How do I generate a random IBAN for free?

Choose the country in the selector and click "Generate random IBAN". This free IBAN generator creates a MOD-97-valid number instantly, with no registration or installation.

Can I generate IBANs for several countries?

Yes. The random IBAN generator supports more than 20 SEPA countries, including Spain, Germany, France, Portugal and Italy. Select the country and click generate to get a valid IBAN for that territory.

How is this different from generating an IBAN from a CCC?

This IBAN generator creates random fictitious numbers. The bank account to IBAN converter calculates the real IBAN from your CCC or account data. For real accounts, use the generator at /iban-generator.

Free random IBAN generator

This IBAN generator creates valid ISO 13616 account numbers using the MOD-97 algorithm. Use it to generate random IBANs for testing, demos or learning — not for real payments.

Select the country, click "Generate random IBAN" and you will get a valid IBAN instantly. You can repeat to generate IBANs from different SEPA countries.

Generated IBANs are valid in format (MOD-97) but do not correspond to real bank accounts. Do not use these numbers for transfers or direct debits.

IBAN	ES9631103515195220019994

BIC	CCRIES2A110
Country	Spain

Do you have a real bank account or CCC?

If you need to convert a real account number (Spanish CCC or another national format) to IBAN, use our bank account to IBAN converter. Unlike this random IBAN generator, it calculates the exact IBAN for your account.

What is a random IBAN generator?

A random IBAN generator creates account numbers with valid IBAN format without using real banking data. It applies the MOD-97 algorithm so the result passes standard format checks.

Unlike a CCC to IBAN converter, this generator does not convert your account: it creates fictitious but structurally valid IBANs. Use it for software testing, training or validators, never for payment operations.

How does this IBAN generator work?

For Spain, the generator combines random entity, branch and account data and calculates CCC and IBAN check digits. For other SEPA countries, it generates a random BBAN and calculates MOD-97 check digits until a valid IBAN is obtained.

Each click on "Generate random IBAN" produces a different number. You can generate IBANs for Spain, Germany, France, Portugal, Italy and other SEPA countries from the same form.

Random generator vs bank account to IBAN converter

This random IBAN generator creates fictitious but format-valid numbers. The bank account to IBAN converter, by contrast, transforms your real CCC or account data into the exact IBAN for your account.

If you need IBANs for testing, use this tool. If you need the IBAN of an existing account, visit the CCC to IBAN converter at /iban-generator.

What is random IBAN generation for?

Common use cases for this IBAN generator include:

Testing IBAN integrations and validators in software development
Showing forms or SEPA flows with sample data
Checking that your system accepts IBANs from different countries
Understanding IBAN structure and the MOD-97 algorithm
