Industry Breakdown for North American Industry Classification System

NAICS codes are broken down by digit. The broadest description starts with the 2 digit sector codes. The 3 digit subsector codes are more specific, then the 4 digit industry group, 5 digit industry (Where you are now), and the most specific is the 6 digit NAICS code. If the code on this page does not describe the industry of the business in question, then select the largest applicable code below. From there, follow through the progression of smaller digits to the larger digits in order to obtain the most specific 6 digit classification.

  • Sector 21: Mining, Quarrying, and Oil and Gas Extraction
    • Subsector 212: Mining (except Oil and Gas)
