Between 1951 and 1958, telephone numbers were lengthened by adding one digit (2L-5N) to be compatible. Numbering plan area code 514 was split in 1957 to create

The number allocation problem was not as severe in
Montreal as in other areas of Canada since numbers tend to be used up fairly quickly. 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,

The 1998 split was intended as a long-term solution to a shortage of available numbers in Canada's second-largest toll-free calling zone. However, within less than a decade, 514 was close to exhaustion because of the proliferation of computer, pager, and cell phone technologies. The problem was

The number allocation problem is still unaddressed, but under current projections, Montreal will not need another area code until 2023. Despite
Montreal's continued growth, 514/438 is nowhere near exhaustion.
