COI request letters that actually get certificates back
Most COI requests fail because they're vague: 'please send your insurance certificate' gets you a certificate face with no endorsements, the wrong holder name, or a policy that expires mid-project — and then you're requesting again. A good request tells the vendor's AGENT exactly what to issue. Copy these.
Template 1 — new vendor
Subject: Certificate of insurance needed before work begins — [Vendor name]
Hi [Vendor], before we can schedule work, we need a certificate of insurance (ACORD 25) from your insurance agent showing: (1) Commercial General Liability with limits of at least $1,000,000 each occurrence / $2,000,000 aggregate; (2) [Auto liability $1,000,000 CSL / Workers Compensation — statutory / Umbrella $X, as applicable]; (3) [Company legal name] named as additional insured on a CG 20 10 (ongoing operations) and CG 20 37 (completed operations) basis, with the endorsement pages attached to the certificate; (4) a waiver of subrogation in our favor; (5) coverage written as primary and non-contributory. Certificate holder: [Company legal name, address]. Your agent can upload it directly here — no account needed: [upload link]. Forwarding this email to your agent is usually the fastest path.
Template 2 — renewal (30 days out)
Subject: Insurance certificate on file expires [date] — renewal needed
Hi [Vendor], the certificate we have on file expires on [date]. To keep you eligible for work without interruption, please have your agent issue an updated ACORD 25 with the same requirements as before (additional insured endorsements CG 20 10/CG 20 37 attached, waiver of subrogation, primary & non-contributory). Upload link for your agent: [upload link].
Template 3 — certificate received but non-compliant
Subject: Certificate received — two items missing before we can approve
Hi [Vendor], thanks for the certificate. Two items need correcting before we can mark you compliant: [e.g. 'the additional insured endorsement pages are not attached — the checked box alone doesn't evidence the endorsement' / 'GL each-occurrence shows $500,000; our contract requires $1,000,000']. Please forward this to your agent — it's typically a five-minute re-issue on their side. Upload the corrected certificate here: [upload link].
Why these work
They're written to be forwarded to the agent, they name the exact ISO endorsement forms (agents respond to form numbers, not adjectives), and they include a no-login upload path so the certificate doesn't die in an inbox. Automating this sequence — 30/14/7 days before expiry, to the vendor and the producing agent — is most of what COI tracking software does.
Frequently asked questions
Who should the request actually go to?
Send it to the vendor but write it for their insurance agent — the agent is the only one who can issue the certificate. The producer block of any prior certificate has the agent's direct email; chasing them directly cuts days off renewals.
How long does it take to get a COI back?
A same-day turnaround is normal when the request is specific and reaches the agent; vague requests routed through the vendor commonly take one to two weeks of back-and-forth.
