Most of my life my SSN was also my drivers license number. Then my state a few years ago changed the numbers. Great! Now some hotels want to copy both sides of your license before renting you a room. My doctors office and local hospitals copy them too.
A few years ago, Capital One credit cards wouldn't let us pay our bill online, which we had done for several years, unless we sent them a copy of both sides of our DL's! I called them and said no thanks and they said I would have to began paying through the mail. We paid off both cards and canceled them.
Have said all this, it's prob just a matter of time before my DL number is hacked by someone through some weakly secured site.
