The Complete Guide to ACORD Forms: 125, 126, 140, 130, and 131

ACORD forms are the standardized application documents used throughout the commercial insurance industry. If you're an insurance agent submitting commercial business to carriers, you work with ACORD forms constantly. If you're a business owner applying for commercial coverage, the information you provide ends up on these forms — whether you see them directly or not.

This guide covers the five core commercial insurance ACORD forms — the 125, 126, 140, 130, and 131 — section by section. Think of it as a reference you can bookmark and come back to whenever you need a refresher on what each form contains and how to complete it correctly.

ACORD 125 is the master commercial application (required for every submission). The 126 adds GL detail, 140 adds property detail, 130 handles workers' comp, and 131 covers commercial auto. Use all relevant supplements together — the 125 alone is not a complete submission. Forms are maintained by ACORD.

What Is ACORD?

ACORD stands for the Association for Cooperative Operations Research and Development. It's a nonprofit standards organization that develops standardized forms and data standards for the insurance industry. ACORD forms create a common language between agents, brokers, carriers, and underwriters — so that when an agent in Florida submits an application to a carrier in Connecticut, both parties understand exactly what information is being provided.

Without ACORD standards, every carrier would have its own proprietary application format, and agents would need to learn a different format for each carrier they work with. ACORD forms solve this by providing universal templates that the entire industry recognizes.

The ACORD Form Numbering System

ACORD forms are numbered by line of business and function:

• 100 series: Commercial lines applications and supplements
• 200 series: Personal lines
• 300 series: Life and annuity
• 600 series: Claims and loss-related forms
• 800 series: Surplus lines and specialty

For commercial insurance agents, the forms you use most frequently are in the 100 series — particularly the 125, 126, 140, 130, and 131.

ACORD 125: Commercial Insurance Application

The ACORD 125 is the master application for commercial insurance. Think of it as the cover page and general information section for any commercial submission. Regardless of which specific coverages you're requesting, the 125 establishes the applicant's identity, operations, and basic risk characteristics.

What the ACORD 125 Contains

Section 1: Agency/Producer Information. Your agency name, address, contact information, producer code, and the agency's relationship with the carrier.

Section 2: Applicant Information. The business's legal name, DBA (doing business as), mailing address, physical address if different, phone, email, website, and FEIN (Federal Employer Identification Number).

Section 3: Business Information. This is the heart of the 125. It includes:

• Legal entity type (corporation, LLC, partnership, sole proprietor)
• Date business started
• NAICS code and SIC code
• Description of operations (in the applicant's own words)
• Annual revenue / gross sales
• Number of employees (full-time, part-time)
• Number of locations
• Business ownership details

Section 4: Prior Carrier Information. Current and prior insurance carriers for the past 3 to 5 years, including policy numbers, premiums, and whether any carrier has cancelled or non-renewed the applicant.

Section 5: Claims and Loss History. A summary of claims in the past 3 to 5 years, or a note that loss runs are attached. For how loss runs work, see our complete loss runs guide.

Section 6: Coverage Requested. A high-level indication of which coverages are being applied for — general liability, property, auto, workers' comp, umbrella/excess, professional liability, etc. The specific details for each coverage line go on the supplemental forms (126, 140, 130, 131).

Common ACORD 125 Mistakes

• Incomplete operations description. Carriers need to understand what the business actually does. "Consulting" is not enough — "IT consulting specializing in network security for healthcare organizations" gives the underwriter the context they need.
• Mismatched NAICS codes. The NAICS code should match the actual operations, not the closest-sounding category. A construction management firm is not the same NAICS as a general contractor.
• Missing loss history. Leaving the claims section blank doesn't mean "no claims" to an underwriter — it means "incomplete application." If there are no claims, state that explicitly.
• Outdated revenue figures. Use current-year projected revenue, not last year's actual. Carriers rate based on exposure during the policy period.

ACORD 126: Commercial General Liability Section

The ACORD 126 is the supplement to the 125 that provides detailed information specific to general liability coverage. If the 125 is the "who is this business," the 126 is "what GL exposure do they have."

What the ACORD 126 Contains

Coverage Details. Requested limits (per occurrence, general aggregate, products/completed operations aggregate, personal/advertising injury, damage to rented premises, medical expense). Standard ISO CGL limits are $1 million per occurrence / $2 million aggregate, though class and contract requirements often drive higher limits.

Classification Information. This is critical for GL rating. The 126 captures:

• Classification code (ISO CGL classification)
• Description of operations for each classification
• Premium basis (revenue, payroll, area, units, or other)
• Estimated exposure (the actual revenue, payroll, square footage, etc.)

Most small businesses have one or two GL classifications. Larger or diversified operations may have several.

Premises Information. For each location: address, occupancy (owned, leased, rented), square footage, building construction, number of floors, fire protection class, and specific premises-related exposures.

Products and Completed Operations. Whether the business manufactures, sells, distributes, or installs products. For contractors, completed operations coverage is essential — it covers claims arising from work after it's finished.

