Frequently Asked Questions

An IBAN (International Bank Account Number) is a standardized international numbering system for identifying bank accounts across borders. It consists of a two-letter country code, two check digits, and a country-specific account number that can be up to 30 characters long.
IBAN validation uses the MOD-97 algorithm defined in ISO 13616. The country code and check digits are moved to the end, letters are converted to numbers, and the resulting number is checked to see if it gives a remainder of 1 when divided by 97.
No, this tool validates the IBAN format and check digits only. It confirms the IBAN is structurally correct and mathematically valid, but it cannot verify whether the actual bank account exists or is active.
IBAN is used in over 70 countries, primarily in Europe, the Middle East, and parts of Africa and the Caribbean. Notable exceptions include the United States, Canada, and Australia, which use different account number systems.
