Understanding NAICS Codes in Federal Contracting

What is a NAICS Code?

The North American Industry Classification System (NAICS) is the standard used by federal agencies to classify businesses by industry. Every federal contract is assigned a primary NAICS code that determines:

  • Small business size standards for the contract
  • Which contractors are eligible to compete
  • Industry benchmarks for pricing and performance

Choosing Your NAICS Codes

When registering in SAM.gov, you can select multiple NAICS codes that represent your company's capabilities. Consider these factors:

  • Primary:Your main line of business with the most revenue
  • Secondary:Additional capabilities you can perform
  • Size:Check size standards to qualify as small business
  • Experience:Only claim codes where you have past performance
