What is a Standard Industrial Classification (SIC) code?
A SIC code is the Standard Industrial Classification number listed in the Standard Industrial Classification Manual which is published by the Office of Management and Budget. The SIC Manual is available at your local library or on the Internet site http://www.osha.gov/oshstats. SIC codes are used by the Federal Government to identify and classify specific categories of business activity that represent the primary line of business of a firm. SBA size standards are based on SIC codes.
A SIC code is a code representing a category within the Standard Industrial Classification System administered by the Statistical Policy Division of the U.S. Office of Management and Budget. The system was established to classify all industries in the US economy. A two-digit code designates each major industry group, which is coupled with a second two-digit code representing subcategories.
