What Is a Certificate of Insurance (COI)?

A Simple Explanation of a Certificate of Insurance

If someone asks you for a certificate of insurance (COI), it usually means they want proof that you have active coverage. This is common for contractors, small businesses, landlords, and vendors working with clients or property owners.



A COI is a document that summarizes key details about your insurance policy so others can verify your coverage quickly.
