How to Read a Certificate of Insurance (ACORD 25): A Field-by-Field Walkthrough
A field-by-field walkthrough of the ACORD 25 certificate of insurance — what each section means, the disclaimer everyone skips, and the three places certificates go wrong.

Diamond Flooring Starts Next Week
2 coverage gaps—we've reached out and resolved this before work begins.
- Emailed Vendor
- Verified with Insurance Broker
- Updated new COI in system
Diamond Flooring starts next week. Travis finds that the general liability limit needs an increase and the additional insured is not listed, emails the vendor, verifies coverage with the insurance broker, and updates the new COI in the system before work begins.
A certificate of insurance — almost always an ACORD 25 form — is a one-page summary of someone's liability coverage, issued by their insurance agent as a courtesy to whoever asked for proof. Reading one takes two minutes once you know where to look. Reading one correctly means also knowing what it can't tell you, which is printed right on the form and skipped by nearly everyone.
Start with the disclaimer (seriously)
The top of every ACORD 25: "This certificate is issued as a matter of information only and confers no rights upon the certificate holder. This certificate does not affirmatively or negatively amend, extend or alter the coverage afforded by the policies below."
Translated: everything on this page is a report about coverage, not coverage. If the lease or contract requires additional insured status or a waiver of subrogation, the proof is an endorsement attached behind the certificate — never the certificate alone. Hold that thought; it reframes every field below.
The fields, top to bottom
Producer. The insurance agency that issued the certificate. This is who you contact for corrections — not the insured, whose role is mostly forwarding your email to this box.
Insured. The name and address of the policyholder. Check it character by character against the entity you contracted with. "Acme Builders LLC" on the contract and "Acme Builders Inc." on the certificate is a finding, not a typo — coverage follows the named insured.
Insurer(s) affording coverage. The carriers, lettered A, B, C…, matched to each policy line below. Worth a glance for carrier quality (A.M. Best rating) on high-stakes contracts.
The coverage grid. One row per policy — this is the body of the form:
- Type of insurance: general liability (check occurrence vs claims-made — occurrence is standard for most requirements), auto, umbrella/excess, workers' comp.
- ADDL INSD / SUBR WVD columns: small "Y" boxes indicating additional insured status and subrogation waiver. A "Y" here is the agent's claim — the endorsement behind the cert is the proof. Y-without-endorsement is one of the most common gaps in real stacks.
- Policy number and effective/expiration dates: check every row's dates separately. GL and umbrella renew on different dates, and a current GL above a lapsed umbrella passes a casual glance.
- Limits: per occurrence, aggregate, and per-line limits. Compare against the contract requirement, not against "looks normal."
Description of operations. The free-text box where agents type things like "Certificate holder is named additional insured as required by written contract." Per the disclaimer above, this box amends nothing. It's context, not coverage — treat any protection that exists only here as absent until you see the form.
Certificate holder. Who the certificate was issued to — your entity, exact name and address. Being the holder gets you this piece of paper and (maybe) notice of cancellation. It does not make you covered; that's what additional insured status is for, and the difference has its own explainer.
Cancellation. Modern ACORD 25s promise notice only "in accordance with the policy provisions" — which frequently means no notice to you at all. If your contract requires 30 days' notice, that too lives in an endorsement.
The three places certificates go wrong
Pattern across thousands of real certificates: (1) the description box doing the endorsements' job — protections claimed in free text with no forms attached; (2) entity mismatches — wrong LLC, misspelled name, holding company instead of contracting party; (3) split expirations — one policy line current, another lapsed. All three pass an expiration-date check, which is why tracking dates isn't verifying coverage.
FAQ
Is an ACORD 25 the same as a certificate of insurance? Effectively yes — ACORD 25 is the standard form for liability certificates in the US. (ACORD 24 covers property; you'll see both.)
How do I know if a COI is valid? Check insured name, dates on every line, limits against your requirement — then require the endorsements attached. For high-stakes contracts, confirm directly with the producer; certificates can be (and have been) forged.
Who issues a COI? The insured's agent or broker — the "Producer." Which is why corrections should go straight to them.
