AnyWho.com is a neat little site that has information from nationwide White Pages, Yellow Pages, Maps and Directions. A real Swiss Army knife of business, and residential data.
This domain was first registered and launched in 1998 & allows it’s visitors to freely find a person or a business with relative ease and incomplete informtion. What it does charge for however is getting info on that person like background checks, and email addresses. It seems to use a company called intelius.com for this service, and I’m guessing they receive a kickback or some sort of affiliate commission.
I searched for myself and found a few persons in my area that have the same name, and of course it had my Address, Phone, and Name. Pretty good for a free service right?
The also offer a super cool reverse lookup feature, with a map integrated. http://www.anywho.com/rl
