This window1) provides a way for you to control how city and county names are spelled and/or abbreviated. When we introduced our naming rules, there were many inconsistencies in the names as they existed in the Rate & Boundary Database Our naming rules provide a way to standardize the names which makes it easier to lookup a city with the DZ Zip Address Lookup window.

This can be important when manually selecting a tax schedule, or when verifying the Tax Schedule Selection.
