Is a 530 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 530 number can be calling from anywhere.
Robocallers exploit that with "neighbor spoofing": showing a 530 number to people in California because a local-looking call is more likely to be answered. If a 530 call claims to be your bank, the IRS or a delivery company, hang up and call the official number yourself.
About area code 530
530 entered service on November 1, 1997, when it was split from 916.
It is part of the 530/837 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, 837 was carved out of or added to 530.
