Certificate of Insurance for Contractors: What to Prepare
A certificate of insurance (COI) for contractors summarizes insurance details for a client or another recipient. Request the actual certificate from your insurance agent or insurer. To prepare, gather the recipient’s legal name and address, job details, dates and written insurance instructions.
Separate the document request from the insurance decision
A COI summarizes information about insurance. The actual policy and applicable endorsements determine coverage; requesting a document does not purchase insurance or resolve a gap. If you have no policy, tell the agent before asking for a certificate. If you have a policy, provide the client’s instructions for review rather than declaring that everything is already covered.
Organize the job around three questions: who is asking, what paperwork they requested, and when they need it. This avoids mixing a document deadline with the planned start of work. Do not treat the builder’s completed checklist as authorization to begin a project.
Build a request packet for one job
Use the business name shown on your insurance documents, the client-confirmed recipient name and mailing address, a plain-language job description, the work location, and the relevant dates. Keep recipient identity separate from requests for additional insured status. Your agent may ask for further information.
Use the contractor COI request builder to organize known details and unresolved questions. It prepares a message for your agent; it does not issue a certificate.
Contractor COI preparation checklist
Original resource: the three-part handoff worksheet
| Part | Gather | Ask if unresolved |
|---|---|---|
| Identity | Your business name and client-confirmed recipient details | Which legal entity should receive the certificate? |
| Job | Scope, city and state, work dates and document deadline | Is there a project reference or revised schedule? |
| Insurance request | Relevant client instructions and requested supporting documents | Which items need policy review or further action? |
Work through the rows before composing your message. Keep an unanswered item in your follow-up list rather than filling it with a guess. Send sensitive contracts or policy identifiers through the agent’s usual secure channel instead of a public preparation tool.

Read the visual checklist as text
- Identity details: gather the exact business name and client-confirmed legal recipient and address.
- Job parameters: record the work scope, city and state, project dates and document deadline.
- Client requirements: keep special insurance requests separate from basic recipient details.
- Request versus coverage: requesting a COI does not purchase insurance or resolve coverage gaps.
- Secure transmission: send supporting information and open questions through your agent’s usual secure channel.
- Review and retain: check returned details against the request, ask the agent about unresolved insurance questions, and retain the conversation. Do not edit an issued certificate yourself.
Example: a job with two open questions
Fictional scenario: a small contractor has a project description and deadline, but the client supplied only a trading name and asked to be “added to the insurance.” The useful next step is to obtain the recipient’s exact name and address and send the additional insured request to the agent separately. Do not replace that vague instruction with wording you assume will be accepted.
Review the response and retain the conversation
Compare the returned business and recipient information with your request. Record questions about dates or requested documents and send them back to the agent. Keep the request, response and issued documents together. If the job changes, describe the change and ask what needs updating; do not edit an issued certificate yourself.
Frequently asked questions
Who issues a contractor’s certificate of insurance?
Contact your insurance agent, broker or insurer through their established service channel. COI Desk organizes a request message; it does not issue certificates or purchase insurance for you.
What if the client asks to be an additional insured?
Keep that request separate from the recipient’s name and address. Send the original instructions to your agent and ask what the policy provides, which conditions apply and whether further action or documentation is needed.
Can I use this checklist as proof of insurance?
No. A checklist or generated request is a preparation aid. Obtain the actual insurance documents through the appropriate provider and ask your agent about the client’s requirements.
What if I do not have all the details?
Keep missing information marked as unknown and ask the client to confirm it. The builder can organize open questions alongside the details you already have. Review the generated message before sending it.
