2019 NACHA Operating Rules & Guidelines

The ACH Network is thriving, moving an estimated 23 billion payments and transferring $50 trillion in 2018. As ACH payments become faster and smarter, amendments to the NACHA Operating Rules addressed expanding the capabilities of Same Day ACH, while also focusing on risk management and compliance.

In 2018, a number of important amendments were made to the NACHA Operating Rules:

• Three rules to enhance Same Day ACH – 1) sooner funds availability; 2) a higher dollar limit; and 3) longer processing hours.

• Four rules to improve risk management and compliance – 1) a return for a questionable transaction; 2) supplementing the fraud detection standards for WEB debits; 3) supplementing the existing data security requirements; and 4) streamlining the presentation of the annual ACH Rules compliance audit.

• Several other minor changes to the Rules include editorial changes to improve clarity or readability of language; changes to correct inconsistencies; changes to clarify intent and minor modifications to reflect current practices.


Access to the Rules & Guidelines helps to identify new opportunities to leverage the ACH Network to meet customer’s needs, while maintaining a clear understanding of network requirements.

The Rules include the legal framework for the ACH Network, and the basic obligations of each ACH Network participant. Additionally, the included appendices contain details on Rules enforcement, annual audit requirements, a complete table of return reason codes and formatting specifications.

The Guidelines expands on the Rules, providing complete discussions of each ACH Network participant type and its role and responsibilities, detailed overviews of the Standard Entry Class Codes and use-case examples in special topic areas, such as Third-Party Service Providers.
