수취인의 IBAN 또는 계좌번호가 유효하지 않거나 수취은행에 존재하지 않습니다.
AC01 is the most common SWIFT reject code. It means the account number provided (usually an IBAN) either fails the check-digit validation or does not match any account at the beneficiary bank.
Most AC01 rejections are caused by a single transposed digit in the IBAN. The IBAN check-digit algorithm catches many of these before the payment even leaves the bank — but not all errors are caught at entry.
Funds are returned within 2–5 business days. Get the correct IBAN directly from the beneficiary's bank statement or account-opening letter before resending.
