What is an IBAN?

The International Bank Account Number (IBAN) is a standardized international format for bank account numbers.

It was introduced to make payments more reliable and easier to process, especially across Europe. An IBAN usually consists of a country code, check digits and a country-specific account identifier.

What does the IBAN check do?

The IBAN check validates the structure and check digits of an IBAN. Where supported, IBAN-Test can also validate bank and account details and return additional information such as BIC, bank name or bank location.
