Area code 867 covers Canada's three northern territories: Yukon, Northwest Territories, and Nunavut. Established in 1997 from portions of area codes 403, 819, and 416, it spans the largest geographical area of any North American area code. It includes cities such as Whitehorse, Yellowknife, and Iqaluit. The region is known for its remote communities, Indigenous cultures, and harsh climates. Due to low population density, 867 is not expected to require overlays or splits for the foreseeable future. It serves as a unifying and unique identifier for Canada's vast Arctic region.
