Area Code 86 – Sisimiut

Overview of Greenland's +299 86 Geographic Prefix

The +299 86 prefix is a geographic National Destination Code (NDC) within the Greenlandic national numbering plan, as defined under ITU-T E.164. It is specifically allocated to the town of Sisimiut, the second-largest urban center in Greenland, located on the western coast approximately 320 km north of the capital, Nuuk. Sisimiut serves as a key administrative, commercial, and educational hub for the Qeqqata Municipality, and the 86 prefix is used for fixed-line PSTN services within this region.

Dialing Formats and Usage

When calling a Sisimiut fixed-line number from abroad, the international format is +299 86 XX XXX, where +299 is the country calling code for Greenland, 86 is the geographic area code, and the remaining six digits constitute the local subscriber number. From within Greenland, callers must dial the national format 86 XX XXX (without the leading +299). It is important to note that Greenland uses a closed numbering plan; therefore, no trunk prefix (such as '0') is required for domestic calls. The total number length, including the country code, is 11 digits.

Geographic Coverage and Administrative Jurisdiction

The 86 prefix is exclusively assigned to the Sisimiut exchange area, which encompasses the town itself and its immediate surroundings. Sisimiut is the capital of the Qeqqata Municipality and is known for its fishing industry, tourism, and as a gateway to the Arctic Circle Trail. The prefix does not cover other towns in the municipality, such as Kangerlussuaq (which uses a different code), ensuring that callers can reliably identify the geographic origin of a fixed-line number.

Caller Instructions and Overlay Considerations

For local callers within Sisimiut, dialing the full national number (86 XX XXX) is always required, as there are no local abbreviated dialing procedures for standard PSTN calls. For international callers, the plus sign (+) is recommended for mobile users, while landline users should use their country's International Direct Dialing (IDD) prefix (e.g., 011 from North America, 00 from most European countries) followed by 299 and the subscriber number. Currently, there are no overlay codes in Sisimiut; the 86 prefix is unique to this region, and number portability is not widely implemented for fixed lines in Greenland.

Practical Examples

• International call: +299 86 12 345
• Domestic call (within Greenland): 86 12 345

Understanding the geographic significance of the 86 prefix is essential for businesses and individuals maintaining regular contact with Sisimiut, as it ensures correct call routing and billing.
