About area code 647
Area code 647 is a Canadian numbering plan area covering City of Toronto (overlay of 416). It was placed into service in 2001 as a overlay code, and today operates under the Eastern Time (EST/EDT, UTC-5/-4) time zone.
Numbers in the 647 NPA are issued in central office (CO) blocks of 10,000 to local exchange carriers, who then assign them to subscribers. Because Canada uses a competitive carrier model under CRTC oversight, multiple carriers — both incumbent and competitive — hold blocks within 647. The current carrier of record for any specific number can be looked up via the Canadian Local Number Portability Consortium, but the originally issued carrier is no longer a reliable signal of who actually serves that line.
If you receive a call from a number beginning with 647, the caller is either physically located in or has historically been associated with City of Toronto (overlay of 416). The same applies to overlay codes 416, 437: any of these area codes can correspond to a phone in the same geography, and many households carry numbers from two or three different overlays simultaneously across landlines and mobile devices.
To call a number in 647 from outside Canada and the United States, dial your country's international access prefix, then +1 647 followed by the 7-digit local number. Within the NANP, simply dial 1 followed by all 10 digits — or just the 10 digits if you are also located in an overlay region where 7-digit local dialling is no longer permitted.
