Certificate of Insurance vs. Endorsements: Employer Guide
By Matt Layson • 07/10/2025
When COIs and Endorsements Come into Play
Employers who work with contractors, vendors, or third-party service providers often come across terms like Certificate of Insurance (COI) and endorsements. However, while these documents are both essential in the insurance world, they serve different purposes. Understanding these differences is crucial to safeguarding your business against potential risks and liabilities.
Do you know if a COI is enough, or should you request an endorsement? This blog aims to unravel the key differences between COIs and endorsements, explain their significance, and offer practical advice for employers.
Understanding Certificates of Insurance (COI)
A Certificate of Insurance (COI) is a summary document issued by an insurance company to confirm that a business or individual has active insurance coverage. COIs contain crucial details that you should be aware of:
- **Policyholder’s Name**: Identifies the individual or entity the policy covers.
- **Coverage Types**: Lists the types of insurance such as general liability, workers’ compensation, auto, etc.
- **Policy Limits and Effective Dates**: Specifies the coverage limits and the period during which the policy is valid.
- **Insurer’s Contact Details**: Provides information on who to contact in the event of a claim or query.
Why is this important? Requesting a COI before bringing a third party on board ensures they have the necessary coverage in place, thus reducing your liability risks.
Exploring Endorsements (Policy Modifications)
An endorsement, also known as a rider, is a modification to an existing insurance policy that alters the coverage terms, either by adding, removing, or changing them. Here are some common endorsements:
- **Increasing Policy Limits**: Raises existing coverage limits for better protection.
- **Adding an Additional Insured**: Includes the employer on the contractor’s policy for extended coverage.
- **Expanding Protection**: Addresses additional risks that a standard policy may not cover.
The importance of endorsements lies in their ability to customize coverage to align with specific needs, especially when additional protection is required beyond what the standard policy provides.
Key Differences at a Glance
To help employers make informed decisions, it's beneficial to compare COIs and endorsements:
- A COI serves as proof of existing insurance without altering policy terms.
- An endorsement legally modifies a policy by adding or removing coverage.
Employer Best Practices
To ensure proper coverage and protect your business, consider these actionable steps:
- Always request a COI before engaging contractors or vendors.
- Review COI details carefully, including policy limits and expiration dates.
- If additional coverage is needed, request an endorsement to ensure proper protection.
Understanding the roles of COIs and endorsements in business contracts is crucial. While a COI confirms coverage, an endorsement ensures that coverage meets specific needs. Thoroughly reviewing your insurance requirements and consulting with a qualified insurance professional are key steps before hiring third parties.
