How to Verify a Contractor’s License and Insurance
Most homeowners take “licensed, bonded, and insured” at face value. The phrase means almost nothing until you check it, because each part is a separate credential with its own verification path, and a confident answer is not proof. This guide walks through the free checks first: how to confirm a license on your state board, how to read a certificate of insurance, and why you should call the carrier on that certificate rather than trust the paper. Then it covers the layer almost no one runs and the one that catches the worst operators: the lawful public-records research that reveals the real business entity behind the name, the dissolved companies a contractor left behind, and the liens, judgments, and complaint patterns that a clean-looking license will never show.
The Short Version
Verify each credential separately, and never on the contractor’s word alone. First, get the license number and look it up on your state contractor licensing board: the status must be active, not expired, suspended, or revoked, and the classification must cover your trade. Next, get a current certificate of insurance and confirm it names the contractor’s exact legal business name, lists both general liability and workers’ compensation, and is in effect for your project dates, then call the insurance carrier listed on the certificate to confirm the policy is active today, because a certificate is only a snapshot. Confirm the bond is active and adequate with the surety. Then do the part the credential checks miss: research the actual business entity behind the name through public records to surface prior dissolved companies, liens, judgments, and a pattern of complaints. People Locator Skip Tracing handles that last layer as lawful due diligence. It is not a consumer report, and it is not for any decision covered by the federal Fair Credit Reporting Act.

The free checks first, then the records research that catches the rest.
Watch Overview
“Licensed, Bonded, Insured” Is Three Separate Claims
Each one has a different issuer and a different way to confirm it.
The single most useful thing to understand before you hire is that “licensed, bonded, and insured” is not one credential. It is three, issued by three different bodies, each provable on its own and each meaning something different. A contractor who says all three may be telling the truth about all of them, some of them, or none, and the only way to know is to check each one at its source. Skipping straight to a handshake is how homeowners end up holding the bill for unpermitted work, an injured worker, or a job abandoned halfway through.
The license is issued by a state or local licensing board and shows the contractor met the jurisdiction’s requirements to do that trade. The bond is a surety bond that gives you a limited avenue of recovery if the contractor fails to perform or pay, and the surety company stands behind it. The insurance is the contractor’s own commercial coverage, normally general liability plus workers’ compensation, that protects you from being on the hook if property is damaged or a worker is hurt on your job. None of the three substitutes for the others, and a clean license tells you nothing about whether the insurance is active this week. The free checks below cover all three, and then the public-records layer covers what none of them can see: who you are actually dealing with.
Verify the License on the State Board
This is free, public, and takes a few minutes. Do it first.
Almost every state runs a contractor licensing board with a public lookup tool, and using it costs nothing. Ask the contractor for the license number directly, or find it on their estimate, truck, or website, then search the board by number or business name. You are checking four things. First, that the license exists and the status is active, not expired, suspended, revoked, or “inactive.” Second, that the name on the license matches the business you are about to contract with, not a similar-sounding company. Third, that the classification covers your trade: a general building license does not necessarily authorize electrical, plumbing, or roofing work, and an out-of-scope license is effectively no license for your job. Fourth, whether the record shows past disciplinary actions, citations, or complaints, which many boards publish right alongside the status.
If you are not sure which agency regulates contractors where you live, the federal government’s portal at USA.gov links to every state’s contractor licensing board and consumer-protection office, which is the fastest way to find the right lookup tool and where to file a complaint. One caution: a license number printed on a flyer is not the same as a verified license. Always confirm it on the board’s own site, because numbers get borrowed, mistyped, and invented.
Confirm the Insurance by Calling the Carrier
The certificate is a snapshot, not a guarantee. Verify it at the source.
Ask for a current certificate of insurance, the one-page summary, often called a COI, that an insurance agent issues to show a policy exists. A certificate is useful, but it has a built-in weakness that contractors and scammers both exploit: it only proves coverage existed on the day it was issued. It does not prove the policy is still in force, was not cancelled the next week, or was never forged in the first place. Treat the paper as a starting point, not the answer.
When you read the certificate, check the details closely. The named insured must match the contractor’s exact legal business name, not a personal name, a different LLC, or a trade name that does not appear on the contract. Confirm it lists general liability, which covers property damage the contractor causes, and workers’ compensation, which matters more than most homeowners realize: if a worker is injured on your property and the contractor carries no workers’ comp, the injured worker may be able to pursue you for medical bills and lost wages. Check the policy numbers and the effective and expiration dates, and make sure the coverage period spans your entire project, not a window that lapses mid-job. Be wary of a certificate that is blurry, undated, months old, or shows signs of having been altered.
Then do the one step almost everyone skips: call the carrier or agent listed on the certificate and confirm the policy is active right now, with the limits shown. Use the contact information from an independent source where you can, not only a phone number the contractor handed you, since a forged certificate can list a fake “agent” who simply confirms whatever you ask. A two-minute call to a real insurer is the difference between a document and actual coverage.
