Validate or generate IBANs

Check format + MOD-97 checksum on any IBAN, or generate test IBANs for a country code. Never sends your input anywhere - entirely client-side.

Generate test IBAN

For testing and seed data only - do not use generated IBANs in production payments.

Validation uses the standard MOD-97 algorithm over the IBAN spec. Generated IBANs are real-looking but random - they will pass format checks but won't correspond to any actual account.
