A set of guidelines that define the format of addresses and methods of matching that can be used for a specific application.
In ArcView 3.x, specifies the address fields contained in the reference theme and address event table that will be used for geocoding. Each supported address style requires specific address fields. Geocoding tabular data based on an address style that requires few address fields may result in faster geocoding, but feature locations may not be as accurate as those produced using an address style with more address fields. In ArcGIS, address styles are called geocoding styles.
