How to Spot a Fake or Invalid Contractor License

Fake contractor license claims are more common than most homeowners realize. A contractor might give you a made-up number, someone else's number, or a number for a license that expired or was revoked years ago. The good news: every state with a licensing requirement maintains a public database, and verifying a license takes less than five minutes. The bad news is that most homeowners never check.

What does a fake license claim actually look like?

Fake license claims take several forms, and some are more sophisticated than others. The simplest version is a contractor who makes up a number entirely, counting on the homeowner not to verify it. A more sophisticated version involves using a real license number — but one that belongs to a different contractor, a defunct company, or a license holder who no longer works for that business. Some contractors use their employer's license number on jobs where that license doesn't legally apply.

In California, the Contractors State License Board (CSLB) runs regular sting operations. In documented sweeps, a significant percentage of contacted contractors either could not produce a valid license, gave an incorrect number, or gave a license belonging to someone else. These are not edge cases. License fraud is common enough that California, Florida, Texas, and most other states have dedicated enforcement units targeting it.

• Made-up license number: Contractor invents a plausible-looking number with no record in the state database.
• Borrowed license number: Contractor uses a number belonging to a different business entity or individual.
• Expired license presented as current: Contractor gives a real number but doesn't mention the license expired.
• Revoked license: Contractor gives a number for a license that was revoked due to disciplinary action.
• Wrong trade classification: Contractor presents a license that doesn't cover the type of work being performed.

How do you verify that a contractor's license number is real and current?

Every state with a contractor licensing requirement maintains a public database you can search online. Start by asking the contractor for their license number directly — their response tells you something before you even look it up. A legitimate contractor provides it without hesitation and usually has it printed on their business card, truck, and paperwork. Hesitation, vague answers (“it's on file with the state”), or an inability to give you the number on the spot are all warning signs.

Once you have the number, go to your state's licensing board website and search by license number (not by name — name searches are less reliable because of spelling variations and business name changes). Confirm three things:

• The name on the license matches the contractor or company you're dealing with.
• The license status shows as “active” or “current” — not expired, suspended, or revoked.
• The license classification covers the type of work being performed (general contracting, roofing, electrical, plumbing, etc.).

CheckLicensed.comautomates this process across all 50 states. Instead of navigating each state's unique database interface, you enter the contractor's information and get a plain-English report that flags any status issues immediately.

What do “expired,” “revoked,” and “suspended” license statuses actually mean?

These three status designations are often confused, but they have meaningfully different implications for you as a homeowner:

Expiredmeans the contractor held a valid license at some point but did not renew it. An expired license is not a license. Working under an expired license is illegal in states that require one, and all the protections the license was supposed to provide — bond, insurance requirements, state oversight — have lapsed. Some expired licenses can be reactivated quickly; others cannot. If a contractor says their license “just expired” and they're “in the process of renewing,” do not hire them until the renewal is confirmed in the state database.

Suspended means the licensing board has temporarily prohibited the contractor from working, typically due to failure to maintain required insurance, failure to pay fines, or other administrative violations. A suspended license is not a valid license. The contractor cannot legally work during a suspension, and you have no state protections if something goes wrong.

Revokedis the most serious status. Revocation means the licensing board determined the contractor committed violations serious enough to permanently remove their license. Revocation typically follows documented consumer fraud, repeated complaints, egregious code violations, or criminal conduct. A revoked contractor who continues to work is committing a crime in most states. This status is a firm disqualification — there is no scenario where you should hire someone with a revoked license.

What does it mean when a contractor says they're “licensed through their employer”?

This is a common gray area that scammers exploit. In many states, a licensed contractor can legally employ unlicensed workers to perform work under the licensed contractor's supervision. The key word is supervision. If a company sends out crews who work unsupervised while the license holder is elsewhere, that's a violation of most states' licensing laws.

More importantly for homeowners: when a salesperson or crew leader tells you they're “covered by” or “licensed through” their employer, you need to verify the employer's license — not the individual's. Make sure the company you're signing a contract with (not a parent company, not a franchise, not a DBA) holds a valid license in your state for the work being performed. The contract should list the license number of the actual licensed entity.

This situation also arises with subcontractors. Your general contractor may be licensed, but the electrician or plumber they subcontract to may not be. Your written contract should require that all subcontractors are licensed for their respective trades.

What should you do if you've already hired someone whose license turns out to be fake?

If you discover mid-project or after the fact that your contractor's license is fake, expired, or doesn't match their name, take these steps immediately:

• Stop payment. Do not release any further payments until the situation is resolved. If you haven't paid final installments, hold them.
• Document everything. Save all contracts, texts, emails, receipts, and photos of the work. This is your evidence for any complaints or legal action.
• File a complaint with your state's licensing board. Even if the contractor isn't licensed, the board may be able to take action or refer to law enforcement. In California, file with the CSLB. In Florida, file with the DBPR. Most states have an online complaint form.
• File a police report. License fraud is a crime. A police report creates an official record and may be required for insurance claims or legal proceedings.
• File with your state attorney general. Most AGs have consumer protection divisions that handle contractor fraud complaints. Find yours at naag.org.
• Consult a construction attorney. For any project over $5,000, a one-hour consultation with a construction attorney is worth the cost. They can advise on your specific state's laws, your contract's enforceability, and your recovery options.

The easiest way to avoid all of this is to verify before you hire. CheckLicensed.comruns the database lookup for you, confirms the license matches the contractor you're dealing with, and flags status issues — so fake license numbers get caught before a dollar leaves your account.
