I did, but some things were addressed to my new address out here, not just forwarded. Mailings from my insurance company and some stuff from my parents. Also some things from my mortage compnay all came back, and were addressed with the 85238 AC. I just put in an address change in from my PO BOX this week.

We've been here since April and have only had a few problems with the zip code. Most of the problems stem from credit cards who use the zip code to verify the card. If they haven't updated their system then it'll puke it back at you.  Only way to fix it is to keep bugging them to update their systems to THIS YEAR's standards. 85238 has been in effect since June of 07.

I managed to convince Ebay to update the zip code by throwing this link at them:

For the most part, I use 85238 for everything and haven't had any issues.  UPS and FedEx have it figured out so that's really all that matters.
