I did not answer, but did call the number back. Got an auto-answer (doesn't tell you the company) which gave the option to be placed on their do not call list. I do know that if you answer the original call it's a recording, if you click that number to be removed from their list it will disconnect the call and the calls keep coming.
they get your information from your county DMV. If you have a driver's license, or have a vehicle, atv, trailer registered in your name---you are now a target for these scammers !! Some states and counties will let you "opt out" of their list of names if you just sign a form.
