Area codes 418, 581, and 367

Area codes 418, 581, and 367 are telephone area codes in the North American Numbering Plan for the Canadian province of Quebec, encompassing the eastern portion of the province. The three codes are assigned the same Canadian territory in an overlay plan, including Quebec City, Saguenay–Lac-Saint-Jean, Rivière-du-Loup, Rimouski and the Gaspé Peninsula, Côte-Nord and southeastern Mauricie regions, but 418 also serves the tiny hamlet of Estcourt Station, in the U.S. state of Maine.


Area code 418 was one of the original area codes created by AT&T in 1947. Then, as now, its boundaries generally follow those of the eastern half of Quebec.

Nominally, northwestern Quebec—one of the few areas of North America without telephone service—was reassigned from area code 514 to 418 in 1957. From the 1950s to the 1970s, 418 was also the area code for the eastern Northwest Territories. However, in the 1970s, as direct distance dialling was introduced to the far northern and western portions of 418, these points were reassigned to area code 819.

In 2008, area code 581 was implemented as an overlay when 418 came close to exhaustion.[1]

In 2018, area code 367 was implemented as 418 and 581 came close to exhaustion.[2]

The major incumbent local exchange carriers in the area are Bell Canada, Bell Aliant, Telus (formerly Quebec-Telephone) and Vidéotron.
