Understanding the Meaning of COI in Insurance
COI stands for Certificate of Insurance. It is an official document issued by an insurance company or insurance agent that confirms an individual or business has active insurance coverage.
A COI is not the insurance policy itself. Instead, it is a summary document that shows:
- Type of insurance coverage
- Policy number
- Coverage limits
- Effective dates
- Name of the insured party
Think of a COI as proof that insurance exists and is currently active.
Why a COI Is Important in Business and Contracts
A COI plays a crucial role in risk management. Businesses request COIs to protect themselves from liability risks when working with contractors, vendors, or service providers.
For example:
- A landlord may require a COI before leasing commercial space.
- A construction company may request COIs from subcontractors.
- Event organizers may require vendors to provide a COI.
The purpose is simple: to confirm that if something goes wrong, there is insurance coverage available.
What Information Is Included in a COI
A standard Certificate of Insurance typically includes:
- Name of the insured individual or company
- Insurance company name
- Policy numbers
- Coverage types
- Coverage limits
- Policy effective and expiration dates
- Certificate holder name
Some COIs also list additional insureds, which means another party is protected under the policy.
