What is the acronym for certificate of insurance?

A Certificate of Insurance (COI) is a standardized, single-page summary document issued by an insurance company to prove that active insurance coverage exists.

The most common format used across the United States is the ACORD 25 form (Certificate of Liability Insurance).

Main Sections of a Standard COI Format

A standard COI form is broken down into specific blocks or sections that provide an at-a-glance snapshot of a policy:

• Producer (Agent Info): Name, address, and contact details of the insurance agency or broker who issued the certificate.
• Insured: The legal name and address of the business or person who bought the insurance policy.
• Insurers Affording Coverage: A letter-coded table (Insr Ltr) identifying the specific insurance companies backing each policy.
• Type of Insurance & Policy Numbers: Lists coverages—such as General Liability, Automobile Liability, Excess/Umbrella Liability, and Workers' Compensation—along with their unique policy numbers.
• Effective and Expiration Dates: The exact start and end dates (MM/DD/YYYY) defining the active policy period.
• Policy Limits: The maximum dollar amounts the insurer will pay per occurrence and in the aggregate for claims (e.g., $1,000,000 general liability limits).
• Description of Operations / Locations / Vehicles: A text box noting specific job sites, projects, or special provisions, including notes on whether additional insured status applies.
• Certificate Holder: The name and address of the third party requesting proof of insurance (such as a property manager, general contractor, or city permit office).
• Authorized Representative: The signature or electronic stamp of the insurer's or agent's authorized representative, alongside cancellation provision terms.

What is a COI?

A COI is a one-page document issued by an insurance company or broker that summarizes an active insurance policy. It acts as a snapshot of your coverage. It typically includes:

• The policyholder’s name
• The types of coverage (such as general liability or workers' compensation)
• Policy limits and effective dates

COI vs. General Proof of Insurance

While a COI is proof of insurance, the broader term "proof of insurance" can refer to different documents depending on the context:

• Certificate of Insurance (COI): Used mainly for business, commercial leases, vendors, or contractors to show third parties that adequate liability coverage exists.
• Proof of Insurance (POI): A general term for any document verifying active coverage. For example, a personal auto insurance ID card is proof of insurance for driving, but it is not a COI.
• Not the Policy: Neither a COI nor a standard proof of insurance card replaces the actual insurance policy contract.
