Yes, the 3-digit code is a nice short cut, but don't forget to blank it out (yet still get an error messate as if it's there) if you want to check corporate codes, and oh by the way, there are two different corporate codes for MVP depending upon which brand you're looking at. And again you have to blank out all the other codes if you also have AARP.
