What is NAICS?
The North American Industry Classification System (NAICS) is the standard used by U.S. government statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy.
Does Demandbase map NAICS and SIC codes?
There is no industry standard mapping from NAICS to SIC. In general the mappings are business-specific. Demandbase does not define this mapping.
