Why NAICS codes matter for federal contracts

Every federal contract is tagged with one NAICS code that names the industry the work belongs to. That code does three things at once: it determines which businesses are eligible to bid, it sets the SBA size standard that decides whether you compete as a small business or against full-size firms, and it controls which set-asides (8(a), HUBZone, SDVOSB, WOSB) apply. Choose the wrong code on your SAM.gov profile and you'll miss opportunities you qualify for; the right code is how federal buyers find you in the first place.

NAICS is one of several ways federal contracts are organized. These dimensions intersect — a single contract has a NAICS code, a set-aside, an issuing agency, and a place of performance.
