Area codes 416, 647, 437, and 942

Area codes 416, 647, 437, and 942 are telephone overlay area codes in the North American Numbering Plan (NANP) for the city of Toronto, Ontario, Canada. Area code 416 was assigned as one of the original North American area codes to a numbering plan area (NPA) in southern Ontario in 1947. After reductions in geographic reach by area code splits in 1953 and 1993, area codes 647, 437, and 942 were added to the remaining service area to provide additional numbering resources. The incumbent local exchange carrier in the NPA is Bell Canada. Almost all Toronto Bell Canada landlines have area code 416, with 647 numbers allocated disproportionately to a growing mobile telephone market and to competitive local exchange carriers, such as cable and voice-over-IP services. Telephone numbers are portable, with few exceptions for specific services such as pocket pagers. The competitive local exchange carriers in the numbering plan area are Rogers Communications, Telus, and some independent companies. Demand for telephone numbers with area code 416 for mobile, foreign exchange and voice over IP service in the 905-suburbs (Durham, Peel, York and Halton regions) has elevated the local significance of these numbers as their local calling area is a superset of that of a suburban number.
