What Is a Master Insurance Policy?

In small business insurance, “master policy” refers to the combining of several locations or operations under a single policy for the same insured or insureds.

How Does a Master Insurance Policy Work?

A master insurance policy (sometimes called a group or program policy) is a comprehensive policy established by the insurance company that many individual businesses can join. The master policy outlines the coverage terms, limits, and rules, including who can qualify for coverage under the policy.

When you enroll and pay your fee (aka premium), you’re added as an insured under the master policy. You get your own Certificate of Insurance (COI, sometimes called an ACORD COI) and can typically add additional insureds.

It’s how programs keep insurance quick, affordable, and standardized for lots of small or mobile businesses.

At a glance:

  • One policy → many enrolled businesses
  • Keeps costs lower than custom policies
  • Each business gets its own proof of insurance
  • Ideal for vendors, crafters, mobile pros
