Certificate of Insurance (COI) - What It Is, Who Needs One, and How to Get It Fast

What Is a Certificate of Insurance?

A certificate of insurance (COI) is a one-page document that proves you have active insurance coverage. That is all it is. It is not a policy. It does not change your coverage. It does not add or remove anything from your insurance program.

Think of it like a receipt. Your insurance policy is the actual product. The certificate is proof you bought it.

A COI lists your coverage types, policy limits, policy numbers, effective dates, and the name of your insurance carrier. When someone asks for your "proof of insurance" or your "insurance certificate," they are asking for this document.

The standard format is the ACORD 25 form. Nearly every certificate you have seen or will see uses this format. It is the industry standard across all 50 states.

Why You Keep Getting Asked for Certificates

Every business relationship that involves risk eventually requires proof of insurance. The list of people who will ask you for a certificate is long, and it keeps growing.

• General contractors require a COI before you step on the jobsite. No certificate, no work. Most GCs also require specific endorsements (more on that below).
• Project owners require certificates from every contractor on their project, often with higher limits than your standard policy carries.
• Landlords require a COI before you sign a commercial lease. They want to know your business has liability coverage if something happens in their building.
• Clients and customers require them before you start a project. This is becoming standard in every service industry, not just construction.
• Government agencies require certificates for permits, licenses, and public contracts.
• Banks and lenders require them for loan closings, equipment financing, and lines of credit.
• Vendors and suppliers may require them before extending credit or delivering materials to your jobsite.

The bottom line: if you do business with other businesses, you need certificates. It is the cost of doing business in every commercial industry.

What Is on a Certificate of Insurance?

The ACORD 25 form is organized into several sections. Here is what each one means.

• Named insured: Your company name and address exactly as it appears on your policy.
• Producer: Your insurance agency - the company that placed your coverage. For Grit clients, this is Grit Insurance Group.
• Insurer(s): The actual insurance carrier(s) underwriting your policies. You may have different carriers for different lines of coverage.
• Coverage types and limits: Each active policy is listed with its coverage type and limit. Common lines include general liability, commercial auto, workers compensation, and umbrella/excess liability.
• Policy numbers and dates: Every policy listed shows its number and effective/expiration dates.
• Certificate holder: The person or company who requested the certificate. Their name and address appear in a dedicated box at the bottom.
• Description of operations: A free-text field where specific project details, endorsement language, or contractual requirements are noted.
• Cancellation provision: Standard language about what happens if a listed policy is canceled.

The form also has checkboxes and fields for additional insured status, waiver of subrogation, and primary/non-contributory language. These matter more than most people realize.

Additional Insured vs Certificate Holder - the Difference That Matters

This is where most confusion happens, and it is where mistakes cost people money.

A certificate holder just receives the certificate as proof that your coverage exists. That is it. They get a piece of paper. They do not get any coverage rights under your policy. If something goes wrong on your project, the certificate holder has no claim against your insurance just because they hold the certificate.

An additional insured is a completely different thing. When someone is added as an additional insured on your policy, they get actual coverage under your policy for claims arising from your work. If a GC is named as additional insured and gets sued because of something you did on their jobsite, your GL policy responds to defend them.

This is what general contractors actually need, and it is what most subcontract agreements require. A certificate alone does not make someone additional insured. The endorsement must be added to the policy itself. The certificate then reflects that the endorsement exists.

Getting this wrong means the GC thinks they are covered when they are not. That is a problem that shows up at the worst possible time - when there is a claim.

Other Endorsements That Show Up on Certificates

Beyond additional insured, you will regularly see these endorsement requirements on certificate requests:

• Waiver of subrogation: Your carrier agrees not to go after the certificate holder to recover claim payments. Many GC contracts require this.
• Primary and non-contributory: Your policy pays first on a claim before the other party's policy kicks in. This protects the GC's own insurance program from being tapped first.
• Per-project aggregate: Your aggregate limit applies per project instead of across all projects for the policy year. Required on larger commercial and public jobs.

Your agent should know which endorsements your policies already include and which ones need to be added. Many modern GL policies include blanket additional insured and blanket waiver of subrogation at no extra charge. If yours does not, it may be time for a coverage review.

How Fast Can You Get a Certificate?

This should not be a multi-day process. If you are waiting two or three days for your agent to issue a certificate, that is a service problem - not an insurance problem.

At Grit, we issue same-day certificates with the correct endorsements. We handle the additional insured language, waivers of subrogation, and primary/non-contributory requirements. When your GC sends a certificate request at 8 AM, you should have it in their inbox before lunch.

You should not be losing jobs or delaying starts because of paperwork. If that is happening, your agency is the bottleneck.

Frequently Asked Questions

How much does a certificate of insurance cost?

The certificate itself is free. It is just a document proving your coverage exists. Some carriers charge a small fee ($25-$50) for adding an additional insured endorsement to the policy, but many include blanket additional insured in their standard policy at no extra charge. Ask your agent whether your policy includes blanket endorsements.

What is the difference between a certificate of insurance and proof of insurance?

They are the same thing. "Certificate of insurance" is the formal industry term. "Proof of insurance" is the common language version. The ACORD 25 form is the standard certificate format used across the insurance industry. If someone asks for proof of insurance, send them a certificate.

How long does a certificate of insurance last?

A certificate reflects the active policy period. When the policy renews, a new certificate is issued. Most certificates are valid for one year, matching the policy term. Some project-specific certificates are required for the duration of the contract, and your agent will reissue them at each renewal until the project is complete.

Can I get a certificate of insurance without a policy?

No. A certificate is proof of an existing policy. You must have active coverage in place before a certificate can be issued. If you need coverage and a certificate quickly, call Grit directly at (801) 505-5500. We can often get both done the same day.
