What Are Insurance Lines of Authority? A Guide for Agencies and Carriers

Article key points:

• A line of authority (LOA) is a subject area or type of insurance that an insurance producer can sell.
• LOAs are used to group similar products together for insurance licensing purposes.
• There are six major LOAs defined by the National Association of Insurance Commissioners (NAIC): life, accident and health or sickness, property, casualty, variable life and variable annuity, and personal lines.
• Limited lines LOAs cover only a specific type of insurance product and have less rigorous training requirements.
• States may have different insurance licensing requirements for limited lines, so it’s important to check with the state department of insurance website to confirm compliance.

Having a foundational understanding of key concepts can be the difference between success or failure in any industry. But when it comes to insurance, the basics just never really seem so basic. 

Our insurance 101 series seeks to address this problem by offering up clear, jargon-free explanations of important insurance topics. And while we’ve previously explored agent license renewals and regulating distribution channels, today we’re here to deep dive into lines of authority (LOA).

What is a line of authority (LOA) in insurance licensing?

A line of authority (LOA) is a subject area or flavor of insurance that an insurance producer can sell. Understanding insurance lines of authority (LOAs) is critical for insurance agencies, carriers, and MGAs managing producer licensing, compliance, and distribution operations across multiple states.

There are tons of things you can be insured for. Do you own a house? Maybe you have homeowners insurance. Do you live in the United States? Maybe you have health insurance. Have you ever bought a flight? Maybe you’ve purchased travel insurance. With everything from accident insurance to workers comp, insurance coverage—while not quite getting you from A-Z—is fairly all-encompassing. 

That makes sense. Insurance products are designed to protect against different types of risk, and there’s a whole lot of risk in this world. 

It’s important to distinguish between lines of authority, which are generally associated to state language about what kind of license, continuing education, and regulations you have to keep track of, versus a line of business, which is usually how a carrier or agency thinks of insurance types. For instance, casualty insurance is an LOA that may include lines of business such as auto insurance, workers comp, liability insurance, and theft insurance.  

For insurance carriers, agencies, and MGAs, managing lines of authority at scale can become operationally complex. Compliance teams must verify that every producer maintains the appropriate resident and nonresident licenses, appointments, and LOAs before selling insurance products in a given state. Otherwise, you’re putting your business at an increased risk of regulatory action, or even losing your insurance license.

Why do LOAs matter for insurance compliance?

Lines of authority are foundational to insurance producer licensing compliance because they determine which insurance products a producer can legally sell in each state. LOAs are critical when it comes to producer licensing.

Producers need to be properly licensed to sell insurance products. That’s because producers play an important role in advising consumers on which insurance products are best suited to meet their needs. As such, it makes sense that they need to go through rigorous training and exams to prove they know their stuff when it comes to the range of insurance products available in the market. 

Because insurance licensing requirements vary by state, agencies and carriers must continuously track producer LOAs, appointments, renewals, and continuing education requirements to remain compliant. With so many different insurance products available, insurance producers could find themselves studying, training, and taking exams till the end of time. That’s why states group similar lines of business and insurance products together in an effort to consolidate licensing requirements.

Instead of needing to complete training and exams for auto, workers comp, liability, and theft, producers can take an all-encompassing casualty insurance training and exam, which covers key concepts for these like-products.

Please note: While this is generally true, there are some specific insurance products that have their own licensing requirements within a given LOA. Flood insurance, for example, is a casualty or personal lines product with very specific certification requirements separate from that of the broader LOA.

What are the major insurance LOAs? 

Though there are rather niche LOAs that vary state-by-state, there are a couple of major lines that are the bread and butter of the insurance industry.

There are six major (or general) LOAs as defined by the National Association of Insurance Commissioners (NAIC) in the Uniform Licensing Standards (ULS). The NAIC presents these six LOAs and their definitions as follows: 

1. Life

Insurance coverage on human lives, including benefits of endowment and annuities, and may include benefits in the event of death or dismemberment by accident and benefits for disability income.

2. Accident and health or sickness

Insurance coverage for sickness, bodily injury or accidental death, and may include benefits for disability income. This LOA also gives insurance producers the ability to sell Medicare and long-term care insurance policies. 

