NAICS codes
Tomba classifies companies with North American Industry Classification System (NAICS) codes. The code lists hold six-digit codes: the first two digits give the sector, and each further digit narrows the industry.
Where codes appear
| Field or filter | Endpoint | Content |
|---|---|---|
category.naicsCode | GET /companies/find, and data.company.category in GET /combined/find | NAICS code of the company's industry. |
category.naics6Codes | Same | Six-digit NAICS codes. |
category.naics6Codes2022 | Same | Six-digit codes from the 2022 edition of NAICS. |
filters.naics.include, filters.naics.exclude | POST /reveal/search | Up to 50 codes each. A code matches a company when it's in the company's naics6Codes or naics6Codes2022. |
The company search filter matches whole six-digit codes: 522320 matches, and a shorter prefix such as 52 doesn't.

The U.S. Census Bureau publishes the NAICS manual and a code search at census.gov/naics.
