What is a NAICS code and where can I locate it? What is the industry title? What is the title of the NAICS code?


The North American Industry Classification System (NAICS) is a standard used by federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. NAICS codes can be found online at the U.S. Census Bureau website (https://www.census.gov/naics/). Applicants should use the Census Bureau website to determine the NAICS code that best describes their primary business activity.
NAICS codes are also assigned by the Louisiana Workforce Commission when a business registers for workmen’s compensation.
The Louisiana Department of Revenue uses the NAICS code to determine if a business is eligible for the Louisiana Resale Certificate. New businesses are automatically issued a Louisiana Resale Certificate if the NAICS code indicates sales are part of the business activity.
