Message Types
The following table lists all message types defined in this book.
For each message type, there is a short description, an indicator whether the message type requires
authentication (Y/N), the maximum message length on input (2,000 or 10,000 characters), whether the
use of the message requires registration with SWIFT for use in a message user group (Y) or not (N)
and whether value date ordering (VDO) can be requested for the message (Y/N). Value date ordering
criteria are described in the Standards MT General Information.

MT 105 Network Validated Rules
There are no network validated rules for this message type.
MT 105 Usage Rules
• When using this message you are requested to refer to the official Message Implementation Guide-
lines (MIGs) which contain full details on the format specifications and field specifications.
• The use and content of this message is governed by an established bilateral agreement between the
Sender and Receiver.
• The SWIFT character set 'x' ONLY must be used in fields 27, 20, 21 and 12.
• The EDIFACT syntax and level A character set (the 'y' character set on the SWIFT Network), as de-
fined in the EDIFACT syntax rules (ISO 9735), must be used in field 77F.
• It may not be possible to fit the entire EDIFACT message to be embedded in field 77F into one MT
105. When this is the case the EDIFACT message may be divided at any point within the text up to
the maximum field capacity for 77F of 1800 characters. An additional MT 105(s) should then be sent
until the entire EDIFACT message has been conveyed.
• When more than one message is required to convey the details of the EDIFACT message embed-
ded in field 77F the content of field 21 Related Reference of the MT 105 must be the same for all the
messages in the series.
4 Message Reference Guide - MT 105 EDIFACT Envelope
MT 105 EDIFACT Envelope
• It should be noted that, as is the case for all SWIFT messages, the last field in the message (77F)
must be followed by a 'CrLf-', to indicate 'End of Text'.
• It is recommended that EDIFACT messages be transported one at a time (that is, that two or more
messages are not put in a single MT 105).
MT 105 Field Specifications
1. Field 27: Sequence of Total
FORMAT
1!n/1!n (Message Number)(Sequence Number)
PRESENCE
Mandatory
DEFINITION
The sequence of total specifies the rank of this message in the series and the total number of mes-
sages in the series.
USAGE RULES
When only one MT 105 is necessary the content of field 27 will be '1/1'.
A maximum number of 9 messages may be sent in a series, in the instance below the content of field
27 in the last message of the series will be '9/9'.
EXAMPLES
In the second of three messages, field 27 will be '2/3'.
2. Field 20: Transaction Reference Number
FORMAT
16x
PRESENCE
Mandatory
DEFINITION
This field contains the Sender's unambiguous identification of the transaction.
NETWORK VALIDATED RULES
This field must not start or end with a slash '/' and must not contain two consecutive slashes '//' (Error
code(s): T26).
USAGE RULES
The detailed form and content of this field are at the discretion of the Sender.

3. Field 21: Related Reference
FORMAT
16x
PRESENCE
Mandatory
DEFINITION
This field contains the reference to the associated (enveloped) EDIFACT message.
NETWORK VALIDATED RULES
This field must not start or end with a slash '/' and must not contain two consecutive slashes '//' (Error
code(s): T26).
USAGE RULES
The content of this field should reflect, up to a maximum of 16, the significant characters of the Docu-
ment/Message Number (Data Element 1004) in the Beginning of the Message (BGM) segment of the
EDIFACT message embedded in field 77F. When more than one MT 105 is sent to convey the EDI-
FACT message, the content of field 21, must be the same for each MT 105 in the series.
This requirement is to facilitate the unambiguous re-association of the separate 'pages' of the transac-
tion, and also to provide a direct link to the EDIFACT message in case of further processing, for exam-
ple, cancellation.
4. Field 12: Sub-Message Type
FORMAT
3!n
PRESENCE
Mandatory
DEFINITION
This field contains the identification of the EDIFACT message contained within field 77F by its recog-
nized numeric code.

In addition to FINPAY, Customer payment, for which a three-digit, numeric code is to be allocated , the
following list of codes is currently available for use in field 12 of the MT 105:
381 REMADV Remittance Advice (Numeric code: 381).
NETWORK VALIDATED RULES
This field must contain a value in the range 100-999 (Error code(s): T18).

field.

quired to convey the contents of the EDIFACT message, the EDIFACT message may be divided at any
point up to the maximum field capacity of 1800 characters.
