NAICS and SIC codes are important elements of industry research. Finding your industry's NAICS and SIC codes is a good starting point for your research, and will help you find materials in other resources as well. Many sources provide industry information based on these codes. Also, most directories that index companies by industry use SIC and/or NAICS codes.
SIC codes are 4-digits long, and are being largely phased out in favor of the NAICS codes- but are still used by some government agencies.
NAICS codesare 6-digits and classify industries according to type of economic activity (process of production) in Mexico, Canada, and the US. This allows for easier comparability across companies within the same industry.
