Why NAICS matters
NAICS codes classify business activity. Buyers and primes often search by NAICS to find firms that typically perform related work.
Browse GovVendorFinder NAICS hubs for vendor lists, then open profiles for UEI, location, and award context.
Limits of NAICS matching
A listed NAICS does not guarantee past performance or eligibility. Multiple codes may apply; primary NAICS may lag source updates.
