IBAN Validator
Validate an IBAN: country code, expected length, and the mod-97 checksum. Identifies the bank country and shows the IBAN broken into its parts. Browser-only.
How to use the IBAN Validator
Type or paste any IBAN. Spaces are ignored; case is normalized. The validator checks format against the country's expected length and runs the mod-97 checksum (which catches almost any single-digit error).
