Area codes 514 and 438

The numbering plan area was split twice: in 1957 to create area code 819, and in 1998 to create area code 450.

514 originally covered the entire western half of Quebec from the US border to Hudson Strait, while 418 served the eastern half.

Area codes 450 and 579 are telephone area codes in the North American Numbering Plan for the Canadian province of Quebec, encompassing the off-island suburbs of Montreal, which is served by area codes 514 and 438.

The area codes are assigned in an overlay plan to a territory that includes the Island of Montreal, Île Perrot, and Île Bizard in the province of Quebec.

Those are some of the reasons that the numbering plan areas corresponding to four of the five largest Canadian markets (416 in Toronto, 514 in Montreal, 604 in Vancouver, and 403 in Calgary) were split in the 1990s.

Quebec was split between area codes 514 and 418.

Nominally, northwestern Quebec—one of the few areas of North America without telephone service—was reassigned from area code 514 to 418 in 1957.

The initial area codes were created in 1947 as routing codes for operator-assisted calls.

A few western on-island suburbs (the "West Island") were never combined into the main Montreal rate centre and therefore have a reduced subset of the Montreal local calling area.

These arbitrary boundaries do not necessarily correspond in any way to the original boroughs, the "une île, une ville" municipal amalgamation or the subsequent de-fusion of areas like Westmount.

Area code 514 was one of the 86 original numbering plan areas (NPAs) defined by AT&T in 1947.

In November 2006, the entire remaining numbering plan area 514 was assigned a second area code, 438, making ten-digit dialing mandatory in the Montreal area.

The incumbent local exchange carrier (ILEC) in the service area is Bell Canada.

The major competitive local exchange carriers (CLEC's) are Vidéotron, Telus, Rogers.
