Is a 970 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 970 number can be calling from anywhere.
Robocallers exploit that with "neighbor spoofing": showing a 970 number to people in Colorado because a local-looking call is more likely to be answered. If a 970 call claims to be your bank, the IRS or a delivery company, hang up and call the official number yourself.
About area code 970
970 entered service on April 2, 1995, when it was split from 303.
It is part of the 748/970 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, 748 was carved out of or added to 970.