Additional Interests. Additional insureds, certificates of insurance requirements, and waiver of subrogation endorsements that the applicant needs. These are frequently required by clients and landlords.

Common ACORD 126 Mistakes

• Wrong classification code. Using the wrong ISO CGL class code can result in incorrect premium — and potentially a coverage gap if a claim falls outside the listed classification.
• Underreported revenue or payroll. GL premiums are typically based on revenue or payroll. Underreporting exposure to lower the premium is tempting but creates problems at audit — the carrier will charge the difference (plus audit penalties in some cases).
• Missing additional insureds. If the client has contracts requiring additional insured status for third parties, those need to be listed on the application. Adding them after binding can delay certificate issuance and contract compliance.

ACORD 140: Property Section

The ACORD 140 supplements the 125 with detailed information about commercial property coverage — the buildings, equipment, inventory, and business income you're insuring.

What the ACORD 140 Contains

Building Information. For each insured building: construction type (frame, joisted masonry, non-combustible, masonry non-combustible, fire resistive, modified fire resistive), year built, square footage, number of stories, roof type and age, wiring updates, plumbing updates, heating system, fire protection (sprinklers, alarm type).

Coverage Details. Building replacement cost, business personal property value, business income limit (if applicable), and coverage form (basic, broad, special/all-risk). The coverage form determines which perils are covered — special form is the broadest and most common for commercial property.

Valuation. Replacement cost vs. actual cash value. Most commercial property is insured on a replacement cost basis — meaning the carrier pays to replace damaged property with new property of like kind and quality, without deduction for depreciation.

Deductible. The per-occurrence deductible for property claims. Common deductibles range from $500 to $10,000 for small commercial, with higher deductibles reducing premium.

Special Property Exposures. Equipment breakdown coverage (formerly called boiler and machinery), ordinance or law coverage (important for older buildings that may require code upgrades after a loss), flood and earthquake (usually separate policies, but the 140 captures whether coverage is desired).

Business Income / Extra Expense. Coverage for lost income and extra expenses incurred while the business is shut down or operating at reduced capacity due to a covered loss. The 140 captures the estimated annual business income and the desired indemnity period (usually 12 months).

Common ACORD 140 Mistakes

• Undervalued buildings. Reporting building value below actual replacement cost leads to coinsurance penalties when a partial loss occurs. Use a replacement cost estimator rather than tax assessment or purchase price.
• Ignoring ordinance or law. Older buildings may require significant upgrades to meet current building codes after a loss. Without ordinance or law coverage, the carrier pays to restore the building to its pre-loss condition — the policyholder pays the code upgrade difference.
• Missing business income. Skipping business income coverage to save premium can be devastating. Even a small fire can shut down a business for weeks. If the business can't afford to pay rent, payroll, and other fixed expenses without revenue, business income coverage is essential.

ACORD 130: Workers' Compensation Application

The ACORD 130 is the workers' compensation supplement. WC has its own distinct rating system based on NCCI class codes (or state-specific bureau codes) and payroll, making this form particularly important for accurate premium calculation.

What the ACORD 130 Contains

States of Operation. Which states the business has employees in. Workers' comp is state-regulated, and rates, rules, and requirements vary by state. Multi-state operations need coverage in each state where employees work.

Classification and Payroll. For each employee classification:

• NCCI class code (or state bureau code in monopolistic states)
• Description of duties
• Number of employees in that class
• Estimated annual payroll

This is the core rating information. WC premiums are calculated as: (Payroll / 100) × Class Code Rate × Experience Modification Rate.

Experience Modification Rate (EMR). The applicant's EMR, which adjusts the premium based on the business's actual loss history compared to industry averages. An EMR of 1.0 means average. Below 1.0 means better-than-average loss history (lower premium). Above 1.0 means worse-than-average (higher premium).

Officers and Partners. Whether corporate officers, LLC members, and partners are included or excluded from WC coverage. State rules vary on whether officers can be excluded.

OSHA History. Whether the business has had any OSHA citations or violations. Serious or willful OSHA citations can affect carrier appetite and pricing.

Subcontractor Information. For businesses that use subcontractors: whether subcontractors carry their own WC coverage. If subcontractors don't have their own coverage, the hiring business's WC policy may be responsible for covering their injuries.

Common ACORD 130 Mistakes

• Wrong class codes. NCCI class codes must match the actual duties performed, not the job title. A "project manager" who regularly visits construction sites has a different class code than a "project manager" who works exclusively in an office.
• Misreported payroll. WC premiums are directly tied to payroll. Underreporting payroll reduces the initial premium but results in a larger audit adjustment — the carrier will collect the difference plus interest.
• Missing the EMR. If the business qualifies for an experience mod (generally businesses with annual WC premium above a state-specific threshold for three or more years), the EMR must be included. Submitting without the mod results in a manual rate quote that's usually higher than the modded rate.

