Certificate Of Insurance. A document issued by an insurance company/broker that is used to verify the existence of insurance coverage under specific conditions granted to listed individuals. (Investopedia)

certificate of insurance (COI). Document issued by an insurance company, it certifies that an insurance policy has been bought and shows an abstract of the most important provisions of the insurance contract. But it is not a substitute for the actual policy, and is normally a non-negotiable document-it cannot be assigned to a third party, and is unacceptable under the terms of a letter of credit and in making a claim.
