A certificate of insurance (COI) also known as a letter of insurance coverage is proof of protection, providing important policy details. It’s requested by third parties to verify an individual or organization’s assurance.

It is often requested by clients, vendors, or landlords, to verify that an individual or organization has safeguards.

The COI typically includes details such as the insured’s name, the type of coverage, limits, effective dates, and the name and contact information of the provider. It acts as evidence of property insurance or any other type of coverage mentioned in the certificate.