ACORD 131: Commercial Automobile Section

The ACORD 131 captures detailed information about the vehicles and drivers for commercial auto coverage.

What the ACORD 131 Contains

Vehicle Schedule. For each vehicle: year, make, model, VIN, vehicle type (private passenger, light truck, medium truck, heavy truck, trailer), cost new, garaging address, and radius of operation.

Coverage Requested. Liability limits, physical damage coverage (comprehensive and collision), medical payments, uninsured/underinsured motorist, hired and non-owned auto coverage.

Driver Information. For each driver: name, date of birth, license number and state, years of driving experience, and MVR (motor vehicle record) status. Carriers evaluate driver records as a primary rating factor.

Use and Radius. How each vehicle is used (business use, service, retail, commercial), and the operating radius — local (under 50 miles), intermediate (50-200 miles), or long distance (over 200 miles). Radius affects pricing because it affects exposure.

Hired and Non-Owned Auto. Whether the business rents, leases, or uses employee-owned vehicles for business purposes. Hired and non-owned auto coverage fills the gap for vehicles the business doesn't own but uses in operations.

Common ACORD 131 Mistakes

• Incomplete vehicle schedule. All vehicles used in business operations need to be listed — including personal vehicles used for business purposes (which should trigger hired and non-owned auto discussion).
• Missing drivers. All authorized drivers need to be listed. An unlisted driver involved in an accident can create coverage disputes.
• Incorrect radius. Understating the operating radius can result in a coverage gap if a claim occurs outside the reported radius.

How ACORD Forms Connect to Quoting Efficiency

Every time an agent fills out ACORD forms manually for each carrier, the same information gets entered repeatedly — the 125 base data, the line-specific supplements, the loss history, the vehicle schedule. For an agent quoting 10 carriers, that's 10 sets of essentially the same forms, each reformatted slightly for each carrier's submission process.

This is where automation delivers the most direct time savings. Comparative raters and quoting tools pre-populate ACORD data from a single entry, then translate that data into each carrier's specific format — whether the carrier accepts ACORD forms directly, uses their own portal, or requires a proprietary application format. The field mapping layer handles the translation between your standardized data and each carrier's requirements.

For a walkthrough of how this works in practice, see our guide to what comparative raters are and our explanation of how browser automation handles carrier portals.

Beyond the Core Five: Other ACORD Forms Agents Use

While the 125, 126, 140, 130, and 131 cover the primary commercial lines, agents regularly encounter other ACORD forms:

The ACORD 25 (certificate of insurance) is probably the form agents handle most frequently outside of applications — it's the standard proof-of-coverage document that clients need for contracts, landlords, and business relationships.

Tips for Working with ACORD Forms

Be Thorough on the 125

The ACORD 125 sets the context for everything else. A well-completed 125 with a detailed operations description, accurate revenue, and complete loss history makes every subsequent carrier interaction smoother. Underwriters who get a complete 125 are more likely to quote quickly and competitively.

Match Class Codes to Operations

On both the 126 (GL classification) and 130 (WC class code), accuracy matters. If you're unsure about the right classification, check with the carrier's underwriter before submitting. A misclassified account can result in premium surprises at audit and potential coverage disputes at claim time.

Use the ACORD 101 for Context

The ACORD 101 (Additional Remarks) is an undervalued tool. Use it to explain unusual operations, provide context for loss history, describe risk improvement measures, or add any information that doesn't fit neatly into the standard form fields. Underwriters appreciate context — it helps them quote more accurately and favorably.

Keep Forms Updated

ACORD periodically updates form versions — adding fields, reorganizing sections, and reflecting regulatory changes. Make sure you're using the current version of each form. Most agency management systems update ACORD forms automatically, but agents using downloaded templates should check ACORD.org for the latest versions.

Frequently Asked Questions

What is the most important ACORD form for commercial insurance?

The ACORD 125 (Commercial Insurance Application) is the foundation — it's required for every commercial insurance submission. The line-specific supplements (126, 140, 130, 131) provide the detailed information carriers need to underwrite and rate specific coverages. Together, the 125 plus the relevant supplements constitute a complete commercial insurance application.

Do all carriers accept ACORD forms?

ACORD forms are the industry standard, and virtually all carriers accept them. However, many carriers also have their own supplemental questions or proprietary application formats that request additional information beyond what ACORD forms cover. When submitting to multiple carriers, the ACORD data serves as the foundation, with carrier-specific supplementals added as needed.

Can ACORD forms be filled out electronically?

Yes. Most agency management systems include ACORD form generation. Comparative raters pre-populate ACORD data automatically. ACORD also offers electronic form solutions through ACORD.org. Manual PDF completion is still possible but significantly less efficient than electronic pre-population — especially when submitting to multiple carriers.

How often do ACORD forms get updated?

ACORD updates form versions periodically — typically every few years for major forms, with minor updates more frequently. The form version date is printed on the bottom of each form. Carriers generally accept forms within a reasonable version range, but submitting significantly outdated forms can cause processing delays.
