NAICS Codes Directory

The Standard Industrial Classification (SIC) system was replaced by the North American Industry Classification System (NAICS) in 1997. NAICS provides a more detailed and updated classification of industries, reflecting the modern economy. While SIC codes are still used in some legacy contexts, NAICS codes are the current standard for federal statistical purposes, census data collection, and government contracting.

NAICS codes are reviewed and updated every five years to reflect changes in the economy, emerging industries, and new technologies. The most recent revision was published in 2022, which merged or redefined several retail, media, and technology classifications.

Yes, businesses with diverse operations can have multiple NAICS codes to represent different segments of their activities. However, for government registration (such as SAM.gov), you must select one primary NAICS code that represents your main line of business, and you can add as many secondary NAICS codes as apply to your capabilities.

To update your NAICS code, you can log in to your System for Award Management (SAM.gov) profile and edit your representations and certifications. You can add or delete secondary NAICS codes or change your primary NAICS code. Keeping these current is crucial to ensure you continue to qualify for solicitations and set-aside programs.

Yes, non-profit organizations are classified under the same NAICS codes as for-profit businesses depending on their industry activity. Additionally, many charitable, religious, civic, and professional associations fall under sector 813 (Religious, Grantmaking, Civic, Professional, and Similar Organizations).
