NAICS codes and government contracting

Every federal contract opportunity on SAM.gov is tagged with a NAICS code — the primary classification system used by the US federal government to categorize business activity. State and Canadian portals follow similar classification schemes.

Your registered NAICS codes in SAM.gov directly affect which set-aside contracts you're eligible for and how contracting officers find you for sole-source awards. Registering the right codes — and monitoring them consistently — is one of the highest-leverage activities in government contracting.

Small business size standards are also defined by NAICS code. The SBA assigns a revenue or employee threshold to each code — determining whether your business qualifies as a small business for that specific procurement. A business can be a small business under one NAICS code and not under another.

BidEdgeHQ monitors every NAICS code you add to your profile across SAM.gov and 200+ state and Canadian portals simultaneously. When a new opportunity posts under your codes, you get an AI match score, key details, and a WhatsApp alert — instantly.

Monitor your NAICS codes.
Automatically.

Add your codes once. We watch 200+ portals and alert you the moment something relevant drops.
