What a valid IBAN from Croatia does not prove

Formal validity is a strong signal against input errors, but it is not real-time confirmation of an account.

No existence confirmation

The account may be closed or unreachable.

No account-holder match

A person or company name is not compared with the IBAN.

No payment guarantee

A valid IBAN does not guarantee that a payment will be accepted.

Bank data can change

Privacy: The input is transmitted only for validation and is not placed in the page URL.