What Each Check Shows, and Misses
Four checks, four blind spots. Together they cover what one alone cannot.
| The Check | What It Confirms | What It Cannot Tell You |
|---|---|---|
| State License Board | The license exists, is active, the classification fits the trade, and any published discipline. | Nothing about the people or prior companies behind the license, or who the contractor was before this one. |
| Certificate of Insurance, verified with the carrier | That general liability and workers’ comp are real and active today, with limits and dates that cover the job. | Whether the named insured is the entity actually doing your work, or coverage that lapses after the certificate date. |
| Surety Bond | A limited, defined avenue of recovery if the contractor fails to perform or pay, confirmed with the surety. | The bond amount is often modest and may not come close to a large project loss. |
| Public-Records Research Due Diligence | The real business entity behind the name, prior dissolved companies, liens, judgments, lawsuits, and complaint patterns. | It is not a consumer report and is not used for any decision the Fair Credit Reporting Act covers. |
Read across that bottom row and the gap becomes obvious. The state board, the certificate, and the bond all describe a credential. None of them tells you whether the confident person on your doorstep is the same operator who dissolved two complaint-ridden companies last year and reopened under a fresh name. That is a question about people and entities, and it is answered with public records, not credential lookups.
Don’t Skip the Bond
It is a real, if limited, layer of protection. Confirm it with the surety.
The bond is the credential homeowners understand the least. A contractor’s surety bond is not insurance for you and it is not a savings account; it is a financial guarantee backed by a surety company that gives you a defined way to make a claim if the contractor breaks the rules, abandons the job, or fails to pay subcontractors or suppliers. In many states the bond information appears on the same licensing-board record as the license, so you can often see the bond number, the surety, and the amount in the same lookup. Where it is not shown, ask for the bond number and call the surety to confirm it is active.
Set your expectations honestly. Bond amounts are frequently modest relative to the cost of a major renovation, so a bond should be treated as a backstop, not a guarantee you will be made whole. Its real value is twofold: it gives you an avenue of recourse the bond was designed for, and the fact that a surety was willing to write the bond at all is one more independent party that vetted the contractor. A contractor who cannot or will not produce a bond number that checks out is telling you something worth hearing.
The Check Almost No One Runs: The Entity Behind the Name
A clean license can sit on top of a long history of dissolved companies.
Here is the limitation that lets bad contractors keep working: credentials attach to a business entity, but reputations and complaints attach to people, and the two come apart easily. The friendly truck and the brand on the estimate are a trade name. Behind it is usually a limited liability company or corporation, and that legal entity, not the slogan, is what holds the license and the insurance, and what you actually sign a contract with. Confirming that the entity on the certificate, the license, and the contract are all the same company is basic protection, and a mismatch, where the insurance names one LLC and the contract names another, is a red flag that the coverage you verified may not apply to your job.
The deeper question is what that entity’s history looks like, and that is exactly what public records can answer. A search of the secretary of state’s business registry shows when the LLC was formed, who its registered agent and listed principals are, and whether it is in good standing or dissolved. Court and county records show liens, judgments, and lawsuits against the entity or its principals. Read together, these records tell you whether you are dealing with an established business or a shell formed last month, and whether the people behind it are the subject of a stack of legal disputes. This is ordinary due diligence, the same approach you would take when you want to find out who actually owns a business or to investigate a business before suing. It is general background research for a lawful purpose, not a consumer report, and our investigators run it the same careful, records-based way every time.
The Phoenix-Company Pattern
The maneuver that lets a bad contractor outrun every complaint.
The most damaging contractors are rarely unlicensed amateurs. They are operators who understand exactly how the system works and use its seams. The classic move is the phoenix company: a contractor racks up complaints, disputes, or judgments under one business name, quietly dissolves that entity, and rises again under a brand-new LLC with a clean slate. The license history does not follow the person, the old reviews are buried, and a homeowner checking only the new entity’s credentials sees nothing wrong, because on paper, nothing is. The credential checks are working as designed; they simply were never built to track a person across a string of companies.
Public records are how you see the pattern the credential lookups hide. When the same individual appears as the principal or registered agent of several construction LLCs formed and dissolved in quick succession, often at the same address or phone number, that sequence is visible in business-registry and court records even when each individual company looks fine. Surfacing that history is squarely the kind of work behind our contractor scam investigation and broader home-improvement fraud investigation services. It is the same lawful, public-records discipline that powers a thorough business background check before you commit, applied to the person standing behind the trade name rather than the name itself.
Red Flags to Walk Away From
One of these is a caution. Several together is your answer.
No License Number
They cannot or will not give you a license number to verify, or the number does not check out on the state board.
“My Insurance Just Lapsed”
The coverage is “renewing,” the certificate is “in the mail,” or the cert they show is months old or undated. Active or it does not count.
Cash Only, Large Upfront
They want a big deposit, cash, before any work begins, and resist a written contract with a payment schedule tied to milestones.
Door-to-Door, “Sign Today”
Uninvited after a storm, claiming urgent damage, with a price that “disappears” if you do not commit on the spot. Pressure is the tell.
