What is an ACH Return Code?

An ACH return code is a standardized code used to explain why an Automated Clearing House (ACH) transaction was returned by the receiving bank.

Codes are issued by the Receiving Depository Financial Institution (RDFI) and maintained by Nacha, the organization that governs the ACH Network. Certain codes may apply to consumer accounts, non-consumer (business) accounts, or both. These codes help banks, payment processors, and originators understand what went wrong during an ACH transaction so they can determine the appropriate next steps, such as retrying the payment, correcting information, or contacting the customer.

Why you're seeing ACH Return Code R26

Code R26 means there was an error in a mandatory field on the ACH entry. Mandatory fields are required for the ACH Network to process a transaction, and this return may have occurred because:

• Required information was missing. One or more mandatory fields—such as the account number, routing number, transaction code, or amount—were not provided.
• Mandatory data was present but invalid. A required field contained incorrect, incomplete, or improperly formatted information.
• The entry failed basic ACH validation rules. The transaction did not meet minimum formatting or data requirements needed for processing.
