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.

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.
