NAICS and SIC codes help classify and measure industry activity. Knowing the code for your industry will help you find reports, articles, and other information on that industry.
The NAICS (North American Industry Classification System) is gradually replacing the Standard Industrial Classification (SIC) system.
Even though the codes are standardized, different resources will assign codes differently. Additionally, many companies can have multiple codes because of their various business segments. Be flexible and cautious when using codes to search, and always check multiple sources.
Note: Sometimes there isn't a perfect or obvious code. If you have questions, please contact Michael or Laura.
To look up codes by keyword, use the following sites.
If you already have a company but don't know what code(s) are associated with it, try the following database.
