Greenlandic IBAN format (GL) — length, structure, example

Greenland formats its 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 GL89 6471 0001 0002 06, a SWIFT registry test value rather than a real account:

• GL89 - country code and IBAN check digits
• 6471 - the 4-digit bank register number (reg. nr.) identifying the bank
• 0001000206 - the 10-digit account number

The register-number system

Greenlandic banks are listed in the same combined register that Denmark uses, coordinated through e-nettet, the Danish banks’ shared payment-infrastructure operator, because Greenland clears through Danish infrastructure. Only two banks operate in Greenland - Grønlandsbanken, the Bank of Greenland, and one other institution that holds several further register numbers - so the 4-digit register number resolves to one of just two banks. There is no separate branch field, and the Greenlandic BBAN carries no national check digit, so integrity rests on the IBAN’s MOD-97 check digits alone.

Currency and SEPA context

Greenland is an autonomous territory of the Kingdom of Denmark but sits outside the European Union, having withdrawn from the European Communities in 1985, and unlike Denmark it is not part of the SEPA schemes. Everyday payments settle in Danish kroner, the currency Greenland shares with the rest of the realm, so transfers to and from GL 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.
