What does this website do?


IBAN.com is an online software designed to validate and calculate International Bank Account Numbers (IBAN).

Our software performs various mathematical checksum calculations in order to determine if the IBAN you entered is valid. If the entered IBAN is valid our software attempts to identify the bank owning this account,country,address and BIC code.

The IBAN consists of up to 34 alphanumeric characters, comprising a country code, two check digits and a long and detailed bank account-number used in bank wire transfers. The IBAN structure is defined by the international standard under ISO 13616:1997 and check digits are performed using MOD 97 (ISO 7064).

The IBAN validation engine supports 94 total countries and all 35 SEPA countries. Our system can respectively identify 94 distinct data structures and perform IBAN format, check digit and length validations.

We currently can perform domestic account validation algorithm tests on 37 countries which add a second layer of protection against invalid IBAN data. The bank details database currently contains detailed branch information for 40 countries.
