Frequently Asked Questions
What are NAICS codes and how do I identify them?
The North American Industry Classification System (NAICS) codes are a standardized classification of various industries, and can be associated with specific companies (the codes reflect the industry of which the company is a part). NAICS codes are used in many business research databases in addition to statistical publications of the U.S. Census Bureau.
When doing business research, it is always helpful to know the NAICS code for your particular industry or company. A NAICS code lookup is available from the U.S. Census Bureau. The Industry Statistics Sampler data based on NAICS code is useful, and the American FactFinder Quick Reports based on Economic Census data can also be helpful.
Although the NAICS codes were meant to replace the older system of Standard Industrial Classification (SIC), these codes are still in use by some information sources.
