"Send me a certificate of insurance before we sign."


Whether you're a contractor, a vendor, a property manager, or a small business owner, a Certificate of Insurance (COI) request is one of the most common things you'll encounter in commercial relationships. But what exactly is a COI, what's actually on it, and what do you need to know before you hand one over?


Let's break it down.


What Is a Certificate of Insurance?

A Certificate of Insurance is a one-page document that summarizes your current insurance coverage. It doesn't give anyone rights under your policy — it just proves you have insurance and shows the basic details.

Think of it like a summary sheet: policy numbers, coverage types, coverage limits, effective dates, and the name of your insurer — all in one place. It's issued by your insurance agent or carrier, usually on a standard ACORD 25 form.


What Information Is on a COI?

A standard COI typically shows:

  • Named insured — The business or individual that holds the policy
  • Insurer(s) — The insurance company (or companies) providing coverage
  • Policy numbers — For each line of coverage listed
  • Coverage types — General liability, commercial auto, workers' comp, umbrella, etc.
  • Policy limits — How much each coverage pays (per occurrence, aggregate, etc.)
  • Effective and expiration dates — When coverage starts and ends
  • Certificate holder — The party requesting proof (a client, landlord, general contractor, etc.)

If required, it may also show an additional insured — meaning the requesting party has been added to your policy and has certain rights under it. This is a separate step from just issuing a COI.


Why Do Clients, Landlords, and GCs Ask for COIs?

Because they want to make sure they won't be left holding the bag.

If you're working on someone's property and cause damage, or if a worker gets injured, or if a customer slips and falls at your business — the injured party may come after your client, your landlord, or whoever hired you. A COI confirms that you carry enough insurance to cover those situations, so the requesting party doesn't have to.

Common situations where you'll be asked for a COI:

  • Signing a commercial lease
  • Being hired as a subcontractor
  • Working on a government or municipal contract
  • Participating in an event or using a venue
  • Bidding on a construction or service project
  • Onboarding with a new client or vendor


5 Things Every Texas Business Owner Should Know About COIs

1. A COI does not transfer coverage rights. It's proof of insurance — not a policy. The person who receives your COI doesn't have the right to file a claim on your policy just because they hold a certificate. For that, they'd need to be named as an additional insured on the actual policy.

2. You can usually get one same-day. When you need a COI, contact your insurance agent. At TAP Insurance, we can typically turn these around the same business day. Don't wait until the morning of a job walkthrough — give us a heads-up.

3. Clients may require specific coverage limits or endorsements. Some clients or contracts require higher-than-standard limits — say, $2 million general liability instead of $1 million. Others require you to list them as an additional insured. Make sure your policy can accommodate what your clients require before you sign a contract.

4. A COI expires when your policy expires. If your coverage lapses or you switch carriers, your certificate is no longer valid. Stay on top of your renewal dates to avoid gaps. Your clients may also require updated COIs each year.

5. Never fabricate or alter a COI. Issuing a fake COI or altering coverage amounts is insurance fraud in Texas — a serious criminal offense. It's not worth it. If you're having trouble affording coverage, call us. There are options.


What About Additional Insured Requirements?

This is where things get more specific. If a client requires you to add them as an additional insured on your general liability policy, that means they're entitled to defense and coverage under your policy for claims arising from your work. This is different from just listing them on a COI.


To add an additional insured, you typically need an endorsement on your policy — and some carriers charge for this. Before you agree to an additional insured requirement in a contract, confirm with your agent that your policy can accommodate it.


How Fast Can TAP Insurance Get You a COI?

Fast. Same business day in most cases. If you have an urgent request, give us a call or send a text — we'll get it handled.

If you're in a situation where you're losing work because you don't have the right coverage in place, let's fix that too. We can review your current policy limits and make sure you're set up to meet typical contractor and vendor requirements.


Bottom Line

A Certificate of Insurance is a simple but important document. It proves you're covered, protects the people you work with, and opens doors to contracts and commercial relationships that require proof of insurance.
