How to Read a Certificate of Insurance (COI): A Step-by-Step Guide

If you've ever opened a Certificate of Insurance and thought: 'What does any of this mean?' — you're not alone.

COIs look complicated, but they're simply proof that someone actually has insurance. And if you're running an event, knowing how to read one could save you from massive liability.

What Is a COI?

A Certificate of Insurance is a one-page document that proves: what coverage exists, how much coverage, who is insured, and when coverage expires.

It does NOT create coverage. It only proves coverage exists.

Step-by-Step Breakdown

Named Insured — This must match your vendor exactly. If the business name is different → red flag.

Policy Dates — Check expiration. Common mistake: vendor's insurance expired last week. No active date = no coverage.

Limits — Look for: $1M per occurrence, $2M aggregate (standard minimum). Lower? Ask for more.

Additional Insured Section — Your event or venue should be listed here. Without this, you're not protected under their policy.

Coverage Types to Confirm — General liability, workers comp, auto (if driving), liquor (if serving).

What to Do If Something's Missing

Never 'hope for the best.' Request: updated certificate, higher limits, or endorsements.

Pro Tip

Collect COIs at least 2–3 weeks before the event, not the day of.
