Standard Industrial Classification (SIC) codes are four-digit numerical codes that are used to identify the primary business activities of an establishment. You may look up your SIC codes here with OSHA.
To find out what your SIC codes are, you may call our Business License Department at (909) 625-9423 or look it up on your Stormwater Inspection Report. If you do not think the SIC code assigned to your business describes your business activities, please contact us at (909) 625-9447.
