License Plate Lookup: Free, Legal Options by State

By Mohamed SkhiriUpdated November 8, 2026Checked against 18 U.S.C. 2721–2725 and each state agency's forms

Every license plate leads back to a registration record at a state motor vehicle agency, and that record holds the owner's name and address. So it's natural to assume a plate search should be easy. It isn't, and that's deliberate. Since the late 1990s, federal law has kept those records private unless the person asking has a reason the law recognizes. We built this guide so you can find the legal route quickly instead of paying a website for something it can't honestly deliver. Think of it as a license plate lookup, free to use, that tells you the truth about what's possible.

The law behind every license plate lookup

The Driver's Privacy Protection Act (DPPA), 18 U.S.C. 2721–2725, says a state department of motor vehicles may not knowingly disclose personal information from a motor vehicle record except for the uses listed in the law. Personal information includes the owner's name, address and phone number. That's why a check of a license plate owner isn't something any member of the public can do with a quick search.

The law has teeth on both sides. A person who knowingly obtains, discloses or uses personal information from a motor vehicle record for a purpose the law doesn't permit can be sued by the owner. Under 18 U.S.C. 2724, the court can award actual damages of not less than $2,500, punitive damages for willful or reckless violations, and attorneys' fees. Several states add their own penalties: New Jersey makes knowingly obtaining or disclosing record information for a non-permitted use a fourth-degree crime, and Texas treats falsifying a record request as a third-degree felony.

What a free license plate lookup can and can't show

Strip away the owner's personal information and a plate record still holds vehicle details, which some agencies treat differently. Texas, for example, says it may provide non-personal information such as the year, make, model, weight, and title number and status. Georgia offers a VIN-based printout with no owner names. Ohio's registration record shows current registration only, not history.

That's the reality behind every license plate lookup free offer: a lawful, low-cost lookup can usually tell you about the vehicle, not the person. If you're searching for a free lookup of a license plate owner, the honest answer is that no state gives that out for curiosity, and our guide says so when you choose that reason. A reverse license plate lookup of the owner is possible only through a permitted use, which is what the tool above sorts out.

The permitted uses, in plain English

The DPPA lists the purposes for which personal information may be released. Summarized from 18 U.S.C. 2721(b):

1. Government agencies, including courts and police, carrying out their functions.
2. Vehicle and driver safety and theft, emissions, recalls and similar manufacturer matters.
3. Legitimate businesses verifying information an individual gave them, and correcting it to prevent fraud or recover a debt.
4. Court and agency proceedings, including serving legal papers and enforcing judgments.
5. Research and statistics, as long as nobody is contacted or identified.
6. Insurers, for claims, anti-fraud work, rating and underwriting.
7. Notices to owners of towed or impounded vehicles.
8. Licensed private investigators and security services, for one of the other permitted purposes.
9. Employers verifying a commercial driver's license.
10. Private toll facilities.
11. With the person's consent, in the ways the law describes.

Notice what's missing: finding out who owns a car that cut you off, or checking up on a neighbor. For those, the route is the police if there's a real problem, and nothing at all if there isn't.

The right route for common situations

• Crash or hit-and-run: report it to the police with the plate number, then give the plate and report number to your insurer. Both are allowed to identify the owner.
• Car abandoned on your property: call your local police non-emergency line or a licensed towing company. Towing notices are a permitted use.
• Buying a used car: you don't need the owner's name. Check the seller's ID against the title, check the VIN for recalls, and order a title history from an approved NMVTIS provider.
• Your own vehicle: you can always request your own record with your state's form.

Every name for the same search

People phrase this search a dozen ways, and the answer depends on what's behind the words, not the words themselves:

• "License plate lookup free" or "lookup plate number": a free lookup can tell you about the vehicle in some states, but not about the owner.
• Reverse lookups: a reverse license plate lookup asks for the owner's identity, which requires a permitted use. A licence plate number reverse lookup, with the British spelling, runs into exactly the same rules.
• "Look up people by license plate": the DPPA exists precisely to stop this for anyone without a permitted use.
• "Bumper license plate lookup" or "check number plate": usually someone who saw a plate on a bumper and wants to know whose it is. Unless there's a crash, a crime or a towing situation, the agency won't say.
• Every other state: the same federal rules apply everywhere, whatever the spelling or wording of the search; only the form and fee change. Pick the state in the tool to see them.

Put simply, a license plate lookup free of charge and free of rules doesn't exist through official channels. A lawful one costs a few dollars and needs a reason.

Vehicle record request forms and fees by state

If you do qualify, each state has its own request form and fee. This table summarizes them; choose your state in the tool above for the full details and the official link.

