History

Area code 514 served the entire

area for over half-a-century. However, by the mid-1990s, it was on the verge of exhaustion because of Montreal's rapid growth and Canada's inefficient system of number allocation. All competitive local exchange carriers in Canada are allocated blocks of 10,000 numbers for every rate centre in which they plan to offer service, even in the smallest hamlets. Even though most rate centres do not need nearly that many numbers, a number cannot be reallocated elsewhere once it is assigned to a carrier and rate centre. That resulted in thousands of wasted numbers. By the late 20th century, that made a second area code necessary in Canada's second-largest toll-free calling zone. Area code 450 entered service in 1998. The numbering plan area completely surrounds area code 514, which was confined to the

). For that reason, Montrealers sometimes refer to the off-island suburbs as "les 450" (the 450s), much like the suburbs of Toronto are called " the 905." On May 7, 2009, the CRTC ruled that area code 438, which had been used as an overlay for area code 514 since 2006, would be extended to overlay area codes 450 and 514. However, a later decision changed that to overlay only area code 450 with the new area code 579, effective August 21, 2010. On May 2, 2011, a prepaid
