ISO 20022 is Coming to Wires

The Fedwire Funds Service is moving to ISO 20022, a new messaging standard being adopted across the industry, on March 10, 2025. This move will create long-term benefits for our increasingly interconnected global economy and is already in use for instant payments via the FedNow Service.

Even though 2025 seems a long way off, it’s important to start preparing now. We recommend connecting with your core processor and other technology vendors to discuss any impact this change may have on your environment.

BBOK is actively collaborating with our partner, Aptys Solutions, to prepare for these changes in PATH.

Examples of impactful changes you can expect to see include:

  • The location of certain data will change
  • The names of fields may change
  • The number of address fields will change from 3 lines of 35 characters to 10 different fields with various character lengths
  • “Originators” and “Receivers” will change to “Debtors” and “Creditors,” respectively

We’re dedicated to being ready for this transition, and we want to make sure that you’re ready too. We will continue to provide updates and resources as the March 10, 2025 go-live date approaches, but you can also find general information about the transition to ISO 20022 at:
