Certificate of insurance for an LLC: what it is and when you need one
A certificate of insurance is not the policy itself. It is the one-page proof people ask for when they want to know your LLC has active coverage.
The short version
A certificate of insurance, often shortened to COI, proves that your LLC has a business insurance policy in force. It usually lists the insured business name, insurer, policy number, policy type, limits, and effective dates. It may also show a certificate holder, additional insured status, or other wording a client or landlord requested.
An LLC commonly needs a COI when it signs a client contract, bids on a project, leases space, applies for a license, works as a contractor, hires subcontractors, or has to prove general liability, professional liability, workers' compensation, commercial auto, or property coverage. You get it from your insurance company, agent, broker, or online account after buying the policy.
The important part: a COI summarizes coverage. It does not rewrite the policy. If the contract requires exact wording, limits, endorsements, or additional insured status, confirm that with the carrier or agent before you send the certificate.
What a COI usually includes
The Hartford describes a COI as a summary of business insurance coverage. Insureon says it condenses key policy information into one page. In practice, most COIs include the same basic fields:
| Field | Why it matters |
|---|---|
| Named insured | The legal name should match the LLC name, not just the owner's personal name. |
| Insurance company | The client can see which insurer issued the coverage. |
| Policy type | Shows whether the proof is for general liability, workers' comp, auto, property, or another policy. |
| Policy number | Lets the certificate be tied back to a specific active policy. |
| Effective and expiration dates | Shows whether coverage is active during the job, lease, or contract period. |
| Limits | Shows the maximum coverage amounts shown on the certificate. |
| Certificate holder | Often the client, landlord, lender, marketplace, or project owner requesting proof. |
| Additional insured wording | May be needed if the other party requires more than proof that a policy exists. |
When an LLC gets asked for one
A COI usually shows up when someone else is taking a risk by working with your LLC. A client may want proof before allowing you on a job site. A landlord may require liability coverage before handing over keys. A marketplace, event venue, government buyer, general contractor, or professional license board may require proof before approving your business.
Hiscox gives a simple general liability example: if you bid on certain contracts, liability insurance could be a condition of the award, and a certificate of insurance can show that you meet the requirement. The Hartford gives similar examples for clients, contractors, leases, and landscaping bids.
Some requests are ordinary. "Please send your COI" is often just asking for proof of active coverage. Other requests are more specific. They may ask for a certain limit, waiver of subrogation, additional insured status, primary and noncontributory wording, completed operations coverage, or a specific description of operations. Do not guess on those. Send the requirement to your agent or insurer.
How to get a certificate
First, the LLC needs an active policy. A certificate is proof of insurance; it is not a substitute for buying insurance. Insureon says most certificates are available online after the policy is issued. The Hartford says policyholders can request one through an online account, through agents or brokers, or by phone, and that many requests are processed instantly.
If the LLC already has coverage, log in to the carrier or agency portal and look for certificates, proof of insurance, documents, or COI requests. If the request involves extra wording, use the request form or contact support instead of downloading a generic certificate and hoping it is enough.
Certificate holder is not always additional insured
This is the place where owners get tripped up. A certificate holder is usually the person or company receiving proof of insurance. Additional insured status can give that person or company certain rights under the policy, depending on the endorsement and policy language.
The Hartford warns that adding a client as a certificate holder does not mean the client has legal rights on your liability coverage. To extend liability coverage, the client has to be added as an additional insured on the policy. If a contract asks for additional insured status, a plain COI may not satisfy it.
What to check before sending it
- Does the named insured match the LLC's legal name?
- Are the policy dates active through the job, lease, or contract period?
- Do the limits match the written requirement?
- Does the certificate show the right policy type, such as general liability or workers' comp?
- Does the certificate holder name and address match what the requester gave you?
- If additional insured wording is required, does the carrier confirm it is actually endorsed?
Bottom line
A certificate of insurance is a normal operating document for many LLCs. It helps prove that the business has coverage without sending the full policy. But it is only as useful as the policy behind it.
If a client, landlord, or license board gives you exact insurance requirements, do not treat the COI as a paperwork formality. Compare the requirement to your policy, and ask the carrier or a licensed agent before assuming the certificate satisfies the contract.
