What Are ACORD Forms in Insurance

ACORD forms are standardized documents used throughout the insurance industry for applications, certificates of insurance, evidence of coverage, and binders. ACORD - the Association for Cooperative Operations Research and Development - is a non-profit standards organization founded in 1970 that develops and maintains the form library used by virtually every US insurance carrier, agency management system, and commercial policyholder.

The value of acord-form standardization is interoperability: a carrier in Hartford can receive a commercial lines application from an agency in Texas and read every field without custom interpretation. A certificate holder in Chicago can receive an ACORD 25 from an agency in Miami and know exactly which fields confirm coverage dates, limits, and additional insured status. Without standardization, each agency-carrier data exchange would require proprietary forms and custom workflows.

Key Takeaways

• ACORD was founded in 1970 and maintains over 600 standardized form templates used across all US carriers and most global markets.
• ACORD 25 is the Certificate of Liability Insurance - the most commonly issued form in commercial insurance transactions.
• ACORD 27 covers personal/residential property evidence of insurance; ACORD 28 covers commercial property evidence of insurance.
• The ACORD 125 (commercial lines application) and its supplements - ACORD 126 (CGL), ACORD 130 (workers compensation), ACORD 140 (commercial property) - form the core commercial application package.
• ACORD's Digital Transformation program is replacing static PDF forms with API-based data exchange through ACORD XML standards and IVANS integration.
• ACORD forms do not modify policies. They are documentation tools. A certificate that shows coverage does not create or extend coverage - the underlying policy controls.

What ACORD Is and Why It Exists

ACORD (Association for Cooperative Operations Research and Development) was formed in 1970 by a group of insurance carriers and agencies that recognized the industry's fragmentation problem. Before ACORD, each carrier used proprietary forms. An agency placing business with 12 carriers maintained 12 different sets of application forms, each with different field structures and terminology.

ACORD developed a common form library that all participating carriers would accept. Adoption spread rapidly. Today, ACORD standards are used by more than 36,000 insurance organizations across 20+ countries. In the US, virtually all commercial and personal lines applications, certificates, and evidence forms follow ACORD formatting.

ACORD forms are not legally binding in themselves - they are documentation tools. The insurance policy governs coverage. An ACORD certificate that shows $1 million in general liability limits does not create those limits; it reflects what the underlying policy provides. When there is a conflict between the certificate and the policy, the policy controls.

The Most Commonly Used ACORD Forms

ACORD 25 - Certificate of Liability Insurance

ACORD 25 is the most widely issued form in commercial insurance. It documents liability coverage for a named insured and is used whenever a party - a landlord, project owner, lender, or government entity - requires proof that a contractor, vendor, or tenant carries liability coverage.

The current edition is ACORD 25 (2016/01). ACORD 25 shows: the producer/agency, the insurer(s), the named insured, policy types and numbers, coverage effective dates, limits by coverage line (GL, auto, umbrella, workers comp, professional), additional insured status, waiver of subrogation status, and the certificate holder's name and address.

ACORD 25 carries a standard disclaimer that it confers no rights on the certificate holder and does not amend the underlying policy. This disclaimer matters: a certificate incorrectly showing additional insured status does not create additional insured coverage. The endorsement must exist at the policy level.

ACORD 27 - Evidence of Property Insurance (Personal/Residential)

ACORD 27 is used for personal and residential property coverage. It provides evidence of insurance for mortgagees, lenders, and loss payees who require proof that a residential property is insured. ACORD 27 shows the property insured, coverage type, policy limits, mortgagee/loss payee information, and cancellation notice provisions.

ACORD 27 is distinct from ACORD 28 in its intended use: personal lines residential property. Homeowners, dwelling fire, and personal condo policies use ACORD 27. A lender requiring evidence of homeowners coverage on a residential mortgage property should receive an ACORD 27.

ACORD 28 - Evidence of Commercial Property Insurance

ACORD 28 is the commercial property equivalent of ACORD 27. It documents commercial property coverage for lenders, mortgagees, loss payees, and certificate holders who need evidence that a commercial building or business personal property is insured.

