I'm afraid I can't remember the specifics? But the gist is, my wife and I use to travel a lot because she was a traveling nurse working for an agency that provided 6, 9 and 12 month assignments. We lived in Massachusetts, North Carolina, both coasts of Florida and always kept our home address in NH. When we decided to have children, we moved back to NH to be near our parents and bought a house. This was before the Internet.
Years later, we got something like a cable and ISP bill that was questionable. When we called the company to make sure the service was cancelled, or whatever it was, the automatic identity check asked a number of identifying questions, home phone number, mother's maiden name, ... it was more than a little excessive, but the one that got us was the one about what our apartment number was in 1987.
We couldn't even remember which city we were living in, in 1987. How is it that they knew, much less cared, what apartment we were in before there even was an Internet to keep track of us?
