NAICS (North American Industry Classification System) codes classify businesses by industry. Government agencies use NAICS codes to identify the types of businesses eligible for contracts, analyze industries, and organize procurement opportunities.
Enter an industry keyword, business activity, or NAICS code to find matching NAICS classifications.
NAICS codes classify businesses by industry and are commonly used in government contracting. While not every government solicitation includes a NAICS code, many federal, state, and local procurement opportunities use NAICS codes to identify the industry associated with the procurement.
NAICS and FSC codes serve different purposes in government contracting. NAICS codes classify businesses by industry, while Federal Supply Classification (FSC) codes, commonly referred to today as Product Service Codes (PSC), classify the products and services purchased by government agencies. Understanding both systems can help vendors find more relevant contract opportunities.
