NACHA Compliance

ABA Routing Numbers and NACHA Compliance

NACHA is an industry trade organization and the administrator of the Automated Clearing House (ACH) Network, responsible for authoring ACH operating rules, and performing rules enforcement and risk management. The NACHA Operating Rules provide the legal foundation for the exchange of ACH payments and ensure that the ACH Network remains efficient, reliable, and secure for the benefit of all participants.

Validate ABA Routing Numbers

To reduce the number of administrative returns entered in the ACH Network, NACHA compliance requires companies originating ACH transactions to use commercially reasonable procedures to verify that routing numbers are valid for WEB and TEL ACH transactions.

One way to do this is to verify the length and the check digit of the routing number, and to make sure it is properly formed. However, this verification/validation will not prevent the use of numbers that pass the verification even though they are retired or just plain wrong.
