> A couple years ago there was a thing that you couldn't get through airport security with an Arizona drivers license but had to go get an ID card that complied with federal rules, not sure what ever happened with that though. This is still a thing, not sure about AZ specifically. https://en.wikipedia.org/wiki/Real_ID_Act https://en.wikipedia.org/wiki/Real_ID_Act Basically says that if your state doesn't dump DL/ID info into federal databases, and some other requirements, you can't use it for some things federally - and so effectively creates a 'National ID' without overtly doing so.
