What you can and cannot do with a license plate
You cannot look up someone's name, address, or phone number using only their license plate number through any public database. License plate records are not searchable by the general public—they are held by your state's Department of Motor Vehicles (DMV) and are legally restricted from public access.
However, there are legitimate ways to find someone if you have their plate number. The most direct route is to report the vehicle to law enforcement if you witnessed dangerous driving, a hit-and-run, or another crime. Police can run the plate and contact the owner. If your reason is civil—a minor accident, property damage, or a dispute—you have other options that do not require breaking privacy laws.
The key distinction is whether you have a lawful reason to identify the person. "I want to know who that person is" is not a lawful reason. "They hit my car and left" or "they threatened me" are.
Key Takeaways
- License plate records are private and held only by your state's DMV; no public database lets you search them by plate number.
- If someone hit your vehicle or committed a crime, file a police report with the plate number and let law enforcement do the lookup.
- For minor accidents or property disputes, contact your insurance company—they have legal channels to reach the other driver through their insurer.
- Social media and reverse image searches can sometimes identify a vehicle owner if you have a photo, but this method is unreliable and may not be legal depending on how you use the information.
- Private investigators and skip-tracing services can legally obtain DMV records, but only for clients with a legitimate legal reason (court cases, debt collection, missing persons).
Filing a police report when you have a plate number
If you witnessed a crime—hit-and-run, reckless driving, threats, or property damage—call the non-emergency police line in the jurisdiction where the incident occurred and provide the plate number. The dispatcher will ask for details: what happened, when, where, and what the vehicle looked like. Have the plate number ready and be as specific as possible about the incident.
Police will run the plate through their system and contact the registered owner. If the owner was not driving, they may ask the owner who was. This is the fastest and most legitimate way to identify someone. Keep your police report number; you will need it for insurance claims or if the case goes further.
Do not attempt to confront the person yourself or stake out their address. That can escalate the situation and may expose you to legal liability. Let law enforcement handle the identification and contact.
Using insurance when it is a vehicle accident
If you were in a minor accident and the other driver left the scene or you did not exchange information, contact your own insurance company with the plate number. Your insurer has legal authority to request information about the other vehicle through their industry networks and the other driver's insurer.
Your insurance company will file a claim and use the plate number to identify the other vehicle's owner and their insurer. This process takes longer than a police report—usually one to three weeks—but it works for property damage and minor collisions where no crime was committed.
You will still need to file a police report for a hit-and-run (when the other driver left), even if you plan to go through insurance. Some states require it before your insurer will pay out.
What private investigators can do (and what it costs)
Licensed private investigators can legally obtain DMV records through channels that are closed to the public. They do this for clients with a documented legal reason: ongoing court cases, debt collection, missing persons, or background investigations for employment.
If you hire a PI, expect to pay $500 to $2,000 for a plate lookup and background report, depending on your state and the complexity of the search. The investigator will need to document your reason for the search and may be required to verify it with the court or relevant authority.
This route is expensive and only makes sense if you have a serious legal matter at stake. For most situations—accidents, minor disputes, or curiosity—it is not practical.
Why you cannot use online "reverse plate lookup" services
Websites that advertise "reverse license plate lookup" or "find anyone by plate number" are either scams or they do not actually deliver what they promise. Some collect your payment and provide nothing. Others claim to have access to DMV records but do not—they may pull public information like vehicle make and model (which you can see yourself) but not the owner's identity.
A few services operate in a legal gray area by purchasing data from third-party brokers, but even these cannot reliably return owner information from a plate number alone. The data they sell is often outdated or incomplete.
Avoid these services. They waste money and do not solve the problem. If you have a legitimate reason to find someone, use the police report or insurance route instead.
Using photos and social media when you have a picture of the vehicle
If you have a photo of the vehicle (not just the plate), you can try a reverse image search on Google Images or TinEye. Post the photo in local community groups on Facebook or Nextdoor and ask if anyone recognizes the vehicle. This works surprisingly often in tight-knit neighborhoods.
This method is legal as long as you are not using the information to harass, threaten, or stalk the person. If you find the owner through social media and they confirm they were involved in an incident, you can then decide whether to contact them directly (for minor disputes) or file a police report (for crimes).
Be aware that this approach is slow and unreliable. You may get false leads or no response at all. It works best for distinctive vehicles or in small communities where people know each other's cars.
State-by-state differences in DMV record access
Every state restricts public access to DMV records, but the rules vary slightly. Some states allow limited information (vehicle make and model only) to be released to the public under certain circumstances. Others keep all records completely sealed except for law enforcement and court-ordered requests.
A few states have "owner notification" laws: if you request DMV records through a legitimate legal process, the registered owner is notified that someone looked them up. This protects privacy but also means you cannot secretly identify someone.
Your state's DMV website will list what information is public and what requires a court order or police involvement. If you are unsure, call your local DMV and ask what options exist for your situation.
Frequently Asked Questions
Can I look up a license plate on the DMV website?
No. The DMV website does not have a public search tool for license plates. You cannot enter a plate number and get the owner's information. Only law enforcement, courts, and authorized government agencies can access that database.
What if someone hit my parked car and I have their plate number?
File a police report with the plate number and your insurance company. The police will contact the owner, and your insurer will pursue a claim through their system. Do not try to contact the person yourself or post their plate on social media—that can create legal problems for you.
Is it illegal to use a reverse plate lookup website?
Using the website itself is not illegal, but the information they provide is usually fake or useless. The real legal risk comes if you use whatever information you find to harass, stalk, or threaten someone. Stick with police reports and insurance for legitimate situations.
Can I hire someone to look up a plate number for me?
A licensed private investigator can do it legally if you have a documented reason (court case, debt collection, missing person). Expect to pay $500 to $2,000. For accidents or minor disputes, this is overkill—use police or insurance instead.
What should I do if I see reckless driving but did not get the plate?
Call the non-emergency police line and describe the vehicle, the driver, the time, and the location as accurately as you can. If you remember even part of the plate, include it. Police may be able to narrow it down, especially if the incident happened on a highway with traffic cameras.
