Proving that someone has business insurance (like, say, a third party or independent contractor before they begin working with you) is most simply done through a certificate of insurance. Also known as a COI, these are documents that come straight from an insurer that verifies someone’s coverage. COIs are hugely important for several reasons that we’ll get into, and it’s imperative to review them carefully before finalizing them.
However, as you may have already figured, the minimum insurance requirements and regulations that govern certificates of insurance differ from state to state. Because insurance is regulated at the state level in the U.S., each state has the authority to establish its own rules for insurance companies and policyholders.
As a result, businesses and insurance companies alike must keep up and comply with the laws and regulations of each state where they do business, which includes the specific requirements governing certificates of insurance. Failure to comply with these requirements can result in penalties, fines, or other legal consequences, so it’s important to know the rules wherever you’re operating.
Follow along in our official statewide guide where we break down what COIs are used for and how different states regulate them.

Before we get into state-by-state comparisons, let’s get back to the basics. A COI, or certificate of insurance, is used for several purposes, the main one being that it serves as a certification of insurance coverage for a specific policy period. It provides quick and easily digestible evidence that a policyholder does indeed have the insurance coverage that they claim.
Here are a few other things that COIs are used for:
To obtain a certificate of insurance, you’ll need to request it from the third party that you’re working with. For them, it’ll go something like this:
They’ll start by contacting their insurance company or broker and letting them know that they need one. They’ll then provide their insurer with some information, including the name and contact information of the entity requesting the certificate (you), the type of certificate needed, the policy number, the agreed-upon coverage limits, the effective dates and expiration date of the policy, the names and addresses of any additional insureds, etc.
Once they’ve provided all of the necessary information, they can officially request the certificate from their insurance company or broker. The insurer will deliver the certificate as a printed hard copy or in an electronic format and the whole process typically takes up to a few business days. Finally, after reviewing and approving the COI, they’ll provide it to you to prove their coverage.
There are numerous types of COIs, and the requirements for each type can differ by state. It essential for businesses to be able to keep track of all types of COIs. A few common types companies should be aware of are certificates of liability insurance, certificates of workers’ compensation insurance, and certificates automobile liability insurance.
As is the case with many other legal issues, each state has its own requirements when it comes to governing certificates of insurance. The requirements can vary depending on both the type of insurance and, of course, the state where the policy is issued.
It’s important to note that laws and regulations can be changed at any time, so it is essential for you to stay on top of the different relevant state laws and regulations that may affect your COI management. In other words, conduct research on the different COI requirements for all of the states in which your company conducts business.
Since it would be a very lengthy and potentially ever-changing ordeal to list all of the slightly differing rules for each state, here are the current requirements of COIs by state for the top ten most populated states in the United States:
Again, requirements can vary depending on the state and the type of insurance policy you’re working with. While we have listed some of the individual state laws and regulatory directives, these are just a few examples of COI regulations as of the moment this blog was written. To ensure that a COI meets the necessary requirements in your state, be sure to consult with an attorney or insurance professional.

Adding a certificate holder to an insurance policy is not the same thing as adding someone to the policy (like an additional insured, for example). Instead, a certificate holder is the third party who requests and receives the COI and can use it to verify and provide proof of coverage. So, you become a certificate holder once you request a COI from a third party, and your name and contact information is put on the document.
To go about adding an entity to a COI as the certificate holder, the contractor or third party you need coverage verification from will first need to ask their insurance company or agent for a certificate of insurance in order to add a certificate holder to the policy. The policyholder will then specify which party requested the certificate. As the business hiring them, you will be the certificate holder in this case, and you should be sure that they know about all of your required terms and conditions.
From there, they’ll give their insurance company all the needed information about the certificate holder, including your name, address, and relationship to them. They’ll also need to provide information about the policy itself, such as the start and end dates of the coverage. Finally, their insurance provider will deliver the certificate to you with your information officially listed on the policy!
