Fedwire® Funds Service Release DIT2 Peer-to-Peer Request Form and Test Schedule
In preparation for the Fedwire Funds Service ISO® 20022 November 2027 release, mandatory testing group participants are required to participate in at least two peer-to-peer testing sessions in the second Depository Institution Testing (DIT2) environment to ensure readiness. All other participants are highly encouraged to test; peer-to-peer testing allows you to test the November 2027 release changes, verify message integrity and reconcile your Fedwire Funds Service activity as you would on a normal processing day to ensure your organization is ready for the upcoming release. We encourage you to participate in all six testing sessions, if possible.
On the day of testing, participants should:
- Simulate a typical business day in the DIT2 environment
- Successfully complete the Test Case Scenario document (available via the MyStandards® portal by the Swift® service)
- Conduct additional use cases as needed with your testing partner(s)
