The Standard Industrial Classification (SIC) is a system for classifying industries by a four-digit code. If the search terms are less than 4 digits, SEED looks for SIC codes that start with these numbers, so a search for “4” returns companies with SICs between 4000 and 4999.
SIC codes correspond to these twelve divisions:
| SIC Codes | Division |
|---|---|
| 0100-0999 | Agriculture, Forestry and Fishing |
| 1000-1499 | Mining |
| 1500-1799 | Construction |
| 1800-1999 | not used |
| 2000-3999 | Manufacturing |
| 4000-4999 | Transportation, Communications, Electric, Gas and Sanitary service |
| 5000-5199 | Wholesale Trade |
| 5200-5999 | Retail Trade |
| 6000-6799 | Finance, Insurance and Real Estate |
| 7000-8999 | Services |
| 9100-9729 | Public Administration |
| 9900-9999 | Nonclassifiable |