A Brand-New LLC, No History
The business was formed weeks ago with no track record, especially when the principal is tied to other recently dissolved companies.
Names That Do Not Match
The license, the certificate of insurance, and the contract each show a different business name. The coverage may not apply to your job.
The Verification Sequence
Run these in order before any money changes hands.
Get the License Number
Ask directly and write down the exact legal business name. Note the trade or classification you need the work to fall under.
Verify on the State Board
Look up the number on your state licensing board. Confirm active status, a matching name, the right classification, and check for published discipline.
Read the COI, Call the Carrier
Confirm general liability and workers’ comp, matching named insured, and current dates. Then call the insurer to confirm the policy is active today.
Confirm the Bond and the Entity
Verify the bond with the surety. Then research the business entity in public records for prior dissolved companies, liens, judgments, and complaints.
Then Hire, in Writing
Only once all of it checks out, sign a written contract with a clear scope and a payment schedule tied to milestones, never a large cash deposit.
Who Runs This Check
The credential plus public-records combination protects more than homeowners.
Homeowners
Vet a contractor before a major project
Property Managers
Screen vendors across many doors
General Contractors
Verify a subcontractor’s COI and entity
Insurers

Diligence on prior work and the builder
Anyone Hiring
Know the entity behind the name
If you would rather not assemble the records yourself, our investigators run the entity-and-history layer as lawful, permissible-purpose due diligence: confirming the real company behind the trade name, surfacing prior dissolved entities, and pulling the liens, judgments, and complaint patterns the credential checks never show. This work draws on the same public-records sources behind a full asset and lien search and our broader skip tracing, and it pairs naturally with understanding the different types of background checks available for a hiring decision. It is general due diligence and background information, not a consumer report. We are not a consumer reporting agency, and our research is not used for any decision governed by the Fair Credit Reporting Act. For a legitimate matter, an initial entity locate typically comes back within 24 hours.
Our Commitment
We do not sell a “contractor is safe” stamp or grade anyone’s character. We do the lawful, public-records research the credential checks miss: the real entity behind the name, the dissolved companies, the liens and judgments, and the patterns. You get the facts to make your own decision. Honest, permissible-purpose skip tracing since 2004.
Frequently Asked Questions
How do I verify a contractor’s license for free?
Get the license number, then look it up on your state contractor licensing board’s public lookup tool, which is free. Confirm the status is active, the name matches the business you are hiring, the classification covers your trade, and check for any published disciplinary actions. If you are unsure which agency regulates contractors in your state, USA.gov links to every state board and consumer-protection office.
Is a certificate of insurance proof that a contractor is insured?
Only partly. A certificate of insurance proves coverage existed on the day it was issued, not that the policy is still active. It can be outdated, cancelled, or forged. Always call the insurance carrier or agent listed on the certificate to confirm the policy is active today, with the limits shown, and that the named insured matches the contractor’s exact legal business name.
What insurance should a contractor have?
At minimum, general liability, which covers property damage the contractor causes during the work, and workers’ compensation, which is critical: if a worker is injured on your property and the contractor has no workers’ comp, the injured worker may be able to pursue you for medical bills and lost wages. Confirm both appear on the certificate and that the coverage dates span your entire project.
What is the difference between licensed, bonded, and insured?
They are three separate credentials. The license is issued by a licensing board and shows the contractor is authorized for the trade. The bond is a surety guarantee that gives you a limited avenue of recovery if the contractor fails to perform or pay. The insurance is the contractor’s own coverage protecting you from liability for damage or injury. Each must be verified separately at its own source.
Why check the business entity if the license is clean?
Because a clean license can sit on top of a troubled history. Credentials attach to a specific business entity, but complaints and judgments follow the people behind it. A search of the secretary of state’s registry and court records reveals the real company, prior dissolved entities, liens, judgments, and lawsuits the license record never shows. That history is the strongest predictor of how a job will actually go.
What is a phoenix contractor?
A phoenix contractor is an operator who accumulates complaints, disputes, or judgments under one business name, dissolves that company, and reopens under a brand-new LLC with a clean slate. The license history does not follow the person, so checking only the new entity shows nothing wrong. Public business-registry and court records can reveal the same individual behind several recently formed and dissolved construction companies.
Is this research a background check or a consumer report?
No. This is general public-records due diligence for a lawful, permissible purpose. People Locator Skip Tracing is not a consumer reporting agency, and our research is not a consumer report and is not used for any decision governed by the federal Fair Credit Reporting Act, such as employment or tenant screening. It is background information to help you make your own hiring decision, and it is not legal advice.
What does People Locator Skip Tracing do that I cannot do myself?
You can and should run the free license, insurance, and bond checks yourself. Our investigators add the public-records layer that is more time-consuming to assemble: confirming the real entity behind the trade name, tracing prior dissolved companies tied to the same principals, and pulling liens, judgments, and complaint patterns into one picture. We deliver the facts; the hiring decision stays yours.
