Yes there are some strange address types out there. It is not the Post Office that determines addresses, but local government units. I have helped many businesses "fix" their address in Goggle Maps. Using the Google Map Maker tool can pinpoint addresses for Google Maps and Navigation to accurately find any location. Also please remember that mailing addresses and actual location addresses are not the same thing. One is used to get your mail to you, the other to give a physical location. Most often they are the same but not always.
