NAICS and SIC Codes

NAICS (North American Industry Classification System) and SIC (Standard Industry Classification) codes are an easy way to group companies engaged in the same economic activities, like mining, retail, or health care.

SIC was used by the US and Canadian governments until 1987, when both countries adopted NAICS.  Some commercial databases continue to use SIC, however.
