ACORD 25: The Definitive Field-by-Field Guide

The ACORD 25 is the most widely used insurance certificate form in the United States. If you work in commercial real estate, construction, procurement, or risk management, you encounter this form daily. Yet most professionals never receive formal training on how to read it. They learn through experience — and sometimes through costly mistakes.

This guide walks through every section of the ACORD 25 form, field by field, so you understand exactly what you are looking at and what to verify.

What Is the ACORD 25 Form?

The ACORD 25, formally titled "Certificate of Liability Insurance," is a standardized form created and maintained by the Association for Cooperative Operations Research and Development (ACORD). ACORD is a nonprofit organization that develops data standards for the global insurance industry. Their forms are used by virtually every insurance agent, broker, and carrier in the United States.

The ACORD 25 serves a single purpose: to provide evidence that an insured party has specific liability insurance coverages in effect. It is issued by an insurance producer (agent or broker) on behalf of the insured, and delivered to a certificate holder — typically a party that has a contractual relationship with the insured and needs proof of coverage.

What the ACORD 25 Proves

The form proves that, as of the date of issue, the named insured has liability insurance policies in effect with the coverages and limits shown on the certificate. It summarizes information from the underlying policies without modifying those policies in any way.

What the ACORD 25 Does NOT Prove

The certificate does not guarantee future coverage. A policy can be cancelled the day after the certificate is issued. The certificate does not grant any rights to the certificate holder. It does not amend, extend, or alter the terms of the underlying policies. And it is not a contract between the certificate holder and the insurer.

Who Issues the ACORD 25

Only the insurance producer — the agent or broker of record — can issue an ACORD 25. The insured (the business that holds the policies) does not issue their own certificates. They request certificates from their agent, who generates them using agency management software. This is an important distinction because it means the producer is attesting to the accuracy of the information on the form.

Section-by-Section Breakdown

The ACORD 25 form is organized into clearly defined sections, each containing specific data points. Understanding the layout allows you to quickly locate the information you need during compliance verification.

Header: Date and Certificate Number

At the very top of the form, you will find two fields:

• DATE (MM/DD/YYYY): The date the certificate was issued. This is the effective date of the information on the form. Any policy changes that occur after this date are not reflected.
• Certificate Number: An optional tracking number assigned by the producer. Not all agencies use this field, and when populated, it serves primarily as an internal reference.

The issue date is critical. If a certificate is more than a few days old, you should question whether the information is still current. Best practice is to require certificates dated within 30 days of receipt.

Producer Section

The Producer section occupies the upper-left portion of the form and identifies the insurance agent or broker who issued the certificate.

Fields include:

• Producer name and address: The agency's legal name and mailing address
• Contact name: A specific person at the agency who can answer questions
• Phone and fax numbers: Direct contact information
• Email address: The producer contact's email

This section matters for verification. If you suspect a certificate is fraudulent, or if you need to confirm that the information is accurate, you contact the producer directly. Fraudulent COIs are a real problem in the industry — some estimates suggest that 5-10% of certificates in circulation contain inaccurate information. The producer section gives you a path to verify.

Insured Section

The Insured section appears directly below the Producer section and identifies the policyholder — the business or individual that holds the insurance policies listed on the certificate.

Fields include:

• Insured name: The legal entity name of the policyholder
• Mailing address: The insured's business address

This section requires careful attention during verification. The insured name must match the legal entity you have a contract with. Common issues include:

• DBA mismatches: The certificate shows a DBA (doing business as) name, but your contract is with the legal entity
• Parent vs. subsidiary: The certificate names the parent company, but you hired a subsidiary
• Spelling variations: Minor differences that could indicate a different entity entirely
• Stale addresses: The address does not match what you have on file

If the insured name does not match your vendor's legal name exactly, request clarification before accepting the certificate.

Insurers Affording Coverage (A through F)

The center-left section of the ACORD 25 lists the insurance companies that underwrite the policies shown on the certificate. The form accommodates up to six insurers, labeled Insurer A through Insurer F.

For each insurer, two fields are provided:

• Insurer name: The full legal name of the insurance company
• NAIC number: The five-digit identifier assigned by the National Association of Insurance Commissioners

The NAIC number is particularly important. It allows you to look up the insurer in the NAIC database to verify:

• That the company actually exists and is licensed to write insurance
• The company's financial strength rating (AM Best, S&P, etc.)
• Whether the company is authorized to do business in the relevant state

An insurer with a low financial strength rating or one that is not admitted in your state presents a risk. If the insurer becomes insolvent, claims may go unpaid. Most compliance programs require insurers to maintain at minimum an AM Best rating of A- (Excellent) and a Financial Size Category of VII or higher.

