An ACORD 25 is the standard certificate of liability insurance. You issue one by pulling the insured, carriers, policy numbers, limits and dates from the policy on file, adding the certificate holder and any required wording, and checking it before it goes out. It proves coverage exists. It does not change the policy.
Every agency knows the scene. A contractor needs a certificate by 3 p.m. for a job site, the CSR is on another call, the policy sits in one place and the endorsement in another. The volume of requests is not the real problem. The problem is collecting the same information again, every single time.
This guide covers what the ACORD 25 does and does not do, how to issue one step by step, the mistakes that force a re-issue, a Florida detail that matters for workers' comp, and a simple way to clear the daily backlog.
What an ACORD 25 does, and what it does not
The ACORD 25 is organized in sections: the producer (your agency), the insured, the insurers with their NAIC codes, the coverages with policy numbers, dates and limits, a description of operations, and the certificate holder (Heron Data, ACORD 25 form guide, vendor).
The wording on the form itself is the part to explain to clients and holders. A standard ACORD 25 states that it "is issued as a matter of information only and confers no rights upon the certificate holder," and that if the holder is an additional insured, "the policy(ies) must be endorsed" (text of a standard ACORD 25, sample on the City of Seattle site).
In plain words: the certificate is a snapshot. The endorsement is what creates rights. A holder who needs additional insured status needs the endorsement on the policy, and typing "additional insured" in the description box does not replace it.
How to issue an ACORD 25, step by step
- Confirm the request. Who is asking, for which contract, and what coverages and limits does that contract require? Ask for the insurance clause or the holder's requirements sheet before you start, not after the first rejection.
- Pull the insured's legal name and mailing address from the client record. It must match the policy, not the way the client introduces the business on the phone.
- List each carrier with its NAIC number. This is how the recipient verifies who stands behind each policy.
- Fill each line from the policy. For general liability, mark occurrence or claims-made and enter the limits. For auto, umbrella and workers' comp, enter the policy number, the effective and expiration dates, and the limits. Check that the dates match each policy.
- Mark additional insured and waiver of subrogation only where the policy has the endorsement. Never mark either one "to be safe."
- Write the description of operations with what is true and documented: operations, locations, and the endorsements that apply.
- Enter the certificate holder's exact legal name and full mailing address. A typo here can turn into a claims dispute later.
- Review, sign and send. An authorized person at the agency signs. Many agencies send the certificate to the client first and then forward it to the holder.
Steps 2 to 8 follow the walkthrough published by the CSR training company Total CSR, a vendor. The order is common practice, so adapt it to your agency's approval rules.
Five mistakes that force a re-issue
- Holder name or address off by a few characters. The holder's system rejects it and you start over.
- Dates that do not match the policies. A certificate showing an expired policy is worse than no certificate.
- Additional insured marked without the endorsement. The certificate promises something the policy does not deliver.
- Waiver of subrogation marked "yes" by default. Only mark it when it actually applies.
- Limits copied from last year's certificate. If the GL renewed with new limits, the old numbers travel for months.
