Got a call from 650? Here's what it means.
The three digits after the +1 country code identify the numbering plan area a number was issued in. For 650, that area is California (Daly City, South San Francisco, Palo Alto, Redwood City, Menlo Park, Mountain View, San Mateo, Santa Clara). 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 650 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.
