Determine the owner of a phone number by using a reverse phone lookup service, such as WhitePages.com, or a subscription service, such as Spokeo. These services search public records databases to return information on individuals with little required input.
WhitePages.com provides a free service that returns the phone number's owner and people thought to be associated with or related to the individual. Paid services, such as Spokeo and Intellius, provide deeper information, including current location, criminal records, arrest history, date of birth and marriage history. Spokeo and Intellius provide per-instance and monthly or yearly subscription plans between $2 and $30.
