Area Code 416

Area code 416 is one of the original 86 telephone area codes of North America from 1947, and currently serves the single rate centre of Toronto, Ontario, Canada. It has been split twice: the western portion of 416 became area code 519 in 1953, and in 1993 the remaining portion of 416 outside of Metropolitan Toronto (now Toronto) became 905.

In 2001, 416 was overlaid with area code 647, Canada's first overlay code. All calls were required to be dialed with ten digits since the introduction of the overlay. A geographic split was not feasible because of the high population density and lack of a well-defined boundary along which to split. The success of the overlay made it standard in Canada for future relief, even in large rural areas.

Along with the neighbouring 905, 416 officially became ''exhausted'' in November 2005. As a result, all new central office prefixes will be assigned in NPA 647, as there are no longer any available prefixes in 416. At the current rate of growth, a third area code is expected to be required sometime around 2014.

The incumbent local exchange carrier in the 416 and 647 area codes is Bell Canada; the last independent company in the previous 416 area code region was acquired by Bell Canada around the year 1980.
