Temp AOR is one that they will give you if you call and have an inquiry about your app or if you are trying to add something to your app. They will give you a temp AOR with a temp file # that starts with an X. They will do this if they have not yet verified the contents of your app. Once the contents are verified, you will receive an AOR with the same file # but the X will be removed. That signals that they will begin to process your app for completion and approval - the process has actually begun at this point.
