Small Business, NAICS, SIC & You
Are you thinking of opening a small business? Find out what you need to know about NAICS and SIC codes before you open.
NAICS
NAICS stands for the North American Industry Classification System. It is the current standard used by the federal government for classifying businesses. It groups establishments into industries based on the similarity of their products, services, and production. The system was adopted in 1997 and updated in 2007 and again in 2012. More specific industries have more numbers. For an example of the tiered arrangement, visit this page explaining the NAICS definition of "Accommodation and Food Services" (72) via the U.S. Census, the official NAICS site.
SIC
SIC, or the Standard Industrial Classification, is a classification system similar to NAICS in that they both classify establishments by their primary type of activity. SIC was replaced by NAICS in 1997, but several data sets are still available with SIC-based data. One major difference between SIC and NAICS classification is that SIC tends to be broader where the NAICS is more specific, especially when it comes to new and emerging industries.
If given a choice to use the NAICS or SIC when conducting business research choose the NAICS code because it is newer and will have the most up to date industry information, statistics, and news.
These codes are used in the Economic Census and in different databases including Business Insights: Global, Reference USA, and others.
To look up a code for a particular industry, visit the official NAICS website via Census.gov and do a keyword search for your industry.
Conversion tables for NAICS and SIC are available here and here.
