What Is SIC Code?

An in-depth look at Standard Industrial Classification (SIC) Codes used to classify industries by a four-digit code system, before being replaced by the NAICS system.

The Standard Industrial Classification (SIC) is a system that was used to classify industries by a four-digit code. While largely supplanted by the North American Industry Classification System (NAICS) in 1997, SIC codes continue to be a valuable reference for a wide range of business and governmental contexts.

What Is SIC Code?

A Standard Industrial Classification (SIC) code is a four-digit numerical code assigned by the U.S. government to business establishments to identify the primary business of the company. Created to facilitate the collection, analysis, and reporting of statistical data, SIC codes were essential for understanding and comparing the economic activities of various industries.

Definition

The SIC code system categorizes businesses into industries based on their primary activities. Each SIC code consists of four digits:

1. The first two digits represent the major industry group.
2. The third digit signifies the industry group within the major industry.
3. The fourth digit specifies the particular industry.

History of SIC Codes

The SIC system was established in the United States in 1937 to streamline economic data reporting and analysis. The system was regularly updated, most notably in 1987, to better reflect the evolving economy. The SIC system was officially replaced by the NAICS system in 1997, which provides a more modern and comprehensive framework for industry classification.

Conversion to NAICS

Despite the transition to NAICS, SIC codes remain in use by various entities, including some regulatory agencies and universities. For historical data consistency and certain regulatory requirements, SIC codes are still relevant. The main difference between SIC and NAICS is that NAICS uses a six-digit code and provides more detail about the industries.

Example of SIC Code Usage

For instance, consider a company manufacturing chocolate and cocoa products:

• SIC Code 2066: This specific code represents establishments primarily engaged in manufacturing chocolate and cocoa products.

Special Considerations

When using SIC codes, several considerations should be taken into account:

• Industry Evolutions: Since the SIC system was last updated in 1987, emerging industries may not have specific codes.
• International Comparisons: SIC codes are primarily used in the U.S. and may not align perfectly with international classification systems.

FAQs

What does SIC stand for?

SIC stands for Standard Industrial Classification.

Are SIC codes still in use today?

While the NAICS has largely replaced SIC codes, they are still used for historical data analysis and certain regulatory contexts.

How do SIC codes differ from NAICS codes?

SIC codes use a four-digit system, while NAICS codes use a six-digit system that provides more detailed classification.

Where can I find the SIC code for my business?

SIC codes can be found via various online databases and government websites, including the U.S. Securities and Exchange Commission (SEC).

Summary

Standard Industrial Classification (SIC) Codes played a crucial role in the structuring and analysis of economic activity in various industries within the United States. Although largely replaced by the NAICS system in 1997, SIC codes continue to offer historical reference and are still used in specific regulatory environments. Understanding SIC codes and their transition to NAICS is essential for accurate industry analysis and compliance.
