Is a 539 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 539 number can be calling from anywhere.
Robocallers exploit that with "neighbor spoofing": showing a 539 number to people in Oklahoma because a local-looking call is more likely to be answered. If a 539 call claims to be your bank, the IRS or a delivery company, hang up and call the official number yourself.
About area code 539
539 entered service on April 1, 2011, as an overlay on 918, which had run short of numbers.
It is part of the 539/918 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.
Because 539 overlays the same ground, the cities listed are those of the codes it shares with.
