Is a 438 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 438 number can be calling from anywhere.
Robocallers exploit that with "neighbor spoofing": showing a 438 number to people in Quebec because a local-looking call is more likely to be answered. If a 438 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 438
438 entered service on November 4, 2006, as an overlay on 514, which had run short of numbers.
It is part of the 263/438/514 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.
