High volume ACH originators who originate over two million items annually across all their origination banks must protect bank account numbers by rendering them unreadable when stored electronically.

Phase 1 – September 16, 2022
2021 ACH rule changes
Implemented March 19, 2021
If you originate ACH debits using the WEB SEC code, you will need to validate account information for new transactions and modifications to existing transactions that are originated on March 19, 2021 or later. The rule change does not require a specific validation method be used. Some examples of possible validation methods are prenotes, micro-deposits or validation services offered through partnerships with third parties. Please contact your Treasury Management Sales Consultant for additional information on the account validation options available at U.S. Bank.
Important Update: On Oct. 19, 2020, Nacha published ACH Operations Bulletin #7 to address COVID-19 relief for the ACH network. In the bulletin, Nacha confirmed that they will not enforce the Supplementing Fraud Detection Standards rule for an additional period of one year from the effective date, with respect to covered entities that are working in good faith toward compliance, but that require additional time to implement solutions. Nacha strongly encourages all such covered entities to work towards compliance as soon as possible. Please contact your Treasury Management Sales Consultant for additional information on the account validation options available at U.S. Bank.

The five new rules will be:
- More explicitly define standing authorizations for ACH debits
- Allow for oral authorizations beyond the traditional phone call
- Clarify ACH authorization standards across payment initiation channels
- Reduce the burdens associated with providing proof of authorizations
- Facilitate the use of electronic and oral Written Statements of Unauthorized Deb
Implemented March 19, 2021
This new rule expands access to Same Day ACH by allowing Same Day ACH transactions to be submitted to the ACH Network for an additional two hours every business day. The new Same Day ACH processing window will go into effect on March 19, 2021.

These originators will need to review and potentially update their data security efforts to be in compliance by June 30, 2021. In 2022, all originators who originate over two million items annually will be required to protect bank account numbers in the same manner. These originators must be in compliance by June 30, 2022.

The Reversals rule change establishes that the initiation of reversals or reversing entries can only be done for reasons outlined as permissible under the ACH rules. The Reversals rule also explicitly defines specific examples where the initiation of a reversal would be improper, such as reversing payroll transactions due to the Originator or Third-Party Sender failing to fund the entries.
