Fedwire^® Funds Service ISO^® 20022 Testing Requirements

We provided three ISO 20022 testing environments to help ensure that the Fedwire Funds Service community was well prepared for the single-day ISO 20022 implementation that occurred on July 14, 2025. Given the large number of customers, service providers and software vendors we needed to support for ISO 20022 testing, we developed the following testing requirements using a risk-based approach. Please contact our Wholesale Testing Services with any questions.

1. MyStandards Readiness Portal Testing (Until Go-live weekend)
2. Depository Testing Environment (DIT2) Testing (Until Go-live weekend)
   • Opt-in peer testing online form for FedLine Direct and FedLine Advantage customers
   • Federal Reserve Financial Services recommended that all customers test in the DIT2 environment to mimic the traffic they would send in production. 
   • FedPayments Manager — Funds manual entry attestation
   Please note: The DIT2 environment will be on an adjusted schedule for the first week of production (i.e., July 14–18) as noted below:

   Day	Opening Time	Closing Time	Reopening Time
   Sunday, July 13	9:00 p.m. ET	N/A	N/A

3. Saturday Production Testing (2025 ISO 20022 Saturday Production Testing Schedule)
   Note: The test script for each environment and the Testing Attestation Form for the MyStandards Readiness Portal testing are available in MyStandards. No attestation form will be required for DIT2 certification testing; confirmation of testing will be completed by the Wholesale Testing Services.
