A certificate of insurance is a one-page summary of your policy that your broker issues on request, usually within a few hours and usually at no charge. Clients, landlords, and general contractors ask for it constantly. It is the most requested document in small business insurance and the most widely misunderstood.
The misunderstanding is worth being precise about, because it runs in both directions. Businesses handing over a certificate often think it has given the client something it has not. Businesses receiving one often think they are protected when they are not. The document itself tells you this, in small print most people never read.
What the ACORD 25 Actually Says About Itself
Nearly every certificate you will see is an ACORD 25, the standard industry form. Across the top sits a disclaimer stating, in substance, that the certificate is issued as a matter of information only, confers no rights on the holder, and does not amend, extend, or alter the coverage in the policy.
That is not boilerplate hedging. It is a statement of law in several states. New York, for example, has long held that the "information only" language exists because insurance law prohibits an insurer from making a contract of insurance other than as expressed in the policy itself — a certificate cannot grant coverage the policy does not contain, no matter what is typed into it.
The form goes further and tells the reader what to do about it. Below the disclaimer it notes that if the certificate holder is an additional insured, the policy must actually contain additional insured provisions or be endorsed; that if subrogation is waived, an endorsement may be required; and that a statement on the certificate does not substitute for either. In ACORD's own words, the certificate does not confer rights in lieu of such endorsements.
The practical translation: a certificate is a receipt, not a contract. It tells you a policy existed on the day it was printed, with those limits, expiring on that date. Everything else on it is a description of endorsements that either exist in the policy or do not.
Reading One in Ninety Seconds
Whether you are issuing or receiving, the same handful of fields carry all the weight:
| Field | What to check | Common failure |
|---|---|---|
| Named insured | Exact legal entity, matching the contract signatory | DBA on the certificate, LLC on the contract — different entities |
| Policy effective/expiry dates | Covers the whole engagement, not just today | Certificate valid today, policy expires mid-project |
| Each occurrence / general aggregate | Meets or exceeds the contract minimum | Aggregate already partly eroded by earlier claims — invisible here |
| Coverage type boxes | Occurrence vs claims-made ticked as required | Claims-made supplied where occurrence was demanded |
| Description of operations | Matches the actual scope of work | Certificate for "general contracting" on a roofing job |
| Additional insured / subrogation boxes | Ticked and backed by named endorsement forms | Box ticked, no endorsement in the policy |
| Certificate holder | Correct entity and address | Confused with additional insured — see below |
The most consequential of these is the last pair. Being listed as certificate holder means you receive a copy of the document. It grants no coverage whatsoever. Being an additional insured means the policy has been endorsed to cover you. They are printed inches apart on the same form and mean entirely different things — we cover that distinction fully in additional insured vs certificate holder.
What to Ask For If You Are the One Receiving It
If a certificate is the only thing you hold, you are relying on a document that disclaims its own reliability. When the stakes justify it, ask for two more things:
- Copies of the endorsements themselves. If the contract required additional insured status with completed operations, ask for the endorsement pages — typically CG 20 10 and CG 20 37 or their equivalents. This is the only way to confirm the coverage exists. Vendors and their brokers supply these routinely; a broker who resists is telling you something.
- Confirmation the aggregate is intact. A general aggregate is shared across the policy year and across every project the vendor is working on. A certificate showing $2,000,000 aggregate says nothing about how much of it is still available. On a large engagement, ask whether a per-project aggregate endorsement is in place.
Fraudulent and altered certificates also exist, and they are easy to produce because the form is a Word-editable template in practice. If a certificate arrives directly from the vendor rather than from their broker, and the amount at stake is meaningful, it is reasonable to ask that the broker send it directly or to call the agency listed on the form.
Getting One Issued Without Delays
If you are the business supplying the certificate, the process is simple and the failure modes are predictable. Send your broker the certificate holder's exact legal name and address, the required limits, the specific endorsements the contract names, the project or scope description, and the contract clause itself. Most brokers turn this around same day, and there is normally no charge for the certificate.
Requests get rejected for a small set of repeat reasons, nearly all of them clerical:
- The named insured does not exactly match the contracting entity.
- Limits fall short of the contract minimum.
- An endorsement was requested on the certificate but never added to the policy — which is a real coverage gap, not a paperwork problem.
- The description of operations does not match the work being performed.
- The policy expires before the project ends.
Two things are worth building into your routine. First, certificates expire when the policy does, and on multi-year engagements a lapsed certificate can hold up payment for work already completed — diary the renewal alongside the policy. Second, if the contract asks for an endorsement your policy does not carry, the fix is to add the endorsement, not to have the certificate say so. A certificate describing coverage that is not in the policy protects nobody and can create an expensive argument later.
Bottom Line
A certificate of insurance proves a policy existed on the date it was issued. It does not create coverage, extend coverage, or bind the insurer to anything, and the form says so on its face. Treat it as the starting point of verification rather than the end of it: check the entity name, dates, limits and scope in ninety seconds, and when the exposure justifies it, ask for the endorsement pages that actually carry the coverage.

Frequently Asked Questions
What is a certificate of insurance and what does it prove?
A certificate of insurance is a one-page summary, almost always on the standard ACORD 25 form, showing that a policy was in force on the date it was issued with the limits and expiry date listed. It proves a policy existed at that moment. It does not create, extend, or alter coverage - the form's own disclaimer states it is issued as a matter of information only and confers no rights on the holder.
Does a certificate of insurance give me coverage?
No. If you are listed only as the certificate holder, you receive a copy of the document and nothing more. Coverage comes from the policy and from endorsements added to it. The ACORD form itself notes that if the holder is an additional insured, the policy must contain additional insured provisions or be endorsed, and that a statement on the certificate does not substitute for that endorsement.
How do I get a certificate of insurance?
Request it from your insurance broker. Send them the certificate holder's exact legal name and address, the required limits, the specific endorsements the contract names, a description of the work, and ideally the contract clause itself. Most brokers issue it the same day and there is normally no charge.
Why was my certificate of insurance rejected?
Usually for one of five reasons: the named insured does not exactly match the contracting entity, the limits fall short of the contract minimum, an endorsement was described on the certificate but never actually added to the policy, the description of operations does not match the work, or the policy expires before the project ends. Most are clerical, but the missing endorsement is a genuine coverage gap rather than a paperwork issue.
Should I ask for more than a certificate when hiring a vendor?
When the exposure justifies it, yes. Ask for copies of the endorsement pages themselves, typically CG 20 10 and CG 20 37 for additional insured status including completed operations, since that is the only way to confirm the coverage exists. It is also worth asking whether the general aggregate is intact, because it is shared across the policy year and every project the vendor is running.
Do certificates of insurance expire?
Yes - a certificate is valid only as long as the underlying policy, and it shows that expiry date on its face. On multi-year contracts this matters practically, because a lapsed certificate can hold up payment for work already completed. Diary the renewal date alongside the policy rather than waiting for the client to notice.
