North American Industry Classification System (NAICS Codes) The Standard Industrial Classification (SIC) system is being phased out in favor of
the new North American Industry Classification System (NAICS). NAICS industries are identified
by a 6-digit code, in contrast to the 4-digit SIC code. The longer code accommodates the
larger number of sectors and allows more flexibility in designating subsectors. View NAICS index structure Search for a specific NAICS