A few state-specific points people search for often:

• Maryland (MD): an MD tag number lookup, sometimes searched as an MD licence plate lookup, uses form DR-057 or the MVA's public records web form. The MVA says records are private unless requested by you, the police, an insurer or another approved official purpose, so an MD license plate lookup for free, for any reason, isn't available. Our Maryland tag lookup guide walks through the form.
• Connecticut (CT): there's no free CT license plate owner lookup; the DMV's J-23 copy records request costs $20, and another person's record is released only for purposes in section 14-10 of the state statutes.
• Massachusetts (MA): an MA license plate lookup of the owner (or an MA licence plate lookup, as many visitors spell it) goes through the RMV's Request for Personal Information, at $5 per record.
• New Mexico (NM): NM license plate lookup access for businesses runs through MVD's subscription system; individuals use the confidential records release form, explained in our New Mexico license plate lookup guide.
• Tennessee (TN): the Department of Revenue's Vehicle Information Request costs $1 per printout, but owner details still depend on a permitted use, so a TN license plate lookup for free isn't how it works.
• Alabama (AL): an AL license plate lookup goes through the Department of Revenue's Records Request Portal, open only to authorized requesters with a permitted use; our Alabama tag number lookup guide covers rule 810-5-1-.485.
• Florida (FL) and Montana (MT): Florida prices records one by one on form HSMV 90510, while Montana's MVD runs a paid online vehicle search under its own privacy act. See the Florida plate lookup and Montana license plate lookup guides.
• Louisiana (LA) and Arkansas (AR): Louisiana's OMV sells title histories on form DPSMV1958, and Arkansas ties owner details to the DPPA's permitted uses; see the Louisiana plate lookup and Arkansas license plate lookup guides. An AR license plate lookup or AR license plate search for owner details runs through the DFA under those DPPA rules.
• West Virginia (WV): we didn't find a published individual request form for a WV license plate search; ask the DMV directly.

Detailed guides are available for a Texas license plate lookup, a Michigan license plate lookup, an Illinois license plate lookup, an Arizona license plate lookup, a Minnesota plate number search, a Wisconsin plate lookup, a Washington plate number search, an Indiana license plate lookup and a New Jersey license plate number search.

How to run a license plate, and who can

"Running" a plate means checking it against the state's registration records, the way an officer does at a traffic stop. Police do it through law enforcement databases, and that's the only kind of plate check that returns an owner's name and address on the spot. Everyone else who needs to run a license plate goes through the state agency's request form, states a purpose the DPPA permits, and waits for the answer by mail or email. An officer will run the license plate in seconds; a website that says it will run license plates for anyone is selling something else, and no one will run a plate's owner details for you legally without a permitted reason. Looking up a license plate number yourself follows the same rules. Here's how to run license plates the lawful way:

1. Check that your reason is allowed. An insurance claim, a court case, a towing or impound notice, or verifying a vehicle you're buying all qualify in most states; curiosity doesn't.
2. Use your state's form. The table below lists it, with the fee. Some states also accept requests from licensed private investigators acting for a permitted purpose.
3. Send identification and payment. Agencies record who asked and why, which keeps running a license plate number from becoming a way to track people.

A license tag number search is the same request under another name, and so is asking how to run a tag; "tag" is what many Southern states call the plate. And if a friend offers to have someone run this license plate for you through a work database, don't: misusing a law enforcement or DMV system is a crime for the person who does it, and the DPPA lets the owner sue anyone who obtains the information for a purpose the law doesn't allow.

Can you look up a VIN by plate?

A VIN look up by plate number works the same way as an owner lookup: the VIN behind a plate is part of the registration record, so it comes through the state's request form, not a free public search. Many insurers and dealers can see it through their own systems. If you're buying the car, simply ask the seller for the VIN and check it against the dashboard, then run it through our free VIN decoder.

Can you find someone's address from their license plate?

Can you find someone's address with their license plate, or by their license plate number alone? Not as a member of the public, and not for free. You can't look up someone's address from their license plate on a website, and you can't lookup an address from a license plate at the DMV counter without a permitted use. The DPPA treats an address as personal information, alongside a name, photo and driver's license number, so a state can't release it to a stranger who only has the plate number. That's true whatever the plate is called where you live: you can't find an address from a number plate in the UK sense, find an address from a registration plate, or find an address with a license plate number in the U.S. without one of the law's permitted reasons. When you have a real reason, such as a crash or damage to your property, the address reaches you another way: police take the report and exchange the drivers' details, your insurer requests the record, or a court orders it. Sites that claim to find an address from a license plate number either sell old data that may belong to someone else or collect your payment and return nothing useful.

What about license plate lookup websites?

Search for a car plate search and you'll find dozens of sites offering instant results. Some genuinely sell vehicle history reports built from title and insurance data, which can be useful when you're buying a car. But when a site promises a check of the license plate owner's name for free, keep the law in mind: state agencies can't release owner details for curiosity, so those results don't come from an official record request. At best they come from other sources of uneven accuracy. At worst, you pay and get nothing useful.

If you want to look up a plate number for a legitimate reason, the official route in the table costs a few dollars and comes straight from the agency that issued the plate. Worried about the reverse, someone looking up yours? See what someone can do with your license plate number.

Partial plates and plate registration lookups

A partial license plate search is a job for the police, not the public: if you witnessed a crime or a hit-and-run and only caught part of the plate, report what you saw, along with the vehicle's color, make and direction. A plate registration lookup to check that your own registration is current is different: most states let you check your own record online or by mail.

How to find a license plate's details on your own vehicle

If the question is how to find a license plate number for a car you own, look at your registration card, your insurance card, or the last renewal notice from the state. If the plate was lost or stolen, report it to the police and your state agency before ordering a replacement. Want a plate that says something instead? Our custom plate designer previews personalized text and links to each state's availability check, and the registration renewal finder shows when your current plates are due.
