Workers' comp class code lookup
Search a plain-English directory of common workers' compensation classification categories. Type an occupation, a keyword, or a code number to narrow the list instantly.
General reference only. Class codes, their exact wording and how they apply vary by state and by rating bureau — several states run independent bureaus with their own numbering and exceptions. Nothing here assigns a code to your business: final class assignment comes from the carrier's underwriter based on your actual operations and payroll records.
