How to Find Your Workers' Comp Class Code as a Contractor

What Is a Workers' Comp Class Code?

A workers' compensation class code is a classification assigned to a business (or a specific type of work within a business) that describes the nature of the work being performed. Rating bureaus and insurers use these codes to price workers' comp premiums, because injury risk varies enormously across occupations — a bookkeeper and a roofer are not the same risk, even if they technically work for the same construction company.

Every class code is tied to a rate. Your payroll for the work under that code, multiplied by the code's rate, forms the basis of your workers' comp premium (before other adjustments like experience modifiers, credits, or state-specific factors). Get the code wrong, and your pricing — and potentially your compliance — is wrong too.

Why Your Class Code Matters for Pricing

Class codes exist because insurers need a consistent, standardized way to price risk across an enormous range of occupations. For contractors, this matters in a few specific ways:

• Higher-risk trades cost more. Trades involving height, heavy equipment, or structural work (roofing, framing, excavation) generally carry higher class code rates than lower-risk trades (interior finish work, certain handyman services).
• Your code should match your actual work, not your business name. "Contractor" isn't a code — the code reflects the specific operations being performed, regardless of what your business calls itself.
• Multiple codes are common. If your business performs more than one type of work — say, a general contractor who also does roofing repairs in-house — payroll may need to be split and coded separately for each type of work performed.
• Misclassification creates real financial risk. If your business is coded too broadly, too narrowly, or simply incorrectly, you risk either overpaying at renewal or facing a premium adjustment at audit if your actual work is found to fall under a higher-rated code.

How to Find or Look Up Your Class Code

1. Start with your current policy, if you have one. Your existing workers' comp policy or audit paperwork should list the class code(s) currently assigned to your payroll.
2. Talk to your agent. This is the most reliable path — an agent familiar with contractor classifications can match your actual scope of work to the correct code(s) rather than relying on a generic guess.
3. Use a class code lookup resource. Many agencies, including ours, offer a class code lookup guide designed specifically to help contractors identify the code that matches their trade. If you're unsure where your work falls, that's a good starting point before finalizing anything with your agent.
4. Describe your actual operations, not your job title. When working through classification, focus on what the work physically involves — working at height, underground work, use of heavy equipment, interior vs. exterior work — rather than just your trade's common name, since this level of detail is often what separates one code from another.
5. Check state-specific rating bureau guidance where applicable. Some states use their own rating bureaus with state-specific code sets rather than the national standard, so the correct code can vary depending on where you operate.

Common Codes for Different Trades (Illustrative Examples)

Class codes and their exact numbers vary by state and rating bureau, so treat the examples below as illustrative of how classification tends to work by trade — not as authoritative code numbers to use on an application. Always confirm your actual code with your agent or a class code lookup resource.

• General contractors are often classified based on the type of building work being supervised or performed directly, and may carry a different code than the subs they hire.
• Roofers typically fall under a distinct, higher-rated classification reflecting the elevated fall risk associated with roofing work.
• Electricians are usually classified separately depending on whether work is primarily inside finished structures or includes higher-risk work like new construction wiring.
• Plumbers commonly have their own classification, which may vary depending on whether work includes new construction versus repair/service work.
• HVAC contractors are typically coded based on installation versus service work, since the risk profile can differ between the two.
• Framers generally fall under a structural carpentry classification, which tends to carry a higher rate given the nature of framing work.
• Concrete contractors usually have a dedicated classification reflecting the physical demands and equipment involved in concrete work.
• Landscaping contractors are typically classified separately from general construction trades, often with rates reflecting equipment use and outdoor labor.
• Handyman businesses may be classified differently depending on whether the work includes higher-risk tasks like roof or ladder work versus strictly interior, ground-level work.
• Remodelers are often classified based on the primary scope of the remodeling work performed, which can span multiple codes if the work is broad.

Because exact codes and rates differ by state, the right move is always to confirm your specific classification rather than assume based on trade name alone. Our class code lookup guide is built to help walk contractors through exactly this process.

What to Do If Your Trade Doesn't Fit Neatly Into One Code

Plenty of contracting businesses don't fall cleanly into a single classification — a remodeling company might do framing, electrical, and plumbing work all under one roof, or a "general contractor" might spend half their time doing hands-on roofing repairs. If that's you:

• Expect to potentially carry multiple codes. It's common and normal for a business with diverse operations to have payroll split across more than one classification.
• Keep clean payroll records by task or crew. If you can clearly document which employees (or which hours) went toward which type of work, it's much easier to apply the correct code to the correct portion of payroll — and much easier to defend at audit time.
• Don't default to the broadest or cheapest-sounding code. Choosing a lower-rated code that doesn't actually match your work is a common way businesses end up with a costly correction at audit.
• Work directly with your agent on ambiguous cases. Classification isn't always obvious from the outside, and an agent experienced with contractors can help identify the most accurate code(s) for a mixed-scope business.

Frequently Asked Questions

What happens if my business is assigned the wrong class code? It can lead to either overpaying (if the code is rated too high for your actual work) or a premium adjustment at audit (if your actual work is found to fall under a higher-rated code than what you were charged for). Getting it right upfront avoids both outcomes.

Can I choose my own class code? Not exactly — the code is meant to reflect your actual operations as determined through underwriting, not a preference. However, you play an important role by accurately describing your work, since vague or incomplete descriptions can lead to an inaccurate classification.

Do class codes affect my general liability pricing too? Class/classification information can factor into GL pricing as well, though workers' comp is where classification has the most direct and standardized impact on rate calculation.

Where can I look up my class code before calling an agent? Our class code lookup guide is designed to help contractors get a preliminary sense of where their trade fits before finalizing classification with an agent — a good first step if you're unsure where to start.

Get Your Classification Right

An accurate class code isn't just a compliance detail — it directly affects what you pay and whether you're protected the way you think you are. If you're not sure your business is classified correctly, it's worth a conversation before your next renewal or audit.
