How to Read an ACORD 25 Certificate of Insurance: Field-by-Field Guide

Learn how to read an ACORD 25 certificate of insurance with this field-by-field guide covering every section from producer to cancellation.

ACORD 25COI guideinsurance compliancecertificate of insurance

To read an ACORD 25 certificate of insurance, start at the top with the producer and insured information, then review the coverages table for policy types, limits, and dates. Check the Description of Operations section for endorsement language and project-specific details, and verify that the certificate holder section lists your organization's exact legal name. Each section serves a distinct purpose, and knowing what to look for in each one is the difference between a meaningful compliance review and a rubber stamp.

The ACORD 25 — formally titled "Certificate of Liability Insurance" — is the most widely used certificate form in the United States. Published by the Association for Cooperative Operations Research and Development, it provides a standardized format for summarizing a business's liability insurance coverages on a single page. Despite its compact layout, the form contains a density of information that can be difficult to parse without guidance, especially for operations professionals who are not insurance specialists.

This guide walks through every section of the ACORD 25 form, explains what each field means, and highlights what operations teams should look for when verifying vendor compliance.

The Header: Date, Producer, and Insured

The top portion of the ACORD 25 contains three critical pieces of information.

Certificate Date — Located in the upper-right corner, this is the date the certificate was issued. It is not the policy effective date. The certificate date tells you when the document was generated, which helps determine how current the information is. A certificate dated six months ago may still be technically valid if the policies have not expired, but it also means any changes made since issuance are not reflected.

Producer — The left column at the top identifies the insurance producer (agent or broker) who issued the certificate. This section includes:

  • Producer name (the agency or brokerage)
  • Contact name and phone/fax/email
  • Full mailing address

The producer is the first person to contact when you need a corrected certificate, an endorsement copy, or a renewal. Keep this information accessible — you will use it more often than you expect.

Insured — The right column at the top identifies the named insured. This is the entity whose insurance coverages are being certified. The section includes the insured's legal name and mailing address.

What to verify: The insured name must exactly match the legal entity you contracted with. If your contract is with "Apex Mechanical Services LLC" and the certificate lists "Apex Mechanical Services Inc.," that is a discrepancy worth flagging. Coverage may not extend to the entity you actually hired.

Insurers Affording Coverage

Below the producer and insured sections, the ACORD 25 lists the insurance companies that provide the coverage shown on the certificate. The form accommodates up to five insurers, labeled Insurer A through Insurer E. For each insurer, two pieces of information appear:

  1. Insurer name — The full name of the insurance company
  2. NAIC number — The National Association of Insurance Commissioners identifier, a five-digit code unique to each insurer

What to verify: The NAIC number allows you to look up the insurer's financial strength rating through A.M. Best, S&P, or Moody's. Most contracts require insurers to hold a minimum rating (typically A- VII from A.M. Best). An insurer with a poor rating or no rating at all may not have the financial capacity to pay claims when they arise. The NAIC number also helps distinguish between similarly named insurers and confirms you are looking at the correct entity.

The Coverages Table: The Heart of the Certificate

The coverages table occupies the center of the ACORD 25 and contains the most critical compliance data. Each row represents a different type of insurance coverage. The standard coverage types on the ACORD 25 are:

Commercial General Liability (CGL)

This row shows the insured's general liability coverage. Key fields include:

  • Policy Number — The unique identifier for this CGL policy
  • Policy Effective Date / Expiration Date — The period during which the policy is active (format: MM/DD/YYYY)
  • Occurrence vs. Claims-Made — A checkbox indicating the policy form. Occurrence-form policies cover incidents that occur during the policy period regardless of when the claim is filed. Claims-made policies cover claims reported during the policy period. Most contracts require occurrence form.
  • Each Occurrence Limit — The maximum the insurer will pay for a single occurrence (bodily injury or property damage)
  • General Aggregate Limit — The maximum the insurer will pay for all CGL claims during the policy period (excluding products/completed operations)
  • Products/Completed Operations Aggregate — The maximum for claims arising from the insured's products or completed work
  • Personal & Advertising Injury — The limit for claims such as libel, slander, or copyright infringement
  • Damage to Rented Premises — The limit for fire damage to premises rented by the insured
  • Medical Expense — The per-person limit for medical payments regardless of fault

What to verify: Compare each limit against your contractual requirements. Pay special attention to the occurrence versus claims-made checkbox — claims-made CGL is acceptable in some contexts (professional liability) but is generally not acceptable for contractor general liability. Confirm the aggregate has not been eroded by checking if the "policy" or "project" box is checked next to the aggregate (per-project aggregate is preferred for construction).

