What to Look For When Comparing Auto Insurance Companies

What are the top insurance companies in the U.S. doing to earn your business? Beyond looking at insurance companies ranked by size and monthly rates, there are a few more things to look for when reviewing car insurance companies.

For example, start checking customer satisfaction reviews on your favorite insurers. Make sure the car insurance company you select has a great track record of keeping customers happy and offers different insurance options.

You might be wondering, where can I find unbiased reviews of auto insurance companies? Fortunately, we’ve compiled a brief list of questions to consider during your research to help you shop smarter:

• Does the company have an excellent customer service reputation? Even the major auto insurance companies in the United States should earn your trust through great customer service. When reading reviews or ratings for car insurance companies, consider the company’s reputation for customer service.
• Does the company pay claims promptly and without issue? When you’re comparing the major U.S. insurance companies, see how long the claims process usually takes. Great insurance companies will pay claims promptly and not hassle their customers when it comes to paying out on policies.
• Is the car insurance company more concerned with its bottom line than the customer’s well-being? The leading auto insurance companies should also make you feel valued. You’ll have to communicate with your carrier, so ask yourself, does the insurance company show concern if you’re involved in an accident and treat the customer with respect?

Automobile accidents are stressful enough. The best insurance companies will be less concerned about their bottom line and more concerned with you.

The Highest-Rated Auto Insurance Companies

Who is often the top-rated auto insurance company in the U.S. for customer and claims satisfaction? Incidentally, State Farm is usually at the top of the J.D. Power annual survey. It is the only major auto insurance company in the U.S. to rank in the top five for claims satisfaction, partially due to its easy-to-navigate claims page online.

For example, State Farm asks questions that quickly prompt policyholders through the process and provides resources for non-customers to handle claims quickly.

 

State Farm customers report that they are very satisfied with the customer service provided by this company. Allstate and American Family also appear in the top ten auto insurance companies for claim satisfaction, but State Farm usually ranks high on all metrics in most customer service satisfaction reviews.
