Industry Codes

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 mostly 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.

NAICS / SIC codes do not identify whether a business is home-based or not, but can be useful in researching the specific industry that your home-based business operates within. Here are a few examples of how NAICS codes relate to specific industries and business types.

Here are some examples

Type Code Description
NAICS 54 Professional, Scientific and Technical Services
NAICS 56 Administrative and Support, Waste Management and Remediation Services
NAICS 61 Educational Services
NAICS 541930 Translation and Interpretation Services
NAICS 561410 Document Preparation Services
NAICS 611610 Fine Arts Schools

Search or browse all NAICS or SIC codes on the NAICS Association website. Some NAICS codes are different in Canada — you can search by keyword or browse Canadian NAICS codes at Statistics Canada or Canadian Industry Statistics. To search for a SIC code using a NAICS code and vice versa, use the NAICS & SIC Crosswalks.
