You cannot look up a car owner by license plate yourself — but police, insurance companies, and courts can
A license plate connects to a vehicle registration record that includes the owner's name and address. That record is kept by your state's Department of Motor Vehicles (DMV) or equivalent agency. The DMV does not release this information to the public, even if you have a legitimate reason to find someone. Access is restricted to law enforcement, insurance adjusters, attorneys, and a few other official channels.
If you need to identify a car owner, your path depends on why you need the information. A minor fender bender is handled differently than a hit-and-run, which is handled differently than tracking down someone who owes you money. This guide walks through the real options available to you.
Key Takeaways
- The DMV keeps owner information private and will not release it to private citizens, even with a license plate number.
- If you were in an accident, file a police report and let law enforcement request the registration; your insurance company can also request it on your behalf.
- If you witnessed a hit-and-run or other crime, report it to police with the plate number and any other details you remember.
- If you need information for a legal matter, an attorney can subpoena the registration through the court system.
- Private investigators and skip-tracing services exist but are expensive and work only when you have a legitimate legal reason to search.
What to do if you were in a car accident
If another driver hit your car and you have their license plate, file a police report in the city or county where the accident happened. Provide the plate number, the time, the location, and a description of the vehicle and driver if you saw them. The police report creates an official record and gives law enforcement the authority to look up the registration.
At the same time, contact your own insurance company and give them the plate number. Insurance adjusters have direct access to registration databases through the National Insurance Crime Bureau (NICB) and can pull the owner's information when ready. They will use it to contact the other driver's insurance and begin the claims process. You do not need to wait for police to finish their report — your insurer can move forward with just the plate.
If the other driver left the scene, that is a hit-and-run. Report it to police with all the details you have. Hit-and-run cases are treated as crimes, and police will prioritize looking up the registration and locating the driver.
If you witnessed a hit-and-run or other crime
Call the police non-emergency line (or 911 if the crime is in progress) and report what you saw. Provide the license plate number, the vehicle description, the time, and the location. If you saw the driver, describe them. If you have a photo or video of the plate or vehicle, that is valuable — many police departments now accept reports through their websites with attached images.
Police will investigate using the plate number. They have the authority to contact the DMV and pull the registration, then follow up with the registered owner. You do not need to do anything further — the investigation is now in their hands. If they need more information from you, they will contact you using the phone number you provided in the report.
When you need the information for a legal matter
If you are involved in a lawsuit or small claims case and need to identify a defendant, your attorney can subpoena the vehicle registration from the DMV. A subpoena is a court order that compels the DMV to release information that would normally be private. Your attorney files the subpoena through the court handling your case, and the DMV responds directly to the court or to your attorney.
If you are representing yourself in small claims court, you can also request a subpoena. Ask the court clerk how to file one — the process varies by state and county. Some courts allow you to submit the request on a standard form; others require you to appear in person or have an attorney do it. The court will explain the fee, which is usually under $50.
This route takes longer than insurance or police involvement — typically two to four weeks — but it is available to anyone with a legitimate legal reason to identify someone.
Private investigators and skip-tracing services
Companies that specialize in locating people (called skip-tracers) can sometimes find a car owner using a plate number, but they work only on cases where you have a legal right to the information. They cannot straightforward look it up for you. They typically work for attorneys, debt collectors, or insurance companies — not for private citizens doing a personal search.
If you hire a private investigator, expect to pay $100 to $300 per hour, plus expenses. They will use the plate number along with other public records to build a profile of the owner. This is useful if you are pursuing a lawsuit or have a debt claim, but it is expensive for a straightforward identification. Most people in that situation use the police report or insurance route instead.
Why the DMV keeps this information private
Registration records are protected by state privacy laws and federal law (the Driver's Privacy Protection Act). The reasoning is straightforward: if anyone could look up your address using your license plate, stalking and harassment would be easier. The law makes exceptions for law enforcement, courts, and insurance companies because they have oversight and accountability. A private citizen does not.
Some states have created limited exceptions. A few allow you to request owner information if you can show you were in an accident with the vehicle, but you still cannot do the lookup yourself — you submit a form to the DMV and they decide whether to release it. Check your state's DMV website to see if this option exists where you live.
What not to do
Do not try to use third-party "people search" websites or apps that claim to reverse-lookup license plates. Most of these services do not have access to real registration data — they use outdated public records or make educated guesses based on vehicle type and color. The information they provide is often wrong, and you may end up contacting the wrong person.
Do not approach the vehicle or the driver's home to confront them or demand information. If you are in a dispute, let the official channels (police, insurance, courts) handle it. Confrontation can escalate the situation and may expose you to legal liability.
Frequently Asked Questions
Can I look up a license plate on the DMV website?
No. The DMV website lets you renew your own registration or check your driving record, but it does not have a public lookup tool for other people's plates. You must go through police, insurance, or the court system.
What if I have a photo of the license plate but no other information?
A photo is actually helpful. If you were in an accident, give it to your insurance company — they can use it to confirm the plate number when they request the registration. If you witnessed a crime, attach the photo to your police report.
How long does it take for insurance to get the owner's information?
Insurance companies usually have the information within one to three business days. They will contact the other driver's insurance directly once they have the registration details. Police reports take longer — typically one to two weeks — because police investigate rather than straightforward look up a name.
Can I find a car owner if the accident happened in a different state?
Yes. Your insurance company can request the registration from any state's DMV. If you are filing a police report, file it in the state where the accident occurred, and that state's police will look up the out-of-state registration. The process is the same; it just takes slightly longer because the request crosses state lines.
What if the car is registered to a business instead of a person?
The registration will show the business name and address. If you need the individual owner's name, that information is not on the registration — you would need to contact the business directly or have an attorney subpoena additional records from the business registration office.
