The Micro-Entry Rule defines and standardizes practice and formatting of Micro-Entries, which are used by some ACH Originators as a method of account validation.

Phase 2 of this Rule will be effective March 17, 2023

• Originators of Micro-Entries will be required to use commercially reasonable fraud detection, including the monitoring of Micro-Entry forward and return volumes

This rule supplements previous ACH Security Framework data protection requirements by explicitly requiring large, non-FI Originators, Third-Party Service Providers (TPSPs) and Third-Party Senders (TPSs) to protect deposit account information by rendering it unreadable when it is stored electronically.

These changes will amend the Nacha Operating Rules (Rules) to address a variety of minor topics related to Meaningful Modernization, an ACH Operator edit and expiration of stop payments on non-consumer accounts.

The overarching purpose of these two Rules is to deter and prevent, to the extent possible, the improper use of reversals and the harm it can cause.

The two Rules explicitly address improper uses of reversals, and improve enforcement capabilities for egregious violations of the Rules.

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.

The WEB Debit Account Validation Rule became effective March 19, 2021. The rule was originally approved by Nacha members in November 2018 to become effective January 1, 2020.

An industry resource – the ACH Contact Registry - was created for financial institutions to be able to more easily connect with other financial institutions about ACH operations, exceptions and risk management. In order for the ACH Contact Registry to be a valuable, Network-wide resource, all financial institutions participating in the ACH Network need to participate. This rule enables the creation of this resource by requiring the registration of contact information by all financial institutions that participate in the ACH Network.

This Rule increases the speed of funds availability for certain Same Day ACH and next-day ACH credits.

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.

These ballots amend the Rules to address a variety of minor topics. Minor changes to the Rules have little-to-no impact on ACH participants and no significant processing or financial impact.

This rule changes the structure of the audit requirement within the Rules, but does not change the requirement to conduct a Rules compliance audit annually.  

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.

Nacha has adopted a Rule to provide a new, ubiquitous capability for moving ACH payments faster. The Rule will enable the same-day processing of virtually any ACH payment. 

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.

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.
