Area Code 31 – Nuuk

Geographic Overview

The area code +299 31 is a geographic National Destination Code (NDC) assigned to the capital city of Nuuk, the administrative and economic center of Greenland. As part of the Greenlandic numbering plan, which follows ITU-T E.164, this code routes calls to fixed-line subscribers within the Nuuk area. Greenland's telecommunication infrastructure is managed by Tusass A/S (formerly TELE Greenland), the incumbent operator, and the country uses the country calling code +299.

Dialing Formats and Usage

When calling a fixed-line number in Nuuk from abroad, the international format is +299 31 XX XX, where the full national significant number (NSN) is eight digits, including the two-digit area code. From within Greenland, callers must dial the eight-digit national number directly, omitting the international prefix and country code: 31 XX XX. For example, a local Nuuk number might be 31 45 67; internationally, it would be dialed as +299 31 45 67.

Nuuk is the largest city in Greenland, with a population of approximately 19,000, and serves as the primary hub for government, commerce, and education. The area code covers the entire municipality of Sermersooq, which includes the capital and surrounding settlements such as Kapisillit and Qeqertarsuatsiaat. However, the code is specifically associated with the urban center of Nuuk, where most fixed-line services are concentrated.

Technical Considerations

Geographic codes in Greenland are used for traditional PSTN (Public Switched Telephone Network) services, but they may also be used for VoIP (Voice over Internet Protocol) services that are tied to a physical location. Callers should note that the cost of calling a Nuuk number depends on the caller's location and the terms of their telecom provider. For international callers, the prefix +299 is required, followed by the area code and subscriber number. No trunk prefix (such as '0') is used in Greenland; the national number is dialed in its entirety.

As with many small jurisdictions, number portability is available, meaning that a subscriber may retain their number when switching providers, but the geographic association remains with the original area code. For emergency services, callers in Nuuk should dial 112, regardless of the area code.

In summary, +299 31 is the geographic code for Nuuk, Greenland, essential for reaching fixed-line subscribers in the capital. Understanding the correct dialing format ensures seamless connectivity for both local and international callers.
