Area codes 514, 438, and 263 are telephone area codes of the North American Numbering Plan (NANP) for Montreal and most of its on-island suburbs, specifically the Island of Montreal and Île Perrot in the Canadian province of Quebec.
Area code 514 was one of the original North American area codes assigned by AT&T in 1947. The original numbering plan area (NPA) was split twice: in 1957 to create area code 819 and in 1998 to create area code 450. In 2006, the entire remaining 514 area was assigned a second area code, 438, in an overlay plan that made ten-digit dialing mandatory in the Montreal area. Area code 263 was added to the overlay in October 2022.
The incumbent local exchange carrier (ILEC) in the service area is Bell Canada. The major competitive local exchange carriers (CLECs) are Vidéotron, Telus, and Rogers.
