Fedwire® Funds Service ISO® 20022 Implementation Center

FRFS adopted the ISO 20022 message format for the Fedwire Funds Service in a single-day implementation strategy on July 14, 2025. With this implementation, we sunset the existing proprietary Fedwire Application Interface Manual (FAIM) format and replaced all FAIM messages with ISO 20022 messages. Use the links below to access more resources and information.

If you are having difficulty sending or receiving ISO 20022 messages through the Fedwire Funds Service post-implementation, please contact the Support Center.

Contingency resources

In the event that your financial institution is not able to send or receive ISO 20022 messages through the Fedwire Funds Service, please reference the contingency strategies below. For additional assistance, contact the Support Center.

  • Establish new or validate existing correspondent banking arrangements (e.g., bankers’ bank, corporate credit union) through which you may send and receive payment messages.
  • Ensure you have sufficient trained staff to send ISO 20022 messages through the FedPayments® Manager – Funds application via the FedLine Advantage® Solution (i.e., manual entry message screens or import/upload feature).
  • Increase staffing for manual processing of payments, including processing by upstream and downstream applications (e.g., ancillary systems like OFAC and fraud screening).
  • Ensure staff reviews procedures for manually processing incoming messages (e.g., treasury management, posting credits to your customers’ accounts, reconciliation activities).
  • Explore the use of an ISO 20022 message translation service.

FRFS is providing information on actions to take to prepare for the ISO 20022 transition and potential contingency strategies for your convenience only. Your institution is responsible for developing its own contingency plans, and FRFS assumes no liability if your institution is unable to send or receive ISO 20022 or other payment messages.
