purpose of routing
calls to subscriber terminals and may be included in the call record for the
purpose of rating calls.
The guidelines should provide the greatest latitude in the provision of
telecommunications services while effectively managing this finite resource.
The Numbering resources are considered a public resource and are not owned by the
assignees. Consequently, the resources cannot be sold , brokered , bartered or
leased by the assignee for a fee or other consideration . Transfer of code(s) due to
merger/acquisition is permitted.
If a resource is sold, brokered, bartered or leased for a fee, the resource is subject to
reclamation by the NTRC.
Numbering resources shall be assigned in such a manner that effective and efficient
use of the finite numbering resource is accomplished so that premature exhaust of
the numbers available does not occur.
Where regulatory approval is required , the applicant must be able to demonstrate that
regulatory authorization has been obtained for the area where the code is to be
utilized.
These assignment guidelines may not apply to an environment where number
portability exists. Another set of guidelines will be written to cover number
portability.
Administrative assignment of the CO code ( NXX ), a public resource by an entity
does not imply ownership of the resource by the entity performing the
administrative function , nor does it imply ownership by the entity to which it is
assigned.
Audits of the code applicant/holders may be performed to:
Determine compliance to uniformity in application of these guidelines
to all code requests received by the NTRC
Determine compliance with these guidelines by the code applicants
and Code Administrations determine whether the numbering
resources are being efficiently and effectively used by code
applicants and managed in an efficient and effective manner by the
NTRC
An applicant is not required to provide any additional explanation or justification of
items that he/she has certified. However, certification alone may not provide the
NTRC with sufficient information upon which to make a decision regarding code
assignment, and additional dialog and written documentation may be required.

44
Annex # 9 Responsibilities of the NTRC

1. Provide information to all authorized operators on procedures for applying for CO

codes with all the necessary forms and instructions on how to complete them.

2. Provide all authorized operators with any updates to the procedures and any
conservation procedures being invoked.

3. Receive and process applications for CO codes (NXX’s) for which the NTRC is
responsible.

4. The NTRC must reply to any request for a CO code(s) (NXX) within 5 calendar
days of receipt of the application form by completing the response portion of the
form in Annex 4.

5. Review the documentation and determine whether the code request satisfies the
procedures as outlined in these guidelines.

6. Where a request is denied, the applicant shall be informed as to the specific

reasons for such denial in writing . The applicant can appeal the NTRC’s decision
in accordance with the appeal procedure in these guidelines.

7. Select and assign an available CO code to the authorized operator and inform the
operator of such within 10 calendar days of receipt of the CO Code request form.

8. The CO Code (NXX) administrator, the NTRC, may , on behalf of the authorized
operator, request ECTEL to have the TRA and BRIDS databases updated for a fee
provided that the necessary forms (Part 2), have been duly completed and
submitted to the NTRC initiate reclamation of the CO code if it is not in service
within 6 months of its assignment.

45
Annex # 10 Responsibilities of the CO Code Applicants and Holders

(a) Applying for a CO Code

i. Authorized operators requesting initial and / or additional CO

codes (NXX) assignments shall submit their requests on the
appropriate Central Office Code (NXX) Assignment Request
( Annex 2) . A separate application form shall be made for each
CO code ( NXX) being requested . The applicant must complete all
the relevant fields on the Code Request form and have the form
signed by an authorized officer of the Company . All incomplete /
inaccurate code request forms will be returned to the authorized
operator for correction

ii. Requests for CO code assignments must be made at least two(2)

months prior to the in service date . This is necessary for the code
processing time (15 calendar days) and the 45 day activation of the
TRA and BRIDS databases, which provide the routing and rating
data for other carriers.

iii. Requests for additional CO code (NXX) assignments must be in

compliance with the requirement of Annexes 6 &7.

iv. The requestor shall certify on the CO code Request Form that the
necessary governmental /regulatory approvals have been obtained
to provide the service(s) for which the code is being requested .

(b) Information Required for Code Activation

In order to activate a CO code (NXX) the code holder or NTRC

(or if agreed or a third party), will ensure that Part 2 of the CO
code (NXX) Assignment Request Form has the relevant routing
information for entry into the TRA and BRIDS databases for
routing and rating respectively .

