There are several benefits to choosing a large car insurance company for your auto insurance policy. There’s often extended customer service, nationwide availability and expansive discount programs. Plus, with national advertising campaigns, it’s pretty hard to miss providers like State Farm, Allstate and Geico, who are known for their catchy slogans or creative mascots. While smaller companies may be able to deliver personalized service, the options for coverage and resources often tend to be limited.

To determine the largest market share of each car insurance carrier, we look to the most recent reporting from the National Association of Insurance Commissioners (NAIC) for annual market share. We also consider ratings from industry experts, such as J.D. Power for customer satisfaction and AM Best, which judges financial stability. Financial reliability is critical because it signals how efficient and reliable a company will be when it comes to claims processing and payouts.

Why should I pick a large insurance company?

There are a few factors to consider that can help you find the right car insurance company for your needs. The benefits of a large insurance company are many since they have vast resources that to offer.

With more premiums written, a large insurance company is often more financially reliable and secure than a smaller, regional provider that is more limited in its scope. Premiums may be a little more expensive to pay for those national ad campaigns, but there are typically more discounts and savings programs that policyholders can use to lower those premiums.

Large auto insurance companies also tend to offer extended customer service hours, sometimes even offering 24/7 instant support by phone and chat. Smaller companies just don’t have the resources to maintain these extended levels of customer support. However, just because a company is available, it doesn’t mean that service will be instant. Larger companies often have much longer wait times than smaller providers.

When it comes to whether a large insurance company or small company is better, it all depends on you and what you want in an insurance provider.
