Business City or State Key Type File

The city or state key type file (bizCityorStateTypeKeys.dat) lists various cities and states that might be used in business names. It also classifies each entry as a city (CT) or state (ST) and indicates the country in which the city or state is located. This enables the standardization engine to recognize and process these values correctly. You can add entries to the city or state key type file using the following syntax.
