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 6-digit code system that is the current standard used by federal statistical agencies in classifying establishments (individual business locations). NAICS organizes establishments into industries according to the similarity in the processes used to produce goods or services. (See: What is a SIC Code?)
NAICS codes array the economy into 20 sectors, which are separated into 96 3-digit subsectors, which are divided into 308 4-digit industry groups, which are further subdivided into 689 5-digit industries, and finally disaggregated into 1012 6-digit U.S. industries.
What is a Primary NAICS Code?
Each and every company will have a primary NAICS code. This number indicates a company’s primary line of business. What determines a company’s primary NAICS code is the code definition that generates the highest revenue for that company at a specific location in the past year.
