Faroe Islands IBAN validator

A Faroe Islands IBAN is 18 characters, entirely numeric: “FO”, two check digits, a 4-digit bank code, a 9-digit account number, and then one more digit — a national check digit built into the account block itself, on top of the two IBAN-level check digits at the front. That’s a detail worth knowing if you’re used to Denmark’s own IBAN format, which the Faroese format otherwise closely resembles: Danish IBANs run the same 18 characters with a 4-digit bank code, but end in a plain 10-digit account number with no separate check digit tacked on. The Faroe Islands are a self-governing nation within the Kingdom of Denmark, sharing the Danish krone, but they sit outside the EU — and therefore outside SEPA — having never joined when Denmark did, so a Faroese IBAN identifies an account that won’t route through SEPA’s euro-only transfer rails even though it shares a central bank and currency with an EU member.

How this validator works

This tool checks the “FO” prefix, confirms all 16 remaining characters are digits split into a 4-digit bank code and a 10-digit account block (9 digits plus the trailing national check digit), then runs the mod-97 checksum (ISO 7064) — entirely in your browser, nothing sent to a server.

What a pass doesn’t tell you

A pass confirms the 18 digits are correctly structured and internally consistent — not that the account is open or belongs to whoever you expect. This tool does no lookup against Danmarks Nationalbank or any Faroese bank. If a Faroese IBAN fails, recheck the last digit of the account block first — it’s a dedicated national check digit and one of the more common places a single mistyped digit shows up.

Scope: Faroe Islands IBAN structure and mod-97 checksum validation only — not payment processing or confirmation an account is active. Use it to catch a typo before a transfer fails.