Coverage Grid: The Heart of the Form

The center of the ACORD 25 form contains a grid that summarizes the insured's liability coverages. Each row represents a different type of insurance. For each row, the form shows the insurer letter (corresponding to the Insurers A-F section), policy number, effective date, expiration date, and applicable limits.

General Liability Row

The Commercial General Liability (CGL) row is typically the first and most scrutinized section of the coverage grid.

Type indicators (checkboxes):

• Commercial General Liability: Confirms this is a CGL policy
• Claims-Made vs. Occurrence: The coverage trigger. This is a critical distinction:
  • Occurrence policies cover claims arising from incidents that occur during the policy period, regardless of when the claim is filed
  • Claims-Made policies cover claims that are both made and reported during the policy period. If you discover damage after the policy expires, there may be no coverage unless the insured purchased an extended reporting period (tail coverage)

For most compliance programs, occurrence-based CGL coverage is preferred because it provides broader long-tail protection.

Limits shown:

• Each Occurrence: The maximum the insurer will pay for a single occurrence. The standard minimum requirement is $1,000,000.
• Damage to Rented Premises (Each Occurrence): Coverage for property damage to premises rented to the insured. Commonly $100,000 to $300,000. This is relevant if the insured is a tenant.
• Med Exp (Any One Person): Medical expense coverage for third parties injured on the insured's premises, regardless of fault. Typically $5,000 to $10,000. This is a minor coverage that rarely drives compliance decisions.
• Personal & Advertising Injury: Coverage for non-physical harms including defamation, slander, libel, false arrest, wrongful eviction, and copyright infringement in advertising. Usually equal to the each occurrence limit ($1,000,000).
• General Aggregate: The total maximum the insurer will pay for all covered claims during the policy period, excluding products-completed operations claims. Standard is $2,000,000 (twice the each occurrence limit).
• Products-Completed Operations Aggregate: The total maximum for claims arising from the insured's products or from completed operations. Standard is $2,000,000. This is particularly important in construction, where claims often surface after the work is done.

Additional checkboxes in the General Liability section:

• Policy / Project / Location: Indicates whether the General Aggregate applies per policy, per project, or per location. A per-project aggregate is preferable for construction because it means claims on one project do not erode the aggregate available for another project.
• Other: Used for non-standard aggregate applications

Automobile Liability Row

The Automobile Liability row covers the insured's vehicle-related exposures.

Type indicators (checkboxes):

• Any Auto: The broadest designation — covers all vehicles regardless of ownership
• All Owned Autos Only: Covers only vehicles titled to the insured
• Hired Autos Only: Covers vehicles rented or borrowed by the insured
• Scheduled Autos: Covers only specific vehicles listed on the policy by VIN
• Non-Owned Autos Only: Covers vehicles owned by employees or others when used for the insured's business

For most compliance purposes, Any Auto or a combination of All Owned, Hired, and Non-Owned provides adequate coverage.

Limits shown:

• Combined Single Limit (Each Accident): A single limit that applies to both bodily injury and property damage per accident. The standard minimum is $1,000,000.
• Bodily Injury (Per Person): If not using CSL, the maximum for bodily injury to one person
• Bodily Injury (Per Accident): The maximum for all bodily injuries in a single accident
• Property Damage (Per Accident): The maximum for property damage in a single accident

Most modern policies and compliance programs use the Combined Single Limit approach because it provides more flexible coverage than split limits.

Umbrella/Excess Liability Row

The Umbrella Liability (or Excess Liability) row provides coverage above the limits of the underlying policies (CGL, Auto, Employers' Liability).

Type indicators:

• Umbrella Liability: A broader form that can provide coverage for claims not covered by underlying policies (drop-down coverage) in addition to excess limits
• Excess Liability: Strictly follows the terms of the underlying policies and only provides additional limits
• Occurrence vs. Claims-Made: Same distinction as General Liability

Limits shown:

• Each Occurrence: The maximum the umbrella/excess policy will pay per occurrence, above the underlying limits
• Aggregate: The total maximum for all claims during the policy period
• DED (Deductible) or Retention: The self-insured retention (SIR) that the insured must pay before the umbrella/excess policy responds. A retention applies to claims that fall within the umbrella's drop-down coverage but are not covered by an underlying policy.

