Workers' Comp Class Codes — NCCI Class Code List & Lookup

Class code lookup — frequently asked questions

How do I find my workers' comp class code?

Match the type of work your employees perform to an NCCI classification, not your industry label. Start from the governing (highest-payroll) operation, then add any standard-exception codes such as 8810 clerical office, 8742 outside sales, or 7380 drivers. Use the search box on this page to look up a code by keyword, business type, or four-digit number, or confirm the assignment with your carrier or state rating bureau before a policy binds.

Are NCCI codes the same as WCIRB or state-bureau codes?

Not everywhere. In most states insurers use NCCI classifications, but 11 states run an independent rating bureau that publishes its own class-code system — including California (WCIRB), New York (NYCIRB), Pennsylvania (PCRB), New Jersey (NJCRIB), and Delaware (DCRB). A WCIRB class-code search returns California-specific codes that don't always map one-to-one to NCCI, so verify the code for the state where the work is performed.

Can one business have more than one class code?

Yes. Most employers carry one governing class code for their primary operation plus one or more standard-exception codes for clerical, outside sales, or driving staff whose payroll is reported separately. Splitting payroll across the correct codes is what keeps the premium accurate, because each code carries its own rate per $100 of payroll.

What is an NCCI workers' comp class code?

An NCCI class code is a four-digit number the National Council on Compensation Insurance assigns to a type of work to group employers with similar injury exposure and set a base rate per $100 of payroll. Higher-hazard work carries a higher code rate; the same code can carry a different rate in each state because loss costs are filed state by state.
