Frequently asked questions
What is an MT103?
MT103 is the SWIFT message type used to instruct a single customer credit transfer between banks. It contains the sender, beneficiary, amount, currency and references.
How do I know if an MT103 is real?
Always verify the UETR (field 121) before releasing goods or services. If the UETR cannot be located in the SWIFT network, the MT103 may be fraudulent — wait until your own bank confirms the credit.
What is field 20 vs field 121?
Field 20 is the sender bank reference (free-text, up to 16 chars). Field 121 is the UETR (36-character UUID, mandatory since 2018). Ohmyfin accepts either, but UETR gives the most accurate result.
Is MT103 being replaced?
Yes. SWIFT MT/MX coexistence ends in November 2025, after which customer credit transfers move to ISO 20022 pacs.008. Ohmyfin tracks both formats with the same UETR.
Can scammers fake an MT103 PDF?
Yes — fake MT103 PDFs are a common business-email-compromise tactic. Always verify the UETR in Ohmyfin rather than trusting a screenshot or PDF.
