Greenland IBAN validator

A Greenlandic IBAN is 18 characters, entirely numeric: “GL”, two check digits, a 4-digit bank code, and a 10-digit account number — a layout that matches Denmark’s own IBAN structure digit for digit, since Greenland’s banking system runs on the same Danish krone and the same 4-and-10 split as Denmark proper. That’s actually the more notable design detail here: unlike the Faroe Islands, which use the same 18-character length but tuck a separate national check digit into the end of their account block, Greenland’s 10 digits form a plain account number with no extra check digit layered in. Greenland is an autonomous territory within the Kingdom of Denmark that left the European Economic Community in 1985 — years after Denmark itself joined — and remains outside the EU today, so a Greenlandic IBAN, like a Faroese one, identifies an account that doesn’t route through SEPA’s euro transfer network despite the shared currency and central bank.

How this validator works

This tool checks the “GL” prefix, confirms the bank code is exactly 4 digits and the account number is exactly 10 digits, then runs the mod-97 checksum (ISO 7064) a correctly generated Greenlandic IBAN must satisfy — entirely client-side, with 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 performs no lookup against Danmarks Nationalbank or any Greenlandic bank. If a Greenlandic IBAN fails, work through the 4-digit bank code and 10-digit account number as two separate blocks rather than one long string — it’s easier to spot a transposed digit that way.

Scope: Greenlandic 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.
