Additional Insured vs. Certificate Holder on a COI
Both names appear on a certificate of insurance, but only one of them may actually gain coverage under the policy.
What a certificate of insurance is
A certificate of insurance, or COI, is a summary document that shows a policy exists, its limits, and its dates. It is evidence of coverage, not the policy itself, and the COI alone generally does not grant anyone coverage.
Two roles commonly appear on a COI, and they are frequently confused: the certificate holder and the additional insured.
The two roles side by side
- Certificate holder. Simply the party receiving the certificate as proof that the named insured carries coverage. Being listed here generally provides no coverage to the holder — it is a notification role.
- Additional insured. A party added to the policy itself by endorsement. When properly endorsed, an additional insured may be afforded certain coverage under the named insured’s policy, in the event of a covered claim, typically for liability arising from the named insured’s work.
Why the difference matters
If a contract requires you to be named as an additional insured but you are only listed as a certificate holder, you may not have the protection you think you do. The endorsement, not the certificate, is what extends coverage.
This commonly comes up when venues, general contractors, landlords, or clients require additional insured status before letting work begin. Asking only for a certificate that lists you as the holder usually does not satisfy that requirement.
How to confirm what you actually have
Read the contract language carefully: it generally specifies whether you must be a certificate holder, an additional insured, or both. Then confirm the additional insured endorsement is actually on the policy, since the COI is just a snapshot.
A licensed insurance professional can confirm whether the correct endorsement is in place and matches what your agreement requires.
Frequently asked questions
Does being a certificate holder give me coverage?
Generally no. A certificate holder simply receives proof that a policy exists. Coverage for another party usually requires being added as an additional insured by endorsement.
Why would someone require additional insured status?
Because it may extend certain coverage to them under your policy for liability arising from your work. Venues, clients, and general contractors commonly require it before work begins.
Can the certificate itself add me as additional insured?
No. The certificate only summarizes the policy. Additional insured status comes from an endorsement on the policy, which the certificate may then reference.
