Additional Insured vs Named Insured — What's The Difference?
A named insured owns the policy; an additional insured gets limited coverage added by endorsement.
What it actually does
The "named insured" is the party that owns the policy — the entity listed on the declarations page. It has the full bundle of rights and duties: it pays the premium, controls the policy, receives notices, and is covered for its own liability subject to the policy terms.
An "additional insured" (AI) is a party added by endorsement (such as CG 20 10 or CG 20 38) who receives *limited* coverage under someone else's policy — typically only for liability connected to the named insured's work for them. An AI doesn't own the policy, can't change it, isn't guaranteed notice of cancellation unless separately arranged, and only has the coverage the specific endorsement grants.
This distinction trips up COI review constantly. Being named as an additional insured on a sub's policy is not the same as the sub being insured, and it's far narrower than being a named insured. Verify which status a form actually confers — and remember that an AI's coverage is shaped (and often capped) by the endorsement language and the contract.
Verification checklist
- 01Identify whether you're being added as an additional insured (by endorsement) versus listed as a named insured.
- 02Confirm the AI endorsement (CG 20 10/37/38) is attached, not just referenced on the COI.
- 03Understand the AI coverage is limited to the named insured's work for you and may be capped.
- 04Arrange separately for notice of cancellation if you need it — AI status doesn't guarantee it.
Common mistakes
- ·Treating additional-insured status as equivalent to owning coverage under the policy.
- ·Assuming an AI automatically gets notice of cancellation.
Frequently asked questions
Is an additional insured the same as a named insured?
No. A named insured owns and controls the policy with full rights; an additional insured gets limited coverage added by endorsement, usually only for the named insured's work for them.
Does additional-insured status include cancellation notice?
Not automatically. Notice of cancellation to an additional insured must generally be arranged separately.
