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 R77
Code R77 means the ODFI is refusing to accept an R62 dishonored return sent by the RDFI. This return indicates that the originating bank disputes the receiving bank's claim that a previously returned entry was improperly returned. This may have occurred because:
- The ODFI believes the original return was valid. The originating bank maintains that its initial return was proper and should not have been dishonored by the RDFI.
- The ODFI has documentation supporting its original return. Records and transaction history demonstrate that the original return reason was accurate and complied with ACH rules.
- There is a dispute about the facts underlying the return. The ODFI and RDFI disagree about account status, authorization, or other factors that led to the original return.
