Verifying Blanket Additional Insured Practical steps for risk teams

This guide provides a practical workflow for verifying blanket additional insured endorsements on Certificates of Insurance, helping teams confirm that vendor coverage appropriately extends to their organization.

How do you verify blanket additional insured status?

Verify blanket additional insured status by checking for specific endorsement forms on the COI that grant coverage via written contract. Cross-reference these forms against the vendor’s actual policy requirements, ensuring your organization meets the contract criteria. Tools like /resources/additional-insured-vs-certificate-holder help standardize these critical review steps.

Verification Workflow

Steps to Verify Blanket Coverage

  1. 1

    Confirm Contractual Obligation

    Ensure your service agreement explicitly requires the vendor to maintain additional insured status via a blanket endorsement.

  2. 2

    Identify Endorsement Forms

    Review the 'Description of Operations' section for references to specific blanket additional insured forms, such as CG 20 26 or similar.

  3. 3

    Request Underlying Documentation

    Since a COI is not a policy, request the actual endorsement page if your risk threshold necessitates absolute confirmation of coverage extension.

  4. 4

    Log and Audit

    Use /vendor-compliance-management to document that the specific forms were reviewed and match your organization's minimum requirements.

Risk Review

What to Flag During Review

  • Missing 'Written Contract' Language

    If the policy requires a written contract but one is not on file for that specific job, coverage may not apply.

  • Excluded Operations

    Check if certain types of work are explicitly excluded from the blanket endorsement's scope.

  • Limits Mismatch

    Ensure that even with blanket status, the primary and excess limits meet your minimum contractual requirements.

Terminology

Key Definitions

Blanket Endorsement

An endorsement that applies additional insured status to any party for whom the named insured is contractually obligated to provide such status.

Certificate Holder

The party receiving the certificate, who should be listed on the document, but is not automatically an additional insured based on that fact alone.
