Classification Code List

Links to websites that contains rates, classification code lists by alphabet and numeric, and manuals.

We have the Indiana advisory rates by class code on our website. We do not have a listing of individual carrier rates like you see in California, but we do publish a Carrier Filings Report 
From our home page at, in the upper left hand corner, click on "MENU" then "RATES, then "Rate Pages." The pages display in Adobe Acrobat (PDF) file format.

Class Codes
NCCI website,​, has a "Lookup a Class Code or Rate" selection on its home page.

The Wisconsin Bureau has an online class code lookup. There would only be a handful of Wisconsin or Indiana state special codes, so most of the listing would also apply to Indiana. Here's the link:

A listing of NCCI class codes in both numeric and alpha formats is available to registered users from its on-line Scopes Manual.​ 
You may find the descriptions in several NCCI workers compensation manuals:
Basic Manual
Scopes Manual
Classification Codes and Statistical Codes Manual

You can purchase the manuals from NCCI by calling 800.622.4123 or going to its website at Most insurance agents and insurance companies have these manuals. If you just have a couple of codes you need descriptions for, you could call the ICRB at 317.842.2800.

Summary of Recent Changes
NCCI has made numerous updates to workers compensation classification codes in recent years. For information about updates, a summary list of national item filings, and the industries that were affected, please refer to the NCCI manual Classification Codes and Statistical Codes For Workers Compensation and Employers Liability Insurance, or the ICRB CompClues document titled "Filings List."

Classification Codes and Statistical Codes Manual is a historical record of classification and statistical codes. The online manual provides the code number and corresponding phraseology (filed code description) for each classification and statistical code, including state special codes and independent bureau codes. Use the manual to find out if a code is a state special, a federal classification, a statistical code, or has been discontinued. Most entries indicate the date a code became effective or was discontinued. You can also find out if a discontinued code has been reassigned or retained as a state special. In addition, the manual indicates the schedule (or general industry division) and group numbers.