3. Property

Insurance coverage for the direct or consequential loss or damage to property of every kind.

4. Casualty

Insurance coverage against legal liability, including that for death, injury or disability, or damage to real or personal property. A casualty line of authority may include auto, workers’ compensation, liability, and theft insurance products, depending on state regulatory definitions.

5. Variable life and variable annuity 

Insurance coverage provided under variable life insurance contracts and variable annuities. 

6. Personal lines

Property/casualty (P/C) insurance coverage sold to individuals and families for primarily noncommercial purposes.

Most states have adopted these definitions of the six LOAs, but some choose to further bundle insurance products. For instance, it isn’t uncommon for property and casualty LOAs to be combined as property and casualty insurance. 

What are limited LOAs?

Whereas major line LOAs cover a broad spectrum of standard insurance products, limited lines licenses apply to specialized insurance products and often have unique state-specific compliance and training requirements for agencies and carriers.

While there are over 50 different types of limited lines licenses offered across the United States, the ULS restricts each state to no more than nine limited lines, of which four must include the following core limited lines:

1. Car rental insurance
2. Credit insurance
3. Crop insurance
4. Travel insurance 

On top of the core limited lines, states may include non-core limited lines licenses such as title insurance, pet insurance, legal expense insurance, self-storage insurance, funeral or burial insurance, and many, many more. 

Since these lines are more narrowly focused, they typically don’t have quite so rigorous training requirements. In some cases, insurance producers who hold a general lines license won’t need additional licensing to sell, solicit, or negotiate a limited lines product. But remember: There isn’t much uniformity between states when it comes to licensing requirements for limited lines. So always be sure to check with your state department of insurance website to confirm compliance. 

Knowing the difference between lines of authority, lines of business, and license classes, as well as what states recognize which, can be tedious. Since insurance regulations differ significantly across jurisdictions, insurance organizations need accurate, up-to-date compliance data to manage producer licensing and avoid regulatory risk. 

Modern insurance compliance technology helps agencies and carriers automate producer licensing workflows, monitor state regulatory changes, and maintain accurate producer data across distribution channels.

LOA FAQs

Does the NAIC have a model act to create uniformity around LOAs?

Yes, the Producer Licensing Model Act #218 establishes uniform definitions regarding LOAs that can be adopted by states.

I’ve seen personal lines licenses listed as both major lines and limited lines, which is it?

A lovely quirk of insurance, personal lines can be treated as both a major line and a limited line. While the NAIC considers personal lines as one of the six major lines, states sometimes treat personal lines as a limited line in terms of licensing requirements.

What is a line of authority (LOA) in insurance? 

A line of authority (LOA) is a subject area or type of insurance that a licensed producer is authorized to sell. LOAs are established by state regulators to group similar insurance products together for licensing, continuing education, and compliance purposes.

What are the six major lines of authority in insurance? 

The six major LOAs as defined by the NAIC are: Life; Accident and Health or Sickness; Property; Casualty; Variable Life and Variable Annuity; and Personal Lines. Most states have adopted these definitions, though some bundle categories like property and casualty together.

What is the difference between a line of authority and a line of business?

A line of authority is a regulatory licensing classification defined by the state that determines what types of insurance a producer is licensed to sell. A line of business is how carriers and agencies categorize insurance products internally and often roles up to a line of authority. For example, casualty is an LOA that can encompass lines of business like auto, workers’ comp, liability, and theft.

What are limited lines of authority in insurance licensing? 

Limited lines licenses apply to specialized, narrowly defined insurance products such as car rental insurance, travel insurance, crop insurance, and credit insurance. They typically have less rigorous training requirements than major line LOAs, but licensing requirements vary significantly by state.

How do insurance agencies and carriers manage producer lines of authority compliance? 

Managing LOA compliance at scale requires tracking each producer’s resident and nonresident licenses, appointments, renewals, and continuing education requirements across every state they operate in. Modern compliance automation platforms like AgentSync help agencies and carriers automate these workflows, monitor regulatory changes, and maintain accurate producer data.