Umbrella limits are particularly important for high-value contracts. A vendor with $1M in General Liability and a $5M Umbrella effectively has $6M in coverage for a single occurrence. Many property owners and general contractors require $5M to $10M in Umbrella coverage depending on the scope of work.

Workers Compensation and Employers' Liability Row

The Workers' Compensation row covers the insured's obligations to employees who are injured on the job.

Workers' Compensation limits:

• Per Statute: Workers' Compensation benefits are defined by state statute, not by policy limits. The "per statute" checkbox indicates that the policy provides whatever benefits the applicable state law requires. This should always be checked.
• Statutory Limits Apply: Additional confirmation that statutory limits are in effect

Employers' Liability limits (the B-side of a Workers' Comp policy):

• E.L. Each Accident: The maximum payout for a single workplace accident. Standard minimum is $500,000 or $1,000,000.
• E.L. Disease — Each Employee: The maximum for an occupational disease claim by a single employee. Standard minimum is $500,000 or $1,000,000.
• E.L. Disease — Policy Limit: The aggregate maximum for all disease claims during the policy period. Standard minimum is $500,000 or $1,000,000.

Workers' Compensation coverage is required by law in 49 states (Texas being the notable exception, where it is optional for most private employers). If a vendor has employees performing work on your property and does not carry Workers' Comp, you may be liable for their employees' injuries under most states' statutory employer doctrines.

Additional fields:

• Any Proprietor/Partner/Executive Officer/Member Excluded?: If checked "Yes," it means certain individuals are excluded from Workers' Comp coverage. This is common for sole proprietors and partners in some states but should be flagged if the excluded individuals will be performing work on your property.

Description of Operations / Locations / Vehicles

The Description of Operations section is a free-text field at the bottom-center of the form. Despite being free-text, this section carries enormous compliance significance because it contains:

Project and contract references: The description should identify the specific project, property, or contract the certificate pertains to. For example: "RE: 100 Main Street renovation project, Contract #2025-0847."

Additional Insured language: This is where the producer indicates that the certificate holder has been added as an Additional Insured on the insured's policy. Common language includes:

• "Certificate holder is named as Additional Insured per CG 20 10 and CG 20 37"
• "Additional Insured as required by written contract"
• "Blanket Additional Insured per policy endorsement"

Waiver of Subrogation: Language indicating that the insured's carrier waives its right to subrogate (seek reimbursement) against the certificate holder. For example: "Waiver of Subrogation applies in favor of the certificate holder per policy endorsement."

Primary and Non-Contributory: Language indicating that the insured's policy is primary (pays first) and non-contributory (the certificate holder's own insurance does not have to contribute). For example: "Coverage is primary and non-contributory as required by written contract."

Certificate Holder Section

The Certificate Holder section appears in the lower-left of the form and identifies the party that requested the certificate.

Fields include:

• Name: The legal name of the entity requesting the certificate
• Address: The mailing address for the certificate holder

The certificate holder name must exactly match the entity that has a contractual relationship with the insured. Common errors include:

• Property management company listed instead of the property owner
• Abbreviated names or informal names instead of the full legal entity
• Wrong address or suite number
• Missing "LLC," "Inc.," or other entity designation

These may seem like minor administrative details, but in a claims scenario, a mismatched certificate holder name can create ambiguity about whether the endorsements apply to your entity.

Cancellation Clause

The Cancellation section appears in the lower-right of the form and contains standard language about policy cancellation notification.

The current ACORD 25 form (revised 2016) includes this language:

"Should any of the above described policies be cancelled before the expiration date thereof, notice will be delivered in accordance with the policy provisions."

This means the certificate holder receives cancellation notice only if the underlying policy includes an endorsement requiring such notice. The form itself does not create a notification obligation. In earlier versions of the ACORD 25 (pre-2009), this section included a specific number of days' notice. The current version defers entirely to the policy provisions.

If your contract requires 30 days' advance notice of cancellation, you must verify that an endorsement providing that notice period is attached to the underlying policy. Do not rely on the certificate language alone.

Authorized Representative Signature

The form concludes with a signature line for the producer's authorized representative. This signature attests that the information on the certificate is accurate as of the issue date. An unsigned certificate should not be accepted — the signature is the producer's attestation of accuracy.

