IBAN Generator
Generate checksum-valid fake IBANs for testing, not real accounts.
About this tool
These are fake IBANs for software testing only — they don't correspond to real bank accounts. Generate correctly-formatted, checksum-valid IBANs (structurally valid per the ISO 7064 mod-97 check used by real IBANs) for testing payment forms or validation logic, matching the exact length and check-digit rules of the country you pick.
The account number portion is randomly generated — it isn't a real bank's account numbering scheme, just a structurally valid placeholder. Everything runs locally in your browser.
Frequently asked questions
- Will these IBANs work for a real bank transfer?
- No. They pass the same checksum real IBANs use (so they'll pass basic format validation), but the account number is random and not tied to any real bank or account — any real payment system will reject them.
- What's the mod-97 checksum?
- The two check digits after the country code are computed so the whole IBAN, rearranged and converted to a big number, leaves a remainder of exactly 1 when divided by 97 — the same check this site's IBAN Validator tool verifies.
- Is my data uploaded anywhere?
- No — every IBAN is generated entirely in your browser.
