If you’ve ever worked with a contractor, freelancer, landlord, or business partner, you may have been asked to provide a Certificate of Insurance (COI).
A COI is a simple document that proves you have an active insurance policy. It gives others a quick summary of your insurance coverage without sharing your entire policy.
Understanding what a Certificate of Insurance is and how it works can help you respond confidently when someone requests one.

What Is a Certificate of Insurance (COI)?
A Certificate of Insurance (COI) is a document issued by an insurance company or insurance agent that summarizes the main details of an insurance policy.
It serves as proof that insurance coverage is in place on the date the certificate is issued.
A COI is not the insurance policy itself. It only provides a summary of the coverage.
What Information Is Included in a COI?
The exact information may vary, but a Certificate of Insurance commonly includes:
- Name of the insured person or business.
- Insurance company name.
- Policy number.
- Types of insurance coverage.
- Coverage limits.
- Policy effective date.
- Policy expiration date.
- Certificate holder’s name, if applicable.
This information allows others to confirm that the required insurance is active.
Why Is a Certificate of Insurance Important?
Many businesses and organizations request a COI before working with another company or individual.
A Certificate of Insurance helps:
- Show that insurance coverage is active.
- Confirm the type of insurance carried.
- Verify coverage limits.
- Reduce financial risk for business partners.
- Meet contract requirements.
Having a COI ready can make business transactions smoother.
Who Might Need a Certificate of Insurance?
A COI is commonly requested from:
- Contractors.
- Construction companies.
- Freelancers.
- Small business owners.
- Consultants.
- Event vendors.
- Property management companies.
Some clients require a COI before allowing work to begin.
Is a Certificate of Insurance the Same as an Insurance Policy?
No.
A Certificate of Insurance is only a summary.
The full insurance policy contains complete information, including:
- Coverage details.
- Exclusions.
- Policy conditions.
- Endorsements.
- Deductibles.
The COI simply confirms that insurance exists and provides an overview of the policy.
How Can You Get a Certificate of Insurance?
If you need a COI, you can usually request one from:
- Your insurance company.
- Your insurance agent.
- Your insurance broker.
Many insurance companies also allow customers to download a Certificate of Insurance through their online account or mobile app.
How Long Is a Certificate of Insurance Valid?
A COI reflects your insurance coverage on the date it is issued.
However, if your insurance policy expires or is canceled, the certificate no longer proves that active coverage exists.
Because of this, businesses often request an updated COI when policies renew.
