In Tennessee, everyone over 16 is now able to get a vaccine. You have to have a Tennessee residence, which is validated when you make your appointment. Once you go to your appointment, you only have to show the email you got from signing up. I just got my first dose Thursday. I signed up for it Sunday, and spent about 30 minutes between getting in line and being able to drive off, never had to show my ID. In my state, they are begging people to get the shot and think we may hit a high of about 40% vaccinated.
