MetLife Auto and Home is the 14th largest auto insurance company in the United States and is a branch of the larger MetLife global company. MetLife is primarily known for its life insurance products, but its Auto and Home branch is one of the largest auto insurance companies in the U.S., selling auto policies in all 50 states. MetLife Auto and Home offers some unique discounts but it has received average reviews for customer service from independent rating companies. MetLife auto insurance can be a good add-on to consider for current MetLife home and life insurance customers with some of the multiple policy discounts offered.
