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 R19
Code R19 means there was an issue with the amount field on the ACH entry, preventing it from being processed. This may have occurred because:
- The amount field was non-numeric or improperly formatted. The dollar amount may have included invalid characters, missing digits, or an incorrect number of decimal places.
- The amount was zero when a non-zero amount was required. Certain ACH entries, including most debit and credit transactions, cannot be submitted with a zero-dollar amount unless explicitly permitted by the SEC code.
- The amount exceeded limits for the SEC code used. Some SEC codes or entry types impose maximum dollar thresholds, and amounts above those limits are automatically rejected.
