If you've signed a commercial lease, hired a contractor, or contracted with a motor carrier, you've received an ACORD 25 — the standard Certificate of Liability Insurance. It's a one-page form that confirms a business has commercial general liability (and often auto and workers' comp) coverage in force. Despite being one of the most-exchanged documents in U.S. business, almost nobody knows how to read it properly. Here's the box-by-box guide.
What an ACORD 25 actually is
ACORD (Association for Cooperative Operations Research and Development) publishes the standardized insurance forms used industry-wide. ACORD 25 specifically is the certificate of liability insurance form — proof that a policy is in force. It's NOT the policy itself; it's a summary issued by the producer (insurance agent) on the carrier's behalf. The certificate is for informational purposes only and does not amend, extend, or alter the underlying policy.
Box-by-box walkthrough
Top-right: certificate date
The date the certificate was issued. This is NOT the policy effective date — it's the print date. A certificate dated months ago might or might not still be valid; verify the policy effective/expiration dates in the coverage section below.
Producer block (top-left)
The insurance agent or broker who issued the certificate. Includes the agency name, address, phone, and contact name. This is who you call to verify the certificate or to make changes. If a contract requires a 30-day cancellation notice and the producer's contact info is missing or stale, you have no path to enforce that requirement.
Insured block
The named insured — the business or person the policy covers. Verify the legal name matches the entity you contracted with exactly. A common red flag: you contracted with 'ABC Construction LLC' but the certificate shows 'ABC Construction Services Inc.' — different entity, the certificate doesn't protect you.
Insurers affording coverage
Lists the carrier(s) issuing the policies, each with a NAIC code. Lookup each carrier's AM Best rating at ambest.com — anything below A- is a yellow flag for contracts requiring solvent backing. Multiple carriers commonly appear because GL, auto, and WC might be from different companies.
Coverages table — the meat of the certificate
The big middle section. Each row is a policy type with its coverage details. The standard rows are commercial general liability (CGL), commercial automobile, umbrella/excess, and workers' compensation. For each row check:
- Type of insurance — is the coverage type even present? A contract requiring auto coverage isn't satisfied by a certificate showing only GL.
- Insurer letter — matches one of the insurers listed at the top.
- Policy number — confirm against what the producer claims.
- Effective date — when coverage starts.
- Expiration date — when coverage ends. If this date is before the project ends, you need a renewal certificate before the original expires.
- Limits — the maximum the policy will pay. For CGL: each-occurrence limit (typically $1M), general aggregate (typically $2M), products-completed operations aggregate (typically $2M), personal & advertising injury (typically $1M).
Description of operations / locations / vehicles
A free-text field for additional information. This is where additional-insured language is written, special endorsement codes are noted (CG 20 10 for blanket additional insured on CGL, CG 20 37 for products-completed operations), waiver of subrogation references, and project-specific descriptions. If your contract requires you to be named as an additional insured and this box doesn't mention it, the certificate doesn't satisfy your contract.
Certificate holder block
Who the certificate is issued to — usually you. Verify your name and address are correct. If the certificate names a different party, the producer issued it to someone else.
Cancellation language and signature
The bottom of the form has standard cancellation language and a signature line. Modern ACORD 25 cancellation language reads: 'Should any of the above described policies be cancelled before the expiration date thereof, notice will be delivered in accordance with the policy provisions.' That's intentionally vague — actual notice obligations are in the underlying policy. The signature is the producer's authorized representative.
Common red flags
- Insured name doesn't match the entity in your contract — certificate doesn't cover the party you're working with.
- No additional-insured endorsement listed in description box when your contract requires one — you're not actually protected.
- Effective date in the future or expiration date already past — coverage isn't currently in force.
- Limits below what your contract requires — non-compliant.
- Carrier AM Best rating below A- — solvency risk.
- Producer's contact info missing — no path to verify or enforce.
- Hand-written edits or strikethroughs — the certificate should be reprinted clean. Edits are often unauthorized.
- PDF lacks signature or shows 'Authorized Signature' as plain text without a signed stamp — possibly fraudulent.
How to verify a suspicious certificate
If something looks off: 1) Call the producer (the agent/broker listed at the top) directly using a number you find independently — not the one on the certificate, which could be faked. 2) Ask them to confirm the policy is in force, that you're listed as additional insured per your contract, and that the limits shown are accurate. 3) For high-value contracts, request a copy of the actual additional-insured endorsement (CG 20 10 or similar form number) as a PDF, not just the certificate.
How to request changes
If a certificate is missing additional-insured language, has wrong limits, or names the wrong party, contact the producer (not the insured directly) and request a revised certificate. Most producers can re-issue same-day. For additional-insured changes, the producer must verify the underlying policy actually grants that status — they can't just add it to the certificate without an endorsement.
