Industry Information

The North American Industry Classification System (NAICS) supersedes the U.S. Standard Industrial Classification (SIC) system (see below). There is a keyword search and tables to convert from SIC to NAICS and vice-versa. A complete overview of the NAICS scheme is also available.

Browse by category or search by keyword to obtain the 4-digit SIC code for a product or service. This site uses the 1987 version of the SIC manual, which is superseded by NAICS (see above).

The Industry Classification Benchmark (ICB) is an industry classification taxonomy launched by Dow Jones and FTSE in 2005 and now used by FTSE International and STOXX. It is used to segregate markets into sectors within the macroeconomy. The ICB uses a system of 11 industries, partitioned into 20 supersectors, which are further divided into 45 sectors, which then contain 173 subsectors.[1][2]

The ICB is used globally (though not universally) to divide the market into increasingly specific categories, allowing investors to compare industry trends between well-defined subsectors. The ICB replaced the legacy FTSE and Dow Jones classification systems on 3 January 2006, and is used today by the NASDAQ, NYSE and several other markets around the globe. All ICB sectors are represented on the New York Stock Exchange except Equity Investment Instruments (8980) and Nonequity Investment Instruments (8990).[3]

Dow Jones divested itself of its 50% interest in the ICB in 2011 and announced it was creating its own version of it.[4]
