The Standard Industrial Classification (SIC) code list is a system that groups similar industries together, regardless of what businesses might try to call themselves in order to get a lower insurance rate. Each business's SIC Code is found on its Business Entity System (B.E.S.) number, along with the federal ID number and address at which the company is registered. SIC codes are used by almost every government agency as a standard system to track businesses.
