Allstate began by selling auto insurance through the Sears catalog and later built an agent network. The current company combines Allstate exclusive agents, National General independent agents, direct sales, and service businesses such as Allstate Protection Plans and Arity. The 2025 Form 10-K reports 211 million policies in force and ranks Allstate third in U.S. personal property and casualty insurance based on 2024 statutory direct premiums written. The company is headquartered in Northbrook, Illinois. Originally launched in Chicago, Illinois as a direct-mail auto insurance division of Sears, Roebuck & Co., the corporation eventually spun off to blanket America with its famous "Good Hands" agency network.
Allstate earns most of its revenue from insurance premiums, then invests funds held before claims are paid. In 2025, property and casualty premiums were $60.503 billion, accident and health premiums and contract charges were $946 million, other revenue was $2.955 billion, and net investment income was $3.449 billion. Allstate Protection distributes policies through exclusive agents, independent agents, contact centers, and online under the Allstate, National General, Direct Auto, and Answer Financial brands. Protection Services includes protection plans, roadside assistance, dealer services, identity protection, and Arity mobility analytics.
