Area code 514 is a telephone area code for Montreal and most of its surrounding area. It covers Montreal Island, Île Perrot, and Île Bizard in the province of Quebec. Area code 514 was one of the 86 original North American Numbering Plan Areas defined in 1947. It originally covered the western half of the province, including several areas in the far northern portion of the province without telephone service. However, in 1957, it was reduced to the region surrounding Montreal in a three-way split. Area code 819 was created out of the western half of the original 514 territory, while the far northern portion was added to area code 418. The final boundary change occurred in 1998 when the off-island suburbs became area code 450, which now completely surrounds 514. It was overlaid with area code 438 beginning on November 4, 2006, as part of the change to mandatory ten-digit dialing, according to the North American Numbering Plan Administration (NANPA).
Area code 438 was considered for overlaying 450 as well, but a later decision determined that 579 would be the overlay code for that area.
