POST Greenland, operating under the brand Tusass, manages all postal and telecommunications services across this autonomous territory. The Greenlandic postcode system is integrated with the Danish postal system but utilizes a specific four-digit range to cover its vast, sparsely populated regions. Given the unique geography, these codes are vital for coordinating air and sea mail distribution to remote coastal settlements.
Greenland uses a four-digit numeric postcode system. All Greenlandic codes reside within the 3900-3999 range, where 3900 is assigned to the capital and subsequent numbers represent other towns and settlements.
