Free Reverse Phone Number Directory

i am trying to find a name and address of a cell phone free of charge?

i am trying to find a Reverse Directory on a Phone Number, i am not sure if it is a cell phone or land line

try whitepages.com, they have a reverse directory where you can just type in the phone number knowing nothing else about it. if its an unlisted number it’ll give you the name of the phone company that owns that number.
