I think it's based on phonebooks.
Why? I have a cell phone, not a land line, and my name doesn't appear. My parents used to have two lines, and there's a seperate entry for them with each number. It might not be the only way they get info, but I'll bet most of it's from there.
It's not based on phone books. They have me living at place where I own property but have an unlisted number
If it's based on phonebooks, why does my name and ex's old address show up? It's the address he shared with his mom and brother while we were separated. I don't like this one bit.
