The IBAN Validator is designed to validate and verify the accuracy of an International Bank Account Number (IBAN).
Data Sources
Some national banks regularly provide official bank sort code lists and checking algorithms for account numbers. In Germany, for example, these lists are officially provided by the Bundesbank and updated every 3 months.
For the IBANs of these countries, more intensive checks can be carried out than for the IBANs of countries that do not provide this information.
