I'm pretty sure the postal codes and state abbreviations pre-date Alaska statehood. As you may, or may not know, postal codes and state designations were assigned from the upper east coast, going down to Florida, move West a bit, go back north, over a bit, go back down to the Gulf, and so on. So AL was given to Alabama anyhow, by virtue of its geographic location. Some folks do confuse the Arkansas (AR) and Arizona (AZ) abbreviations, but Arkansas came first in the designation department. As a newspaper editor and later a magazine editor, I made those changes too many times to count. Sigh. Mary
