Random IBAN Generator

Generate random but structurally valid IBANs for testing, development, and educational purposes. Every generated IBAN passes ISO 13616 MOD-97 checksum validation but does not correspond to any real bank account.

These IBANs are randomly generated for testing purposes only. They are not linked to real bank accounts and must not be used for actual financial transactions.

What Is an IBAN?

An International Bank Account Number (IBAN) is a standardized format for identifying bank accounts across national borders. Defined by ISO 13616, it consists of a two-letter country code, two check digits, and a country-specific Basic Bank Account Number (BBAN). IBANs were introduced to simplify cross-border payments within Europe and have since been adopted by over 80 countries worldwide.

How Is an IBAN Structured?

Every IBAN follows the same general pattern: the first two characters are the ISO 3166-1 country code (e.g. DE for Germany, FR for France), followed by two numeric check digits calculated using the MOD-97 algorithm. The remaining characters form the BBAN, whose length and format vary by country, from 11 characters for Norway to 27 for Malta.

IBAN Formats by Country

Each country that uses IBAN has its own specific format, defined by the SWIFT IBAN Registry. The structure, length, and composition of the BBAN portion vary significantly, from Norway's compact 15-character IBAN to Malta's 31-character format. Below you can explore the IBAN format for each of the 45 supported countries.

Frequently Asked Questions – IBAN Generator

What is a random IBAN generator?

A random IBAN generator creates International Bank Account Numbers that are structurally valid and pass the MOD-97 checksum verification defined by ISO 13616. These IBANs are intended for software testing, form validation, and educational use, they do not belong to any real bank account.

Are the generated IBANs real?

No. The IBANs produced by this tool are randomly generated. While they follow the correct format and pass checksum validation, they are not connected to any actual bank account. They should never be used for real financial transactions.

Can I use these IBANs for testing?

Yes. Randomly generated IBANs are widely used in software development for testing payment forms, API integrations, data validation, and database schemas. They provide a realistic format without exposing real financial data.

How does MOD-97 validation work?

The MOD-97 algorithm is specified in ISO 7064. To validate an IBAN: move the first four characters to the end, replace each letter with its numeric value (A=10, B=11, … Z=35), and compute the remainder when divided by 97. A valid IBAN always yields a remainder of 1.

Which countries are supported?

This tool supports IBAN generation for 45 countries across Europe, the Middle East, North Africa, and Asia, including all Eurozone members, the UK, Switzerland, Turkey, Saudi Arabia, UAE, and more. Each country follows its own BBAN structure as defined in the SWIFT IBAN Registry.
