Has it been 2 years since you initially or recertified?
Do you have your NREMT number and it's current? You'll need it and a picture of your card to upload into AZ DHS.
Note that you don't have to keep your NREMT after your initial certification and can just be AZ certified, but if you ever want to go to a different state, we don't suggest giving up your NREMT - but do what is best for your situation.
