A Certificate of Insurance (COI) is a summarized proof of an insurance policy. Issued by an insurance carrier or broker, it confirms that a valid policy exists. The COI condenses essential policy details into a one-page document for quick verification.
Businesses, contractors, and clients use COIs to confirm insurance coverage before signing contracts, starting projects, or renting equipment. It provides a fast reference without reading the full policy.
What Information Does a COI Include?
A standard COI typically shows:
| Field | Description |
|---|---|
| Policyholder | Name of the insured company or individual |
| Insurance Carrier | Licensed insurer providing coverage |
| Policy Number | Unique identifier for the insurance policy |
| Coverage Types | General liability, workers’ compensation, property, commercial auto |
| Coverage Limits | Maximum payout amounts per type of coverage |
| Deductibles | Amount paid by the insured before coverage applies |
| Effective Date | Start date of coverage |
| Expiration Date | End date of coverage |
| Additional Insureds | Other parties included for protection |
| Insurer Contact | Phone or email for verification |
Some COIs also include endorsements, exclusions, or special conditions depending on policy type.
How Does a Certificate of Insurance Work?
A COI serves as instant proof of insurance in high-liability situations. Examples:
-
A contractor bidding for a construction project provides a COI showing coverage for property damage and injuries.
-
An event organizer requires COIs from vendors before booth setup.
-
A commercial property owner asks for a COI before leasing space to ensure tenant insurance.
Without a COI, businesses often cannot secure contracts, as clients avoid hiring uninsured vendors.
Why Businesses and Contractors Need a COI
-
Proof of Insurance – Confirms that coverage is active, protecting clients from liability costs.
-
Risk Management – Helps clients verify that insurance meets project or contractual requirements.
-
Quick Reference – Provides essential policy details in under a minute, avoiding full-policy review.
When Is a COI Required?
Common scenarios include:
-
Hiring subcontractors for construction
-
Renting equipment for a project
-
Signing service contracts with corporate clients
-
Hosting events at a rented venue
-
Transporting goods for third parties
In all cases, the COI ensures financial protection against injuries, property damage, or negligence.
Is a COI the Same as an Insurance Policy?
No. A COI summarizes the policy but is not the contract itself. It reflects coverage at the issue date. If the policy is canceled or changed afterward, the COI does not automatically update, so clients often request the most recent certificate before work begins.
How to Obtain a COI
If You Are the Policyholder:
-
Contact your insurance agent or broker.
-
Provide details of the requesting party if they need to be listed as additional insured.
-
Request a new COI whenever coverage changes.
If You Are Hiring Someone:
-
Request the COI directly from the insurer, not just the contractor.
-
Verify that coverage types, limits, and dates match contract requirements.
-
Ensure coverage lasts through the entire project timeline.
Checklist for Verifying a COI
-
Confirm the policyholder’s name matches the company or individual you’re hiring.
-
Check the policy number for validity.
-
Ensure the insurer is licensed and reputable.
-
Verify coverage limits meet contractual obligations.
-
Confirm the policy expires after project completion.
-
Check that additional insureds are correctly listed.
Common Insurance Types on a COI
-
General Liability Insurance – Covers third-party injuries and property damage.
-
Workers’ Compensation – Protects employees and meets legal requirements.
-
Commercial Auto Insurance – Covers business vehicles used for work.
-
Professional Liability (Errors & Omissions) – Covers mistakes in services.

Why an Updated COI Is Crucial
Insurance coverage can change due to:
-
Non-payment of premiums
-
Changes in business operations
-
Policy cancellations or renewals
Request a COI close to the project start date to ensure accuracy.
