MT103 is the SWIFT message type for a single customer credit transfer between two banks. It is the format used for almost every traditional cross-border wire transfer initiated by an individual or corporate customer.
Details
An MT103 contains the sender, beneficiary, amount, currency, value date, charges instruction, references, and routing through up to four correspondent banks. The full field reference is at /swift-fields.
The MT103 is gradually being replaced by ISO 20022 pacs.008 as part of the global migration finishing in November 2025, but both formats coexist on the SWIFT network and Ohmyfin verifies either.
Receiving an MT103 PDF from a counter-party is not by itself proof of payment — the document can be forged. Always verify the UETR (field 121) before releasing goods or services.

Frequently asked questions
How can I tell if an MT103 is real?
Verify the UETR (field 121) on Ohmyfin. If the UETR cannot be located in the SWIFT network, treat the document as fraudulent until your own bank confirms the credit.
How long does an MT103 take?
On SWIFT GPI, most MT103 payments settle within minutes to a few hours. Sanctions screening, missing data and time-zone cut-offs can extend it to 1–3 business days.
