ACORD 25 Explained: How to Read a Certificate of Insurance Line by Line

The ACORD 25 — formally the Certificate of Liability Insurance — is a one-page summary of someone's insurance program. General contractors collect them from every subcontractor. Landlords require them before handing over keys. Equipment rental houses ask for them before releasing machinery. If you spend any time in commercial contracting, construction, or property management, you read dozens of these each year.

Most people look at an ACORD 25 for about ten seconds: check the expiration dates, glance at the limits, file it. That is how coverage gaps and compliance problems get missed. Understanding every field on the form — what it means, what it does not mean, and where fraud and mistakes appear — is a skill that pays for itself the first time a questionable certificate crosses your desk.

This guide walks every section of the ACORD 25 from top to bottom, flags the five fields where mistakes most often hide, explains the legal significance of the disclaimer, and shows how to verify a certificate is real.

Section 1: Producer Information (Top Left)

The producer is the insurance broker or agency that issued the certificate. This block includes the agency name, address, phone, fax, and email. It is not the insurance company — it is the intermediary.

Why this matters: if something on the certificate looks wrong or you need to request a change, you contact the producer, not the carrier. If the certificate lists the wrong additional insured name, the wrong limits, or missing endorsements, the producer needs to reissue it. The carrier does not handle certificate requests directly.

For verification purposes, you can call the agency listed, give them the insured name and policy number, and confirm the cert reflects what is actually in force. Certificate fraud — fake certs showing higher limits or policies that do not exist — does occur. The easiest check is to call the producer on the certificate and verify.

Section 2: Insured (Top Right)

This is the named insured — the entity whose insurance program the certificate summarizes. It should match the legal name of the business exactly as it appears on the insurance policy.

This is the first field where mistakes hide. If the subcontractor's company is legally "Smith Contracting LLC" but the certificate says "Smith Contracting" or "Bob Smith," the coverage may not respond to a claim in the same way. Insurance policies are issued to named insureds, and the named insured on the cert must match the entity on the contract.

Common mismatches to watch for: DBA names instead of legal entity names; sole proprietor name instead of the company name; parent company name when a subsidiary is doing the work; outdated company name after a business restructuring or rebrand.

Section 3: The Coverages Table

Each row represents a coverage line. The ACORD 25 has designated rows for commercial general liability, automobile liability, umbrella/excess liability, workers compensation, and a freeform "other" row. Each row includes the insurer name, policy number, policy period, and limits.

Commercial General Liability (CGL)

The CGL row shows the insurer, policy number, effective and expiration dates, and the limits grid. The limits grid includes:

• Each Occurrence: The maximum the policy pays for any single claim. Standard is $1,000,000.
• Damage to Rented Premises: Covers fire damage to premises you rent. Standard is $100,000.
• Med Exp (Any One Person): Pays medical expenses for injured third parties regardless of fault. Typically $5,000 or $10,000. This is a small first-party payment, not a liability limit.
• Personal and Advertising Injury: Covers defamation, copyright infringement, false arrest, and similar offenses. Standard is $1,000,000.
• General Aggregate: The total the policy pays across all claims in a policy year. Standard is $2,000,000.
• Products and Completed Operations Aggregate: The total the policy pays for products and completed operations claims. Standard is $2,000,000. This limit covers claims arising from work you have already finished — the liability tail that persists after a project is complete.

The checkboxes on the CGL row — Claims-Made vs. Occurrence — are the second field where mistakes frequently hide. Occurrence policies cover incidents that happen during the policy period regardless of when the claim is filed. Claims-made policies cover claims filed during the policy period regardless of when the incident happened. For most construction work, you want an occurrence policy. If a certificate shows claims-made on a GL policy, ask why.

Automobile Liability

The auto row covers vehicles used in business operations. The key field is the Combined Single Limit — the maximum per accident for both bodily injury and property damage combined. Standard for commercial contracts is $1,000,000. The checkboxes indicate what vehicles are covered: Any Auto, All Owned Autos, Scheduled Autos, Hired Autos, and Non-Owned Autos. If only Scheduled Autos is checked, coverage is limited to specifically listed vehicles.

Workers Compensation and Employers Liability

The cert row shows the policy number, period, and three limits: Each Accident, Disease Policy Limit, and Disease Each Employee. Standard is $1,000,000 on each.

In Texas, workers compensation is optional for most private employers — the state operates a non-subscriber system where employers can legally decline to participate. A blank WC row on a certificate for a Texas contractor does not automatically mean non-compliance, but it warrants a direct question about non-subscriber status.

Section 4: Description of Operations — The Most Important Field

This free-text field is the third — and most important — place where mistakes hide. It is where additional insured designations, endorsement confirmations, primary and noncontributory language, waiver of subrogation language, and project-specific requirements are written in.

A typical Description of Operations box for a construction subcontractor might read: ABC General Contractor LLC is named as additional insured on the general liability policy per ISO form CG 20 10 11 85 for ongoing operations and CG 20 37 10 01 for completed operations. Coverage is primary and noncontributory per ISO form CG 20 01 04 13. Waiver of subrogation applies to general liability, commercial auto, and workers compensation policies.

