Is a COI the Same as a Declaration Page?

Are a COI and a Declaration Page the Same Thing?

A certificate of insurance and a declaration page serve entirely different purposes. One document is designed specifically for you to verify coverage, while the other exists for the policyholder to understand what they purchased.

What Is a Declaration Page?

A declaration page (often called a "dec page") is the summary page that comes with an actual insurance policy. It's the document policyholders receive from their insurance provider that spells out exactly what they bought: coverage limits, policy period, monthly premiums, named insureds, and specific endorsements.

Dec pages are internal documents between the policyholder and their insurance company. They contain detailed policy limits and coverage details, but they don't address third-party requirements like additional insured status. A contractor's dec page might show $2 million in general liability coverage, but it won't confirm that your company is protected as an additional insured.

What Is a Certificate of Insurance?

A certificate of insurance is a standardized form (typically ACORD 25) created specifically to verify insurance coverage for third parties. When you're hiring an independent contractor or bringing vendors onto a construction site, you need confirmation that their insurance protects you if something goes wrong.

An insurance certificate includes essential key details: types of insurance coverage provided (like general liability, workers’ compensation, auto liability insurance, and umbrella/excess liability), coverage limits, expiration date information, and whether your company is listed as an additional insured. Unlike dec pages, COIs are issued by the insurance agent or broker. To learn more about how to read a certificate of insurance, read our complete guide!

Can I Show My Declaration Page as Proof of Insurance?

While a declaration page proves an active insurance policy exists, it doesn't fulfill what most contractual agreements require. Contracts need confirmation of additional insured endorsements and specific liability limits that meet thresholds. These are things a dec page doesn't address.

Why COIs Are the Industry Standard for Vendor Compliance

Certificates of insurance became the standard because they translate insurance policies into information that matters for business relationships. When you're managing financial risk across multiple vendors, you need a consistent format that lets you quickly verify coverage meets your requirements.

The construction insurance industry and small business owners rely on insurance certificates because they streamline compliance tracking. Rather than reviewing full policy documents (which can exceed 50 pages), COIs distill essential information into one page. Organizations that implement automated COI tracking consistently report reclaiming 15-20 hours per week that were previously spent on manual certificate management, leaving them with more time for actual project work.

What Should You Do If a Vendor Sends a Dec Page?

When a vendor sends a declaration page instead of a certificate, they might genuinely not understand the difference. Your response should be straightforward: "Thanks for sending your insurance information. To meet our vendor requirements, I need a certificate of insurance (COI) that shows [your company name] listed as an additional insured for general liability coverage. It’s a standard request, so your insurance agent can generate this certificate quickly."

This removes awkwardness by treating it as a simple documentation matter. Most insurance agents can issue COIs within hours.

What Is Another Name for a Certificate of Insurance?

You'll hear several terms used interchangeably in the insurance industry. "COI" is the most common abbreviation, while some people call it an "insurance certificate" or simply a "certificate." In formal contractual agreements, you might see "evidence of insurance" or "proof of coverage," which typically means a certificate of insurance.

Occasionally, especially when working with nonprofit organizations or other third parties, you'll encounter requests for "insurance documentation." When you see these phrases, assume they mean a proper certificate of insurance unless explicitly stated otherwise. If there's ambiguity, always ask for clarification before projects begin: it's easier to confirm requirements upfront than to discover coverage gaps after property damage incidents occur.
