Anyone can print a business card that says "licensed electrician." The only way to know if it's true is to check it yourself, the same way you'd check a used car's title before buying. It takes about five minutes, costs nothing, and it's the single best filter for keeping unqualified or uninsured workers out of your electrical panel.
Why does this actually matter?
Electrical work is one of the few home projects where a mistake isn't just expensive — it can burn your house down or electrocute someone. That's why every state requires a license to do it, and licensing boards exist specifically to track who's qualified, who's had complaints filed against them, and whose license has been suspended or revoked. Skipping the check doesn't just risk bad work; it means you have no recourse — no bond to file a claim against, no insurer to cover damage, no licensing board to complain to — if something goes wrong.
The FTC's guidance on avoiding home improvement scams puts it plainly: consider only contractors who are licensed and insured, and verify both directly with your state or county rather than taking a business card at face value.
How do you look up an electrician's license by state?
Every state (and many cities) maintains its own licensing board, and most publish a no-cost online lookup. The process is nearly identical everywhere:
- Search "[your state] electrical contractor license lookup" or go straight to your state's licensing board site.
- Enter the license number from the electrician's estimate, business card, or truck signage — or search by business name if you don't have a number yet.
- Confirm the status reads active, not expired, suspended, or revoked.
- Check the license classification matches the work you need (residential wiring, low-voltage, etc. — some states split these into separate licenses).
- Look for a complaint or disciplinary history, if the board publishes one.
California's CSLB "Check a License" tool is a good example of what these lookups typically show: license status, classification, bond information, and workers' comp coverage, all in one record. If you're not sure which agency covers your state, the NASCLA consumer directory links out to every state's licensing board in one place.
| What you're checking | Where to find it | Why it matters |
|---|---|---|
| License status | State licensing board lookup | Confirms it's active, not lapsed or disciplined |
| Classification | Same lookup, listed with the license | Confirms they're licensed for electrical work specifically |
| General liability insurance | Certificate of insurance (COI) from the electrician | Covers damage to your home from their work |
| Workers' comp | COI, or the state lookup if it's listed | Protects you if a worker is injured on your property |
| Bond (where required) | State lookup or licensing board | Gives you a claim path if work is defective or abandoned |
What should you ask for as proof of insurance?
A license lookup usually won't show you full insurance detail, so ask the electrician directly for a certificate of insurance (COI). A real COI lists:
- The insurance company's name and the policy number
- Policy expiration dates (check these — an expired COI is as good as none)
- General liability coverage limits
- Workers' compensation coverage, if they have employees
Don't stop at reading the paper. Call the insurance agent or company listed on the COI and ask them to confirm the policy is active and the electrician is the named insured. This takes one phone call and rules out the (not uncommon) practice of showing an old certificate from a policy that's since lapsed or been canceled.
What are the red flags of a fake or borrowed license?
A few signs suggest you should slow down before signing anything:
- The license comes back expired, suspended, or under a different name than the person or company in front of you.
- They're reluctant to give you a license number at all, or say it's "in the mail" or "under review."
- The COI's description of operations doesn't mention electrical work — some contractors carry cheap general handyman coverage that excludes it entirely.
- They pressure you to skip permits or say the inspection "isn't necessary" for the job. Licensed electricians pull permits for anything beyond minor repairs, because it's the law and it protects you at resale.
For more on where that line falls, see Can a Handyman Legally Do Electrical Work? — a lot of unlicensed work gets done under the "handyman" label specifically because it's harder to trace.
Why do good electricians volunteer this information?
A licensed, insured electrician has nothing to hide and every reason to make verification easy — it's proof they're competing on skill, not on cutting corners. You'll usually see the license number printed right on their trucks, estimates, and business cards, and they'll hand you a COI before you ask twice. Hesitation, vague answers, or a "my boss handles that" response is itself useful information.
This is also where getting more than one estimate pays off. When you compare quotes from a few licensed, insured electricians side by side, you're not just comparing price — you're seeing whether the scope, materials, and timeline are consistent across people who all had to earn the same credential to bid. A single quote leaves you hoping the number is fair; a few licensed quotes let you actually know.
What to do about it
Before you sign anything or hand over a deposit:
- Get the license number in writing on the estimate.
- Look it up on your state's licensing board site and confirm active status and the right classification.
- Ask for a current COI and call the insurer to confirm it's active.
- Watch for red flags — expired paperwork, reluctance to share a license number, or pressure to skip permits.
- If anything doesn't check out, especially warning signs like the ones covered in What Are the Warning Signs of Unsafe Wiring in Your Home?, get a second opinion before work starts, not after.
