What is a workers comp certificate of insurance?

A workers comp certificate of insurance is a dated summary issued by an insurer or authorized agent showing that a named business has a workers' compensation policy. It normally identifies the insured, carrier, policy number, effective and expiration dates, statutory workers' comp coverage, Employers' Liability limits, producer, and certificate holder. It summarizes coverage; it is not the insurance policy and cannot add terms that the policy does not contain.

How do I get a workers comp certificate of insurance?

Ask the insurer or authorized agent that issued your active workers' comp policy. Give them the certificate holder's exact legal name and mailing address, the contract or agency requirements, and any required endorsement wording. Review the completed certificate against the six checks on this page before sending it. If a state agency requires a controlled form, request that form rather than assuming a generic certificate will be accepted.

How can I verify a certificate of workers comp insurance?

Confirm the insured's legal identity, carrier, policy number, dates, workers' comp indication, Employers' Liability limits, holder, and required endorsements. Then verify active coverage through the insurer or the applicable state workers' compensation lookup. Use contact information found independently rather than relying only on the PDF, and recheck if the job continues past the expiration date.

Is an ACORD certificate accepted as workers comp proof?

Often it is used as a convenient certificate format, but acceptance depends on the requester and state rule. New York is a clear exception: for government permits, licenses, and contracts under WCL §57, the Workers' Compensation Board says an ACORD form is not acceptable and requires the applicable C-105.2, U-26.3, SI-12, SIG-105.2, or CE-200 proof.

Can a sole proprietor get a workers comp certificate?

Yes, if the sole proprietor has an active policy that the insurer can certify. A minimum-premium policy may be purchased to satisfy a contract even when the owner is excluded, but a certificate for an owner-excluded policy does not mean the owner's own injuries are covered. If the business claims an exemption instead, verify the state-issued exemption and its dates rather than treating it as insurance.

Does a certificate holder get cancellation notice automatically?

Do not assume so. Cancellation notice depends on the policy, endorsements, state law, and the certificate form. A certificate by itself cannot promise a right that the policy does not provide. Track the expiration date, request the applicable notice endorsement when the contract requires it, and verify active coverage independently.

Workers' Comp Certificate of Insurance: How to Get and Verify One

A workers comp certificate of insurance is a dated summary from an insurer or authorized agent showing that a named business has workers' compensation coverage. As of July 29, 2026, a useful certificate review has six checks: insured identity, carrier, statutory workers' comp, policy number and dates, Employers' Liability limits, and required holder or endorsement details.

What a workers' comp certificate proves

The certificate gives a client, general contractor, landlord, or agency a compact record of who is insured and when the policy is scheduled to be in force. It is the document businesses commonly exchange before a contract starts, especially when the hiring party wants to confirm that a subcontractor's employees are not being pushed onto the hiring party's workers' comp policy at audit.

It does not replace the policy or create coverage. Texas's insurance regulator states the practical rule directly: a certificate cannot alter, amend, or extend the coverage in the underlying policy. That is why an endorsement requirement — such as a waiver of subrogation — should be supported by the actual endorsement, not only wording typed into a certificate's description box.

Six fields to check before accepting a certificate

Read the workers' comp line separately from general liability, auto, and umbrella coverage. A checked general-liability row does not prove that statutory workers' compensation is active.

Six fields to verify on a workers' compensation certificate of insurance
Certificate field	What to verify	Why it matters
1. Exact insured identity	The legal name must match the entity on the contract. Confirm any DBA and the work location when the requester requires them.	A certificate for a related company, owner, or trade name may not prove that the contracting entity is insured.
2. Carrier and producer	Read the workers' comp row back to the named insurer, then confirm the issuing producer or agent using contact details you obtain independently.	The certificate is only a summary. The carrier or authorized agent is the source that can confirm what policy was issued.
3. Workers' comp Part One	The workers' compensation box should show statutory coverage for the state where the work is performed.	Part One pays benefits required by the applicable workers' comp law. It is not replaced by general liability, health, or accident insurance.
4. Policy number and dates	Confirm a real policy number and make sure the effective date is on or before work starts and the expiration date is after the period you need covered.	A certificate can be genuine but stale. Track renewal before expiration and re-verify coverage when a job crosses the policy date.
5. Employers' liability limits	Compare each accident, disease-policy-limit, and disease-each-employee amounts with the written contract requirement.	These dollar limits belong to Employers' Liability (Part Two), not the statutory workers' comp benefits shown in Part One.
6. Holder and endorsements	Check the certificate-holder name and address. If the contract requires a waiver of subrogation or another endorsement, obtain the actual endorsement too.	A certificate cannot create coverage or policy terms. Texas, for example, bars a certificate from altering or extending the underlying policy.

How to get a certificate

Start with the insurer or authorized agent that issued the active workers' comp policy.
Send the requester's exact legal name, address, contract requirements, and job dates.
Identify any required waiver, notice, or state-agency form. Ask for the endorsement when the contract requires policy wording.
Review the six fields above before forwarding the certificate, and keep the issued PDF with the contract file.

If you do not have a policy yet

An agent cannot certify coverage that has not been issued. Estimate the rate-driven portion from your state, class code, payroll, and experience mod, then compare actual carrier quotes. If you are self-employed, confirm whether the policy includes you or only exists to satisfy a contract.

State proof rules can override a generic certificate

“Send a COI” is not a nationwide legal standard. The required proof depends on the state, requester, business status, and type of transaction. These four primary-source examples show why the requester's instructions must be read before asking an agent for a generic form.

New York government permit, license, or contract

Proof: C-105.2 from a private carrier or licensed NY agent; U-26.3 from NYSIF; SI-12 for an individual self-insurer; CE-200 for an eligible exemption.

Check: The entity name and FEIN must match the applicant. The New York Workers' Compensation Board says an ACORD certificate is not acceptable proof under WCL §57.

California garment registration

Proof: A valid workers' comp certificate or the DIR certificate consenting to self-insurance.

Check: This sector-specific rule requires the complete legal entity, DBA, every garment-work location, and the prescribed certificate holder. A declarations page or insurance application is not accepted instead.

Texas employer coverage

Proof: Coverage may be through a licensed carrier, certified self-insurance, or a self-insured government entity; a private employer may also be a registered non-subscriber.

Check: Use the Texas DWC coverage-verification paths for the correct category. Do not assume a business calling itself “self-insured” is a certified self-insurer.

Florida contractor or subcontractor check

Proof: Carrier-filed proof of coverage or a valid Certificate of Election to Be Exempt, depending on the business and workers involved.

Check: Confirm the policy in Florida's Proof of Coverage database and check exemptions separately. Effective and expiration dates must cover the work being performed.

Compare the underlying state systems on the New York, California, Texas, and Florida rate guides.

How to verify active workers' comp coverage

Match the business. Compare the certificate's insured name with the contract, secretary-of-state record, DBA, and work location. In New York government work, the name and FEIN on the proof must match the applicant.
Check the dates. The effective date must precede the work. The expiration date must not pass unnoticed during the job, and an exemption must also be valid on the day the work is performed.
Confirm with the issuing source. Contact the carrier or agent through independently located contact details, particularly if the certificate was forwarded by the insured.
Use the correct state lookup. Texas separates carrier-insured, certified self-insured, government self-insured, and non-subscriber records. Florida keeps policy proof and owner exemptions in separate searches.
Save the evidence. Keep the certificate, verification result, endorsements, and renewal follow-up with the contract and audit records.

This checklist is general information, not legal or coverage advice. Contract wording and state rules control. Ask the insurer, licensed agent, requesting agency, or counsel about the requirement for your transaction.
