How a Faroe Islands IBAN is structured

A Faroe Islands IBAN is read left to right: a 2-letter ISO 3166 country code (FO), 2 MOD 97 check digits, then a 14-character BBAN. The BBAN is split into 3 fields: 4 digits, 9 digits, 1 digit.

How Faroe Islands IBAN check digits work

The two digits at positions 3–4 are a MOD 97-10 checksum computed from the country code and the BBAN. To verify it, the IBAN is rearranged (BBAN first, country code and check digits last), letters are converted to numbers (A = 10, B = 11, …), and the whole integer is taken mod 97. A valid IBAN has a remainder of 1. This catches any single-digit typo and most transposition errors — which is why a one-character mistake is enough to make a Faroe Islands IBAN fail validation instantly.

Faroe Islands IBAN FAQ

How long is a Faroe Islands IBAN?
A Faroe Islands IBAN is always 18 characters long: 2 letters for the country code (FO), 2 check digits, and a 14-character BBAN. Any Faroe Islands IBAN that is shorter or longer than 18 characters is invalid.
What country code does a Faroe Islands IBAN start with?
A Faroe Islands IBAN starts with the ISO 3166 country code FO. The first two characters are always FO, followed by two MOD 97 check digits, then the country-specific BBAN.
How do I validate a Faroe Islands IBAN?
Paste the IBAN into the validator on this page — it checks the character set, the 18-character length, and the MOD 97 check digits, all in your browser. You can also open the full IBAN validator with a Faroe Islands example pre-filled.
Does a valid Faroe Islands IBAN mean the account exists?
No. Validation only confirms the IBAN is structurally well-formed and the check digits are correct per ISO 13616. It does not verify the account exists, is open, or belongs to anyone. Always confirm with the recipient or their bank before sending money.
