NTEE / NAICS / SIC Crosswalk

This crosswalk provides a bridge between the National Taxonomy of Exempt Entities (NTEEs), the North American Industry Classification System, the Canadian variation of NAICS, and the Standard Industrial Classification systems.

NAICS is the current classification system managed by the U.S. Census Bureau and used in many parts of the federal government. The SIC system preceded it, but is still useful when using data from the 1990s or earlier.
