Choosing a large, well-known insurance company could come with several benefits. Along with nationwide availability, expanded policy options and discount opportunities, the largest auto insurance companies also tend to regularly score highly in customer service experience and rate well in financial strength by third-party agencies. Having access to this information can be helpful when narrowing down the options while shopping for auto insurance.
Bankrate reviewed the most recent Insurance Information Institute (Triple-I) analysis of data from National Association of Insurance Commissioners (NAIC) to determine the largest car insurance carriers by market share.

Why should I pick a large car insurance company?
Purchasing a policy from a large auto insurer could have multiple benefits since major carriers tend to have vast resources to offer. One factor to consider when choosing the right car insurance company for you is a company’s stability.
With more premiums written, a large insurance company is often more financially stable than a smaller, regional carrier that is more limited in its scope. While some national carriers may have higher rates than regional insurers, they may also be able to offer more discounts and savings programs that policyholders can use to lower their costs.
Large auto insurance companies also tend to offer extended customer service hours, sometimes even offering 24/7 instant support by phone and chat. Smaller car insurance companies may not have the resources to maintain these extended levels of customer support.
When it comes to whether a large insurance company or small company is better, it depends on your needs and what you want in an auto insurer.
