As of May 2015, some websites that allow users to get phone numbers by searching names include YellowPages.com, AnyWho.com, Whitepages.com and 411.com. The lookup service is also available at PeopleSmart.com.
At YellowPages.com, users enter a first name, last name, city or ZIP code, and state to search. The site doesn't require the user to fill all of the fields. A list of people who match the criteria appears with information such as their addresses and phone numbers and driving directions to their respective areas of residence. The same procedure applies for AnyWho.com, Whitepages.com, 411.com and PeopleSmart.com.
Search results at PeopleSmart.com and Whitepages.com show additional useful information, such as age ranges and possible relations.
