Contracts often say “send a COI naming us additional insured.” People then type a name into the certificate holder box and hope. Those are different jobs.

Direct answer
Certificate holder ≈ who gets a copy of the ACORD form. Additional insured ≈ a status created by policy endorsement (or qualifying blanket wording). If the contract requires additional insured, the COI alone is usually not enough—see the endorsement.

Frequently asked questions
Is a certificate holder the same as an additional insured?+
No. A certificate holder is typically the party listed to receive a copy of the certificate of insurance. Additional insured status usually requires an endorsement (or blanket additional-insured wording) on the policy—not merely a name in the certificate-holder box.
Does an ACORD certificate change the policy?+
Generally no. Certificates are evidence snapshots. The policy and endorsements control. If a contract requires additional insured status, ask for the endorsement or confirmed blanket wording—not only a COI PDF.
