NAICS: Classification code for my business
Question:How can I look up the North American Industry Classification System (NAICS) code for my business?
Answer:At www.census.gov/naics/, enter a key word in the search box in the upper left corner, then pick the best code from the list returned. Then click on the code to see the formal definition of the category.

It is not possible to look up a NAICS code by company name.
