Internet Tip: Got A Number, Need A Name
You may, on occasion, find a need for a "reverse" telephone lookup -- ie. you have a phone number, and want to know the name and address of the person at that number.
Try Infospace Reverse Lookup at http://www.infospace.com/_1_169174148_info/reverse.htm.No reverse lookup system is completely accurate, and the data is updated every few months so if it's a new number you may not be completely successful. But of all the reverse lookup capabilities on the Internet, this one is pretty good.
