There are two ways to run a search:

1. Phone number look up – search for phone number by name or address.

2. Revers phone look up – search for name and address by phone number.

I have done few searches and the results were worryingly accurate (How the heck they know all of that?). In both cases the results show owner’s name, address, phone number and the occupation.

You can also register on the site, create your own listing and use it as your online profile. This way you have some level of control on what others see.

Additional features like free text messaging, area code look up, zip code look up and mobile carrier look up are provided as well.

Features:

• Find phone numbers and addresses online.
• List numbers and addresses of 180 million US adults.
• Search for numbers by address and name.
• Search for name and address by number.
• Mobile app and browser search add-ons are also supported.
• Additional services:
  – Free text messaging.
  - Area code look up.

WikiWorldBook also has a people search feature that allows you to find anyone on the web as long that person is registered on one of the major social networking sites. Search results consist of images from the web and matching profiles from social networking sites.

Another really useful feature is people tracing. Using this functionality you may create a profile for the person you’re looking for. What happens next, when someone searches for that name on one of the major search engines they will see that profile among the top results and know that you are looking for them. Very useful that allows users to trace lost friends and relatives.
