What is MT103?
The SWIFT customer credit transfer message.
MT103 is the technical name for the message your bank sends over the SWIFT network when you make an international wire transfer. It carries everything about the payment — who's sending, who's receiving, how much, in which currency, who pays the fees — plus the UETR tracking number that lets you follow the wire from your bank to the beneficiary's bank.

Why an MT103 can still go quiet
An MT103 is an instruction, not a settlement. Once your bank dispatches it, the wire often passes through one or more go-between banks (the industry calls them correspondent banks) before it reaches the beneficiary's bank. Each go-between has its own compliance checks, cut-off times, and operational queue — and any of them can hold the wire for hours or days.
Your bank's online portal usually only shows you what your bank did with the wire. The handoffs in between — where most delays actually happen — live in SWIFT's own tracking system, tied to the UETR.
This is why an MT103 copy proves the wire was sent — but doesn't tell you what happened to it after it left your bank's hands. The routing instructions are all there, but the live tracker events aren't.
That's what the UETR (the tracking number inside the MT103) is for. Paste the UETR into uetr.ai and we surface the available timeline from SWIFT's tracking network — so you know which bank in the chain is holding things up.
How an MT103 actually works
The 5 sections of the message, the fields that matter, a real sample annotated, and the upcoming switch to a newer format.
01/ The 5 sections of an MT103
An MT103 message is divided into 5 sections that SWIFT calls "blocks". Block 1 says who's sending the message. Block 2 says what kind of message it is (in this case "103" — a customer wire) and who it's going to. Block 3 is where the UETR tracking number lives. Block 4 is the payment instruction itself — sender, beneficiary, amount. Block 5 is a tail with a checksum the SWIFT network adds.
When you look at a SWIFT copy: blocks 1, 2, and 5 are plumbing you don't need. Block 3 holds the UETR. Block 4 is the actual payment.
02/ The fields that actually matter
Block 4 has up to 28 numbered fields, but only a handful do the real work and appear on every wire:
- :20: the bank's internal reference for this transaction
- :32A: the value date, currency, and amount
- :50: who's sending the money
- :57: the beneficiary's bank
- :59: the beneficiary (their account + name)
- :70: the note to the beneficiary (e.g. invoice number)
- :71A: who pays the fees —
OUR(sender),SHA(shared), orBEN(beneficiary)
These are the fields the beneficiary cares about. The UETR (in Block 3 above) is what you care about for tracking.

{5:{CHK:000000000000}}In plain English, this MT103 says: on 27 May 2026 at 12:00, SENDBANKAA (the sending bank) sent USD 25,000 to RCVBANKA (the receiving bank). The money is from ACME Exports Limited, account 12345678, going to Global Imports Inc, account 87654321, against invoice INV-2026-0421. The sender is paying all the fees (OUR). The UETR to track it is 6f8d3a2b-1c44-4f8e-9b21-7d2c9f0a1b22.
04/ Why MT103 is being phased out
SWIFT is replacing MT103 with a newer message format called pacs.008, defined by the ISO 20022 standard. The reason is that MT103 is a 1970s-era plain-text format with tight character limits, while pacs.008 is a modern XML structure that can carry much richer information — full beneficiary addresses, structured purpose codes, more remittance text. SWIFT's cross-border migration programme, CBPR+, completes in November 2025.
Important for you: the UETR works the same in both. Inside MT103 it sits in field 121 (Block 3). Inside pacs.008 it has a slightly different home, but it's the same 36-character tracking number. The wire itself behaves identically — only the envelope changes.
How to get an MT103 SWIFT copy from your bank
A SWIFT copy (MT103 advice, MT103 confirmation) is a PDF or printout of the actual MT103 message your bank dispatched. It is the document trade-finance counterparties, beneficiaries, and auditors ask for.
Identify the wire
Have the date sent, the amount, the currency, and the sending bank's customer reference (field 20) ready. Your online banking transaction ID usually maps to field 20.
Open the request
Business accounts: relationship manager or 'request SWIFT copy / MT103 copy' workflow in the corporate banking portal. Retail accounts: branch visit or secure-message ticket. Phone is slowest.
Specify 'MT103' explicitly
Some staff offer a payment receipt or debit advice instead. Those do not show the UETR or field-level SWIFT structure. Ask for 'the SWIFT MT103 copy with field 121 UETR'.
Confirm and track by UETR
Most banks deliver within 1–3 business days. When you receive the document, copy the 36-character UETR from field 121 and paste it into uetr.ai to monitor the gpi tracker.

FAQ
Frequently asked questions about MT103
What is MT103?
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.
What is MT103 in banking?
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 proof a payment was released over SWIFT. MT103 advices are commonly used in trade finance, real-estate closings, payroll, and supplier payments where a beneficiary needs evidence the payment is in the SWIFT network.
What is an MT103 SWIFT message?
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).
What is MT103 swift confirmation?
An MT103 SWIFT confirmation is the printout (PDF or paper) of the actual MT103 message your sending bank released. It confirms the payment was dispatched over the SWIFT network and shows every field, including the UETR. It is commonly requested as evidence in trade finance, by beneficiaries, and by counterparties who want to confirm payment was sent.
What is MT103 wire transfer?
An MT103 wire transfer is an international wire that has been sent over the SWIFT network using the MT103 message type. Most cross-border bank wires (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.
What is field 121 in MT103?
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 22 November 2018. On a printed MT103 advice it appears as '{121:6f8d3a2b-1c44-4f8e-9b21-7d2c9f0a1b22}'.
How do I get an MT103 SWIFT copy from my 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 1–3 business days; some charge a fee for paper copies.
MT103 vs MT202: what's the difference?
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.
Is MT103 the same as pacs.008?
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-payments migration to ISO 20022 (FINplus / CBPR+) is scheduled to complete in November 2025, after which MT103 is retired for cross-border traffic.
What is MT103 copy?
An MT103 copy (also called a SWIFT copy, MT103 advice, or MT103/202 copy) is a PDF or printout of the actual SWIFT message your sending bank dispatched. 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.
Can MT103 be cancelled or recalled?
Once an MT103 has been released and accepted by the beneficiary bank, it usually cannot be unilaterally cancelled by the sender. A recall is possible via the SWIFT MT192 (Request for Cancellation of a Customer Transfer) or the ISO 20022 pacs.004 (Payment Return) message, and requires the beneficiary bank's cooperation. Most recall requests succeed only if funds have not yet been credited to the beneficiary account.
Is MT103 proof of payment?
An MT103 advice is evidence that a payment instruction was released over the SWIFT network by the sending bank. It is not proof that the beneficiary has received the funds — that is shown by the pacs.002 ACSC (Settled) or ACCC (Credit confirmed) status returned by the beneficiary bank into the SWIFT gpi Tracker, identified by the UETR.
How long does an MT103 take?
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.
