A certificate of insurance (COI) is a short document, usually one or two pages, that summarizes the business insurance policies you carry. A client, landlord or event organizer asks for it as proof that you have coverage before you start work. It is a snapshot, not the policy itself, and it typically says it does not change or extend what the policy covers.
Key takeaways
- A COI summarizes your coverage: insurer, policy numbers, policy dates, coverage types and limits.
- Your agent or insurer usually issues certificates, often quickly and at no extra charge, though practices vary.
- Standard certificates generally state that they do not amend, extend or alter the coverage in the policy. The policy wording is what controls.
- Being listed as a certificate holder is not the same as being an additional insured. That status usually requires an endorsement on the policy.
What a certificate of insurance shows
A COI lists who is insured, which insurer wrote the policy, the policy number and the dates it is active. It also shows each type of coverage, such as general liability, commercial auto or workers' compensation, and the limits for each. In the US, many certificates use a standardized layout, so a client who requests one sees familiar boxes and sections.
Parts of a typical certificate
- Producer: the agent or broker who issued the certificate.
- Insured: the business that holds the policies.
- Insurers affording coverage: the companies behind each policy.
- Coverages: policy numbers, effective and expiration dates, and limits.
- Description of operations: a free-text box where special wording may appear, such as a project name or a reference to an endorsement.
- Certificate holder: the person or company receiving the certificate.
- Cancellation notice: a statement about how notice of cancellation is handled. Read it closely, as it often does not promise advance notice to the holder.
Who asks for one and why
Certificates come up whenever someone else wants confidence that your risks are insured. Common requesters include:
- Clients and general contractors hiring you for a project.
- Landlords and property managers leasing you space.
- Cities, festival organizers and markets issuing permits or booth spaces. A City of Sacramento vending document is an example of a local government spelling out its insurance and certificate rules.
- Lenders and franchisors reviewing your business.
The request is often tied to a clause in your contract. That clause may say which coverage types you need, minimum limits and whether the other party must be named on your policy. Review it early, ideally before you sign.
How to get a certificate
- Collect the requirements. Ask the requester for their written insurance requirements, including limits, coverage types and the exact name and address of the certificate holder.
- Contact your agent or insurer. Many insurers have an online portal or a service team that issues certificates. Send the requirement list and holder details.
- Check the draft. Make sure the legal names, dates, limits and policy numbers are right.
- Send it and track expiration. Provide the certificate to the requester and note when your policy renews, since a new certificate may be requested.
If you do not yet have the required coverage, say so before you promise anything. Our small business insurance guide covers the main policy types to consider.
Tip: Ask for certificates well before a start date. Some requesters reject certificates that are expired, marked "pending" or based on a binder, so timing can matter.
What a COI does not do
This is the part many business owners find surprising. Industry commentary on certificates notes that standard wording says the certificate does not amend, extend or alter coverage and that the policy terms control. Courts have often treated that language as meaning a certificate by itself does not create rights for the holder under the policy, though outcomes depend on the facts and the state.
In practice, that means a certificate alone does not:
- Give the holder any right to claim under your policy.
- Make the holder an additional insured.
- Guarantee the policy will remain active. A policy can be canceled or lapse after the certificate is issued.
- Prove that every kind of claim is covered. Exclusions and limits still apply.
Watch out: Certificates are meant to be accurate summaries, not promises. An agent should not issue a certificate that states coverage the policy does not actually provide. If a requirement cannot be met, ask your agent about options rather than relying on a certificate's wording.
Certificate holder vs. additional insured
Many requesters ask to be a certificate holder, which simply means they receive a copy. Others require additional insured status, which gives them protection under your liability policy for certain claims tied to your work. That status generally comes from an endorsement on the policy. We explain it in additional insured status explained.
| Feature | Certificate holder | Additional insured |
|---|---|---|
| What it is | The party receiving a copy of the certificate | A party added to your liability policy by endorsement |
| Rights under your policy | Generally none from the certificate itself | Defined by the endorsement wording |
| Where it comes from | The certificate | The policy endorsement |
| Typical use | Proof of coverage | Contract-required protection for the other party |
Common mistakes and how to avoid them
- Wrong legal name. A certificate that lists a different business name than your contract can be rejected.
- Insufficient limits. If a contract requires a higher limit than you carry, the certificate cannot fix that. Some businesses meet limits with an umbrella policy, covered in commercial umbrella insurance explained.
- Ignoring expirations. Policies renew yearly, and many contracts ask for updated certificates.
- Skipping the contract review. If wording such as waiver of subrogation or primary and noncontributory coverage is required, ask your agent whether your policy can provide it.
- Assuming it is a policy. If you are the one requesting certificates from subcontractors, consider asking for the endorsement pages as well as the certificate.
If you are the one collecting certificates
Hiring contractors or vendors? Collect certificates before work begins, check the expiration dates and make sure the coverage types match the risk. Where your contract requires it, ask for the relevant endorsements too. Consider having an attorney or your insurance advisor review your process, since contract and liability rules vary by state.
Frequently asked questions
How much does a certificate of insurance cost?
Many agents and insurers issue standard certificates without a separate fee, though practices vary. Fees may apply for special requests or custom wording. Ask your agent or insurer.
How long does it take to get a COI?
Often the same day or within a few business days, depending on whether the insurer has an online system and whether special wording is needed. Plan ahead if you have a deadline.
Does a COI mean I am covered?
It shows that coverage existed when the certificate was issued. Whether a particular claim is covered depends on the policy wording, limits, exclusions and whether the policy is still active.
Can I make my own certificate?
No. Certificates should be issued by your agent, broker or insurer. A certificate you create yourself could be treated as misrepresentation.
Is a COI the same as proof of car insurance?
No. Proof of auto insurance is an ID card or digital proof used for registration and traffic stops. A business certificate is a broader summary used in contracts. For the personal version, see proof of car insurance explained.
