Frequently Asked Questions
Common questions about IBANs, our generator, and how to use test IBANs safely.
What is an IBAN?
The International Bank Account Number (IBAN) is a standard (ISO 13616) used in many countries to identify bank accounts. It includes a country code, check digits, and a domestic account identifier (BBAN). Each country defines its own length and structure.
Are the generated IBANs real?
No. Our tool generates IBANs that are structurally valid (correct length, format, and MOD-97 checksum) but do not correspond to real bank accounts. They are for testing, development, and education only.
Can I use these IBANs for real payments?
No. You must never use test IBANs for real transactions. They are not linked to any real account and must only be used in test environments, demos, or learning.
What is MOD-97 validation?
MOD-97 is the checksum algorithm defined in ISO 13616 for IBANs. The entire IBAN (after moving the first four characters to the end) is treated as a large integer; if the remainder when divided by 97 equals 1, the checksum is valid. Our generator only outputs IBANs that pass this check.
Which countries are supported?
We support 45+ countries, including all SEPA countries (e.g. Germany, France, Italy, Spain, Netherlands, Belgium, Austria, Portugal), the United Kingdom, Switzerland, Turkey, Saudi Arabia, UAE, and many others. The list follows the SWIFT IBAN Registry.
Why do IBAN lengths differ by country?
Each country defines its own IBAN length and the structure of the BBAN (domestic part). For example, Norwegian IBANs are 15 characters, while Maltese IBANs are 31. Our generator respects each country’s official format.
Do you store or log the IBANs I generate?
No. Generation is done on request and we do not store the generated IBANs. The site is stateless; we do not require registration or track which IBANs you generate.
Can I use this in automated tests?
Yes. You can call our country pages or use the generator in headless flows. Please respect our servers (e.g. avoid excessive request rates). For fully offline tests, consider generating IBANs once and hard-coding samples.
What is the difference between IBAN and SWIFT/BIC?
IBAN identifies a bank account. SWIFT/BIC (Bank Identifier Code) identifies the bank or branch. International transfers often require both: BIC for routing, IBAN for the account.
Is the service really free?
Yes. GenerateRandomIBAN.com is free to use. We do not charge for generating IBANs and we do not require an account or sign-up.
How do I copy the generated IBAN?
Use the "Copy" button next to the displayed IBAN. It will copy the value to your clipboard. If your browser does not support the Clipboard API, the button may not work in some environments.
Why is my language not available?
We currently offer the interface in English, French, Spanish, Portuguese, Italian, Russian, Chinese, and Arabic. You can switch the language via the header. More languages may be added later.
Can I generate IBANs for multiple countries at once?
The generator produces one IBAN per page. To get IBANs for several countries, open the relevant country pages (e.g. German IBAN, French IBAN) in separate tabs or use the country list on the home page.
Where can I find the official IBAN specification?
The IBAN standard is ISO 13616. The SWIFT IBAN Registry publishes the exact format (length, structure) for each country. Our implementation follows that registry.
Do you support validation of existing IBANs?
This site focuses on generation. For validation, you can use the same MOD-97 algorithm or dedicated validation libraries in your programming language.
How can I get API access for programmatic IBAN generation?
We offer API access for developers who need to generate valid test IBANs in automated flows (e.g. CI/CD, integration tests, or back-office tools). To request access, please visit our API and contact us at the email provided there.
