Use these online resources to find the correct code for the industry you are researching.

Industry Codes

NAICS and SIC codes are used to standardize the collection of statistical data in the US, Canada and Mexico.  The goal is to produce common industry definitions for the three countries.  The federal government assigns the codes.

North American Industry Classification System (NAICS ) codes were adopted in 1997 to replace the old Standard Industrial Classification (SIC) system.  Many research resources, including databases, utilize NAICS and/or SIC codes for searching purposes.

Find NAICS and SIC codes for a specific industry using either a reference book or online resources, then use those numbers in your research.
