What Is a COI and How Do I Get One?

A Certificate of Insurance for events is a simple way to confirm that vendors, contractors, or event planners involved in your event carry active event insurance and liability insurance coverage, which is also a common requirement for a COI in contracting. Most venues require a COI to verify that event liability insurance and special event insurance are in place to protect against risks such as property damage, injuries, or unexpected disruptions. While a COI serves as proof of insurance, understanding which policies to request—such as one day event insurance or event cancellation insurance—and how to clearly communicate those requirements can be confusing without the right guidance.

You can request a COI directly from your vendors or contractors by sharing the venue’s insurance requirements and asking their insurance company to issue the certificate.

When Do You Need to Request a COI for an Event?

You request a COI for an event when:

  • Your event involves a venue, vendor, or contractor
  • Outside vendors or services are part of your event
  • Vendors or contractors work on-site, and the venue requires proof
  • Third-party help is supporting any part of your event
  • Anyone outside your team is working at your event

What Insurance Do I Need to Run an Event?

Most events need different types of insurance. Knowing what each covers helps you talk to your vendors about your requirements.

  • Event liability insurance, a form of general liability protection, gives you and the venue peace of mind by covering accidental injuries or property damage during the event.
  • Workers’ compensation insurance covers bodily injuries that happen during setup, takedown, or work at the event. 
  • Auto liability insurance protects the event when vendor or contractor vehicles are involved on-site.
  • Umbrella or excess liability insurance ensures vendors can meet higher venue insurance limits without leaving any gaps in protection.

Where to Get Insurance for an Event?

Knowing where to get insurance gives you the confidence to move forward with a COI request process. You can get it from:

  • Special event insurance providers
  • Licensed insurance brokers and agents
  • Traditional insurance companies
  • Direct online dashboards of insurance platforms
  • Existing business insurer

How Do You Request a COI From Event Vendors?

Requesting a COI from vendors becomes much easier when vendors know exactly what the venue expects. Most event vendors are familiar with the process and appreciate information beforehand. Here’s how to ask for a certificate of insurance:

  1. Ask the vendor directly for their insurance certificate
  2. Explain your event insurance coverage expectations upfront
  3. Share the venue’s requirements
  4. Request that they obtain the COI from their insurance provider
  5. Review the COI to ensure it meets the venue’s guidelines
  6. Submit the final COI to the venue for accuracy and approvals

What Should You Include in Your COI Request?

A COI request letter provides vendors with the details they need to meet the venue’s insurance requirements, so they can send the right paperwork. This saves you from the last-minute insurance questions or delays. You can include the following in your COI request:

  • Name of the venue or the event location
  • Certificate holder name and address
  • Coverage types
  • Scope of coverage
  • Additional insured for events
  • Event dates (Include setup, the event itself, and wrap-up dates)
  • Any special endorsements or requirements
  • Deadline for submission
  • COI delivery instructions

How Do You Verify a COI Once You Receive It?

Go through the certificate so you feel confident the coverage meets your event’s needs. Knowing how to read a certificate of insurance helps you confirm every requirement. Make sure the event policy number is active and that the coverage limit matches the venue's requirements. The venue should be listed as an additional insured if needed. A quick check of the effective and expiration dates, or the policy period, confirms that you meet all the details.

What Happens If a Vendor's COI Is Missing or Expired?

If a vendor’s COI is missing any information or is out of date, you can request a fresh certificate from the insurer to begin work on-site. Most insurers issue updated COIs quickly, and sharing your venue’s requirements in advance helps them issue the certificate without delay.

How Much Does an Event COI Cost?

A COI is free. Vendors can request it from their insurer at no extra cost, as long as their policy is active. The only expense comes from the policy they already carry.
