International Bank Account Number (IBAN)

Attention!
Bank/Branch Codes and Account Numbers are
NOT checked for validity und existence!
Only competent bank institutes can
officially generate or validate an IBAN!

The IBAN is composed of the Country Code (ISO 3166), a 2-digit checksum and the Basic Bank Account Number (BBAN, ISO 13616).

The BBAN consists of a Bank/Branch Code and the Account Number, both with optional check digits. The exact structure is country specific. See the format table below for details.

To create an IBAN you must first choose the country from the selection bar and type the Bank/Branch Code and the Account Number in the input fields. If you then press the "Create IBAN" button the IBAN appears in the IBAN field.

To check an IBAN you have to type it in the IBAN input field and press the "Check IBAN" button. If it is valid the country, the Bank/Branch Code and the Account Number appears in the corresponding fields.

If any input is invalid a message box appears and the destination fields of the action are cleared.

For examples of International Bank Account Numbers see the examples table below. There is one example for each country.

Alternatives of certain IBAN (*)

In case of the checksums 97 and 98 there is a possible alternative IBAN. It contains the checksum 00 instead of 97, or 01 instead of 98, respectively. Both checksums are validated as correct. It depends on the bank institute which one is the official.

Alternative IBAN with the checksums 00 and 01 are rather unusual. In most cases the checksums 97 and 98 are used.
