Data Exchange Description
The North American Industry Classification System (NAICS) classifies business establishments for the purpose of collecting, analyzing, and publishing statistical data. It is a standard business classification scheme used by the United States, Canada, and Mexico. Every five years, an updated set of NAICS codes is released. EPA’s System of Registries now includes the current standardized list of NAICS codes, available through a series of web service queries for use by environmental programs and partners. There are four services available, such as returning NAICS information by code, definition, and keyword.
The NAICS schema and supporting flow documentation have been approved for use on the Exchange Network. Implementation resources for the most recent version follow.
