I just received a notification that reads the following:
Google has a feature where you can type in your phone number (i.e.414-123-4567), hit search and it will not only list your name and address but provide a map to your front door. If a child gave out their phone number someone could find him or her easily.
You can remove your number from the listing. When you search your phone number it provides an option to remove your listing. Unless you have a cell phone or unlisted phone as your primary contact you may want to retain your security by removing yourself.
(Go to www.google.com and try it. You'll see.)
