By the time Emily got the call, it was already too late.
The venue manager was furious. A stagehand had tripped over a lighting rig during setup for her event planning business. He was injured, and the venue was demanding proof that her company was insured — or she’d be held personally liable.
Emily scrambled through her email. She had insurance, but never thought about needing a Certificate of Insurance (COI) until someone asked for it.
What Is a Certificate of Insurance (COI)?
A Certificate of Insurance is a document issued by an insurance company that proves an individual or business has insurance coverage. It summarizes the policy details — such as:
- Types of coverage (e.g., general liability, workers’ comp)
- Policy limits
- Effective dates
- Insurer and policyholder names
It’s not the policy itself, but a proof of coverage — often used in business transactions.
Why Is a COI So Important?
Let’s go back to Emily. If she had her COI ready to go:
- The venue would have confirmed her general liability insurance in seconds.
- The injured worker’s medical bills would have been processed through the policy.
- Her business reputation — and finances — would have remained intact.
In business, having insurance is not enough. You must be able to prove it.
Who Needs a Certificate of Insurance?
If you’re in any of the following roles, you likely need to request or provide a COI regularly:
- Contractors or subcontractors
- Freelancers working on-site
- Event planners
- Landlords and tenants
- Vendors at markets or fairs
- Small business owners hiring third parties
Many U.S. businesses won’t work with another company or contractor unless they have a valid COI.
What Does a COI Include?
A standard ACORD 25 form (the most common COI in the U.S.) typically contains:
| Section | What’s Included |
|---|---|
| Insured | Name and address of the policyholder |
| Insurer(s) | Names of the insurance companies |
| Coverage Types | General liability, auto, umbrella, workers’ comp |
| Limits | Maximum amounts the insurer will pay |
| Effective Dates | Start and end of coverage |
| Certificate Holder | The third party requesting proof of insurance |
| Description of Operations | Custom details for specific contracts |
How to Get a Certificate of Insurance
If you’re a business owner or freelancer:
- Contact your insurance agent or provider
Ask them to issue a COI for the party requesting it. - Provide certificate holder details
Include the name, company, and address of the person requesting the COI. - Specify any required endorsements
Some contracts may require additional insured status or waivers of subrogation. - Receive and send the document
The COI is usually emailed in PDF format, and you forward it to the requestor.
💡 Pro Tip: If you work with multiple clients, ask your insurer about setting up a self-service COI portal.
What’s the Difference Between a COI and an Insurance Policy?
| Feature | Certificate of Insurance | Insurance Policy |
|---|---|---|
| Purpose | Proof of coverage | Legal contract |
| Length | 1–2 pages | Dozens of pages |
| Customizable? | Yes (for certificate holders) | No |
| Legally Binding? | No | Yes |
Think of a COI like a driver’s license — it shows you’re legally allowed to drive, but it’s not the car or the full contract.
What Happens If You Don’t Have One?
Emily’s story is just one of many. Without a COI, you could face:
- Lost business opportunities
Clients may drop you if you can’t provide proof of insurance. - Legal liability
You could be personally sued if something goes wrong and you can’t prove you’re covered. - Breach of contract
Many business agreements require a COI — and failing to provide it may void the contract.
Real-Life Example: The $2 Million Mistake
In 2021, a subcontractor in Texas started work on a commercial renovation. The general contractor forgot to verify his COI. Weeks later, a pipe burst — causing $2 million in water damage.
Turns out, the subcontractor’s insurance had lapsed.
Guess who paid the bill? The general contractor — all because he didn’t ask for a COI.
How Long Is a Certificate of Insurance Valid?
Most COIs are valid for the duration of the insurance policy, typically 12 months. However, you should always check the “Effective Dates” on the certificate.
Some companies require updated COIs every year, especially for ongoing contracts.
Don’t Wait to Be Asked
Just like Emily, many professionals don’t think about a Certificate of Insurance until it’s too late. But in the world of business, it’s a must-have.
Whether you’re a contractor, vendor, or event planner, having your COI ready shows you’re legitimate, professional, and protected. It could be the difference between landing your next job — or losing it.

- A Certificate of Insurance (COI) proves you have active coverage.
- It’s essential in business relationships, especially in high-risk industries.
