Three Phases of the ISO 20022 Implementation for the Fedwire Funds Service
Phase 1
ISO Preparation
(November 23, 2020)
  • Prepare for and simplify the ISO 20022 implementation by “cleaning up” the legacy format.
  • Accommodate SWIFT MT changes to originator and beneficiary fields.
Phase 2 ISO Like for Like (Begins Q1 2022 through Q3 2023)
  • Migrate Fedwire Funds Service participants in waves over 18 months to send and receive the ISO 20022 version of the legacy FAIM 4.0 format.
  • The Fedwire Funds Service will translate the legacy format to ISO 20022 and vice versa when necessary to accommodate Fedwire senders and receivers that are not using the same format.
  • Fedwire Funds Service participants will not be able to send messages using enhancements during this phase; however, they will be required to demonstrate their ability in the Depository Institution Test environment to receive ISO 20022 messages with the enhancements that will go live in Phase 3.
  • Sunset the legacy format at end of this phase.
Phase 3 ISO Enhancements
(Q4 2023)
  • Enable all Fedwire Funds Service participants to send ISO 20022 messages with optional enhancements on a specific date in Q4 2023 to be determined.
