The Top 10 Largest Auto Insurance Companies

Hundreds of companies sell car insurance, but can you name the country’s largest auto insurance companies off the top of your head? If Allstate, Geico, Progressive and State Farm come to mind first, that makes sense: Together, these four companies make up over half of the personal auto insurance market in the U.S.

You’ve probably heard of the other companies rounding out the top 10, too.

Larger insurance companies can have advantages over smaller companies, such as greater financial strength and stability, a wider network of agents and claims adjusters, 24-hour customer service, and better apps and websites.

But there’s more to an insurer than size. Here’s additional information about each of the largest auto insurance companies, including the latest available consumer satisfaction ratings from J.D. Power and consumer complaint data from the National Association of Insurance Commissioners.

State Farm, the country’s largest car insurance company, offers policies nationwide except in Massachusetts and Rhode Island. Coverage is sold exclusively by captive agents, meaning they sell only State Farm products, but you can get a quote and manage policies online. There’s also a mobile app that lets you get quotes, submit claims and view your insurance card.

State Farm offers many other types of policies, including renters, business, home, boat, off-road vehicle and commercial auto insurance. In some cases, discounts are available for drivers who buy more than one type of policy.

Geico primarily sells auto insurance directly to customers online or by phone, but agents are available in some states. You can buy and manage policies through Geico’s website or mobile app, and voice assistance is available through the app or via Amazon’s Alexa. Policies are available in all 50 states and Washington, D.C.

In addition to auto insurance, Geico offers umbrella liability coverage and insures motorcycles and all-terrain vehicles. Auto insurance discounts are available to customers who buy other policies, such as home insurance, from companies that have partnerships with Geico.

Travelers also sells umbrella policies and insurance for homes, condos, boats, renters, landlords, businesses, weddings and jewelry. In some cases, discounts are available if you buy more than one type of coverage from Travelers.

American Family ranks as the 10th largest auto insurance company in the nation even though it offers policies in fewer than half of U.S. states. Coverage is available mostly in the West and Midwest. You can find an agent and get a quote at the American Family website. There’s also a mobile app for filing claims, managing coverage and getting help.

Size isn’t the only reason to choose an auto insurance company. In ranking the best car insurance companies, NerdWallet also examines customer service and claims satisfaction scores from J.D. Power and Consumer Reports, along with complaint data from the National Association of Insurance Commissioners.

Here’s how the largest auto insurance companies stack up in NerdWallet’s 2019 ranking of 24 insurers. USAA isn’t eligible for ranking because it is available only to military members, veterans and their families.

Although Nationwide scored highest among the 10 largest companies, it ranked eighth out of 24 in NerdWallet’s overall analysis — which means the top seven spots went to smaller insurers.
