Is a 540 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 540 number can be calling from anywhere.
Robocallers exploit that with "neighbor spoofing": showing a 540 number to people in Virginia because a local-looking call is more likely to be answered. If a 540 call claims to be your bank, the IRS or a delivery company, hang up and call the official number yourself.
About area code 540
540 entered service on July 15, 1995, when it was split from 703.
It is part of the 540/826 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, 276 and 826 were carved out of or added to 540.
