You are wrong, sir. (not sure what your coast of residency has to do with anything)
Every state Is
NOT a licensed state. NY, PA, NC, SC, GA, FL, AL, TN, MS, KY, IN, IL, LA, MO, KS, AZ, NV, CA, DC, MD, VA,
Some of those states may have a state Journeyman electrical licenses; but they're
not required to perform electrical in those states.
Mike Holt Enterprises - The Leader in Electrical Training. - https://www.mikeholt.com/statelicense.php - this is one place to look for specifics.
I have worked in many states without having a license myself. I've bought (state approved) temporary cards & apprentice cards, in order to work in some of those places. Some have special rules that exempt the license, like Native American reservations, ie: Foxwoods casino & Mohegan Sun; also power generating plants (which are Federally operated). If the job needs to be manned up, they find a way to get qualified JW's there; with or without licenses.
That yellow dues receipt, showed my qualifications to the contractors.
Happy holidays to you as well.
