Dialling from and to North York
Because North York sits inside an overlay region with 3 overlapping area codes, callers must always dial 10 digits — even for calls between two phones on the same street. From outside Canada and the United States, dial your international access prefix, then +1, then the 10-digit number.
Mobile carriers in North York typically issue numbers from whichever overlay code is currently being released by the NANP relief plan. As a result, two members of the same household frequently carry numbers from two different area codes — for example a long-time resident with an original-assignment number and a newer subscriber with an overlay number.

About North York, Ontario
North York is located in Ontario, Canada. It is one of the cities catalogued by AreaTrace within this province. The city falls within the Eastern Time (EST/EDT, UTC-5/-4) time zone.
Numbers issued to subscribers in North York can come from any of the area codes assigned to the surrounding numbering plan area: 416, 647, 437. With number portability now standard across all Canadian carriers, the area code attached to a North York number tells you only where that number was first issued — not who currently carries it or where the device is physically located.
If you are trying to identify a recent call from 416 or 647 or 437, the caller is most likely either based in North York or another community within the same NPA, has previously held a number issued in this area, or — in the case of telemarketing and scam calls — is spoofing a local prefix to increase the chance you pick up.