Automobile Liability

This row covers the insured's commercial auto insurance. Key fields include:

  • Policy Number and Dates — Same format as CGL
  • Any Auto / Owned / Hired / Non-Owned — Checkboxes indicating which vehicles are covered. "Any Auto" is the broadest and most commonly required
  • Combined Single Limit (CSL) — The single limit per accident for both bodily injury and property damage combined
  • Bodily Injury Per Person / Per Accident — If split limits are used instead of CSL
  • Property Damage — If split limits are used

What to verify: "Any Auto" should be checked for most vendor requirements because it covers owned vehicles, hired vehicles, and non-owned vehicles (employees' personal cars used for business). If only "Owned Autos" is checked and the vendor's employee causes an accident in their personal vehicle while on the job, there may be no auto coverage. The combined single limit should meet your contractual minimum.

Umbrella / Excess Liability

This row shows excess coverage that sits above the underlying CGL, auto, and employers liability limits. Key fields include:

  • Policy Number and Dates
  • Each Occurrence — The umbrella per-occurrence limit
  • Aggregate — The umbrella aggregate limit
  • Retention/Deductible — The amount the insured must pay before the umbrella responds (similar to a deductible)

What to verify: Confirm the umbrella limits meet your requirements. For construction projects, umbrella limits of $5M to $25M are common depending on project size. Verify that the umbrella policy follows form over the underlying CGL, auto, and employers liability policies. If the umbrella does not follow form over a specific underlying policy, there may be a gap in excess coverage for that coverage type.

Workers Compensation and Employers Liability

This row covers the insured's obligations for workplace injuries. Key fields include:

  • WC Statutory Limits — A checkbox confirming coverage meets the statutory requirements of the applicable state(s)
  • Employers Liability — Each Accident — The per-accident limit for employers liability claims
  • Employers Liability — Disease (Each Employee) — The per-employee disease limit
  • Employers Liability — Disease (Policy Limit) — The aggregate disease limit

What to verify: The statutory limits checkbox should always be marked. Check that the employers liability limits meet your contract requirements (commonly $1M each accident, $1M disease each employee, $1M disease policy limit). If the insured operates in multiple states, confirm that the applicable states are listed. Some sole proprietors or corporate officers are exempt from Workers Compensation in certain states — if a vendor claims exemption, request a copy of the state-issued exemption certificate.

Description of Operations / Locations / Vehicles

This free-text section below the coverages table is one of the most important — and most overlooked — areas of the certificate. The producer uses this space to add project-specific details and endorsement references. Common entries include:

  • Project or contract reference — "Re: ABC Office Building, 123 Main Street, Atlanta, GA"
  • Additional Insured language — "Certificate Holder is included as Additional Insured per CG 20 10 04 13 and CG 20 37 04 13"
  • Waiver of Subrogation — "Waiver of Subrogation applies per CG 24 04 in favor of Certificate Holder"
  • Primary and Non-Contributory — "Coverage is Primary and Non-Contributory as required by written contract"
  • Thirty-day cancellation notice — "30 days notice of cancellation will be provided to Certificate Holder" (note: this language has limited enforceability)

What to verify: This section is where you confirm whether critical endorsement requirements are met. Look for the following items, and note their presence or absence:

  1. Additional Insured — Is your entity specifically referenced? Are endorsement form numbers (CG 20 10, CG 20 37) cited?
  2. Waiver of Subrogation — Is WOS referenced? Is the endorsement form (CG 24 04) cited?
  3. Primary and Non-Contributory — Is P&NC language present?
  4. Project specificity — Does the description reference your specific project or contract?

A critical caveat: the ACORD 25 form includes standard language stating that the certificate "is issued as a matter of information only and confers no rights upon the certificate holder." This means the endorsement language in the Description of Operations is informational, not contractual. The actual endorsement document attached to the policy is what creates the coverage. Always request copies of referenced endorsements for your compliance files.

Certificate Holder

The lower-left section of the ACORD 25 identifies the certificate holder — the entity that requested the certificate. This section includes the certificate holder's name and mailing address.

What to verify: Your exact legal entity name must appear here. This is more than a formality. In many cases, the certificate holder name is used to populate the Additional Insured endorsement schedule. If the name in the certificate holder box is wrong, the endorsement may also be wrong — which could void your additional insured protection when you need it most.

Common errors include:

  • Abbreviated names ("Smith Dev" instead of "Smith Development Group LLC")
  • Missing entity designators ("Smith Development" instead of "Smith Development Group LLC")
  • Parent company listed instead of the subsidiary that holds the contract
  • Outdated names from before a merger or name change

If the certificate holder name is incorrect, request a corrected certificate before accepting it as compliant.

Cancellation

The lower-right section of the ACORD 25 contains cancellation language. In older versions of the form (pre-2009), this section stated that the insurer would "endeavor to" mail notice to the certificate holder if the policy was canceled before its expiration date. The current version has removed the "endeavor to" language and instead includes a statement that the cancellation provisions of the policy apply.

