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.
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 a business librarian.
