Area Code 647 History:
03/05/2001
Area code 647 was officially put into service. Area code 647 is an overlay of area code 416. On March 25, 2013 area codes 416 and 647 were overlaid with area code 437.
The Canadian Radio-television and Telecommunications Commission (CRTC) has approved area code 942 as a distributed overlay covering existing area codes 416, 437, 647 effective 04/26/2025.
Ten digit dialing (area code + seven digit number) is necessary in the 416/647/437 overlay because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
