pacs.008 (FIToFICustomerCreditTransfer) is the ISO 20022 XML message used to instruct a customer credit transfer between two banks. It is the modern replacement for the legacy SWIFT MT103.
Details
ISO 20022 carries far more structured data than MT103: explicit ordering customer, ultimate beneficiary, structured remittance information, regulatory reporting, structured addresses, and so on. This unlocks better compliance, automated reconciliation, and richer analytics.
On the SWIFT network, ISO 20022 and MT103 are coexisting until November 2025 (the SWIFT MT/MX coexistence end date). After that, customer credit transfers must be sent natively as pacs.008.
A pacs.008 message contains the same UETR as the equivalent MT103 — Ohmyfin tracks both formats interchangeably.
