, which was and still is Canada's largest toll-free calling zone. The Golden Horseshoe's explosive growth in the second half of the 20th century and the corresponding expansion of telecommunications service would have made another area code necessary in any event. However, the timetable was advanced because Canada's system of number allocation does not use

(CLEC) is assigned blocks of 10,000 numbers, which correspond to a single three-digit prefix, for every rate centre in which it plans to offer service. Most rate centres do not need that many numbers, but excess numbers cannot be reassigned elsewhere once they are assigned to a rate centre. The problem was not as severe in the Golden Horseshoe as in the rest of Canada since, numbers have tended to be used up fairly quickly. However, the number allocation system did not allow number blocks to be reassigned from smaller rate centres to the Toronto rate centre. The proliferation of cell phones, pagers, fax machines, and dial-up Internet connections made it obvious that the Golden Horseshoe needed another area code.

Automatic number identification Automatic number identification (ANI) is a feature of a telecommunications network for automatically determining the origination telephone number on toll calls for billing purposes. Automatic number identification was originally created by the Am ...

(ANI) in some central office switching systems in the numbering plan area started operation on October 11, 1992. The new area code entered service on October 11, 1993. Permissive dialing of 416 continued across the Golden Horseshoe until January 1, 1994. However, portions of the 905 territory have remained ever since a local call to Toronto. The creation of area code 905 was intended as a long-term solution. However, five years after its introduction, area code 905 was close to exhaustion far sooner than anticipated, again due to the proliferation of cell phones and pagers. By 1999, the CRTC had established an ad hoc committee to study code relief planning for area code 905. A split of the NPA was considered, with various options being presented: * a geographic split by municipality (either two-way or three-way) * a geographic split of concentric rings around Toronto * a realignment of NPA boundaries * a distributed overlay The overlay option was chosen because it would cause the least disruption and was supported by all of the carriers. A split would have forced customers to change their numbers for the second time in less than a decade and forced the reassignment of cellphone numbers. For the same reason, Toronto was overlaid with area code 647 (and later 437). NPA 289 was approved by the CRTC on August 15, 2000 in Order CRTC 2000–772. The order had the CRTC direct Bell Canada to implement a ten-digit local dialing plan. Permissive seven-digit or ten-digit dialing for 905-customers began on April 7, 2001, before the in-service date for 289 of June 9, 2001. The Golden Horseshoe's continued growth caused area code 365 to be assigned for further relief on March 25, 2013. Also, area code 742 was assigned on October 16, 2021. A numbering plan exhaust analysis of 2020 projected an exhaust date of March 2023 for the numbering plan area. Area code 537 was reserved as a fifth area code for the region in November 2022.
