Nothing yet, probably wont be anything. But I am a well armed male. Imagine someone stalking a young woman. Bingo, I know where she works, I know where she lives. That is not right. Zip code should be enough. Nobody needs know your exact address for this kind of thing.
Most people with publish numbers also have an address in the phone book.
Ever googled your phone number?
