Check before you buy or file a complaint
Insurer groups sell through many separate companies, and each is licensed state by state. Look up the exact company on your policy in the NAIC Consumer Insurance Search for licensing, complaint and financial information, or contact your state insurance department. Independent financial strength ratings are published by agencies such as AM Best.
