Same Day ACH Testing Begins Summer 2017

April 18, 2017

To FedACH® Services Customers:

The September 15, 2017, implementation date of Same Day ACH Phase 2 will enable ACH Network participants to benefit from same-day processing and settlement of qualified ACH debits in addition to ACH credits. Additionally, as we announced last week, the U.S. Treasury has committed to participating in Same Day ACH beginning September 15, 2017, in a phased implementation1. The first phase will provide for the receipt of tax and non-tax Same Day ACH credits by the federal government. Additional Same Day ACH origination capabilities will be adopted by the Treasury throughout 2017 and 2018. ACH origination software vendors and third-party processors providing ACH origination services should be prepared to support the receipt of Same Day ACH credits by federal government RTNs by September 15, 2017.

In preparation for Phase 2 implementation of Same Day ACH, customer testing will be conducted in a series of waves based on connection type. FedACH Services will begin testing in early summer of 2017. ACH file testing will be supported Tuesday through Friday of each week from 9:00 a.m. ET to 5:00 p.m. ET.

Customers will be contacted via email according to their defined waves approximately 45 days in advance of testing windows. Included in this more detailed communication will be a testing script that will support customers during their Same Day ACH testing efforts. Testing will consist of sending and receiving test files to validate back end processing. Included with this communication is a complete list of accounting transaction codes (PDF) that can be used to prepare for testing even before receiving detailed test scripts.

Additional supporting documentation is posted in the Same Day ACH Resource Center which includes information on both Phase 1 and Phase 2 implementations for the following categories:

  • Billing Product Codes and Accounting Transaction Codes – this section provides the billing product codes for NACHA’s Same Day Entry Fee and the accounting transaction codes for Same Day ACH debits and credits
  • Frequently Asked Questions – based on customer feedback and inquiries, this section provides a robust series of questions and answers on a wide range of Same Day ACH topics
  • FedACH Processing Schedule – this section shows the transmission windows, target distribution times and settlement schedules

Please contact FedACH and Check Services Customer Support at P: (877) 372-2457 with questions. We appreciate your support and look forward to continuing to provide you with high-quality and efficient payments services.


1 Treasury’s participation remains dependent on the adoption of a final 31 CFR Part 210 rule.