(c) Information Changes

The NTRC must be informed in the event of any changes to the
information supplied on the CO Code ( NXX) Request Form Part 1
which has been kept as record of the assignment by the NTRC .
These changes include but are not limited to the change of name of
holder e.g. in the event of merger or acquisition of the current code
holder or Tandem homing arrangement or other network changes

(d) Responsibilities of the Code Holder

It is the responsibility of the initial code holder or subsequent code

holder where the code has been obtained by merger or acquisition to
use the code in compliance with these guidelines. This includes
cooperating with and participating in the audit process necessary to
effectively assess code utilization. Any reluctance or undue delay on
46
the part of the CO code holder can result in fines or loss of licence to
operate in the designated area.

The code holder is responsible for the notification of TRA and

BRIDS of such changes, which affect their database or initiating the
updating of these databases through a third party.

47
Annex # 11 Categories for the return of Codes
The following categories of codes will be returned to the NTRC for reassignment:

 Assigned, but no longer in use by the authorized operator

 Assigned to a service which is no longer offered
 Assigned, but not activated within the time frame specified in these
guidelines
 Assigned, but not used in conformance with these guidelines
The relevant category will be determined as follows:
i. The NTRC will seek clarification, in writing, from the authorized
operator with regards to the status of the CO code(s) (NXX) in
question. The letter from the NTRC will be sent by registered mail
to the registered address of the authorized operator. The authorized
operator will respond within 21 working days of receipt of the
letter.

ii. If the NTRC decides that the explanation provided by the

authorized operator is satisfactory and is in conformance with
these guidelines, the CO code(s) (NXX) will remain assigned to
the authorized operator and the records of the NTRC amended to
reflect this.

iii. If the explanation is, in the opinion of the NTRC, unsatisfactory

and is not in conformance with these guidelines, the NTRC will
request in writing from the authorized operator reasons why the
assigned CO code(s) ( NXX) should not be returned.

iv. Should the authorized operator fail to respond within the 21

working days period from the date of receipt of the letter, the
NTRC will reclaim the CO code(s) and reissue them after an
appropriate aging period. TRA and BRIDS will be duly informed
of the NTRC’s action and be requested by the NTRC to remove the
CO code(s) ( NXX) from their databases.

v. The NTRC may decide to extend the activation date of a CO

code(s) ( NXX) , if requested by the assignee, provided that the
reason for non activation is not within the control of the assignee .

Such extension may be for a period of up to 90 days, whereupon

the status will be reviewed by the NTRC.

vi. It is the responsibility of the assignee to advise the NTRC of the

status of the CO code at the end of the 90 day period if the CO
code is still not activated. If the CO Code has been activated within
the 90 day period, then the assignee will provide certification of
the activation of the CO code(s) to the NTRC on the Confirmation
of Code In Service (Annex 5) .

ANNEX 16 The Use of Short Codes in the USA

In the USA, the service codes or N11 codes recognised as nationally assigned are as
follows:

211 Community Information and Referral service

311 Non Emergency Police and other Governmental services
511 Traffic and Transportation Information
711 Telecommunication Relay Service

All other N11 codes are assigned by the local authorities but there is an agreement that if
one of these codes need to be assigned nationally, the local assignment must be
withdrawn promptly. The traditional use of N11 codes in the USA is as follows:

211 Community Information and Referral service

311 Non Emergency Police and other Governmental services
411 Local Directory Assistance
511 Traffic and Transportation Information
611 Repair service
711 Telecommunication Relay Service
811 Business Office

Annex 19 Guidelines for advertising using Numbering Resources
Basic principles for the operation of the 1-900 numbers

These guidelines would apply for all advertising directed to children less than 16 years:

1. Advertisers should enquire as to the age of the caller.

2. Advertisers should always take into account the level of knowledge,
sophistication and maturity of the audience to which their message is primarily
directed. Younger children have a limited capacity for evaluating the credibility of
information they receive. They also may lack the ability to understand the nature
of the personal information they disclose on the Internet. Advertisers, therefore,
have a special responsibility to protect children from their own susceptibilities.
3. Realizing that children are imaginative and that make-believe play constitutes an
important part of the growing up process, advertisers should exercise care not to
exploit unfairly the imaginative quality of children. Unreasonable expectations of
product quality or performance should not be stimulated either directly or
indirectly by advertising.
4. Products and content which are inappropriate for children should not be
advertised or promoted directly to children.
5. Recognizing that advertising may play an important part in educating the child,
advertisers should communicate information in a truthful and accurate manner
and in language understandable to young children with full recognition that the
child may learn practices from advertising, which can affect his or her health and
well-being.
6. Advertisers are urged to capitalize on the potential of advertising to influence
behavior by developing advertising that, wherever possible, addresses itself to
positive and beneficial social behavior, such as friendship, kindness, honesty,
justice, generosity and respect for others.
7. Care should be taken to incorporate minority and other groups in advertisements
in order to present positive and pro-social roles and role models wherever
possible. Social stereotyping and appeals to prejudice should be avoided.
8. Although many influences affect a child's personal and social development, it
remains the prime responsibility of the parents to provide guidance for children.
Advertisers should contribute to this parent-child relationship in a constructive
manner.

