Certificate holder vs. additional insured
These two terms get treated as interchangeable in vendor paperwork, and the confusion is expensive: one gives you actual insurance coverage, the other gives you a piece of paper.
A CERTIFICATE HOLDER is simply the party a certificate of insurance is addressed to. It proves the vendor had coverage on the day the certificate was issued — and nothing more. An ADDITIONAL INSURED is a party added to the vendor's policy itself by endorsement, entitled to defense and coverage under that policy for liability arising from the vendor's work.
What being a certificate holder gets you
Evidence, not protection. The ACORD 25 says it plainly: the certificate 'confers no rights upon the certificate holder.' If the vendor's employee injures a visitor and you get sued, being a certificate holder gives you no claim on the vendor's policy. You may not even be notified if the policy cancels — the pre-2010 notice language was gutted, and modern certificates promise only that the insurer will 'endeavor to' notify.
What being an additional insured gets you
A seat inside the vendor's policy. Their insurer owes YOU a defense and indemnity for covered claims arising out of the vendor's operations — which is what your contract's insurance clause was trying to accomplish in the first place. The status only exists if an additional insured endorsement (commonly CG 20 10 for ongoing operations, CG 20 37 for completed operations) is actually attached to the policy — the ADDL INSD checkbox on the certificate is an assertion, not the endorsement.
The compliance checklist
When a contract requires additional insured status, verification means:
- The endorsement form (or a blanket endorsement plus your written contract) is attached behind the certificate — not just a checked box.
- The named party matches your exact legal entity.
- Ongoing AND completed operations forms are present when the work warrants it.
- You appear as certificate holder too — that's how you get the paper trail and renewal certificates.
Frequently asked questions
Can you be both certificate holder and additional insured?
Yes, and in most vendor relationships you should be: certificate holder to receive the evidence, additional insured to receive the coverage.
Does being a certificate holder mean I'm notified if the policy cancels?
Not reliably. Modern ACORD language only says the insurer will 'endeavor to' deliver notice. Continuous tracking — not the certificate — is what catches mid-term cancellations.
What are the risks of being only a certificate holder?
You may believe you're protected when you're not: no defense, no indemnity, no reliable cancellation notice. If the contract meant to shift risk to the vendor's insurance, holder-only status quietly defeats it.
