Is a 484 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 484 number can be calling from anywhere.
Robocallers exploit that with "neighbor spoofing": showing a 484 number to people in Pennsylvania because a local-looking call is more likely to be answered. If a 484 call claims to be your bank, the IRS or a delivery company, hang up and call the official number yourself.
About area code 484
484 entered service on June 5, 1999, as an overlay on 610, which had run short of numbers.
It is part of the 484/610/835 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, 835 was carved out of or added to 484.
