What is the Insurance Services Office?

A Brief History of the Insurance Services Office

The ISO was established in 1971 as a rating and advisory body for the property and liability insurance sector. Initially, it offered actuarial and statistical services as well as programs made to assist insurance companies in adhering to state regulations.

The company is currently a division of Verisk Analytics Incorporated, a conglomerate with operations in every state in the United States as well as 30 nations. These businesses also supply information to health insurance providers, mortgage lenders, and other companies.

It came about as a result of multiple companies’ databases merging. ISO started providing analytics services, such as underwriting analytics, actuarial data, and policy language, using this combined data.
