Real ID has been implemented in every state and most territories. Not all share their databases with each other, but that isn't a requirement for usage for using the ids for air travel in the US.
After a few big delays, the deadline for having a compliant id for domestic air travel is 2023-05-03.
I personally had a bad experience attempting to get a compliant id when I lived in Arizona. At the time you could select if you wanted a compliant id or a non-compliant id. My wife and I both selected on the form to get compliant driver's license. Unfortunately when the physical licenses came in the mail they had they weren't compliant and had text indicating they weren't valid for federal identification.
We tried to get them to change this and they refused. Friends had experienced the same issue at the time, but I've been told they now have valid ones that you can get more easily.
