A vendor additional insured (AI) is a third-party entity added to your insurance policy, typically an event organizer or venue.
You’ve probably been asked to add an additional insured (AI) to your vendor insurance policy. But what does that actually mean for you, and how does it affect your coverage?
Understanding additional insured status helps you navigate your coverage the next time it’s required.
What is Additional Insured (AI) Status?
When you add someone as an AI to your policy, you’re extending a portion of your coverage to them, and they are receiving “additional insured status.”
This means their business information will be listed on your vendor Certificate of Insurance (COI) and share the same coverage benefits in the case of a claim caused by you that may impact their business.
Why Do I Have to Add AIs?
You’ll typically add someone as an AI because you’re working with them in some capacity, like attending their event as a vendor, working on their property, or selling products in their store or at their event.
Many entities will require vendors to list them as an AI before they can attend events, sign contracts, or do business together.
The additional insured wants to limit their risks and avoid being financially responsible for incidents that may occur due to your business. This could include:
- Bodily injury
- Property damage
- Legal fees
- Other related costs

How Does Additional Insured Status Work for Event Organizers and Venues?
When accidents strike, it’s not just your business that could be affected; the event, the venue, or even the city may be involved in a claim. That’s where additional insured (AI) coverage comes in.
You add the event and venue as AIs to your policy
🔽
Someone gets hurt at the event because they tripped over an extension cord running to your booth for power
🔽
The injured guest names you, the event, and the venue as responsible parties in a lawsuit and demands that their medical bills be paid
🔽
Your insurance covers the legal fees and medical expenses owed by you, the event, and the venue for the accident
What Does it Do to My Coverage?
Listing an additional insured won’t change your coverage, limits, or the amount of coverage allocated to you. It simply ensures the AI(s) will receive the same protections you have if they’re named in a claim.
However, your policy only covers additional insureds for incidents caused by you or your business. If the incident is not related to your actions, the additional insured may need to seek coverage elsewhere.

Who Needs to be Added as an Additional Insured?
In most cases, an additional insured will inform you that they need to be added to your policy and provide you with the necessary information.
Some common examples of an additional insured include:
✅ Associations
✅ Cities
✅ Event organizers
✅ Landlords
✅ Promoters
✅ Retailers

If you’re unsure who should be listed, it’s a good idea to reach out to the party you’re working with for clarification.
