AC03 - Invalid creditor account number

What this code means

AC03 means the creditor account — the beneficiary account you are paying — is not valid. Unlike AC01, which flags a malformed number, AC03 typically means the account exists in form but cannot receive this payment.

Typical causes

• The beneficiary IBAN is well-formed but does not correspond to a real, reachable account.
• The beneficiary changed bank and the account reference on file is stale.
• The account is not enabled to receive SEPA credit transfers.

What to do

Confirm the correct IBAN directly with the beneficiary, update your master data so the stale reference does not come back, and resubmit the payment. This rejection is recoverable.
