The most appropriate way to confirm your account number, your bank’s country of origin, and any other bank account information that you might deem necessary, is by using IBAN.
The code is compared to the IBAN register when you make a payment to check that the recipient is correct.
The transaction will fail if you input an IBAN improperly, and there is no account associated with that. However, if a corresponding account exists, the transaction will still go through. The bank will need the recipient who received the funds erroneously to approve the reversal.
Most banks opt to use an IBAN checker, also called an IBAN lookup, to deter the errors. This tool ensures that genuine IBANs are error-free.
