What is an IBAN calculator?

Unlike an IBAN checker, which checks if an IBAN is correct by confirming information such as the BIC/SWIFT code, bank name, address, and country, a calculator is used to calculate exact bank account information for those who need to find an IBAN.

Banks arrange national or local account details into a string of alphanumeric characters and so IBAN calculators are used to convert this information into the International Bank Account Number needed when transferring funds to an international account.

  • Check number – A two-digit code used as a redundancy check to detect errors in identification numbers

  • Bank identifier – The unique identifier for the domestic bank

  • Account number – The bank account identifier

Who uses IBANs?

The system was originally developed by the European Committee of Banking Standards (ECBS) in 1997, as a way of creating a standardized method of identifying international bank accounts. The system has since been adopted by banks and financial institutions in countries all over the world, with 80 regions now using IBANs.
