How to use these IBAN format guides

Each country page lists the expected IBAN length, two-letter country code, print format example, and digital format example. Use the pages to understand structure before validating an actual value locally in the IBAN Checker.

Format validation only

BankCodeKit validates country support, length, allowed characters, and checksum. It does not confirm that an account exists, belongs to a payee, or can receive a payment.
