This ACH return code indicates that the bank account information provided for the transaction was incorrect or invalid. R56 returns occur when the account details don't match the receiving bank's records, preventing successful processing. This code appears to be rarely used in modern ACH processing and may be deprecated in favor of more specific return codes like R03 or R04.
Error message: "The transaction was returned because incorrect bank account information was provided."
What Causes ACH Return Code R56?
The R56 ACH return code means "Incorrect Bank Account Information" and indicates that the bank account details provided for the transaction don't match the receiving bank's records. This return occurs when there are discrepancies in the account information that prevent the receiving bank from properly identifying or accessing the intended account.
Unlike more specific return codes like R03 (No Account/Unable to Locate Account) or R04 (Invalid Account Number), R56 appears to be a broader category for general account information errors. However, this return code is rarely encountered in modern ACH processing, as most banks now use more specific return codes to identify particular types of account data errors.
Can You Retry R56 Payments?
You can retry R56 payments after correcting the incorrect bank account information. Before reprocessing, verify all account details including account number, routing number, and account type with the recipient. Since this return indicates a data accuracy issue rather than authorization or funds availability problems, correcting the information should resolve the issue.
How to Respond to an R56 Code
An R56 return requires immediate verification and correction of the bank account information provided, followed by careful validation before reprocessing the payment.
