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 R27

Code R27 means there was an issue with the trace number associated with the ACH entry. The trace number is used to uniquely identify a transaction within the ACH Network, and this return may have occurred because:

  • The original entry trace number was missing from the addenda record. Returns and Notifications of Change must reference the trace number of the original transaction.
  • The trace numbers did not match. The trace number in the addenda record did not match the trace number in the corresponding entry detail record.
  • The trace number was improperly formatted. The value did not meet ACH formatting or structure requirements.
