Is a 639 call a scam?
An area code tells you where a number was first assigned, not where the caller is. Mobile numbers keep their area code when people move, and internet (VoIP) numbers can be picked in any area code — so a 639 number can be calling from anywhere.
Robocallers exploit that with "neighbor spoofing": showing a 639 number to people in Saskatchewan because a local-looking call is more likely to be answered. If a 639 call claims to be your bank, the IRS or the CRA or a delivery company, hang up and call the official number yourself.
About area code 639
639 entered service on May 25, 2013, as an overlay on 306, which had run short of numbers.
It is part of the 306/474/639 overlay: the codes cover the same area, and a new line there can be given a number in any of them. Two neighbours — or two phones in one household — can have different area codes. That is also why local calls need the full ten digits.
As the region grew, 474 was carved out of or added to 639.
Because 639 overlays the same ground, the cities listed are those of the codes it shares with.
