Key Sections of a COI

Producer Information: This lists the insurance agency or broker. It shows their name, address, and contact details. This is who sent the COI. You can call them with questions.
Insured Information: This shows the name and address of the business covered. Check that it matches the business you are working with. If it's your COI, make sure your business name is correct.
Insurer(s) Affording Coverage: This lists the insurance companies. Each policy may have a different insurer. For example, your general liability might be with one company. Your commercial auto could be with another.
Policy Information: This part details each insurance policy. It usually includes:
- Policy Number: A unique ID for the policy.
- Policy Effective Date: When coverage started.
- Policy Expiration Date: When coverage ends.
- Coverage Type: The kind of insurance. Common types are:
  - General Liability: Covers injury or damage to others.
  - Commercial Auto: Covers vehicles used for business.
  - Workers' Compensation: Covers employee injuries on the job.
  - Professional Liability (E&O): Covers claims of mistakes in professional services.
  - Commercial Property: Covers your business's physical assets.
  - Business Owner's Policy (BOP): Often combines general liability and commercial property. The California Department of Insurance explains a BOP covers property and general liability.
Limits of Liability: This is a very important section. It shows the most an insurer will pay for a covered claim. You will see different limits:
- Per Occurrence: The most paid for one single event.
- General Aggregate: The total most paid over the policy year.
- Products-Completed Operations Aggregate: Total most for claims from your products or finished work.
- Personal & Advertising Injury: Covers claims like libel or slander. Always compare these limits to what your contract requires.
Description of Operations / Locations / Vehicles / Special Items: This area gives more specific details. It might describe the project or location. It often notes special additions. This is where you find additional insured status on COI and waiver of subrogation on certificate of insurance details.
Certificate Holder: This is the party who asked for the COI. It could be your client, landlord, or a main contractor. Their name and address should be correct here.
Cancellation Notice: This says how much warning the insurer gives before canceling a policy. It is often 30 days for not paying. It might be 10 days for not renewing.

What to Look for on a COI for Contractual Compliance

When you get a COI, check it closely. Your goal is to make sure it meets all contract terms. This is your COI contractual compliance checklist.

Your COI Review Checklist

Correct Insured Name and Address: Is the business name on the COI correct? Is the address accurate? A wrong name or address could make the COI invalid for your contract.
Active Policy Dates: Check that the policy is current. The start date should be before your contract begins. The end date should go past your contract's expected finish. If it ends during your contract, you will need a new COI.
Required Coverage Types: Does the COI list all needed insurance types? Your contract might ask for General Liability, Commercial Auto, or Workers' Compensation. Make sure each one is there.
Sufficient Limits: Compare the "Limits of Liability" to your contract. If your contract needs $1 million in General Liability, the COI must show at least that much. Lower limits mean the COI does not meet your terms.
Additional Insured Status: Many contracts ask for you to be an "additional insured." This gives you some protection under their policy. Look for this wording in the "Description of Operations" box. Or it might be on an attached paper called an endorsement. It could say, "Your Company is named as an additional insured." This is a key part of what to look for on a COI.
Waiver of Subrogation: A waiver of subrogation on certificate of insurance is also common. This stops the insurer from asking you for money back. If your contract needs it, ensure it is on the COI. This is often in the "Description of Operations" or on an endorsement.
Proper Certificate Holder: Confirm your business name and address are correct. They should be in the "Certificate Holder" section.
