Area codes 514 and 438 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 state of Quebec. Area code 514 was one of the original area codes assigned by AT & T in 1947. The original count 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 and then ten-digit dial became compulsory in the Montreal area. 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.

history [edit ]
Bell exchange, Montreal, late 1890s Montreal ‘s local calls were primitively handled manually by operators. A called party was requested by name before the first ( four-digit ) local numbers were assigned in July 1881. In 1898, substitution names ( “ Main, ” “ Westmount, ” “ Uptown, ” and “ East ” ) were added before the count. The initial rotary dial exchange, “ lancaster, ” was deployed April 25, 1925. [ 1 ] [ failed verification ] Subscribers dialled two letters of an substitute diagnose and four digits ( 2L+4N ) and therefore “ lancaster 1234 ” became LA-1234 ( or 52-1234 ). [ 2 ]
The initial area codes were created in 1947 as routing codes for operator-assisted calls. Quebec and Ontario were the only provinces that received multiple area codes. Quebec was split between sphere codes 514 and 418. Area code 514 was in the first place assigned to the integral western half of Quebec from the Canada–US frame to the Hudson Strait. The sphere nominally included several remote control areas in the far northerly share of the state that at the time did not have telephone service. When the Bell System implemented direct distance dial ( DDD ) for content-wide serve using a seven-digit local telephone act, prefixed by a three-digit area code, Montreal and Toronto, the largest canadian cities, still used six-digit ( 2L-4N ) number plans. between 1951 and 1958, telephone numbers were lengthened by adding one digit ( 3L-4N ) to be compatible. [ 3 ] Numbering plan area code 514 was split in 1957 to create area code 819 for most of western Quebec, from Estrie ( Sherbrooke ) to the Ontario molding, with the unserved far northern dowry nominally added to 418 ( and later moved to 819 ). Area code 514 was reduced to the area surrounding Montreal. That shape remained unchanged for 41 years. In 1998, the off-island suburbs ( Laval, Montérégie, etc. ) received area code 450, which nowadays wholly surrounds 514. That left 514 as the Island of Montreal and a few surrounding smaller islands, which makes it one of the six pairs of doughnut area codes in the number plan and one of two in Canada, the other being Toronto ‘s area code 416. The 1998 rip was intended as a long-run solution to a dearth of available numbers in Canada ‘s second-largest toll-free calling zone. however, within less than a ten, 514 was close to exhaustion because of the proliferation of calculator, beeper, and cell earphone technologies. The problem was exacerbated by Canada ‘s ineffective system of number allocation. Unlike the United States, Canada does not use act pool as a easing measurement. Every competing carrier wave is assigned blocks of 10,000 call numbers, which correspond to a single cardinal office prefix, in every rate center in which it plans to offer service. Once a telephone number is allocated to a mailman and rate centre, it can not be reused elsewhere, even when a rate center has more than enough numbers to serve it. That resulted in thousands of bony call numbers. many larger cities have multiple pace centres, which have never been amalgamated. Montreal is an exception since it is Canada ‘s second-largest pace centre.

The number allotment problem was not as hard in Montreal as in other areas of Canada since numbers tend to be used up reasonably cursorily. however, numbers from the suburban areas to Montreal could not be reassigned, and it became apparent that the area needed another area code. On November 4, 2006, numbering design area 514 was overlaid with area code 438, which required ten-digit dial for all subscribers in the Montreal area, even for local calls. By then, overlays had become the favored relief measure in Canada, as they affect existing subscribers the least and provide a workaround for the number allocation trouble. No area codes have been split in Canada since 1999. The number allotment problem is still unaddressed, but under current projections, Montreal will not need another area code until 2023. [ 4 ] Despite Montreal ‘s proceed growth, 514/438 is nowhere near exhaustion. Area code 438 was considered for overlaying 450 angstrom well, but a by and by decision determined rather that 579 would be the sheathing code. [ 5 ] As of February 2017, area code 263 is reserved for a third base sphere code in the region. [ 6 ]
Service area [edit ]
A few western Montreal neighbourhoods were never combined into the independent Montreal rate center and therefore have a reduced subset of the Montreal local calling area .
due to Canada ‘s issue allotment system, when a CLEC reserves one prefix for each of the island ‘s six rate centres ( including Montreal ), it has the effect of reserving 60,000 numbers before enrolling its first subscriber .
