How to Read a Certificate of Insurance

A reading order

A certificate of insurance is a summary an insurance producer (an agent or broker) prepares for someone other than the policyholder. Read it in this order so you do not stop at the first limit that looks familiar.

Who is named as the insured.
Who is named as the certificate holder.
Which coverage lines are present, and which insurer each line points to.
The effective date and the expiration date on each line, not one date for the whole page.
The limits as printed, label by label, compared later to your contract. The comparison is a second step. The reading step is “write down the labels and the figures.”
The description of operations and any remark about additional insured status or waiver of subrogation.
The producer’s name and phone, which is who you call to correct a typo. That call is not confirmation from the insurer unless your standard says you also need the insurer or the broker of record to confirm.

If a field is illegible, leave your note blank and ask for another copy. A guessed digit is worse than a blank. The tracking consequence of blanks is covered in the spreadsheet formulas: a blank required date has to stay visible.

ACORD forms, at a high level

In the United States, many liability certificates are issued on ACORD 25, the certificate of liability insurance. ACORD publishes the form. Editions differ, so do not memorize a sentence from one edition and assume the PDF in your hand says the same thing. Read the sentence that is printed.

ACORD 28 is a different form, used as evidence of commercial property insurance. An ACORD 28 does not stand in for a liability certificate unless your contract asked for property evidence. Some certificates are not on an ACORD form at all. They may be on a producer’s or an insurer’s letterhead. Read the same fields if they are there, and do not treat a missing field as “probably fine.” Missing is unknown.

This site will not reproduce the forms. They are ACORD’s documents. The field names below are the ones coordinators use. If a certificate uses different labels, record the label that is printed rather than forcing it into a box.

The fields that matter

Field	What you are looking at	What to record	What it does not settle
Producer	The agency or brokerage that issued the certificate. Usually at the top, with an address and phone.	The name and a phone or email you can actually use.	That the insurer reviewed your contract, or that this agency is still the broker of record. Unknown unless you confirm it.
Named insured	The person or company the policies are said to cover. On ACORD 25 this is the insured block.	The legal name exactly as printed.	That this entity is the one that signed your contract. A parent, an affiliate, or a trade name is a mismatch until someone checks.
Insurer and insurer letter	A list of insurance companies, often lettered, and a letter on each coverage line that points back at that list. A NAIC number is sometimes printed next to the company. It is an identifier, not a grade.	The company name for each line you care about. Copy the letter if you need to show which row you mean.	That the company is admitted in your state, is solvent, or will pay. This page does not check NAIC numbers. A number you cannot read is unknown, not a reason to type a different one.
Policy number	The identifier printed on that coverage line.	The characters as printed, including letters.	Nothing about whether the policy is in force today. This page intentionally does not show an example number.
Coverage type	The line: commercial general liability, automobile, umbrella or excess, workers’ compensation, and sometimes other lines in a blank row.	Which of those rows have information, and which your contract required and left empty.	That an empty row means the coverage is forbidden, or that a filled row means your contract asked for it.
Effective date and expiration date	The start and end printed on that line. Lines often differ.	Both dates, per line.	That the policy was not cancelled after the certificate was issued. The date is what the producer stated, as of that certificate.
Limits	The figures and labels for that line. General liability often has several: each occurrence, damage to rented premises, medical expense, personal and advertising injury, general aggregate, and products-completed operations aggregate. Automobile may show a combined single limit or split limits. Umbrella or excess usually shows each occurrence and aggregate. Workers’ compensation rows often say statutory, or show employers’ liability figures. Your certificate may label these differently.	The label and the figure, as printed. Do not collapse a liability line into one number.	Whether the figure meets your contract. Whether an aggregate still remains after other claims. A certificate usually shows the limit written on the policy, not what is left. Remaining limits are unknown from the certificate alone.
Description of operations, locations, or vehicles	Free text. It may name a project, a building, or a vehicle, and it may include remarks about additional insured status or waivers.	The project or location named, and any remark you are relying on, quoted shortly in your notes.	That the text changes the policy. It is a description. See the next section.
Certificate holder	The party the certificate was addressed to, often in a box at the bottom, with an address.	The name and address as printed.	Additional insured status. Being the holder means you were sent the summary. It does not, by itself, make you an insured.
Certificate number or revision	An identifier for this piece of paper, which is not the policy number. Some certificates also show a revision.	The number and revision if they are printed, so you can tell two versions apart.	Which version is “the” certificate if you threw the earlier PDF away. Keep both.
Authorized representative	A signature, and sometimes a date, from the producer.	That someone signed, and the date if there is one.	That the signature makes the holder an additional insured, or that the insurer saw the document. A signed certificate can still be wrong.

