SIC (Standard Industrial Classification) Codes are 4-digit numerical codes used to classify businesses by industry. Established in the United States in 1937, it has since been replaced by the NAICS (North American Industry Classification System), though both systems are still in use today.
The first two digits of a SIC code identify the major industry group, such as Manufacturing or Transportation. The third digit identifies the industry group, such as Electronic Components under the Electronics category. Finally, the fourth digit identifies the industry. And if an industry cannot be located, the number “9” is used in the third or fourth digit position to show NEC or Not Elsewhere Classified industries.
SIC codes are important for many reasons. In addition to properly identifying a business, they are used for tax purposes, in government statistics, classification, state and federal registration, and to determine eligibility for government contracts. SIC codes provide an efficient way to analyze and report economic metrics and are required for certain forms and applications, such as business tax returns or when applying for a loan with the SBA (Small Business Administration).
