Every country in the ISO 13616 IBAN registry with its country code, SEPA membership, IBAN length, and a sample IBAN you can send to the IBAN Validation API while you test. Account check marks countries where the national account number has its own check digit that our validation verifies; Branch marks IBANs that carry a branch code as well as a bank code. For IBANs with a known expected result see test IBAN numbers.

= yes. 89 countries in the registry, 22 further countries with partial or experimental support below.

Countries in the IBAN registry

Territories that use another country's IBAN code

Accounts in these territories carry the IBAN country code and format of the country listed; the territory's own ISO code, shown in brackets, never appears in the IBAN. SEPA reachability follows the territory, not the IBAN prefix.

Partial IBAN countries (experimental)

These countries use an IBAN-style account number that is not in the official registry. We validate the check digits and length; bank and branch data is limited.
