Postal codes in Greenland
Postal codes in Greenland consist of the two letter ISO 3166 code "GL", followed by four digits, the first two of which are "39".
They were first introduced in 1967 as part of the Danish postcode system, which also originally included the Faroe Islands.
Previously, the capital of Greenland, Nuuk, was known by the Danish language name Godthåb, and the "DK" prefix for Denmark was used with the postcode in addresses.
In addition, "DK-3900 Nuuk" is also used.
