The North American Industry Classification System (NAICS)

At the start of your research, it may not be clear what specific industry you should be examining. A good strategy is to find out if your business idea is classified in an industrial classification system. These systems organize industries by assigning them a numeric code. The most commonly used system is the North American Industry Classification System (NAICS).  Once you know your Industry Classification Code you can use this number to:

  • Find industry-specific statistics on government websites or in library databases
  • Generate lists of competitors in company directories

Another common classification system is the Standard Industry Code (SIC). NAICS have most replaced the SIC, but the SIC is still used by some commercial databases. Finding and using these classification systems to effectively search can be tricky, so don't hesitate to ask a librarian for help.
