I was going to post that but you beat me to it. I remember many radio announcements mentioning cities in Arizona that were actually in Arkansas. AR-AZ can really confuse someone.

I think it all traces back to the post office’s decision to make all state abbreviations two letters. Bad idea, in my opinion.
Arkansas used to be commonly abbreviated as ARK. No confusion there. So of course the government had to mess with it.
