What Is a Standard Industrial Classification (SIC) Code?
The Standard Industrial Classification (SIC) code categorizes and organizes industries according to their business activities. It facilitates the classification and analysis of economic data across various industries and government agencies. SIC codes are not limited to the United States; they have also been implemented in the United Kingdom.
SIC codes consist of four digits that ensure uniformity in statistical data presentation by different government agencies. The entire SIC code represents a company's line of business, with the first two digits indicating the primary industry group, the third digit specifying the major industry group, and the fourth digit identifying the specific industry.
How Do SIC Codes Work?
The U.S. Census Bureau assigns SIC codes based on the North American Industry Classification System (NAICS), a detailed industry classification system used by the U.S. government.
SIC codes are used for many purposes, including:
- Tracking economic activity: To help government agencies monitor financial activity and analyze industry trends to support businesses and create jobs.
- Analyzing industry trends: This helps businesses understand industry trends and growth opportunities, guiding decisions on product development, marketing, and expansion.
- Classifying businesses: They classify businesses for taxes and regulations; lenders use them to evaluate creditworthiness.
SIC codes are valuable tools for businesses and government agencies. They allow them to track economic activity, analyze industry trends, and classify businesses.

How to Read SIC Codes
To read SIC codes, you need to understand the code's structure and the definitions of the different industry groups, subgroups, and industries. This information is in the SIC Manual, which the US Census Bureau publishes.
Once you understand the structure of SIC codes, use them to identify businesses and other organizations by their primary activity. There are over 1,000 possible SIC codes, and all companies have one. Companies that file public reports must typically use SIC codes when reporting. Additionally, the SEC uses SIC codes to assign review responsibility for company filing requirements.
What Is the Difference Between SIC Codes and NAICS Nodes?
Introduced in 1997, the NAICS codes were designed to replace the SIC codes for standardizing industry data collection and analysis in the US, Mexico, and Canada. Despite adopting NAICS codes, SIC codes remain popular due to their long-standing history.
Many companies and government agencies, including the Securities and Exchange Commission (SEC), use SIC codes to classify industries. Although the government stopped updating SIC codes in 1987, private data organizations have continued to update and expand the SIC system, resulting in over 10,000 six-digit codes, compared to 1,066 NAICS codes.
How Does the SEC use SIC Codes?
The SEC publishes a listing of standard SIC codes to assist with locating the correct reviewer of company filings based on the company's industry. Additionally, companies must report the SIC code that mode closely identifies with their operations when issuing reports.
SIC codes are more than just a numeric label; they’re a key that unlocks essential information for businesses and government agencies to track trends, classify industries, and make informed decisions.
While systems like NAICS have emerged, the importance and relevance of SIC codes remain. By understanding and using SIC codes, businesses can gain a deeper understanding of their industry, sharpen their business strategies, and position themselves for success.
