Test IBAN Generator
Generate IBANs with valid mod-97 checksums for DE, GB, FR, ES, IT, NL.
Generate placeholder IBANs (International Bank Account Numbers) with the correct length and a valid mod-97 checksum for six common European countries. They pass format validators but aren't tied to any real bank account, so they're safe for testing.
Common use cases
- Test SEPA payment forms in staging environments
- Validate IBAN-format checks in your accounting integrations
- Populate finance dashboard mockups with realistic IBANs
- Stress-test client-side mod-97 validation
Frequently asked questions
Will banks accept these IBANs?▾
No. They have valid format and checksum but the bank/account portion is random and doesn't correspond to any real account — your bank's lookup will fail.
What's the mod-97 check?▾
Every IBAN's last digits are computed so the rearranged number mod 97 equals 1. We compute it correctly so client-side validators accept the IBAN.
Can I use these for SEPA testing?▾
For client-side and unit-test purposes, yes. For end-to-end transaction tests, use sandbox IBANs from your payment provider.