The key distinction between ACORD 27 and ACORD 28 is not the value of the property - it is the coverage type. A $20 million residential apartment building covered under a personal dwelling policy would use ACORD 27. A $500,000 commercial office building covered under a commercial property policy uses ACORD 28.

ACORD 28 shows: the insurer, named insured, property description, coverage form type (occurrence-form or equivalent), policy limits, coinsurance percentage, mortgagee/loss payee information, and additional interests. For certificate-of-property-insurance purposes, ACORD 28 is the standard form for commercial real estate transactions.

ACORD 75 - Insurance Binder

ACORD 75 is the standard binder form used to provide temporary evidence of coverage while a formal policy is being issued. A binder confirms that coverage is in force as of a specified date, pending policy issuance. ACORD 75 includes the same core fields as the certificate forms - insurer, named insured, coverage lines, limits - but is explicitly labeled as a binder rather than a certificate.

Binders are time-limited, typically 30–90 days. They are used most commonly in commercial lines for mid-term account placements, acquisitions, or construction starts where coverage must begin before the underwriting process is complete.

ACORD 125 - Commercial Insurance Application

ACORD 125 is the core commercial lines application form. It captures the applicant's general information: entity type, business description, ownership structure, prior coverage history, prior losses (5-year loss runs), and the signature section. ACORD 125 alone does not contain enough information to quote or bind any specific line of coverage - it is the header document to which line-specific supplement forms are attached.

ACORD 126 - Commercial General Liability Section

ACORD 126 supplements ACORD 125 with the information needed to underwrite a commercial general liability (CGL) policy. It captures operations description, premises information, independent contractors, subcontracted operations, completed operations history, and the policy structure requested (occurrence-form vs. claims-made-form).

The claims-made-form vs. occurrence-form selection on ACORD 126 is one of the most consequential coverage decisions in commercial lines. Occurrence policies cover claims arising from incidents during the policy period, regardless of when the claim is filed. Claims-made policies cover claims both arising from incidents and filed during the policy period. ACORD 126 requires a clear selection, and agencies should confirm the selection matches the client's risk management needs before submission.

ACORD 130 - Workers Compensation Application

ACORD 130 is the workers compensation application supplement. It captures employer information, class codes, payroll by classification, state(s) of operation, number of employees, and loss history. Workers compensation underwriting is heavily dependent on the accuracy of ACORD 130 - incorrect class codes or understated payroll are the primary sources of workers compensation policy audit adjustments.

ACORD 130 includes fields for each state in which the insured has employees. Multi-state employers must list operations in every state. Omitting a state from ACORD 130 typically means that state is excluded from the workers compensation policy - creating an uninsured exposure.

ACORD 140 - Commercial Property Application

ACORD 140 supplements ACORD 125 for commercial property underwriting. It captures building construction type, year built, occupancy, fire protection, sprinkler systems, square footage, replacement cost value, business personal property, loss of income coverage requested, and coinsurance percentage. ACORD 140 also includes fields for reporting vacant or seasonal occupancies - which affect coverage availability and pricing significantly.

ACORD 27 vs ACORD 28: Which to Use

The correct form depends on the coverage type, not the property value or size.

Common error: issuing an ACORD 27 for a commercial property policy. This typically occurs when a producer defaults to the same form for all property evidence requests without checking the policy type. A commercial lender receiving ACORD 27 for a commercial property policy may reject it because the form does not cover commercial property coinsurance or business income fields.

How ACORD Forms Are Being Digitized

ACORD's Digital Transformation program, launched formally in 2017 and accelerating through 2024–2026, replaces static PDF form exchange with structured data exchange through ACORD XML standards and API-based integrations.

ACORD XML. ACORD developed an XML data schema that maps every field in the ACORD form library to a structured data element. Instead of exchanging PDFs, agencies and carriers exchange XML messages containing the same information - but in machine-readable format. An ACORD 125 XML submission automatically populates the carrier's underwriting system without manual data entry.

IVANS integration. IVANS (now part of Applied Systems) is the primary data exchange network connecting agencies with carrier systems. IVANS Download allows carriers to push policy data - declarations pages, endorsements, cancellations - directly into agency management systems using ACORD XML standards. IVANS Upload enables agencies to submit applications and endorsement requests directly from their management system to carrier portals.

