NACHA Operating Rules

Establishing Governance for the ACH Network

Making Electronic Payments Possible

Overview Icon

The ​NACHA Operating Rules, administered by NACHA since 1974, 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.

Your voice strengthens the Rules. Because the Rules are a living document, NACHA depends on user input to amend and update them. A deliberative and inclusive process, similar to that used by Federal agencies under the Administrative Procedures Act, allows ACH Network participants such as banks, credit unions, businesses, consumer advocates, government organizations and industry providers to comment on proposed rule changes. The Rules work in concert with applicable laws and regulations, providing a legal and business foundation for using ACH payments.
