FAQ
What is an IBAN?
International Bank Account Number โ a standardized format used to uniquely identify a bank account for international transfers.
What algorithm does this use?
The MOD-97-10 checksum algorithm defined by ISO 13616. It rearranges the country code and account details into a numeric string, and the IBAN is valid if that number mod 97 equals 1.
Can this confirm a real bank account exists?
No. This tool only validates the IBANโs format (checksum). Only your bank can confirm whether an account actually exists.