Each piece of that language matters:

• Additional insured designation: The named party needs to be added as an additional insured on the underlying policy, not just mentioned on the certificate. ISO form CG 20 10 covers ongoing operations; CG 20 37 covers completed operations. Many contracts require both. If the cert mentions CG 20 10 but not CG 20 37, the GC has no coverage for claims that arise after the project is done.
• Primary and noncontributory: Without this language, if a claim involves both the sub's policy and the GC's policy, the sub's carrier can argue that the GC's policy should contribute proportionally. Primary and noncontributory language — provided via ISO endorsement CG 20 01 or equivalent — requires the sub's policy to pay first without contribution from the GC's policy. See our full guide on primary and noncontributory coverage.
• Waiver of subrogation: The sub's carrier agrees not to pursue the GC for recovery after paying a claim.

What the Description of Operations cannot do: it cannot grant coverage that does not exist in the underlying policy. If the policy does not have a CG 20 10 endorsement attached, writing "additional insured per CG 20 10" in the description box does nothing. The certificate is a summary document — the policy controls. This distinction matters at claim time, which is when most people discover the difference.

Section 5: Certificate Holder (Bottom Right)

The certificate holder is the party who receives the certificate. Being listed as a certificate holder does not grant any insurance rights. It means only that the holder is on record to receive cancellation notices.

This is the fourth field where mistakes hide. Many people believe that being listed as the certificate holder makes them an additional insured. It does not. Additional insured status requires a specific endorsement on the underlying policy. A certificate holder has notification rights only.

If you are a GC, landlord, or project owner who requires insurance coverage from vendors and subs, you need to be listed as an additional insured in the Description of Operations box — not merely as the certificate holder. These are two different fields with two different legal effects. See our guide on Additional Insured vs. Certificate Holder for the complete breakdown.

The Cancellation Clause and the Disclaimer

The cancellation clause

The current ACORD 25 language states that notice will be delivered in accordance with the policy provisions — replacing the older language that promised 30 days written notice. If your contract requires 30-day cancellation notice, verify the policy has a 30-day notice endorsement. The certificate language alone does not create that obligation.

The disclaimer

At the top of every ACORD 25: THIS CERTIFICATE IS ISSUED AS A MATTER OF INFORMATION ONLY AND CONFERS NO RIGHTS UPON THE CERTIFICATE HOLDER. THIS CERTIFICATE DOES NOT AFFIRMATIVELY OR NEGATIVELY AMEND, EXTEND OR ALTER THE COVERAGE AFFORDED BY THE POLICIES BELOW.

Courts have consistently held that certificates of insurance do not create or modify coverage. If the certificate says one thing and the underlying policy says another, the policy controls. A certificate can promise additional insured status that does not exist in the policy, and the promise is meaningless at claim time. The certificate is evidence of insurance, not a guarantee of insurance.

The Fifth Place Mistakes Hide: Policy Numbers

Policy numbers link the certificate to a specific policy. Certificate fraud occurs — particularly in construction, where insurance certificates are required to start work. Contractors who cannot qualify for insurance occasionally submit false certificates. The way to catch this: call the producer listed on the certificate, give them the insured name and policy number, and ask them to confirm the certificate reflects active coverage. A carrier that has the policy in force will confirm it immediately.

Reading Certificates as a GC or Property Manager

Quick checklist for each certificate that crosses your desk:

1. Named insured: Does it match the legal entity on the contract?
2. Policy dates: Are all policies currently in force and covering the project period?
3. GL limits: Do they meet your contract minimum (typically $1M/$2M)?
4. Occurrence vs. claims-made: Is GL written on an occurrence basis?
5. Auto coverage: Does it include hired and non-owned auto, not just scheduled autos?
6. Workers comp: Is it present, or is there documented non-subscriber status?
7. Description of Operations: Does it name you as additional insured with the correct ISO form numbers — CG 20 10 for ongoing, CG 20 37 for completed? Does it include primary and noncontributory language? Is there a waiver of subrogation?
8. Certificate holder: Is your organization listed with the correct legal name and address?

If any of these are missing or wrong, send it back with specific corrections noted. Most problems can be fixed with a reissued certificate in under an hour.

Frequently Asked Questions

Can a certificate change what a policy covers?

No. The ACORD 25 disclaimer is explicit: the certificate does not amend, extend, or alter coverage. The policy governs. If a description on the certificate is inconsistent with the policy, the policy controls at claim time.

What is the difference between the certificate holder and an additional insured?

The certificate holder receives notification rights only — they are on the distribution list for cancellation notices. An additional insured has actual coverage rights under the policy, meaning they can file claims against the policy for covered incidents. You need to be named as an additional insured in the Description of Operations box, not just listed as the certificate holder.

What is the CG 20 10 and CG 20 37 distinction?

ISO form CG 20 10 adds an additional insured for ongoing operations — work currently in progress. ISO form CG 20 37 adds an additional insured for completed operations — work already done. Most construction contracts require both. If a Description of Operations mentions CG 20 10 but not CG 20 37, the additional insured has no coverage for post-completion claims.

How quickly should I be able to get a certificate?

A competent broker issues routine certificates within minutes. If a broker regularly takes days to produce a standard certificate, that is an operational problem that directly costs contractors money and credibility on active jobs.
