Dialling from and to Sault Ste. Marie
Because Sault Ste. Marie 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 Sault Ste. Marie 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.

Numbers issued to subscribers in Sault Ste. Marie can come from any of the area codes assigned to the surrounding numbering plan area: 705, 249, 683. With number portability now standard across all Canadian carriers, the area code attached to a Sault Ste. Marie 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 705 or 249 or 683, the caller is most likely either based in Sault Ste. Marie 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.
