Got a call from 738? Here's what it means.

The three digits after the +1 country code identify the numbering plan area a number was issued in. For 738, that area is California (nearly the entire city of Los Angeles outside of the San Fernando Valley and smaller cities and unincorporated areas of Los Angeles County immediately to the south or east). 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 738 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.
