NAICS and SIC Codes

NAICS (pronounced nakes) - North American Industry Classification System Codes 

SIC (pronounced S-I-C) - Standard Industrial Classification Codes

NAICS and SIC are used to classify the industry in which a business operates.  The Federal Government introduced NAICS in 1997 to replace SIC.  Many research databases use NAICS and/or SIC codes for searching purposes.
