Users can find a phone number in an online directory, such as Whitepages, by entering the person's or business's name and address and clicking search. The search can be narrowed or broadened by the amount of information that is searched through the website.
There are many websites that provide user's phone number information including sites that offer reverse number lookups, lookups searching address, cell phone number or name. Some of the sites like People Finders do charge per lookup or offer memberships for unlimited searches. Sites like Whitepages do not charge for a phone number lookup searched by name, address or phone number.
