List of Auto Insurance Companies

Shopping for auto insurance can be a daunting task. There are many choices of insurance companies, purchase options and coverage options, all with various price points. For example:
Company choices - Over 2500 companies offer auto insurance in the United States. Not all companies can offer all of their plans in every state.
Purchase options - Some insurance companies sell their auto insurance through independent agents and others sell directly through their own agents, by phone, by mail and over the internet.
Coverage options - Most insurancecompanies offer similar types of insurance; however, the amount of coverage and the details of the coverage can vary between policies.
Price points - The actual price of a specific type of insurance varies between insurance companies and, in fact, can vary between policyholders purchasing insurance from the same insurance company.


You should also compare the ratings of the insurance companies. By making this comparison you will know how other insurers feel about the company's service and whether the company has the financial strength to pay your claim.
Auto Insurance Ratings

Financial ratings from independent companies such as A.M. Best and Standard & Poor's are an overall measurement of a company's financial strength. The ratings are expressed as letter grades. These financial ratings are a big selling feature so the company will usually feature their rating in their sales materials.
