An additional insured is a person or organization that is covered by an insurance policy, in addition to whoever originally purchased the policy. Many insurance carriers will offer blanket coverage to a policy that covers landlords, lessors, etc. However, some organizations require the specific entity to be added. If your contract requires that you list a company as your additional insured, make sure to include the language they used on your Certificate of Insurance.
