Industry Codes

To use some sources you will need a NAICS or SIC code for your industry.

North American Industry Classification System
The NAIC System assigns numerical codes to industries from two to six digits. Shorter codes represent broader industry sectors. Be sure to read the full description of the NAICS code, as it may include a broader array of products/services than you might assume.

Standard Industrial Classification Manual (at OSHA site)
The SIC system assigns numerical codes to industries from two to four digits. Shorter codes represent broader industry sectors. Be sure to read the full description of the SIC code, as it often includes a broader array of products/services than you might assume.

1. Identify the NAICS Code for your Industry


  • Search for different words or phrases.
  • Check the industry description to see if the NAICS code is the best match to your industry. One of the cross references may be a better match.
  • Try searching a shorter version of the code. Check if a shorter code for a broader industry segment or a different sub-code is a better match.
