Sector/Industry classifications are often used to divide companies into industry groups. SIC is the best known, and companies have a Primary SIC code, and additional secondary ones.
The main sector/industry classifications are:
SIC codes (US), or Standard Industrial Classification codes, are maintained by OSHA (older that NAICS but widely used).
NAICS codes (US), or North American Industrial Classification System codes, are maintained by the Census Bureau. You can search for 2002 or 2007 NAICS codes.
The NAICS Association maintains a NAICS and SIC lookup page where you can look up an industry by either code, or both codes by industry name.