Common Mistakes When Reading an ACORD 25

Even experienced professionals make errors when reviewing certificates. Here are the most frequent mistakes:

Mistake 1: Checking Only the Limits

Many reviewers jump straight to the dollar amounts and ignore everything else. They confirm the per-occurrence limit meets the requirement and move on. But a certificate can have the right limits and still be non-compliant if the dates are wrong, the insured name does not match, the coverage trigger is claims-made instead of occurrence, or the required endorsements are missing.

Mistake 2: Ignoring the NAIC Numbers

The NAIC number allows you to verify that the insurer is legitimate, financially stable, and authorized to write insurance in the relevant state. Skipping this check leaves you vulnerable to certificates listing fictitious or financially impaired carriers.

Mistake 3: Assuming "Certificate Holder" Means "Additional Insured"

This is the most expensive mistake in COI compliance. Being named as the certificate holder gives you the right to receive the certificate document and potentially cancellation notices. It does not give you coverage under the insured's policy. Additional Insured status must be separately verified in the Description of Operations or through actual endorsement copies.

Mistake 4: Not Reading the Description of Operations

The Description of Operations section is where project-specific language lives. If you require Waiver of Subrogation, Primary and Non-Contributory status, or Additional Insured coverage, the language should appear here. A blank or generic Description of Operations ("For informational purposes only") is a red flag.

Mistake 5: Accepting Certificates with Past Expiration Dates

Policies on the certificate grid have expiration dates. If any policy has expired, the certificate is not evidence of current coverage for that policy type. Always check every expiration date, not just the first one — it is common for General Liability and Auto to expire on one date while Workers' Comp expires on a different date.

Mistake 6: Not Verifying the Aggregate Basis

For General Liability, the aggregate can apply per policy, per project, or per location. If you have a construction project and the aggregate applies per policy, claims from the insured's other projects can erode the aggregate available for your project. Per-project aggregates provide better protection.

Mistake 7: Overlooking the Claims-Made vs. Occurrence Distinction

A claims-made General Liability policy provides no coverage for claims reported after the policy expires, unless the insured purchases extended reporting (tail) coverage. If your vendor switches carriers or goes out of business, claims-made coverage can leave you unprotected for incidents that occurred during the policy period but are reported later.

How AI Reads ACORD 25 Forms vs. Manual Review

The traditional approach to ACORD 25 review involves a human reviewer opening a PDF, visually scanning each section, and manually comparing values against a requirements checklist. This process typically takes 10 to 20 minutes per certificate and is subject to human error, fatigue, and inconsistency.

AI-powered certificate review fundamentally changes this process:

Structured Data Extraction

AI vision models process the ACORD 25 as an image and extract every field into structured data. This means every limit value, every date, every checkbox, every line of the Description of Operations becomes a discrete data point that can be queried, compared, and stored. There is no manual data entry step.

Rule-Based Compliance Checking

Once data is extracted, the AI applies your specific compliance rules programmatically. If you require $1,000,000 in General Liability per occurrence, the system compares the extracted value against that threshold and returns a pass or fail result. Every rule is applied every time, eliminating the inconsistency of human review.

Pattern Recognition in Description of Operations

The Description of Operations is a free-text field, which makes it challenging for traditional OCR systems. Modern AI models understand natural language, meaning they can identify Additional Insured language, Waiver of Subrogation provisions, and Primary and Non-Contributory language regardless of how the producer worded it.

Speed and Scale

AI processes an ACORD 25 in seconds, not minutes. This means a portfolio of 5,000 certificates that would take a team of reviewers weeks to process can be verified in hours. And every certificate receives the same thorough review — there is no "Friday afternoon effect" where reviewers rush through the last batch before the weekend.

Audit Trail

Every AI decision is logged and auditable. For each certificate, the system records exactly what was extracted, what rules were applied, and what the compliance determination was. This creates a defensible audit trail that manual review simply cannot match.

Limitations

AI is not infallible. Poorly scanned documents, handwritten modifications, and unusual form layouts can reduce extraction accuracy. Multi-page endorsements that are separate from the ACORD 25 itself require additional processing. And AI cannot make judgment calls about borderline compliance situations the way an experienced reviewer can.

The optimal approach combines AI extraction and rule-based verification with human oversight for exceptions and edge cases. AI handles the volume; humans handle the nuance.
