What Is a Certificate of Insurance (COI)?

A Certificate of Insurance (COI) is like a superhero cape for your business - it's proof that you have insurance coverage and can save the day in various situations. Whether you're renting out a property, hiring contractors, hosting events, or providing services to clients - having proof of insurance coverage is often mandatory.

A COI is a security blanket that provides assurance to all involved in any agreement or transaction. It provides details about the type and extent of your insurance policy without revealing confidential information about the insured party.

What Information Does a COI Include?

  • Type and amount of coverage: The COI lists the types and amounts of coverage included in your policy, such as general liability, workers' compensation, and auto liability. This gives assurance to others about the level of protection they can expect from any claims arising due to accidents or mishaps related to your business operations.

  • Name(s) of Insured: This includes the names of both legal entities like corporations and LLCs, along with individuals who are covered under this policy.

  • Coverage period: This specifies when exactly the coverage starts and when it expires.

  • Endorsements/Exclusions: If there are any specific additions (endorsements) or exclusions made on standard policies, then those will also be mentioned here.

In essence, a Certificate Of Insurance (COI) acts as an official summary showcasing what protections are offered by one's current insurance policies. It not only helps build trust but also ensures transparency between all parties involved.

Who Needs a Certificate of Insurance?

Organizing a venture, hosting an occurrence, or engaging as a contractor? Evidence of insurance coverage might be requested at some point, necessitating the presentation of a Certificate of Insurance (COI). Enter the Certificate of Insurance (COI).

A COI serves as tangible evidence that your business has adequate insurance protection in place. It's not just for large corporations either - small businesses and even individuals may need one too.


All types of businesses can benefit from having a COI on hand. Whether it's to meet contractual obligations with clients or suppliers, comply with local regulations, or simply instill confidence in potential customers - having proof of appropriate insurance coverage is crucial.

Event Vendors

Event vendors, such as caterers and equipment rental companies often require a COI before they will agree to work at your venue. This protects them against liability claims should anything go wrong during the event.


In many cases, contractors must show their clients a COI before beginning any work on-site. The certificate provides assurance that if something were to happen while they're performing their duties (like property damage or injury), there would be an active policy covering these risks.


  • Requirements for obtaining and maintaining a COI can vary widely depending on industry standards and state laws, so always check what applies specifically to your situation.

  • You can obtain this document from your insurance agent or broker by submitting a request along with any applicable fees.

What's in a Certificate of Insurance?

A COI is not merely a sheet of paper; rather, it serves as evidence that your enterprise has the required insurance to safeguard itself from potential risks and liabilities. Here's what you can expect to find in a COI:

Sample COI
Sample COI

Name of the Insured

The insured's name is the first item present on a COI, whether it belongs to an individual or organization. This confirms who exactly is covered under the policy.

Type and Amount of Coverage

The COI details what type(s) and how much coverage you carry. It may indicate whether you have general liability, workers' compensation, commercial auto, professional liability, or other types of insurance policies in place. The limits for each type are also listed to show how much protection these policies provide.

Policy Period

This refers to when your policy starts and ends - essentially showing how long you're protected under this specific plan.

Endorsements or Exclusions

An endorsement adds, deletes, excludes, or changes insurance coverage while exclusions specify what isn't covered by your policy. These might include additional insureds like partners or investors who need protection too; waivers such as Waiver Of Subrogation, where one party agrees not to seek damages from another in case something goes wrong; and conditions like Primary Non-Contributory arrangements which determine whose insurer pays first if there's an incident involving multiple parties.

Remember: A well-documented COI provides transparency between all involved parties - making sure everyone knows their rights & responsibilities.

How to Get a Certificate of Insurance for Your Business

As a business proprietor, obtaining insurance to safeguard your operations is essential. To obtain proof of your insurance coverage, a Certificate of Insurance (COI) is required. Here's how to get one:

Step 1: Find an Insurance Agent or Broker

Don't know where to start? Reach out to an insurance agent or broker. They can help you identify the right type of coverage based on your specific needs and industry requirements.

Step 2: Provide Detailed Information

When applying for a COI, you'll need to provide detailed information about your business, such as its location, number of employees, and nature of work performed. Your insurance provider will use this data to assess risk levels and determine policy premiums.

Step 3: Check for Fees

Most insurance brokers don't charge fees for obtaining a COI. However, it's always best practice to ask about any potential costs upfront before proceeding with an application.

Step 4: Wait for the Issuance

The issuance timeframe varies depending on several factors, including the complexity of your business operations and response times from underwriters. Typically, it takes anywhere between 24-48 hours for issuing the certificate.

Remember, having valid insurance isn't just good sense, it's often mandatory by law or contract stipulations. So make sure you not only get insured but also ensure timely renewal to avoid any gaps in coverage that could potentially expose your company to unnecessary risks.

What Are the Benefits of Having a Certificate of Insurance?

As a business owner, a Certificate of Insurance (COI) can offer several key benefits that enhance your risk management strategy and ensure compliance with regulations.

Protection Against Liability Claims

A COI provides protection against potential liability claims. If an accident or mishap occurs related to your business operations, having insurance coverage verified by a COI can help protect your company from costly legal fees and damage awards.

Evidence of Compliance

A COI serves as evidence that you have met insurance requirements set by clients, landlords, or regulatory bodies. This proof helps maintain trust in your business relationships and ensures smooth operation without interruption due to non-compliance issues.

Risk Management Tool

Carrying valid insurance coverage indicated on a COI acts as an effective risk management tool for businesses. It allows companies to transfer certain risks associated with their operations onto the insurer, providing financial security in case unexpected events occur.


It's important not just to obtain but also to manage these certificates effectively. Solutions like Coi-Comply simplifies tracking, verifying, and managing all COIs, ensuring they are up-to-date and minimizing exposure to risks. Remember, a certificate does not alter the terms of the policy nor provide additional insured status unless specified through endorsements such as Additional Insured Endorsement or Waiver Of Subrogation Endorsement among others. Understanding what each endorsement means will be crucial in maximizing the benefits offered by your Certificate Of Insurance.

Understanding Insurance Endorsements

Insurance endorsements are documents that modify an insurance policy's coverage. They can add, delete, exclude, or alter the scope of where and when your coverages apply. Here are three common types of endorsements:

  • Additional Insured: This adds a person or organization as an insured under the policy at the request of the named insured. [source]

  • Waiver of Subrogation: This waives the insurer's right to recover the money they paid on a claim from a negligent third party. [source]

  • Primary Non-Contributory: This endorsement ensures that this policy pays out claims first, regardless of any other policies that could potentially cover the claim too. [source]

Consulting with an experienced risk management professional can help you understand these endorsements better and how they impact your business operations. They can guide you through each term's implications and help ensure you're adequately protected against potential risks associated with running a business.

A Certificate Of Insurance (COI) often includes these endorsements. Therefore, understanding them helps ensure compliance with risk management regulations while protecting your business interests effectively.

Quick Recap

What is a Certificate of Insurance (COI) and When Do You Need One?

A Certificate of Insurance (COI) is a document that proves a business has insurance coverage and provides important details about the type and amount of coverage, as well as any additional insureds.

Business owners who work with vendors, contractors, or clients may need to obtain a COI to protect themselves from liability and potential lawsuits or damages.

To obtain a COI, business owners can request one from their insurance provider or agent, and having one can provide peace of mind.
