What a certificate of insurance is
A certificate of insurance is a one-page snapshot of your policy, issued by your insurer or agent. It is not the policy, and it changes nothing about the cover underneath it.
For a self-employed contractor it works like a door key. The permit counter, the commissary kitchen, the event office and the general contractor all want to see it before work starts. None of them reads the policy itself; they read the certificate.
The certificate is also the first thing you will buy after the policies, which is why it sits near the end of the get bonded and insured guide.

Who asks for one in Illinois
Three kinds of asker show up in this state, and each wants the same sheet with different words on it.
An agency asks, and is the strictest. The plumbing registration wants the Illinois Department of Public Health named as certificate holder on the certificate itself. An event asks: the Illinois State Fair requires vendors to file a certificate naming the Illinois Department of Agriculture as additional insured before doing any business on the fairgrounds. A private client asks, and usually wants a million-dollar per-occurrence limit plus their own name as additional insured.
The strictest asker sets your habits. Meet the agency's wording and a landlord's request is the easy version of the same task.

Get the insured name exactly right
The name on the certificate is the detail that gets certificates rejected. It must match the legal business name on the paperwork behind it, character for character.
Illinois is blunt about this. The plumbing registration states that the name on the certificate must exactly match the name of the business on the application. The State Fair says the same thing in its own words: the name of insured must be the same as the lessee on the contract, and certificates without the required wording are not acceptable.
If you registered a sole proprietorship under your own name and the certificate says "J. Doe Services," that is a rejection. If your LLC name has a comma or an LLC suffix the certificate drops, that is a rejection too. The page on how your structure changes the paperwork explains why the name on every document follows the entity you registered.

The limits the certificate has to show
The asker sets the limits, and in Illinois the published floors are specific enough to copy onto a checklist.
The plumbing registration lists four: $100,000 general liability per occurrence, $300,000 bodily injury, $50,000 property damage, and $500,000 workers' compensation for contractors with employees. The State Fair vendor certificate shows three: $300,000 per person, $500,000 per occurrence and $50,000 property damage. A landlord or a general contractor will commonly ask for more than either.
Carrying limits above the floor is fine. A certificate showing $1 million per occurrence satisfies a $500,000 asker. The reverse is not true, and the gap is discovered at the counter, not before.
| Who asks | General liability | Bodily injury | Property damage | Workers' comp |
|---|---|---|---|---|
| IDPH plumbing registration | $100,000 per occurrence | $300,000 | $50,000 | $500,000 if you have employees |
| Illinois State Fair vendors | $500,000 per occurrence | $300,000 per person | $50,000 | Only if employing help |
| Roofing license (RF-INS form) | $500,000 per occurrence | - | $250,000 | Proof of coverage required |
| Pesticide applicator license | Liability certificate with 30-day cancellation notice | $50,000 per person | $50,000 per occurrence | - |

The additional insured endorsement
"Make us additional insured" means the requester is added to your policy for claims arising out of your work for them. It is an endorsement to the policy, and the certificate is where they check it appears.
The State Fair's sheet is the cleanest public example of the wording an event office wants: the Illinois Department of Agriculture, its officers, agents, directors and employees, must appear as additional insured. Its one-line verdict is worth pinning above a desk — forms without this verbiage are not acceptable to participate.
An additional insured gets notice and defence from your policy; they do not get your limits raised. Confirm the endorsement actually issued, not just the certificate line, when a contract is worth more than the job fee. Where to buy the policy behind the certificate is covered on the insurance providers page.

No binders, no continuous certificates, and the 30-day rule
Illinois agencies refuse the shortcuts the insurance industry uses for speed. Know which ones before you rely on them.
The plumbing registration will not accept binders, and it will not accept continuous certificates. It also requires written notice to the Department at least 30 days before any cancellation, material alteration or expiration, and the certificate must be in force at all times for the registration to stay valid.
The practical shape of that: when a policy cancels, the certificate dies with it, and the agency is told before you are reminded. For a self-employed contractor the same rule that disciplines the agency paperwork protects the client relationship — a lapse shows up on someone's desk, not in your inbox. What a certificate does not cover at all is the bond side of the stack, and the bond versus insurance page draws that line.

Deliver it and keep it current
A certificate with a deadline attached is a calendar item, not an email attachment. Treat the deadline as part of the ask.
The State Fair fixes one in print: the certificate goes in with the contract, by July 1. The plumbing registration ties its certificate to the registration's own life — it must be valid for at least 60 days after the registration is issued and stay in force afterwards.
Set two reminders for every certificate you issue: one to renew the policy before it lapses, one to reissue the certificate to the holder who has it on file. The workers' comp line on the certificate has its own rules for the self-employed, and the workers' comp exemption page covers what goes on that line when you work alone.

Questions
Can I make the certificate myself?
No. The certificate is issued by the insurer or the agent. A self-made sheet with your own limits typed in satisfies nobody, because the whole point of the document is that a third party vouches for the cover behind it.
Does a certificate cost anything to issue?
The first one is normally free with the policy. Reissues are usually free too. What costs money is the additional insured endorsement on the policy itself, which some insurers charge for and some include.
What happens if my policy lapses after the certificate is on file?
The certificate stops describing anything. With the plumbing registration, the Department is owed 30 days' written notice before a cancellation or expiration, and failing to keep a current certificate on file suspends the registration until it is fixed.
Who sees the certificate if I never file it with a state agency?
Then it lives in the private chain: the client who asked, their property manager or landlord, and any permit office that wanted it before issuing. The document is the same in every case; only the holder's name changes.
