How to spot a fake or altered certificate of insurance

Why fake certificates happen

A certificate of insurance is a one- or two-page form, often a PDF. Anyone with a PDF editor can change a date, raise a limit or paste in a new name. Most bad certificates are not elaborate forgeries. They are last year's certificate with the dates changed, a limit typed over, or another company's certificate with a new name.

The people who do it are usually under pressure: a subcontractor whose policy lapsed for non-payment, who can't get a limit it needs, or who wants to start Monday. That is why the risk is highest when a job is starting fast.

Warning signs on the page

None of these proves fraud on its own. Each one is a reason to verify before work starts. Insurers who fight certificate fraud point to the same signs (MEM):

Mixed fonts or sizes in the fields that matter: the insured's name, policy numbers, dates, limits or the certificate holder.
Text that sits off the lines, crooked boxes, blurred areas or a page that looks like a photocopy of a photocopy.
An insurer name that is slightly off: a missing word, a misspelling, a company you can't find.
Policy numbers in the wrong format for that insurer, or the same number on two different coverages.
Dates that don't add up: a policy term that isn't one year, an effective date after the certificate date, or a certificate dated before the policy began.
A producer you can't reach: no phone number, a free email address, or contact details that lead nowhere.
Limits that are suspiciously round and high for a small subcontractor, or exactly what you asked for when everything else on the page is generic.

Checks that confirm coverage

Verification goes to the source, never to the person who sent the certificate.

Call the producer listed on the certificate. Find the agency's phone number yourself, from its website or a directory, not from the certificate. Ask them to confirm the insured, policy numbers, dates and limits, and to send the certificate directly to you.
Confirm the insurer exists and is licensed. The NAIC's Consumer Insurance Search lets you look up an insurer and its license status by state.
Confirm the agent is licensed. Your state insurance department has a license lookup for agents and agencies.
For workers' compensation, check the state record. Many states publish coverage lookups that show whether an employer has an active workers' comp policy. Search your state's workers' compensation agency.
Ask for certificates to come from the broker. A certificate emailed by the agency, from its own domain, is much harder to fake than a PDF forwarded by the subcontractor.

Why this matters more than it seems

An uninsured subcontractor doesn't just leave you without the coverage you asked for. In most states a general contractor can be responsible for workers' compensation benefits to an injured employee of an uninsured subcontractor. One industry review counted 44 states and the District of Columbia where the general contractor becomes the "statutory employer" in that case, and the premium for those workers can be charged to the general contractor at audit even if no one is hurt (Insurance Journal).

Make it hard to fake in the first place

Ask for certificates before work starts, not on the first day of the job.
Accept certificates only from the broker, or confirm every one with the broker.
Keep the history. A certificate that changes from one year to the next in ways that don't make sense is a signal.
Track renewals. Many fakes appear at renewal, when a policy has quietly lapsed.

Where Certgio fits

Certgio reads each certificate and compares it with your contract requirements. It checks the insured's name, the coverages, the limits and the dates, and flags what doesn't match. It also keeps each vendor's certificate history and reminds you before policies expire, so a certificate that changes oddly or lapses gets noticed.

Certgio reads the document it is given. It can't confirm with an insurer that a policy exists. For a certificate that looks wrong, call the agency.
