Zip code error message

[steveoh]

Since we started analyzing geocode request by zip code and can see many zip codes are used that are outside of utah, we can respond to the caller that the zip code is in fact outside of utah.

If our zip code area's are complete and stay current and we can keep them that way, using that list and some conventions that utah zip codes start with 84... we can respond with a message that the zip code is outside of utah or invalid.

This is a good idea. It will be a nice enhancement to give the user feedback as to why the match failed. Ensuring the zip begins with 84___ is a simple and quick way to identify Utah.
