What is a NAICS code?

The North American Industry Classification System (NAICS) is used by businesses and governments to classify and measure economic activity in the United States, Canada, and Mexico. NAICS is a 6-digit code system that is currently the standard used by federal statistical agencies in classifying establishments (individual business locations).
