About SIC Codes

A SIC Code describes the primary business activity of a company. With more than 10,000 unique classifications, SIC codes have been extended to create the most accurate way to target businesses.

Businesses often use SIC codes to identify companies within specific industries for marketing purposes. By determining the SIC code of their best clients, they can use this information to successfully acquire more customers within that industry.

  • What does NEC - Not Elsewhere Classified mean in certain SIC Code titles?

    In the SIC Code system, miscellaneous 3rd or 4th digit codes are usually designated with the term 'Not Elsewhere Classified'. These codes typically end in the number "9". The NEC codes are the residual classifications that do not usually constitute homogenous primary activity groups. Therefore, for the purpose of the SIC system, they are grouped and treated as a separate industry in order to retain the homogeneity of the other industries in the group.

  • How many SIC Codes are there?

    In the official U.S. Government SIC Code system, there are a total of 1,514 codes (included in the 2-digit, 3-digit, and 4-digit levels). A very important part of the SIC Code system is that the U.S. Government had written into the SIC Code Manual that agencies could use additional subdivisions within specific four-digit industries to further break down industries. Private companies created 6, 7, and 8-digit SIC codes systems (known as Extended SIC Codes), which account for more specific sub-industries, as well as new and emerging industries. The Extended SIC Codes, with over 10,000 individual code classifications that are being continually updated, offer more specific targeting options than NAICS Codes.

  • Can I change my Company's SIC Code?

    A SIC Code is self-classified and the primary code associated with your company can change as your business evolves. If you find a specific agency or government office is using a SIC Code that doesn’t apply to your business, it is best to contact that specific agency/office and request an update. Typically, agencies will use SIC Codes at the 4-digit U.S. Government level, but you may encounter 6, 7, or 8-digit classifications as well. The SICCODE.com website provides a breakdown of each of these Extended SIC Code systems to assist with your self-classification.
