open-in-new
<p>Area codes 416, 647, 437, and 942 are telephone <a href="/facts/Overlay_complex/faRNxFIj">overlay</a> <a href="/facts/Area_code/jaryReDv">area codes</a> in the <a href="/facts/North_American_Numbering_Plan/0QQ8v3ph">North American Numbering Plan</a> (NANP) for the city of <a href="/facts/Toronto/cnXH7881">Toronto</a>, Ontario, Canada. </p><p>Area code 416 was assigned as one of the <a href="/facts/Original_North_American_area_codes/EWUcPcBz">original North American area codes</a> to a <a href="/facts/Numbering_plan_area/0QQ8v3ph">numbering plan area</a> (NPA) in southern Ontario in 1947. After reductions in geographic reach by <a href="/facts/Area_code_split/naIyV2S2">area code splits</a> in 1953 and 1993, area codes 647, 437, and 942 were added to the remaining service area to provide additional numbering resources. </p><p>The <a href="/facts/Incumbent_local_exchange_carrier/Rjprpgt7">incumbent local exchange carrier</a> in the NPA is <a href="/facts/Bell_Canada/k3hgDpJA">Bell Canada</a>. Almost all Toronto Bell Canada landlines have area code 416, with 647-numbers allocated disproportionately to a growing <a href="/facts/Mobile_phone/H3EcqD9h">mobile telephone</a> market and to <a href="/facts/Competitive_local_exchange_carrier/tzF93Bcj">competitive local exchange carriers</a>, such as cable and voice-over-IP services. Telephone numbers <a href="/facts/Local_number_portability/NFJQeJpr">are portable</a>, with few exceptions for specific services such as pocket <a href="/facts/Pager/aBeT40yG">pagers</a>. The <a href="/facts/Competitive_local_exchange_carrier/tzF93Bcj">competitive local exchange carriers</a> in the numbering plan area are <a href="/facts/Rogers_Communications/PA4xn7Gu">Rogers Communications</a>, <a href="/facts/Telus/h58eorGP">Telus</a>, and some independent companies. </p><p>Demand for telephone numbers with area code 416 for mobile, <a href="/facts/Foreign_exchange_service_(telecommunications)/wFqjrzNy">foreign exchange</a> and <a href="/facts/Voice_over_IP/5QGBbXYg">voice over IP</a> service in the <a href="/facts/Area_codes_905%2c_289%2c_and_365/uRNpqjBv">905-suburbs</a> (<a href="/facts/Regional_Municipality_of_Durham/VMTk0Myq">Durham</a>, <a href="/facts/Regional_Municipality_of_Peel/4ytD3aso">Peel</a>, <a href="/facts/Regional_Municipality_of_York/0g5rlfjE">York</a> and <a href="/facts/Regional_Municipality_of_Halton/f45pd5k7">Halton</a> regions) has elevated the local significance of these numbers as their local calling area is a superset of that of a suburban number. </p>
