Yes, it is free! And does not pretend to be free like some of the services out there that pretend to be free, but if you really want more information they will charge you an expensive fees. When I first came here in the State, the first thing I did is to look up some friends and classmates that immigrated here. I used a lot of free people search services but they will just inform me that they found the one that I've been looking for but they will not show you the complete address and phone number, if you want to know, there is a charge.
Now, there's a great way to find them, I used people finder and was very happy with the outcome, the searching is so easy, the complete address and phone number showed up without charging me anything. I contacted my long lost friend in California right away and she was surprised how I found her. Well, I told her about how I've been searching her for a long time now and uses a lot of search engine, until I found out about this lookupwho.com site that offers free search. Then we made a deal of searching for other classmates in high school who now lives here in the States and in Canada. The services is open to USA and Canada as of the moment.
Just enter the person's name, and state and they will provide you with more information about that person your looking for.
