NACHA Operating Rules

The ​Nacha Operating Rules are the foundation for every ACH payment. By defining the roles and responsibilities of financial institutions and establishing clear guidelines for each Network participant, the Rules ensure that millions of payments occur smoothly and easily each day.

Featured Rules

Return for Questionable Transaction

This change to the Nacha Operating Rules will enhance quality and improve risk management within the ACH Network by allowing RDFIs to indicate within a return that the original transaction was questionable or part of anomalous activity.

Differentiating Unauthorized Return Reasons

This rule better differentiates among types of unauthorized return reasons for consumer debits. This differentiation will give ODFIs and their Originators clearer and better information when a customer claims that an error occurred with an authorized payment, as opposed to when a customer claims there was no authorization for a payment. ODFIs and their Originators should be able to react differently to claims of errors, and potentially could avoid taking more significant action with respect to such claims.

ACH Network Risk and Enforcement Topics

This Rule will improve the overall quality of the ACH Network by reducing the incidence of returned Entries and the associated costs, both financial and reputational, that such returned Entries impose on the ACH Network and its participants. The approach to reducing risk with this Rule is multi-fold, as described by the various topics below. These changes are also expected to increase customer satisfaction with the ACH Network by reducing the volume of transactions subject to customer disputes.

Disclosure Requirements for POS Entries

This Rule establishes an Originator/Third-Party Service Provider obligation to provide consumer Receivers with certain disclosures when providing those consumers with cards used to initiate ACH Point of Sale (POS) Entries.

Third-Party Sender Registration

DEADLINE for initial registration is March 1, 2018.
This rule requires Originating Depository Financial Institutions (ODFIs) to identify and register their Third-Party Sender customers. The registration process promotes consistent customer due diligence among all ODFIs, and serves as a tool to support Nacha’s continuing efforts to maintain ACH Network quality.

Improving ACH Network Quality - Unauthorized Entry Fee

This rule is intended to improve ACH Network quality by reducing the incidence of ACH debits that are returned as unauthorized. Under this Rule, an ODFI will pay a fee to the RDFI for each ACH debit that is returned as unauthorized (return reason codes R05, R07, R10, R29 and R51). ODFIs will have an economic incentive to improve the quality of the ACH transactions they originate. RDFIs will be compensated for a portion of the costs they bear for handling unauthorized transactions, and will experience reduced costs due to a reduction in unauthorized transactions over time.
