# What is an MT103

MT103 is the SWIFT FIN message format for a single customer credit transfer — the standard "wire" message that moves money across borders in the legacy MT (Message Type) standard. It is being migrated to the ISO 20022 pacs.008 XML equivalent during the CBPR+ transition. Key fields: 20 (sender's reference), 23B (bank operation code), 32A (value date, currency, amount), 50K/50A (ordering customer), 57A (account with institution), 59 (beneficiary), 71A (charges), 121 (UETR). Look up an MT103 by its UETR at https://ohmyfin.org.
