Do Amazon badges work at other fulfillment centers or just your building?

Random thought that popped into my head while standing at a station staring into the void. If you work at one FC and you walk into a completely different Amazon building, will your badge still scan and let you in? Or will the door basically be like “yeah… you don’t work here.” Not trying to go warehouse hopping or anything. One building already got me walking 20 miles a night. I’m just curious how the badge system works across different sites.

Like does it recognize you as an Amazon employee everywhere, or is it loyal to just your FC?
