What are NAICS codes?
NAICS (North American Industry Classification System) codes are 6-digit numbers that classify businesses by industry for federal statistics and contracting.
Why do I need them?
NAICS codes are required for SAM.gov registration, federal contracting, SBA size standard determination, and many certification applications.
SBA Size Standards
Each NAICS code has an SBA size standard (employees or revenue) that determines if your business qualifies as "small" for federal programs.
