IBAN Generator – valid SEPA test IBANs for developers & QA

Yes. Every IBAN is calculated per ISO 13616 with the MOD-97 algorithm. It passes any technical format and checksum test in banking software, ERP systems, SEPA libraries and online validators.

No. The bank codes are modeled after real banks, but the account numbers themselves are randomly generated and do not belong to any real account. The data is intended exclusively for tests, demos, training and mock data.

All 37 SEPA countries, from Andorra through Germany and France to Vatican City. The official IBAN specification is stored for each country — including the country-specific BBAN structure, bank code format and valid example BICs.

Typical use cases: developing and testing banking and accounting software, load tests for SEPA direct debit pipelines, QA of web forms with IBAN validation, UI demos, automated tests, training and demo datasets.

MOD-97 is the IBAN's international checksum. It protects against typos: swapped or changed digits very likely produce an invalid remainder. Any test IBAN generator that skips MOD-97 will fail at the very first validation step.

The BIC (Business Identifier Code) identifies a bank internationally. Within the EU it has not been mandatory for SEPA transfers since 2016, but many systems still require it. The generator provides a matching example BIC for every IBAN.

Yes. Usage is completely free and no signup is required. The generated data never leaves your browser — calculation runs entirely client-side in JavaScript.

The CSV export button produces a CSV file with the currently visible IBANs and columns for IBAN, country, country code, BIC and bank. You can import it directly into Excel, LibreOffice, databases or test frameworks.
