How to Read a Certificate of Insurance

A certificate of insurance summarizes selected policy information for a particular date. It does not create rights, alter coverage, or replace the policy and endorsements. This guide explains the fields worth reviewing and when to request more documentation.

What the ACORD 25 Is — and Isn't

The ACORD 25 is a standardized one-page form your agency issues on behalf of a policyholder. It sums up the key elements of one or more policies in a format contractors, property owners, and lenders can read fast.

It is a summary, not a policy. The form states that it is issued as information only and does not amend, extend, or alter coverage. It reports selected policy information as of the issue date, but it does not establish coverage or show every exclusion and endorsement. Those answers live in the policy documents.

The Producer Box

The upper-left corner names the producer — the agency or brokerage that issued the certificate for the insured. The producer isn't the carrier. It's the licensed agent who placed the coverage and can issue certificates, confirm endorsements, and field coverage questions. You'll see an agency name, address, and contact number.

Something looks off — a limit short, a date lapsed, an endorsement missing — call the producer. On high-stakes deals, check that the producer details match what you'd expect from that vendor. Certificates can be altered after issue. Inconsistent formatting, or a producer name you don't recognize, earns a direct call to verify.

Named Insured and Carrier Fields

The insured section names the named insured — the legal entity that bought the coverage. Match it to the legal name in your contract. If your agreement is with Martinez Plumbing LLC but the certificate reads Martinez Plumbing, you may not be looking at the same entity.

Below that, the insurer section lists the actual carriers, each tagged with a letter code that maps to the coverage rows below. Every carrier also shows an NAIC number — the National Association of Insurance Commissioners identifier. Use it to confirm the carrier is licensed in the relevant state.

Coverage Types, Policy Numbers, and Dates

The body of the form runs by coverage type — rows for General Liability, Automobile Liability, Umbrella or Excess Liability, Workers Compensation, and more. Each shows the policy number, effective and expiration dates, and limits.

Policy dates are the field people skip most. A certificate showing an expired policy is no proof of current coverage. Confirm the policy period runs through your contract start date — and through the completion date on longer jobs.

Limits earn a field-by-field check against your contract schedule. General Liability shows four: each occurrence, general aggregate, products and completed operations aggregate, and personal and advertising injury. A contract requiring $2 million per occurrence calls for a different structure than the common $1 million per occurrence form. Workers Compensation shows Employer's Liability limits separately. Confirm each against your subcontract requirements.

The Description of Operations Box

Below the coverage grid sits the Description of Operations / Locations / Vehicles box — a free-text area where the producer notes project-specific requirements, endorsement claims, and special conditions. It deserves far more attention than it gets.

A well-filled box confirms three things: additional insured status on a primary and non-contributory basis, waiver of subrogation, and notice of cancellation. Each ties back to a real policy provision.

Example scenario: A property management company requires vendors to name the property owner as an additional insured. A vendor hands over a certificate with the property owner listed as certificate holder — but the description box says nothing about additional insured status. A loss happens. The carrier denies the tender because no additional insured endorsement exists in the policy. The certificate didn't create the endorsement. An empty description box, when your contract requires specific endorsements, is your cue to request a revised certificate.

The Certificate Holder Field

The lower-left box names the certificate holder — the party the certificate is addressed to. That listing isn't the same as being an additional insured. Holder status means you receive the document, and under many forms it means you receive cancellation notice. It doesn't extend coverage.

Coverage extends only when an additional insured endorsement is actually attached to the policy. A general contractor who spots their name in the holder box may assume they're protected. Whether they are turns on the policy endorsements, not the holder field. For certificate requests and endorsement management, email service@blisins.com.

A Practical Review Sequence

When a certificate lands, run the fields in order. Confirm the named insured matches the legal entity in your contract. Note the producer contact for follow-up. Check the carriers are recognized and admitted in the relevant state. Check each policy's effective and expiration dates against your project timeline. Compare each coverage line's limits to your contract schedule. Then read the description-of-operations box in full.

Something doesn't match — a short limit, a passed date, a missing endorsement — the fix is simple. The insured calls their broker, who adjusts the policy and reissues. If you're the one issuing certificates, confirm your policy carries the endorsements it references before it goes out. A certificate stating coverage the policy doesn't hold becomes a problem the moment a claim exposes the gap. For policies placed through BLIS, request certificates by emailing service@blisins.com.
