rdf:langString Area codes 416, 647, and 437 are telephone area codes in the North American Numbering Plan (NANP) for the single rate centre of Toronto, Ontario, Canada. Area code 416 is one of the original North American area codes created by the American Telephone and Telegraph Company (AT&T) in 1947. Area codes 647 and 437 are additional area codes for the same numbering plan area (NPA), forming an overlay numbering plan. The incumbent local exchange carrier in the 416/647/437 territory is Bell Canada. Almost all Toronto Bell Canada landlines are in area code 416, with 647 numbers allocated disproportionately to a growing mobile telephone market and to competitive local exchange providers (such as cable and voice-over-IP gateways). Local numbers are portable, with few limited exceptions for specific services such as pocket pagers. The competitive local exchange carriers for 416/647/437 are Rogers, Telus, and some independent companies. Like the 212 and 312 area codes in New York and Chicago respectively, demand for 416 numbers 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 telephone numbers as their local calling area is a superset of that of a suburban number.
