The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy.
Each U.S. industry has a 6-digit NAICS code. The 2017 NAICS consists of 1,057 6-digit codes.
In the DBE program, the types of work a firm can perform (whether on initial certification or when a new type of work is added) must be described in terms of the most specific available NAICS code for that type of work. For certain types of work, in addition to applying the appropriate NAICS code, the Ohio Unified Certification Program applies a descriptor from its own classification scheme. A correct NAICS code/descriptor is one that describes, as specifically as possible, the principal goods or services which the firm would provide to DOT recipients. Multiple NAICS codes/descriptors may be assigned where appropriate. (49 CFR 26.71(n)(1))
Search for codes on the NAICS website. In the "2017 NAICS Search" box on the left side of that page, enter a keyword that describes your kind of business. A list of primary business activities containing that keyword and the corresponding NAICS codes will appear.
