Understanding NAICS Codes
NAICS (North American Industry Classification System) codes are how the federal government classifies your business by industry. Your NAICS code determines your SBA size standard (the revenue threshold for being classified as a small business) and affects which federal contracts you're eligible for.
Unlike the federal FAR or agency-specific procurement rules, NAICS codes are standardized across all government procurement. When you register in SAM.gov, you select your primary NAICS code and up to four additional secondary codes.
Federal procurement officers search for vendors by NAICS code. Choosing the right codes directly affects your visibility—if you're classified under the wrong code, agencies won't find you when searching for your services.
Size standards vary significantly by NAICS code. For example, software publishing (511210) has a $8.5 million size standard, while custom computer programming (541511) has a $34 million standard. Your size classification affects eligibility for small business set-asides and programs.
Classify Your Business Correctly
Your NAICS code determines your size standard, visibility to federal buyers, and eligibility for set-asides. Get it right to maximize your federal contracting opportunities.
