The Standard Industrial Classification (SIC) is a system for classifying industries by a four-digit code. The SIC codes can be grouped into progressively broader industry classifications: industry group, major group, and division. The first two digits represent the highest-level business classification, while the subsequent two digits are used to further refine the identification. Each division encompasses a range of SIC codes.
|Range of SIC Codes||Division|
|0100-0999||Agriculture, Forestry and Fishing|
|4000-4999||Transportation, Communications, Electric, Gas and Sanitary service|
|6000-6799||Finance, Insurance and Real Estate|
