What Are Workers' Comp Class Codes?
In the United States, several organizations categorize businesses and assign similar businesses a number, or classification code. This system helps ensure everyone's on the same page when it comes to workers' comp.
The National Council on Compensation Insurance (NCCI) developed a system that is the most commonly used in the U.S. for workers' compensation. It categorizes businesses into over 700 different codes, although the exact number can change as businesses evolve.

PA Workers' Comp Class Code System
Pennsylvania uses its own classification codes, created by the Pennsylvania Compensation Rating Bureau (PCRB), unlike most states that use the National Council on Compensation Insurance (NCCI) codes. The PCRB assigns each company a classification based on the types of work the business or workers engage in.
The PCRB's classification codes group similar businesses into a singular category to streamline the rating process, making it more efficient and accurate. If the employer, the PCRB, and the insurance company disagree on the classification, the employer can ask the PCRB to reevaluate the company and assign a different rating.
Insurance companies can create and assign subclassifications, which further categorize businesses into smaller categories, but these must be approved by the Pennsylvania Insurance Department. Each classification code (or subclassification) carries a different multiplier, used by the insurance company to determine the employer's premium.
For example, a roofer, tree trimmer, or demolition company may have a cost of $17 per $100 in payroll, while a business like an attorney, accountant, or real estate agent may have a cost under $0.20 per $100 of their payroll.
Here's a breakdown of how the PCRB's classification codes work:
Assigning and Looking Up Class Codes
Class codes are assigned based on the industry of the job, the duties performed by people in the position, the level of risk associated with those tasks, and the safety rating of the individual employer.

To ensure accuracy and consistency, employers can ask the PCRB to take a second look at the circumstances and assign a new code if the initial classification code doesn't match up.
The governing class code represents the overall product or service offered by your company and is the primary code used to determine workers' compensation rates.
Every business has a primary class code, but many companies have more than one class code.
To look up class codes, you can contact the governing body directly, such as the NCCI in Georgia, or use a third-party lookup tool.
The two most common supporting class codes are 8810 – Clerical Office Employees and 8742 – Salespersons Or Collectors – Outside.
These supporting roles are often office-based, lower risk, and therefore less expensive to insure.
Here are some common class codes and their descriptions:
If you feel like you're being charged too much for your workers' compensation insurance, contact your insurance company and ask them to review your codes.
Business and Certification Requirements
You'll need to check your workers' compensation certificate to find the class codes assigned to your business. This certificate should be readily available if you have or had workers' compensation insurance.
The class codes are usually a 3- or 4-digit number followed by a brief description of the business type. For example, 0042 is for Landscape Gardening & Drivers, while 5037 is for Painting.
To determine if your class code still accurately describes your business, ask yourself if the business has expanded into new services or hired staff that serves a supporting role. You may need to adjust payroll for specific class codes or overall if the business has changed.
What Is Payment?
Payment for workers' compensation insurance is determined by the type of work employees do and the risk associated with that work, which is categorized using class codes.
Insurance companies use these class codes to calculate rates for workers' compensation insurance and the required coverage.

Each state has its own rules about using a coding system to classify employees and industries, so employers with multiple locations need to be familiar with the codes used in each state where they do business.
This means employers must understand the specific class codes required in each state to ensure they're meeting their workers' compensation insurance obligations.

Verify the Certificate

The classification codes are usually a 3- or 4-digit number followed by a brief description of the business type, such as 0042 Landscape Gardening & Drivers.

- Does the classification code still describe what the business does?
- Has the business expanded into any services, or hired staff that serves a supporting role (e.g. clerical, sales, delivery)?
- Does payroll need to be adjusted, overall or for specific class codes?
The answers to these questions can help you determine if your class codes need to be updated.
