Are these real IBANs?

No. The IBANs are entirely synthetic. They follow each country's structure and pass the ISO 13616 MOD-97 checksum, but they are not linked to any bank or real account.

An IBAN (International Bank Account Number) is a standardized international numbering system for individual bank accounts. It starts with a 2-letter country code, a 2-digit check number, and a country-specific BBAN (Basic Bank Account Number).

How is the check digit calculated?

The two check digits are computed using the MOD-97-10 algorithm defined in ISO 13616. The BBAN is rearranged so the country code and "00" are appended to the end, then divided by 97. The check digits = 98 minus the remainder.

Can I use these IBANs for real transactions?

No. Banks verify account ownership after structural validation. These fictitious IBANs will be rejected during real payment processing.

Which countries are supported?

The tool covers 20+ countries including Germany, France, UK, Netherlands, Spain, Italy, Belgium, Austria, Switzerland, Portugal, Poland, Sweden, Norway, Denmark, Finland, Ireland, Luxembourg, Greece, Czech Republic, and Hungary.
