Alternate name
From wiki.gis.com
An optional geocoding technique, an alternate name table can be used to account for street segments that are referred to with more than one name. For example, the main road through the center of Saratoga Springs, NY is called Broadway, but portions of this road are also associated with State Highway 50, Route 29, Route 9, and Route 9N. In order to account for addresses that use any of these street names, an alternate name table can be used to check for the various names.
