How to verify an MT103 payment copy
By the Vanguard Verify desk · Published 2026-10-24 · Updated 2026-10-24
Short answer: a PDF or screenshot of an “MT103” proves nothing on its own. The only real verification is your own bank confirming that the funds have been credited to your account. If the payment was sent over Swift, ask the sender for the UETR (the 36-character Unique End-to-end Transaction Reference) and give it to your bank so it can trace the payment.
What an MT103 is
MT103 was the Swift message type for a single customer credit transfer, the standard instruction one bank sent to another to pay a business or person abroad. Swift ended the coexistence period for cross-border payment instructions on 22 November 2025; since then payment instructions over Swift must use ISO 20022 messages, where pacs.008 carries the customer credit transfer. Many traders still say “MT103” to mean “Swift payment confirmation”, so you will keep seeing the term in deals.
Step-by-step check
- Do not release goods or documents on a copy. A message copy can be typed in any word processor. Treat it as information, not as payment.
- Ask for the UETR and the sending bank’s BIC. Swift says every payment instruction carries a UETR that the sender issues and that cannot be altered, and intermediary banks must pass it on unchanged.
- Check the BIC yourself in Swift’s free BIC search. The bank name and country must match what the sender claims.
- Ask your own bank, through your usual relationship contact, to trace the payment with the UETR. Your bank can see whether funds arrived, are in process, or were rejected.
- Confirm credit on your own account statement or online banking. That is the only proof that matters.
- Never call phone numbers or email addresses printed on the copy to “confirm” it. Find the bank’s contact details from its official website.
Genuine vs suspicious
| Item | Genuine payment | Warning sign |
|---|---|---|
| Proof | Funds visible on your own account | Only a PDF, screenshot or “screen copy” |
| Reference | UETR your bank can trace | No UETR, or one your bank cannot find |
| Process | Sender pays, you check with your bank | Sender asks you to pay a fee to “release” or “activate” the funds |
| Wording | Plain transfer details | Terms such as “MT103/23”, “one-way”, “two-way”, “server-to-server” or “IP/IP” |
Red flags
- Pressure to ship, sign a bill of lading over, or hand over documents “because the MT103 has been sent”.
- Requests for an advance fee, tax or “compliance charge” before the money can land.
- Large sums “sent” by a third party that is not your contract buyer.
- Unusual jargon about “cash transfers via Swift” that your own bank does not recognise.
- A copy that names a bank, but the bank’s official contacts say they have no record.
Payment copies are often paired with other bank-message claims. See what an MT799 really is and why an MT799 is not proof of funds.

FAQ
Is an MT103 copy proof of payment?
No. A copy can be fabricated. The proof is your own bank confirming the funds were credited to your account.
What is a UETR?
A Unique End-to-end Transaction Reference: a 36-character reference carried in every Swift payment instruction, issued by the sender and passed unchanged along the chain so the payment can be tracked.
Does MT103 still exist?
Swift ended the MT/ISO 20022 coexistence for cross-border payment instructions on 22 November 2025, so payments now travel as ISO 20022 messages such as pacs.008. People still use the name MT103 informally.
