# IBAN formats by country

Source: https://veriport.io/iban-format (published 2026-10-28)

Every country that uses the IBAN sets its own length and the structure of its national part (the BBAN); the SWIFT registry publishes both, and the API checks them before the mod-97 digits. 88 countries, 41 in SEPA; each has its own page with the structure and a synthetic example.
