Got a call from 310? Here's what it means.
The three digits after the +1 country code identify the numbering plan area a number was issued in. For 310, that area is California (southwestern coastal and coastal-adjacent areas of Los Angeles County, including Beverly Hills, Brentwood, Malibu, Pacific Palisades, Redondo Beach, Santa Monica, Torrance, and Santa Catalina Island). If you don't know anyone there, the call is more likely to be a business, a call centre or an automated dialer than a personal contact.
An area code alone can't tell you who is calling. Numbers are portable, and VoIP providers can issue a 310 number to a caller located anywhere in the world — a technique known as neighbour spoofing, where a familiar area code is used to make a call look local.
To identify the caller, run the full 10-digit number through a lookup. WhoCallsMe checks the number against carrier records, business directories and community spam reports, and shows the line type, carrier and reported risk.