API-based form data exchange. ACORD's more recent standards work focuses on REST APIs that allow real-time data exchange between agency management systems, carrier policy administration systems, and third-party tools. BrokerageAudit's ACORD Form Library uses these standards to populate and validate form data against active policy records before any document is generated.

Digital certificates. Several carrier platforms (including those operated by Chubb, Travelers, and Hartford) now issue digital certificates with blockchain-verified policy data. These certificates cannot be altered after issuance - a significant improvement over PDF certificates, which can be edited manually.

The pace of digitization varies by carrier and form type. Certificates of insurance (ACORD 25, 27, 28) are the furthest along in digital exchange. Commercial applications (ACORD 125 series) still rely heavily on PDF submission in the surplus lines and specialty markets.

How ACORD Standards Facilitate Agency-Carrier Data Exchange

The core value of ACORD standards is that they eliminate custom translation between trading partners. Without common standards, an agency submitting an application to 10 carriers would need to map their internal data to 10 different carrier schemas. With ACORD XML, the agency maps their data once - to the ACORD schema - and every ACORD-compliant carrier can receive it.

For agencies, this means: applications submitted to multiple carriers from a single data entry. For carriers, it means: applications received in a format that maps directly to their policy administration system. For policyholders, it means: faster quoting, fewer duplicate data entry errors, and consistent coverage documentation.

The ACORD standards also cover claims (First Notice of Loss messages), policy endorsements (Change Request transactions), and billing (invoice and payment messages). A fully ACORD-integrated agency can process most routine transactions without exporting and re-keying data between systems.

Frequently Asked Questions

What are the most commonly used ACORD forms?

The most commonly used ACORD forms are: ACORD 25 (Certificate of Liability Insurance), ACORD 27 (Evidence of Property Insurance - personal), ACORD 28 (Evidence of Property Insurance - commercial), ACORD 75 (Binder), ACORD 125 (Commercial Insurance Application), ACORD 126 (Commercial General Liability supplement), ACORD 130 (Workers Compensation Application), and ACORD 140 (Commercial Property Application). ACORD 25 alone is issued millions of times per year across commercial lines accounts.

How are ACORD forms being digitized?

ACORD's Digital Transformation program replaces static PDF forms with ACORD XML data exchange and REST API integrations. Agencies and carriers that adopt ACORD XML standards exchange structured data instead of PDFs, enabling automatic population of carrier systems from agency submissions. IVANS Download and Upload handle policy data exchange for most major carriers. Digital certificates with blockchain verification are now issued by Chubb, Travelers, and Hartford on certain account types.

What is the ACORD 126 form used for?

ACORD 126 is the Commercial General Liability section supplement to ACORD 125. It captures the operations description, premises details, independent contractor exposure, subcontracted work, completed operations history, and the policy structure selection (occurrence vs. claims-made). ACORD 126 is submitted alongside ACORD 125 whenever a commercial general liability policy is being quoted or bound.

When do you use ACORD 27 vs ACORD 28?

Use ACORD 27 for personal and residential property coverage - homeowners, dwelling fire, personal condo. Use ACORD 28 for commercial property coverage - office buildings, retail, industrial, mixed-use commercial. The distinction is the coverage type, not the property value. A residential rental property covered under a personal dwelling fire policy uses ACORD 27. The same property covered under a commercial landlord policy uses ACORD 28.

What is the ACORD 130 workers compensation form?

ACORD 130 is the Workers Compensation Application supplement to ACORD 125. It captures employer classification codes, payroll by class code, states of operation, employee count, and 5-year loss history. Workers compensation premiums are based on payroll by class code, making accurate ACORD 130 completion critical to both initial pricing and post-policy audit results. Multi-state employers must list all states of operation or risk having states excluded from the policy.

How do ACORD standards facilitate data exchange between agencies and carriers?

ACORD XML standards define a common data schema that maps every field in the ACORD form library to a structured data element. Agencies submit ACORD XML messages to carriers, which map directly to carrier policy administration systems without manual re-keying. Carriers send ACORD XML policy data back to agencies through IVANS Download, populating agency management systems automatically. This eliminates the need for custom data mapping between each agency-carrier pair and reduces data entry errors across the transaction lifecycle.
