High-Priority Return Code

This is a common ACH return code that usually indicates a data entry error in the account number, routing number, or account holder name. Unlike permanent closures, this is typically fixable by verifying and correcting the account information.

‍

Error message: "The account number structure is valid and it passes the check digit validation, but the account number does not correspond to the individual identified in the Entry, or the account number designated is not an open account."

What Causes ACH Return Code R03?

The R03 ACH return code means "No Account/Unable to Locate Account" and indicates that the receiving bank couldn’t find an account matching the details submitted in the ACH transaction. This typically happens due to incorrect or mismatched information - such as a mistyped account number, a non-existent account, or discrepancies in the account holder's name.

Unlike R01 (insufficient funds), which involves a valid but underfunded account, or R02 (account closed), which deals with accounts that previously existed, R03 means the payment details do not match any recognizable, active account in the bank’s system - even if the account number format appears valid.

Can You Retry R03 Payments?

Yes, but only after verifying and correcting the account information. Since the issue stems from incorrect or mismatched data, retrying with the same details will result in another return. You’ll need to contact the customer, confirm their banking information, and ensure everything matches exactly - including account holder name, number, and routing details.

Common Causes

Typos in the account number or routing number

Account holder name doesn't match bank records exactly

Account is inactive, dormant, or temporarily restricted

Bank merger or acquisition changed account structure

Account exists but is not eligible for ACH transactions

Key Information
