Look up any North American Industry Classification System (NAICS) 2022 code: official title, description, full hierarchy, over 20,000 official Census index terms and the official cross-reference rules, plus a crosswalk to NAICS 2017. Adds the SBA small-business size standard for a code (13 CFR 121.201), rule-based classification of a business description to a single defensible code, and an industry risk profile for KYB and underwriting screening. NAICS is a work of the U.S. Government and is in the public domain under 17 U.S.C. 105. API Ninjas is not affiliated with, endorsed by, or sponsored by the U.S. Census Bureau, the U.S. Office of Management and Budget, or the U.S. Small Business Administration. Size-standard results are informational and are not SBA size determinations. The risk profile describes an industry, never a specific business; it is not a compliance determination, not a consumer report, and must not be the sole basis for denying service to a business.
