Falkland Islands IBAN validator

A Falkland Islands IBAN is 18 characters: “FK”, two check digits, a 2-letter bank code, and a 12-digit account number. That 2-letter bank code stands out against most letter-based IBAN bank codes, which typically run 4 letters — Gibraltar’s and the British Virgin Islands’ both use 4, for instance — making the Falkland Islands’ compact 2-letter identifier one of the shortest letter-based bank codes covered on this site. The Falkland Islands are a British Overseas Territory in the South Atlantic with their own currency, the Falkland Islands pound, fixed 1:1 to the pound sterling and regulated locally by the Falkland Islands Financial Services Commission rather than the Bank of England directly. At only 18 characters total, a Falkland Islands IBAN also sits among the shorter formats in the registry, despite mixing letters and digits rather than running purely numeric the way similarly short formats like Denmark’s do.

How this validator works

This tool checks the “FK” prefix, confirms the bank code is exactly 2 letters, and confirms the account number is exactly 12 digits, then runs the mod-97 checksum (ISO 7064) a correctly generated Falkland Islands IBAN must satisfy — entirely in your browser, with nothing sent to a server.

What a pass doesn’t tell you

A pass confirms the 18 characters are correctly structured and internally consistent — not that the account is open, active, or belongs to whoever you expect. This tool does no lookup against the Falkland Islands Financial Services Commission or any bank there. If a Falkland Islands IBAN fails, double-check the 2-letter bank code first — being shorter than most, a single wrong letter there throws off the whole checksum with less room to notice visually.

Scope: Falkland Islands IBAN structure and mod-97 checksum validation only — not payment processing or confirmation an account is active. Catch the typo here; confirm the account with the bank.
