To look up a land line phone number, use an online people search tool such as WhitePages.com, and search the name and city of the person or business registered with the number. Reverse look-ups are also available and rely on the person's phone number as the basic search criteria.
A people search tool is useful for users seeking to reconnect with friends and family with whom they have lost touch. People searches are also commonly used by employers as a method of performing background checks on potential employees. Reverse phone number look-ups are used to find out who may have called from a phone number or to ensure the number being used is correct. Most basic people searches, such as phone number look-ups and reverse phone number searches, are free. More complex services that can provide more information often charge a subscription or per-instance fee.
One such service is Spokeo. Spokeo provides a subscription service that allows a subscriber to search for an individual and obtain information such as the names of relatives, drug charges, assault records, court records, known addresses and the person's birth date. As of March 2015, this service has a seven-day free trial and costs $39.95.
