Users can find the owner of a phone number by doing a reverse phone number search on websites like WhitePages.com and 411.com. Entering a phone number into the search bar of social media websites such as Facebook may yield results if the individual or organization has the phone number listed.
411 and WhitePages each provide a list of names associated with a phone number in addition to the names and numbers of neighbors and people the owner may know, such as relatives. These services also display the registered location of the phone number on a map with the option to retrieve directions to that location. Both the 411 and WhitePages reverse phone number searches are free services.