Remarks, additional insured, and waiver

Additional insured status, when a policy provides it, is granted by the policy or an endorsement. A waiver of subrogation, when a policy provides it, is also a policy term. Certificates often mention both in the description box. Treat the sentence as a clue about what the producer thinks was issued.

If your contract requires the endorsement itself, the sentence is not the last step. Ask for the form and file it with the certificate. If your broker or counsel has told you that, for this contract, the certificate wording is enough, write that standard down so the next reviewer does not invent a stricter or looser one. This page will not choose for you.

Primary and noncontributory wording is the same kind of item: a contract request, sometimes a remark, confirmed in the forms if that is your standard.

Cancellation text needs the same care. Many certificate editions say something about the insurer endeavoring to notify the holder if a policy is cancelled, and they also say the certificate itself does not change the policy or give the holder extra rights. The exact sentence depends on the edition. Read the one on the page. An “endeavor to” sentence is not the same thing as an endorsement that requires notice to you. Whether you have a notice right is unknown from a paraphrase. It is a policy and contract question.

What a COI shows

On the date it was issued, the producer represented that the named insured had the policies, dates, and limits printed on the form, and addressed that representation to the certificate holder. That is useful. It is the evidence you can file, search, and hand to an auditor as “what we were shown.” Your review notes — reviewer, date, and the requirement set you used — are what show that a person looked. The certificate alone does not show that the look happened.

What a COI does not prove

It does not prove the policy is in force today. Policies cancel, non-renew, and get replaced. A process that only reads the PDF on the day it arrives will miss a later cancellation. Whether you will be told is unknown until you read the notice wording and any endorsement that actually requires notice.
It does not prove a claim will be paid. Exclusions, conditions, and the facts of the loss live in the policy and the claim.
It does not prove you are an additional insured, that a waiver of subrogation exists, or that primary and noncontributory wording applies. The remark is not the endorsement.
It does not prove the limits are still available. Aggregates can be reduced by other claims. The certificate is a poor source for what remains.
It does not prove the description matches your job unless you compare the words to the project or the building.
It does not prove the named insured is the company you contracted with unless you compare the names.
It does not prove the producer is authorized by that insurer for this policy. If your standard requires confirmation beyond the certificate, the certificate is the start of that request.
It does not set your requirements. A limit printed on someone else’s certificate is not a recommendation for your contract. This page states no target figures for that reason.

What to write down

After the reading, the tracking record should be able to show the named insured, the holder, each required line’s insurer, policy number, effective date, expiration date, and limits as printed, plus whether an endorsement is on file, missing, not required, or unknown. The spreadsheet columns are built for that. Status is a separate decision: received, exception, or accepted, with the reviewer’s name.

Then follow the request and renewal habit that matches the relationship. Vendor certificates and subcontractor certificates are the same document with different exhibits and different consequences for a gap. COI tracking is the cycle that makes the next reading happen before the dates you just wrote down have passed.

Unknowns

Whether any particular certificate’s additional insured wording matches your contract. Compare them. If you cannot tell, it is unknown.
Which ACORD edition you will receive next. Read the form in front of you.
Whether a signature is ink, electronic, or applied by a certificate system, and whether that method matters under your standard. This page does not rank signature methods.
What “statutory” workers’ compensation benefits are in a given state. Record that the row says statutory, and ask your broker if your exhibit requires something more specific.
Remaining aggregates, current in-force status, and whether the producer is still appointed for that policy.
