What is a NAICS code and how do I choose one?
A NAICS code is a 6-digit classification of your industry. In federal contracting it determines which opportunities you match and whether you qualify as a small business under that code’s size standard. Choose the code matching the bulk of your revenue as your primary.
NAICS (North American Industry Classification System) codes are six-digit codes that classify what your business does. Each code carries a small-business size standard — a revenue or employee-count ceiling — that determines whether you count as small for set-asides under that code.
Pick the code that matches most of your revenue as your primary, then add secondary codes for adjacent work so you appear in more searches.
