Blanket vs. Scheduled Additional Insured: What a Client Requirement Actually Changes
Choose and verify the additional-insured mechanism when a contract requires coverage for a client, landlord, venue, or general contractor. Practical U.S. small-business guidance.
A scheduled endorsement names a specific person or organization as an additional insured. Blanket or automatic wording instead extends that status to a class of parties, but only when the policy's own stated conditions are met — and those conditions, not the word "blanket" itself, determine who actually qualifies and for what scope of work.
"Blanket" describes a mechanism, not a guarantee
A contract asking that another party be added as an additional insured rarely specifies whether the insurer should issue a named endorsement for that exact party or rely on automatic wording triggered by any qualifying written contract. Both mechanisms can technically satisfy "add my client as additional insured," but they answer different questions about who is actually covered.
Blanket wording sounds broader by name, and often is — but it is broad only within whatever class of parties and conditions the endorsement itself defines, not broad in an unlimited sense.
"Affiliates" is exactly the kind of word that tests this
A consultant signs a master services agreement requiring that the client and its affiliates be added as additional insureds. The consultant's policy contains automatic additional-insured wording, but only for the specific organization the consultant agreed in writing to insure — not automatically for every corporate affiliate that organization might have.
The word "blanket" in casual conversation about the policy does not settle whether affiliates are actually included. That is a question about the endorsement's defined class of parties, which needs to be asked directly rather than assumed from the general concept.
Scope of operations matters as much as who qualifies
Even once the right party is confirmed, the endorsement can still limit the scope of additional-insured status to specific operations, a specific project, or a specific time period. A blanket endorsement that correctly names the client's organization does not necessarily extend to every job that organization ever hires the vendor for.
What to send the broker before work begins
The exact contract clause, sent verbatim rather than paraphrased, lets the broker map it to the actual endorsement rather than guessing at what "additional insured" was meant to cover.
- The precise insurance clause from the signed contract
- Which endorsement is intended to satisfy it
- Whether the requesting party and any named affiliates actually qualify
- Whether completed operations are included or only ongoing work
- Written confirmation, kept with the job file, before work starts

Frequently asked questions
Does blanket additional-insured wording cover any client the business works with?
No. It extends coverage to a defined class of parties under stated conditions — commonly a written-contract requirement — not to every client automatically regardless of what the contract says.
If a client's contract mentions "affiliates," are those affiliates automatically covered?
Not necessarily. The endorsement's own defined class of parties controls, and affiliates are not automatically included just because the parent organization is.
Does a COI checkbox marked "additional insured" prove the status exists?
No. The checkbox reflects what the certificate preparer represents; the actual endorsement or policy provision is what creates the status.
