I know most of us these days rely on our cell phones, but this goes to show we need to be taking proactive steps to keep our children and families safe.
Google has implemented a feature which enables you to type a telephone number into the search bar and you will be given the person's name and address w/a Google Map. If you then hit Map you will get a map to the person's house. It's nationwide reverse telephone book.
If a child gives out his/her phone number, someone can now look it up to find out where he/she lives. The safety issues are obvious, and alarming; it could take Sex Offenders right to your front door!
Check your own number (although this may not apply to you if you have an unlisted number or cell phone as primary contact).
I checked this out and put in our phone number and was, indeed, able to locate our information. I followed through and asked for the "block". Likely worthwhile for each of us.