What to verify: Understand that the cancellation section of the ACORD 25 does not create an obligation for the insurer to notify you of cancellation. Even if "30 days notice" appears in the Description of Operations, enforcement of that commitment varies by state and by insurer. The only reliable way to ensure continuous coverage is proactive expiration monitoring and regular certificate renewal requests.

Authorized Representative Signature

At the bottom of the form, the authorized representative of the producer signs the certificate. This signature affirms that the information on the certificate is accurate as of the date of issuance.

What to verify: Ensure the signature is present. An unsigned certificate has not been formally issued and should not be accepted as proof of coverage. Some certificates are generated electronically with a digital signature or stamped signature — these are generally acceptable in modern practice.

Putting It All Together: A Compliance Review Workflow

When a COI arrives on your desk (or in your inbox), follow this systematic review:

  1. Verify the insured name matches your contracted entity
  2. Check all coverage types are present per your contract requirements
  3. Compare every limit against your requirement minimums
  4. Verify all policies are active — no expiration dates in the past
  5. Flag policies expiring within 30 days for renewal tracking
  6. Read the Description of Operations for endorsement references
  7. Confirm certificate holder name matches your exact legal entity
  8. Note the insurer NAIC codes and verify financial strength ratings
  9. Request actual endorsement documents for any referenced endorsements
  10. Log the review in your compliance tracking system with timestamps

This process takes 10-15 minutes per certificate when done manually. For organizations managing large vendor portfolios, that time adds up quickly. Automated tools like unifi.ai extract every field from the ACORD 25, compare them against your requirement templates, and produce a compliance report in seconds — with every check documented for your audit trail.

Common Misreadings and Pitfalls

Misreading 1: Confusing the certificate date with the policy effective date. The certificate date is when the document was generated. The policy effective date is when coverage begins. These are different dates with different implications.

Misreading 2: Assuming "Additional Insured" in the description means you have coverage. The Description of Operations is informational. Only the actual endorsement document creates coverage. A reference on the COI without a corresponding endorsement on the policy is meaningless in a claim.

Misreading 3: Ignoring the aggregate limit. You check the per-occurrence limit and it meets your requirement. But the aggregate — the total the insurer will pay for all claims during the period — may be inadequate, especially if the vendor has multiple projects and the aggregate is shared across all of them.

Misreading 4: Not distinguishing between policy limits and umbrella limits. A vendor may appear to have adequate coverage because their umbrella brings the total to the required amount. But if your contract requires the primary CGL to meet a specific threshold, the umbrella does not substitute for inadequate primary limits.

Misreading 5: Accepting a certificate as a static guarantee. A COI is a snapshot. The policy can be canceled, modified, or non-renewed the day after the certificate is issued, and the certificate you hold will not update itself. Continuous compliance requires continuous monitoring.

Frequently Asked Questions

What is the difference between the ACORD 25 and the ACORD 28?

The ACORD 25 is the Certificate of Liability Insurance, covering general liability, auto, umbrella, and workers compensation. The ACORD 28 is the Evidence of Commercial Property Insurance, covering building and contents coverage. They serve different purposes — the ACORD 25 proves liability coverage (protection against third-party claims), while the ACORD 28 proves property coverage (protection against physical damage to the insured's property). Some contracts require both.

Can a certificate of insurance be revoked or recalled?

Technically, no. Once issued, the certificate is a statement of fact as of the issue date. However, if the underlying policy is canceled or the certificate was issued in error, the insurer or producer may issue a corrected certificate or a cancellation notice. The certificate holder has no legal right to prevent a policy from being canceled — the contract between the insured and the insurer governs cancellation terms.

Why do some COIs have multiple insurers listed?

A business may place different coverage types with different insurance companies. For example, Insurer A might provide the CGL, Insurer B the automobile coverage, and Insurer C the workers compensation. Each insurer is listed separately with its NAIC code, and each coverage row in the table indicates which insurer provides that coverage by letter designation (A, B, C, etc.).

What does "SIR" mean on a certificate?

SIR stands for Self-Insured Retention. It functions similarly to a deductible — the insured must pay the SIR amount before the insurance policy begins to pay. SIRs are common on umbrella and excess policies. A high SIR (e.g., $25,000 or more) means the insured bears significant out-of-pocket costs before insurance responds. If you see an SIR on a certificate, verify that the insured has the financial capacity to fund it.

Is a digitally issued or emailed COI as valid as a printed one?

Yes. The ACORD 25 does not require physical signatures or hard-copy delivery to be valid. Electronically generated certificates with digital or facsimile signatures are standard practice and are accepted throughout the insurance industry. What matters is the accuracy of the information, not the delivery method.


Reading an ACORD 25 accurately is the foundation of any COI compliance program. Every field matters, and the details that are easiest to overlook are often the ones that matter most when a claim arrives.
