Has anyone ever checked out whitepages.com.  I used it to get the zip code for a friend of mine.  It brought up not only her name, address, and phone number; but it also gave her age. 
I have an unlisted phone number, but for me it still brought up my name, address (with the correct apartment number), and my age.  True, it made me a year younger than I am, but I still think that is kind of scary.  The reason I had an unlisted number was so that when I was working as a Welfare worker, none of my clients would know my phone number or my address.  Now the only secret is my phone number.  Creepy!
