How NAICS Codes Relate to CAGE Codes
When you register in SAM.gov and receive a CAGE code, your primary NAICS code is recorded in your entity profile. Anyone decoding your CAGE code can see your NAICS — it tells them your industry, your size standard, and the type of work you perform. Picking the right NAICS code is critical for small business set-aside eligibility.
