GEICO, or Government Employees Insurance Company, is a prominent American auto insurance provider founded in 1936 by Leo and Lillian Goodwin. Initially focused on federal government employees and their families, GEICO has expanded its reach and is now the second largest auto insurer in the United States, covering approximately 30 million vehicles and 18 million auto policies.

The company operates under a direct-to-consumer sales model, which began in the 1990s, allowing it to reduce costs and offer competitive rates. GEICO employs around 40,000 people and provides 24/7 customer service for claims and support. While primarily known for auto insurance, it has also offered life insurance and loan products in the past. GEICO is recognized for its innovative advertising campaigns featuring the GEICO Gecko and the GEICO Caveman, which have significantly enhanced its brand visibility.
