Automated Clearing House

The Automated Clearing House (ACH) is the primary system that agencies use for electronic funds transfer (EFT).


Final Rule on ACH:

On September 11, 2017, the Department of Treasury's Fiscal Service published a final rule at 31 CFR Part 210, "The Federal Government's Participation in the ACH."

The regulations for ACH are in 31 CFR Part 210.

Those regulations define both the rights and liabilities of all the people involved in the ACH system: government agencies, Federal Reserve banks, financial institutions, and the public. The regulations cover ACH credit entries, debit entries, and entry data that an agency starts or receives through the ACH system.

31 CFR Part 210 also includes the interim final rule that allows agencies to deliver federal payments to prepaid debit cards.
