The Fedwire Funds Service ISO 20022 implementation has been rescheduled from March 10 to July 14, 2025. This decision was made after careful consideration of industry requests and assessment of customer readiness.  This reschedule will provide both customer and vendors additional time to better prepare for the transition to the new ISO 20022 format.  

The Fedwire Funds Service will remain on the current message format (i.e., Fedwire Application Interface Manual (FAIM) 3.0.7 format) until July 14, 2025.
