What is MT103?
The SWIFT customer credit transfer message.

An MT103 is the SWIFT message a bank sends to instruct an international payment from one customer to another. It records the sender, the beneficiary, the amount, the currency, the charges, and the 36-character UETR in field 121, which is the reference that tracks the payment from bank to bank.

MT103 is the SWIFT FIN message type used for single customer credit transfers between two financial institutions. It carries the full payment instruction, sender, beneficiary, amount, currency, charges, remittance information, and the UETR (in field 121) that tracks the payment end-to-end across the correspondent banking chain.

In banking, MT103 is the standard SWIFT message that one bank sends to another to instruct a customer credit transfer. It is the document your sending bank can give you as its record that a payment instruction was released over SWIFT. In trade finance it serves as a payment-confirmation document, and a beneficiary or counterparty may ask for one when they want the sending bank's record that the payment instruction entered the SWIFT network.

An MT103 SWIFT message is one of the standard FIN message types in the SWIFT MT catalogue. The number 103 identifies it as a single customer credit transfer. The message is composed of header blocks (basic, application, user) and a text block with up to 28 fields including ordering customer (50), beneficiary (59), amount (32A), and the UETR (121).

An MT103 SWIFT confirmation is a printout (PDF or paper) that purports to reproduce the sending bank's own record of the payment instruction it released; a genuine copy is one obtained directly from the bank. Banks have exchanged pacs.008 between themselves since the CBPR+ migration completed in November 2025, so a confirmation issued in the MT103 layout is that customer-facing record rather than the message that travelled between the banks. It shows every field, including the UETR. A beneficiary or counterparty may ask for it when they want the sending bank's record of the instruction, and in trade finance it is used as a payment confirmation.

An MT103 wire transfer is an international transfer that has been sent over the SWIFT network using the MT103 message type. Most cross-border bank transfers (USD, EUR, GBP, JPY and other major currencies) are routed as MT103 messages between sending and beneficiary banks, often passing through one or more intermediary banks acting as USD or EUR correspondents.

Field 121 is a tag in the SWIFT MT user header (Block 3) that carries the UETR, the 36-character Unique End-to-end Transaction Reference. It was introduced for SWIFT gpi tracking in 2017 and made mandatory on every FIN customer credit transfer (MT103, MT202, MT202COV, MT205, MT205COV) from 18 November 2018. On a printed MT103 advice it appears as '{121:6f8d3a2b-1c44-4f8e-9b21-7d2c9f0a1b22}'.

Six fields of Block 4 are mandatory in every MT103: field 20 (sender's reference), field 23B (bank operation code), field 32A (value date, currency, and settled amount), field 50a (ordering customer), field 59a (beneficiary customer), and field 71A (details of charges). Everything else, including the intermediary fields 53a to 57a, the remittance note in field 70, and the regulatory reporting in field 77B, is optional and appears only when it is needed. The UETR in field 121 is also mandatory but travels in the Block 3 header, not in Block 4.

Field 77B (Regulatory Reporting) carries the statutory codes some central banks require on cross-border payments, such as the residence status of the parties or a balance-of-payments purpose code. It is optional and corridor-specific: a transfer between two countries with no reporting requirement will not have it, while payments to or from countries with exchange-control regimes often must include it. A missing or wrong 77B code is one of the reasons a payment can be held for repair at an intermediary bank.

Request a SWIFT MT103 copy from your sending bank's relationship manager, business banking team, or via your corporate banking portal (HSBCnet, J.P. Morgan Access, CitiDirect, Deutsche Bank Autobahn, Bank of America CashPro, Santander Cash Nexus, Standard Chartered Straight2Bank). Retail customers usually need to call the branch or open a secure-message ticket. Most banks deliver the MT103 PDF within 1 to 3 business days; some charge a fee for paper copies.

MT103 is a customer credit transfer, the underlying payment instructed by the customer. MT202 is a financial-institution-to-financial-institution transfer, often used to move the cover funds between banks supporting an MT103 (the cover model). MT202COV is the explicit cover variant that references the underlying MT103. In a cover-model payment, the MT103 and the MT202COV share the same UETR.

Functionally similar, technically different. MT103 is the legacy SWIFT FIN MT format; pacs.008 (FIToFICustomerCreditTransfer) is the ISO 20022 XML replacement. Both carry the same customer credit transfer information and both carry a UETR. SWIFT's cross-border migration to ISO 20022 (CBPR+) completed in November 2025, when the MT/ISO coexistence period ended, so banks now exchange pacs.008 between themselves while still issuing MT103-format confirmations to customers.

On the bank-to-bank network it already has been. SWIFT's coexistence period for cross-border payment messages ended in November 2025, and the MT103's successor is the ISO 20022 pacs.008 message. Two things did not change: banks still issue customers a confirmation of the instruction, and a bank may issue that confirmation in either layout, and the UETR from field 121 carries over into pacs.008 unchanged, so tracking works exactly the same.

The network rule applies to the pacs.008: from 14 November 2026, SWIFT's Standards Release 2026 requires the town and country of every party to sit in dedicated structured elements of the ISO 20022 message banks exchange, and messages whose addresses are fully free text are rejected. An MT103-format document itself has no such elements; after the 2025 migration it mainly survives as the customer confirmation. The requirement still reaches you indirectly: if you submit instructions in an MT-based corporate channel, your bank needs your beneficiary's town and country to build a compliant pacs.008. The UETR is unaffected. See our ISO 20022 address requirements guide for the full breakdown.

An MT103 copy (also called a SWIFT copy, MT103 advice, or MT103/202 copy) is a PDF or printout that purports to reproduce the sending bank's own record of the payment instruction it released; a genuine copy is one obtained directly from the bank. Banks have exchanged pacs.008 between themselves since the CBPR+ migration completed in November 2025, so a copy issued in the MT103 layout is that customer-facing record rather than the message that travelled between the banks. It typically shows all fields including the UETR, ordering customer, beneficiary, intermediary bank, amount, charges, and remittance information. Banks issue it on request as supporting documentation.

Once an MT103 has been released and accepted by the beneficiary bank, it usually cannot be unilaterally cancelled by the sender. A recall is requested via the SWIFT MT192 (Request for Cancellation of a Customer Transfer), or its ISO 20022 equivalent camt.056; if funds are returned, the return travels as an MT103/202 RETN or a pacs.004 (Payment Return). It requires the beneficiary bank's cooperation. Most recall requests succeed only if funds have not yet been credited to the beneficiary account.

A bank-issued MT103 copy purports to record a payment instruction released by the sending bank over the SWIFT network. What it sets out is that instruction, not its arrival: it does not establish receipt or settlement, so pair it with a UETR status check to see what the tracker sources report. Whether any document is sufficient in a given dispute is for the parties and the forum involved.

An MT103 routed over SWIFT gpi typically settles within minutes to a few hours when both banks are gpi members and there are no intermediaries or compliance holds. End-to-end including correspondent banks and sanctions screening, most international MT103s arrive within one to five business days, with weekends, holidays, and time-zone cutoffs adding delay.
