Understanding the Document Everyone Requests


What a certificate of insurance actually tells you

Few insurance documents create more confusion than a certificate of insurance. Whether you are a contractor bidding a project, a landlord hiring vendors, or a business signing a new contract, chances are someone has requested a certificate before work could begin.


A certificate of insurance, often called a COI, is a document that summarizes insurance coverage in force at a specific point in time. It provides evidence of insurance but does not change policy terms or create coverage by itself.


Orrino Capital Services helps clients throughout Long Island, New York City, and surrounding markets navigate certificate requirements and documentation requests with greater confidence.


Certificates of insurance help businesses verify that vendors, contractors, tenants, and service providers maintain required coverage.


Organizations commonly request certificates before:

Why Certificates of Insurance Matter

A critical part of contracts and business relationships

  • Construction projects begin

  • Vendor contracts are finalized

  • Electrical and plumbing systems

  • Property management agreements start

  • Certain permanently installed fixtures

  • Events take place on third-party property

Without proper documentation, projects and contracts may be delayed while insurance requirements are reviewed.

Common Terms Found on a COI

Understanding the language on the certificate


Certificate Holder

The person or organization receiving proof of insurance.


Named Insured

The individual or business that owns the insurance policy.


Additional Insured

A party that may receive certain coverage protections through policy endorsement.


Policy Effective Dates

The dates coverage begins and ends.


Coverage Limits

The maximum amounts available under the policy.


Many business owners search for explanations of additional insured requirements because they are frequently requested in contracts and construction agreements.

Orrino Capital Services helps property owners evaluate these factors and determine whether flood insurance makes sense for their specific situation.


If you own rental or investment properties, reviewing real estate insurance alongside flood coverage can help create a more complete property protection strategy.

What a Certificate Does Not Do

Common misconceptions about COIs


One of the biggest misunderstandings surrounding certificates of insurance is assuming they create coverage.


A certificate generally does not:

  • Change policy terms

  • Add endorsements

  • Expand coverage

  • Property management agreements start

  • Replace the actual insurance policy

When questions arise regarding coverage obligations, policy language and endorsements remain the controlling documents.
