What you can and cannot find out from a license plate
You cannot look up a car owner's name, address, or phone number using only a license plate number. Most states keep vehicle registration records private to protect owners from harassment and identity theft. The registered owner's personal information is available only to law enforcement, insurance companies, and in some cases, attorneys handling civil cases.
What you can do is report the vehicle to police if you witnessed a hit-and-run, dangerous driving, or a crime. You can also contact your insurance company if you were in an accident and need the other driver's information. If you have a legitimate legal reason — such as a lawsuit or property damage claim — an attorney can request the information through proper legal channels.
If you straightforward want to identify a vehicle for personal reasons, there are a few limited options that work within privacy laws, but they depend on what actually happened and why you need the information.
Key Takeaways
- State motor vehicle departments do not release owner information to the public, even with a license plate number.
- Police can look up vehicle owners and will do so if you report a crime, hit-and-run, or dangerous driving.
- If you were in an accident, your insurance company can obtain the other driver's information and contact details.
- An attorney can request vehicle registration records through legal discovery if you have a civil case against the owner.
- Private investigators and online services that claim to identify owners from plate numbers are either unreliable or accessing data illegally.
Report to police if you witnessed a crime or hit-and-run
If a vehicle was involved in a hit-and-run, dangerous driving that endangered you, or any other crime, call your local police non-emergency line or file a report online through your city or county police department website. Provide the license plate number, the time and location, a description of what happened, and any details about the vehicle itself (color, make, model, damage).
Police have direct access to state motor vehicle records and can identify the registered owner. They will contact the owner if the report warrants investigation. You do not need to know the owner's name to file a report — the plate number is enough for police to begin.
If the incident was serious or you feel unsafe, call 911 instead of the non-emergency line. Keep a record of your report number for your own files.
Use your insurance company if you were in an accident
If you were in a vehicle accident and the other driver left the scene or you did not exchange information, provide your insurance company with the license plate number. Your insurer has legal authority to request the other vehicle's registration information from the state motor vehicle department.
Your insurance company will use this information to contact the other driver's insurer, file a claim, and determine fault. You do not need to contact the owner yourself — the insurance companies handle the exchange of information. This process typically takes a few days to a week.
If you do not have collision or comprehensive coverage, you can still report the accident to police and provide them with the plate number. Police reports create an official record that may help if you pursue a small claims case later.
Contact an attorney if you have a legal claim
If you are pursuing a civil lawsuit or have a legitimate legal claim against a vehicle owner — such as property damage, a contract dispute, or a personal injury case — your attorney can request the vehicle registration information through the discovery process. This is a formal legal procedure that requires filing with the court.
Your attorney will file a motion or subpoena requesting the information from the state motor vehicle department. The court must approve the request, and the information is released only to the attorney, not to you directly. This process takes several weeks and requires that a lawsuit already be filed or in preparation.
Do not attempt to obtain this information on your own or hire someone to do so outside of legal channels. Unauthorized access to registration records is illegal in most states.
Why online lookup services do not work
Many websites advertise the ability to find a car owner by license plate for a fee. These services are either selling outdated or inaccurate data, or they are accessing information illegally. State motor vehicle departments do not license or authorize these services to resell registration records.
Some of these sites may have scraped publicly available information from court records, accident reports, or other sources, but this data is often incomplete or wrong. Others may be collecting payment without delivering any usable information at all. Paying for these services wastes money and does not give you legitimate access to current registration data.
If a service claims to have "when ready" access to private registration records, it is not operating legally. Legitimate access requires a court order, law enforcement authority, or an insurance company's request — not a credit card payment to a third-party website.
What to do if you need to identify a vehicle for other reasons
If you witnessed something unusual or suspicious but no crime occurred, you can still contact your local police non-emergency line and describe what you saw. Police may investigate if the behavior suggests criminal activity, even if you only have a plate number.
If you are concerned about a vehicle parked near your home or business, contact your local code enforcement or parking authority. They can check whether the vehicle is registered and whether it is parked legally.
If you are trying to locate someone you know and only have their license plate, that is not a legitimate reason for police to release their information. In that case, you would need to contact them through other means — mutual friends, social media, or hiring a licensed private investigator who operates within state law.
Understanding state privacy laws and your rights
Most states passed laws restricting public access to vehicle registration information after the Driver's Privacy Protection Act (DPPA) became federal law in 1994. The DPPA prohibits states from selling or releasing registration records to the public without the vehicle owner's permission, with narrow exceptions for law enforcement, courts, and insurance companies.
Some states allow limited access to registration information in specific situations — for example, if you are involved in an accident or have a court order. A few states have "open records" laws that allow broader access, but even these typically require a formal request and a stated legitimate purpose.
Your state's motor vehicle department website usually explains what information is public and what requires a court order or law enforcement request. If you are unsure whether you have a legitimate reason to obtain someone's information, contact an attorney before pursuing it.
Frequently Asked Questions
Can I find out who owns a car if I have their license plate number?
Not through public records. State motor vehicle departments keep registration information private. Police can look it up if you report a crime or hit-and-run. Your insurance company can obtain it if you were in an accident. An attorney can request it through a court order if you have a legal case.
What should I do if someone hit my car in a parking lot?
Report it to police and provide the license plate number if you have it. Also contact your insurance company with the plate number and details of what happened. Your insurer will request the other driver's information from the state motor vehicle department. If you have collision coverage, your insurer will handle the claim.
Is it illegal to use a website that claims to identify car owners by plate?
Using such a website is not illegal, but the information is often inaccurate or obtained through questionable means. The website itself may be operating illegally if it is accessing current state registration records without authorization. You are better off reporting to police or contacting your insurance company instead.
Can a private investigator find a car owner's information?
A licensed private investigator can request information through legal channels if you have a legitimate reason, but they cannot access state motor vehicle records directly. They may use public records, court documents, or other legal sources. Hiring a private investigator is expensive and only makes sense if you have a serious legal claim.
What if I saw a car doing something dangerous but did not get the driver's name?
Call your local police non-emergency line and provide the license plate number, time, location, and description of what happened. Police will investigate if the behavior suggests a crime or traffic violation. You do not need to identify the driver yourself — police will do that if they decide to follow up.
