About Test IBAN Generator

Synthesize IBANs with valid ISO 13616 checksums per country. Part of the DevTools Surf developer suite. Browse more tools in the Generators collection.

Use Cases

• Fintech developers testing cross-border payment forms
• QA engineers validating IBAN format parsers per country
• Banking app teams seeding test accounts with valid checksums
• Compliance testers verifying SEPA transaction routing logic

Tips

• Select specific countries for region-accurate test IBANs
• Generated checksums follow ISO 13616 mod-97 validation
• Use these IBANs to test payment form validation logic

Fun Facts

• IBAN was first introduced in 1997 by the European Committee for Banking Standards (ECBS) and later adopted as ISO 13616; today over 80 countries use it.
• The longest IBANs belong to Jordan and Malta at 30 characters, while Norway has the shortest at just 15 characters.
• The check digit calculation uses modular arithmetic (mod 97) — the same algorithm can validate an IBAN in a single division operation with 100% reliability.

FAQ

Are the IBANs real?

No — random digits with a valid ISO 13616 checksum. They pass format validation and won't collide with real accounts. Safe for testing payment flows.

Which countries are supported?

40+ SEPA and non-SEPA countries. Each has its own length (UK 22 chars, Germany 22, France 27, Norway 15, etc.) and structure.

Will they pass SEPA validation?

Format validation yes. Routing validation no — the bank codes are random, not real BIC-mapped. Don't use for actual transfer testing.

Can I generate many at once?

Bulk mode: 1–1000 at a time. Output as plain list, CSV, or SQL inserts. Useful for seeding bank-account fields.
