The Faroe Islands format their IBAN in 18 characters with the BBAN pattern ^[0-9]{14}$: an all-numeric domestic account number split into a 4-digit bank register number and a 10-digit account, identical in shape to the Danish layout.
Breakdown
The official registry example is FO62 6460 0001 6316 34, a SWIFT registry test value rather than a real account:
FO62- country code and IBAN check digits6460- the 4-digit bank register number (reg. nr.) identifying the bank0001631634- the 10-digit account number
The register-number system
Faroese banks are listed in the same combined register that Denmark uses, coordinated through e-nettet, the Danish banks’ shared payment-infrastructure operator, because the Faroe Islands clear through Danish infrastructure. Only a small number of Faroese institutions hold register numbers - the two commercial banks Betri Banki and Føroya Banki alongside the savings banks Norðoya Sparikassi and Suðuroyar Sparikassi - so the 4-digit register number resolves to one of just a few banks. There is no separate branch field, and the Faroese BBAN carries no national check digit, so integrity rests on the IBAN’s MOD-97 check digits alone.
Currency and SEPA context
The Faroe Islands are an autonomous territory of the Kingdom of Denmark but sit outside the European Union, and unlike Denmark they are not part of the SEPA schemes. Everyday payments settle in Danish kroner - the Faroese króna is the same currency as the Danish krone, issued with distinct Faroese banknote designs - so transfers to and from FO IBANs route through standard international correspondent banking on the bank’s BIC rather than over SEPA rails.
Validity remains structural only. An 18-character string that passes the checksum may reference a closed account or an unissued register number, and it says nothing about the holder’s identity. Name-matching services in the style of the EU’s Verification of Payee are the safeguard against paying a well-formed number that belongs to the wrong person.
