A reverse phone lookup is a method for identifying the owner of a specific phone. It's possible to get the details of the number owner's name and address through free reverse phone directories, as well as paid services, available on the Internet.
Information for both business and residential landline numbers can be obtained through reverse lookup, which is a free function of search engines, such as Google, Bing and Yahoo!. It works by typing the full 10-digit number, separated by hyphens, into the search field and pressing the enter key. The search engine returns a listing of all results. If the number is listed, the results include the number owner's name and street address, as well as a map link to the location. Numbers that are unpublished or unlisted may not produce any information in the results.
Additionally, by performing a search for reverse phone lookup, a listing of sites that provide the service generate. By using these sites, there may be additional information or advanced search functionality offered for a fee.
As of February 2015, the reverse lookup function is free to use for looking up landlines and business numbers, but it's not free to look up cell phone numbers. Service providers, rather than phone companies, issue numbers for cell phones, making the information harder to obtain. With the exception of the additional fee, the services work in the same manner for reverse cell phone lookup.
