California Reverse Phone Lookup

Reverse Phone Lookup by California Area Code

Twenty-plus area codes blanket California, from 213/323 in LA to 415/628 in San Francisco, 619/858 in San Diego, and beyond. The sheer number of overlays means area codes have lost most of their meaning. Browse the table below to see all codes and cities, then search the number for the owner 's name and location.

Important: Area codes do not guarantee the caller's current location. California allows number portability, and scammers often use "neighbor spoofing" to make calls appear local.
