What Is a COI Request Form?

A Certificate of Insurance (COI) request form asks a vendor, contractor, or service provider to share their COI. It takes the guesswork out of the process by laying out what you need and providing the vendor a simple checklist to follow. You’re no longer chasing missing documents or sorting out incomplete COIs. The insurance request form sets clear expectations so your vendor can send the right insurance details from the start.

‍

What Is the Purpose of the COI?

A Certificate of Insurance removes uncertainty and empowers you to take confident steps forward. It:

• Gives you confidence that your vendor or contractor has the right COI vs liability insurance coverage they need for the work.
• Shows the key coverage types involved in most jobs, including commercial general liability, workers’ compensation, auto liability, and umbrella/excess liability insurance.
• Provides business insurance policy information, such as coverage type, amount, and effective and expiration dates.
• Protects your business against any financial risk that would otherwise rest on you, like third-party insurance issues or bodily injury claims.
• Helps you stay aligned with the coverage requirements tied to the work.
• Supports a more open, trusting working relationship.

When Would I Need a COI

Knowing when to ask for proof of insurance is stressful and overwhelming. But in certain situations, how to ask for a COI is simply part of doing business. You’ll need one for:

• Signing new client contracts
• Working with your vendors or service partners
• Starting engagements with enterprise or government teams
• Leasing equipment, event venues, or office space
• Meeting the insurance expectations set by your business partners, investors, or stakeholders

What a COI Request Form Includes

‍

A COI request form outlines the specific insurance information you need a vendor to provide before work begins. It typically includes the legal name of the insured business, the insurance company issuing the policy, and the policy numbers associated with each type of coverage. The form also specifies required insurance coverage limits, such as general liability insurance, workers’ compensation coverage, and any additional policies tied to the scope of work.

In addition, a COI request form details the effective and expiration dates of the insurance policy to confirm coverage is active for the duration of the project. It may require the requesting business to be listed as an additional insured and note any special endorsements or liability coverage requirements. By clearly documenting these elements upfront, the COI request form helps ensure the insurance certificate meets contractual and compliance standards while reducing risk for both parties.

‍

Why a COI Request Form Is Used

‍

A COI request form is used to formally document and communicate insurance requirements before a vendor or contractor begins work. It ensures all parties understand what insurance coverage is required, which insurance company must issue the policy, and what liability coverage or workers’ compensation coverage applies to the specific job. By standardizing this request, businesses reduce misunderstandings and avoid delays caused by incomplete or incorrect insurance certificates.

‍

What Happens If You Don't Request a COI Before Work Starts?

Skipping the COI before your work starts leaves you vulnerable and exposed to insurance liabilities. Mishaps without an active insurance policy shift the financial burden to your company rather than to the vendor’s insurance. Requesting COIs early gives your project a kickstart. This step prevents unnecessary confusion and helps everyone know their responsibilities.

‍

When Should You Ask for a Certificate of Insurance?

COI requests are essential whenever a vendor’s work introduces potential risk to your business. Understanding what is a COI request form helps small business owners ensure that a certificate of insurance, also referred to as an insurance certificate, is collected before work begins. These requests confirm that an insurance company has issued an active insurance policy with the required insurance coverage, including liability insurance, liability coverage, and workers compensation coverage. COI request forms are especially important for routine maintenance, work involving property or equipment, jobs in shared or rented spaces, and any projects governed by contracts or regulatory insurance requirements.

How Do You Know What Coverage Limits to Ask For?

Coverage should match the kind of work you’re bringing in and the risks it comes with. Knowing how to read a certificate of insurance helps you align coverage with the scope of the work. Some jobs carry less risk. Others come with more risk. Electrical jobs, roofing, or anything related to heavy equipment require more coverage to match the risks involved.

Most teams work with about $1 million per claim and $2 million in total as general liability insurance. The claim amount is significant, but it’s a common number across the industry. They provide both you and the vendor with real protection, making it easier to move ahead without worry.

‍

What Information Should You Include in Your COI Request?

The COI request letter: 

• Lists the coverage types and minimum policy limits needed for the job.
• Includes your business name and address as the certificate holder.
• Describes the project, location, and the dates the insurance should cover.
• Calls out any required endorsements, such as adding your company as additional insured.
• Explains where the vendor should send the certificate and when you need it, so the project starts on schedule.

‍

What If a Vendor Pushes Back or Delays Providing Their COI?

Vendors don’t always send their COI right away. Sometimes their insurance provider or insurance agent is slow to issue it. Other times, they fail to realize why you’re asking for it in the first place. 

Explaining how the COI protects both sides moves the process forward. If the vendor needs more time, check in and ask whether they’ve requested the document from the insurance company and when they expect to receive it. For higher-risk work or tighter schedules, begin the project once you receive the COI.
