People Lookup is a popular online search engine whereby you can search for people by name, phone number, address, or email. The website has no advertisements of any kind other than for its own products which are paid search products.

People Lookup advertises itself as “the most complete, accurate people search tool on the web.” By paying a fee, a user can obtain access to more details. Complete background checks, including financial records (liens, judgments, bankruptcies), criminal records, address histories, and aliases are available for a fee.

People Lookup also allows users (for a fee) to search by Social Security number, cell phone number, or address. These paid services are used primarily by people researching new or prospective dates, and companies investigating employees. Many landlords now utilize this type of service to run a check on prospective tenants.

More than 2.7 million users visit People Lookup on a monthly basis, with the site hitting a peak in traffic during the latter portion of December, 2009. Over two-thirds of visitors are 35 and over, 81% are Caucasian, and more than 74% have no kids (another reflection of its use as a dating tool).
