Canadian area code assignments are managed by the Canadian Numbering Administrator (CNA) under the broader North American Numbering Plan (NANP). As Northwest Territories's population and demand for phone numbers grew — driven by cell phones, VoIP lines, and pagers — regulators either split existing area codes or added overlay codes that share territory with the original.
Northwest Territories observes the Mountain time zone. Most of Canada observes Daylight Saving Time from the second Sunday in March through the first Sunday in November, except parts of Saskatchewan which stays on Central Standard Time year-round.
When you receive a call from a Northwest Territories number, the area code tells you only where the number was originally assigned. Because of Local Number Portability (LNP), Canadian callers can keep their phone numbers when moving across provincial lines — so a 867 number is no longer a guarantee the caller is physically in Northwest Territories.
Phone number format in Northwest Territories
All Northwest Territories phone numbers follow the standard 10-digit NANP format: (NPA) NXX-XXXX. For local calls within Northwest Territories, 10-digit dialing is mandatory because of overlay codes. For long-distance calls within Canada or to the US, dial 1 + area code + 7-digit number. From outside North America, dial your international access prefix, then 1 (the NANP country code), then the 10-digit number.
