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 R13

Code R13 means the routing number provided for the ACH entry is not valid. This may have occurred because:

• The routing number was entered incorrectly. A missing or incorrect digit caused the routing number to fail validation.
• The routing number is not enabled for ACH. Some routing numbers printed on checks (ABA routing numbers) are valid for paper checks but not for ACH transactions.
• The routing number is outdated or inactive. The bank or branch associated with the routing number is no longer valid for ACH processing.
