What are industry classification codes?
They are codes created by the US government used to collect industry-wide statistics. Many reference sources use them as a way to organize industry and company information. NAICS replaced SIC in 1997, but some sources use both, some still use SIC only North American Industry Classification (NAICS) Created by the Census Bureau in 1997, NAICS replaced the SIC. NAICS includes many newer industries in addition to being a uniform classification system for Canada, the U.S., and Mexico. Like the SIC, it is hierarchical and classifies each industry by broad group and then subdivides each into smaller, more specific classification. Each industry is assigned a unique number. The NAICS is updated every five years and was last done in 2007 (updates: 1997, 2002, 2007); the most current version is online. Most changes happen in the technology sector. NAICS and SIC codes can be found in both print and online—the online version of NAICS is more up-to-date. Print: North American Industry Classification
