What are NAICS?
NAICS (North American Industry Classification System) codes are 6 digit numbers used to group organizations into industries based on their primary activities. To find information using a NAICS Code, type sic or naic followed by the number you want contained in parentheses. For example, naic(211112) finds documents dealing with natural gas mining. You should use the most specific code possible. Remember, the codes don’t cascade. If you enter 22 (Utilities), your search will return no records. If you want to broaden the search to include multiple codes, you need to use wildcard characters. For example, to find information on policies in all the subcategories of utilities, you would search for policies AND sic(22*).