Annex # 20 Draft Agreement for the Surrender of country codes

By issuing this acknowledgment and approval we understand that the Country is not
obligated to offer ENUM services. In addition, this approval does not require nor
obligate the Country to provide financial resources to __________ (CC1 ENUM NTRC)
or other participants offering ENUM services within Country Code 1. This simply allows
for the temporary delegation of the Country Code 1 in ENUM/e164.arpa allowing each
Country Code 1 country to establish ENUM/e164.arpa as it sees fit.
1As a member of Country Code 1, the Administration of ________________,
[hereinafter Country] hereby acknowledges and approves the temporary delegation of
Country Code 1 for the purposes of ENUM/e164.arpa to ___________ (CC1 ENUM
NTRC*). This temporary delegation is valid through XX/XX/XX, pending selection of the
long-term contracted provider and is renewable if the selection process is not complete
by the aforementioned date, with the following stipulation:

(1) The NPA(s) that have been allocated to serve the Country cannot be allocated
without the expressed written approval from the Country Administration. No
telephone numbers within exclusive jurisdiction of the Country will be
provisioned for ENUM without the express written approval from the
Country.

(2) Any delegation would be on the condition that _________ (ENUM NTRC)
would hold only the 'pointers' to Tier 2 databases and that the establishment
of these Tier 2 databases would be subject to the approval of the national
NTRC as designated by the Country or the Country, unless that NTRC waives
its right to such approval.

(3) Failure by ____________ to abide by this directive would negate this

approval.

(4) Any Country can terminate this agreement by providing at least one hundred
eighty (180) days written notice to the remaining CC1 Countries.

(5) As per the ITU-T Ad Interim guidelines, failure of any one Country within
CC1 to agree to the temporary delegation or any one Country within CC1
terminating this agreement will negate the temporary delegation of CC1. The
Guidelines specifically state: “For country codes within an integrated
numbering plan, the request corresponds to that portion of the code for which
the requesting Member State has administrative responsibilities. When a
request representing the entire integrated country code area is received, all
Member States within the integrated numbering plan must endorse the
request”.

This approval will be forwarded to ITU-TSB Director for purposes of validation.

_________ (CC1 ENUM NTRC) will then request the temporary delegation of Country
Code 1 for the purposes of ENUM from RIPE-NCC.

The term CC1 ENUM NTRC refers to the temporary Tier 1 entity and is only being used
for ease of reading. When a temporary Tier 1 provider is selected the term will be
removed.

Chairman NTRC:-

St. Vincent and the Grenadines

Dear Chairman

RE: REGIONAL NUMBERING PLAN

The Directorate is in the process of developing a Regional Numbering Plan that would
form the basis for the National Numbering Plans.

In order to facilitate the efficient administration of the number resource in the sub-region,
ECTEL proposes that the NTRC agrees that ECTEL acts as its agent in interacting with
external agencies in ensuring that all the numbers assigned are properly recorded and
accessible by all telecommunications providers worldwide.

To give effect to the foregoing, we specifically request the agreement of the NTRC on the
following matters:
1. That ECTEL will, in consultation with the NTRC, coordinate all activities
with international and regional bodies in respect of matters pertaining to
numbering specifically in reference to the Federal Communications
Commission (FCC), North American Numbering Plan Administration
(NANPA), The North America Numbering Council (NANC), Industry
Numbering Committee (INC) Alliance for Telecommunications Industry
Solutions (ATIS), Telcordia, the ITU and any other similar body.
2. That ECTEL will coordinate with Telcordia all activities in respect of the
entry of numbers assigned to operators in the LERG database to ensure
full operability.

Where applicable, ECTEL will seek representation in the bodies listed at item 1 above.

1. ECTEL will ensure payment of all associated fees in respect of membership or the
provision of related services by these extra-regional bodies;
2. ECTEL agrees to indemnify and hold harmless the NTRC from any reasonable
claims, damages, liability, attorneys’ fees and expenses arising solely as a
result of a failure by ECTEL to satisfy any obligation stated herein.
