This advisory material is relayed to insurance companies that subscribe to the ISO rating information. The lower the rating range, the lower the insurance costs can be for residents and business owners with participating insurance companies. According to the ISO, a listing of subscribing insurers is proprietary, therefore residents and business owners should contact their insurance carrier directly to see if they subscribe and if they provide any type of discount based on that rating.
