Ohmyfin の回答は以下のとおりです（英語）。
pacs.008 is the ISO 20022 XML message used for cross-border customer credit transfers — the modern replacement for the legacy SWIFT MT103. It carries the same payment data plus much richer structured fields (full structured address, regulatory reporting, purpose codes) and becomes mandatory for all SWIFT cross-border traffic in November 2025.
Full name: FIToFICustomerCreditTransferV (Financial Institution to Financial Institution Customer Credit Transfer). Defined in the ISO 20022 standard maintained by ISO/SWIFT.
Structure: XML, with structured blocks for GroupHeader, CreditTransferTransactionInformation (the actual payment), Debtor (sender), Creditor (beneficiary), DebtorAgent (sender's bank), CreditorAgent (beneficiary's bank), IntermediaryAgent (correspondent banks), Amount, ChargeBearer, RemittanceInformation and PaymentIdentification (which contains the UETR).
Why migrate from MT103? pacs.008 supports much longer fields, structured addresses (street/city/postcode/country instead of free text), regulatory reporting codes, and unlimited remittance information. Much better for compliance and STP (straight-through processing).
Migration timeline: SWIFT and CBPR+ require all cross-border traffic to be in ISO 20022 by November 2025. During the migration window banks send and receive both formats.
Tracking: the UETR is in the same place conceptually — the <UETR> element inside <PaymentIdentification>. Ohmyfin treats MT103 and pacs.008 identically for tracking purposes.
