What Is an ACORD Insurance Certificate? Types & Uses

If you've ever been handed a document with "ACORD" printed across the top and felt a wave of confusion, you're not alone. The ACORD certificate of insurance is one of those forms that looks far more complicated than it actually is. Once you understand what it does and why it exists, the whole thing clicks into place pretty fast. Let's walk through it.

An ACORD certificate of insurance is a one-page document that summarizes an insurance policy to prove that coverage exists. That's it. It doesn't grant rights, and it doesn't replace the actual policy. It simply tells the person receiving it: "Yes, this business or contractor is covered, and here's what that coverage looks like."

ACORD stands for Association for Cooperative Operations Research and Development. The organization was founded in the 1970s with one goal: to create standardized forms across the insurance industry so that everyone, including insurers, businesses, and contractors, was working from the same playbook. Before ACORD, every insurance company had its own format, which made verifying coverage a slow, inconsistent mess.

One quick note on naming: "ACORD certificate of insurance," "COI," and "certificate of liability insurance" are often used interchangeably. They refer to the same document. If someone asks you for a COI, an ACORD form, or proof of insurance, they're all asking for the same thing.

‍Is an ACORD Certificate the Same as Proof of Insurance?

Close, but not exactly. An ACORD certificate shows that coverage exists and summarizes the key details, but it doesn't give the certificate holder any rights under the insurance policy itself. Think of it like a receipt summary rather than the full contract.

This distinction matters. The certificate reflects the policy at the time it was issued. If the insured later cancels or changes their coverage, the certificate doesn't automatically update. That gap between what a certificate says and what's actually in force is one of the most common sources of compliance headaches, and one of the main reasons ongoing tracking matters.

What's Actually on an ACORD Certificate?

The form is designed to pack a lot of useful information into a single page without overwhelming the reader. Here's what you'll find:

• Insured and producer info: The top of the form identifies the insured (the business or contractor holding the policy) and the agent or broker who issued it.
• Coverage types and policy details: The middle of the form lists the types of coverage in place. Common examples are general liability, workers’ compensation, auto liability, and umbrella/excess liability insurance, along with each policy number, effective date, and expiration date.
• Coverage limits: Next to each coverage type, you'll see the policy limits, the maximum the insurance provider will pay per occurrence or in aggregate. This is where you confirm whether the liability coverage meets your requirements.
• Certificate holder details: The bottom of the form identifies who's receiving the certificate. This is typically the business or organization requesting proof of insurance. One common point of confusion: the certificate holder and an additional insured are not the same thing. Being listed as a certificate holder just means you received the document. Being named as an additional insured on the underlying policy gives you actual protection under that policy, which is a meaningful difference when a claim arises.

What Are the Main Types of ACORD Certificates?

There are several types of ACORD certificates, but most people will only encounter a few of them regularly.

ACORD 25 is by far the most common. It's the standard certificate of liability insurance used in most business relationships. You’ll often see it in the context ofonboarding third-party partners contractor compliance, and commercial agreements. When someone asks for a COI, they almost always mean an ACORD 25.

ACORD 27 and ACORD 28 are evidence of property insurance forms. ACORD 27 covers personal property; ACORD 28 is the commercial version. These come up most often in real estate transactions and lending scenarios where a lender needs to confirm that a business insurance policy covers a specific asset.

ACORD 101 is a supplemental form, an Additional Remarks Schedule, used when the standard form runs out of space. If a policy has endorsements or unusual conditions that don't fit the main form, the ACORD 101 captures the overflow.

For most people managing contractor or vendor relationships, ACORD 25 is the one that matters.

When Should You Request an ACORD Certificate?

The short answer: before work begins and at every renewal. The longer answer involves a few specific scenarios, including the following:

• Onboarding a new contractor or third-party partner. Before any independent contractor sets foot on your property or starts a project, you should have a current COI on file that meets your coverage requirements.
• Renewing a service agreement. Policies expire. An ACORD certificate from two years ago doesn't confirm today's coverage. Build certificate renewal into your contract renewal process.
• Bidding on a construction project. Most general contractors and project owners require proof of liability insurance and workers’ compensation before awarding work. Having a current ACORD 25 ready keeps your bid process moving.
• Entering a commercial lease. Landlords routinely ask tenants (and tenants ask subtenants) to provide a COI naming them as an additional insured before the lease begins.

If you feel awkward asking for a COI, it's worth reframing: requesting one isn't confrontational, it's standard. Any established contractor or insurance company expects it. The businesses that push back on reasonable requests are often the ones worth paying closer attention to.
