You cannot find someone by their license plate number on your own
A license plate number alone will not lead you to a person's name, address, or phone number through any public database or search tool. The vehicle registration records that connect a plate to an owner are kept by your state's Department of Motor Vehicles (DMV) and are not open to the public. Even if you know the exact plate, you cannot walk into a DMV office or call and ask them to look it up for you.
This protection exists by law. States treat vehicle registration as private information, similar to how your driver's license details are private. The only people who can request this information are law enforcement, insurance companies handling a claim, and in some cases, attorneys involved in a legal matter. A private citizen — even if they were hit by the car or witnessed an accident — cannot straightforward ask the DMV to identify the driver.
Understanding what is actually possible will save you time and help you know when you need to involve someone else, like police or your insurance company.
Key Takeaways
- State DMV records that link license plates to owners are not public, and the DMV will not release this information to private citizens under any circumstances.
- If you were in an accident or witnessed a crime, police can look up a plate number and contact the owner on your behalf.
- Insurance companies can request registration information when processing a claim, and they will handle contacting the other driver.
- Private investigators and attorneys can sometimes request this information through legal channels, but only for legitimate purposes like litigation or court-ordered investigations.
- Posting a plate number online or hiring someone to look it up may violate privacy laws or terms of service, even if your reason seems justified.
When police can look up a plate for you
If you were involved in a hit-and-run accident, witnessed a crime, or have a legitimate safety concern, you can report the plate number to local police. Officers have direct access to state registration databases and can identify the vehicle owner. They will then decide whether to contact the owner, issue a citation, or open an investigation depending on what happened.
To report a plate number to police, call the non-emergency line for your city or county (not 911 unless there is when ready danger). Have the plate number ready, along with the date, time, and location of the incident, and describe what you saw. If it was a traffic accident, you may also file a report online through your local police department's website. Police will not give you the owner's information directly, but they will contact the owner themselves and may ask them to reach out to you.
This is the fastest and most reliable way to identify someone by their plate if you have a legitimate reason. Police handle it regularly and have the legal authority to do so.
How insurance handles plate lookups after an accident
If you were in a car accident and have the other driver's plate number but not their name or contact information, report the plate to your own insurance company. Your insurer can request the registration information from the other vehicle's state DMV as part of the claims process. Insurance companies have legal standing to make these requests because they need the information to process the claim and determine fault.
When you file a claim, tell your insurance agent or adjuster that you have the plate number but not the driver's information. Provide the plate, the date and time of the accident, and the location. Your insurer will handle the lookup and will contact the other driver's insurance company directly. You do not need to do anything else — your insurance company manages the entire process from there.
This route works even if the other driver left the scene, as long as you have an accurate plate number and can describe where and when the accident happened. Insurance companies do this constantly and have established procedures for it.
Why you should not try to look up a plate yourself
Several websites claim to offer "reverse license plate lookup" services. These sites do not have access to official DMV records — they cannot, because that information is not public. Instead, they may compile data from public records, social media, or other sources, and their results are often inaccurate or outdated. More importantly, using these services may violate the terms of service you agreed to when you created an account with the site, and in some cases may violate state privacy laws.
Posting a plate number on social media or in a public forum to ask others to identify the driver carries similar risks. Even if your reason seems justified — you were hit by the car, you witnessed something concerning — you could face legal consequences for attempting to identify someone without proper authority. The person you are trying to identify could also sue you for harassment or invasion of privacy.
The legal and safe routes — police, insurance, or an attorney — exist specifically because they have the authority to do this work. Using them protects you and ensures the information is handled correctly.
What private investigators and attorneys can do
If you are involved in a lawsuit or have hired an attorney, your lawyer can request vehicle registration information through legal discovery or subpoena. Private investigators working on behalf of an attorney or law enforcement can also access this information as part of an authorized investigation. These professionals have legal standing and proper channels to make the request.
If you think you need this level of help — for example, because you were in a hit-and-run and police have not made progress — you can consult with an attorney. They can advise whether a private investigator is necessary and what it might cost. Many attorneys offer free initial consultations, so you can ask about your options without committing to anything.
What information is actually on a license plate
A license plate itself contains only the registration number and the state. It does not include the owner's name, address, phone number, or any personal information. The plate is straightforward a unique identifier that the DMV uses to look up the registration in its database. Without access to that database, the plate number alone tells you nothing about who owns the vehicle.
This is why the plate number is not useful on its own for finding someone. You need the DMV database to connect the plate to a person, and that database is restricted to authorized users. Knowing the plate number is the starting point, but you cannot complete the process without going through an official channel.
Frequently Asked Questions
Can I ask the DMV directly to look up a plate number for me?
No. The DMV will not provide registration information to private citizens under any circumstances. Even if you explain that you were in an accident or have a safety concern, the DMV's policy is to refer you to police. Call your local police non-emergency line instead.
What if I was hit by a car and the driver did not stop?
Report the plate number to police when ready, along with the date, time, location, and a description of the vehicle and driver if you have one. Also report the incident to your insurance company. Police will investigate and contact the driver; your insurance will handle the claim. Do not try to contact the driver yourself.
Is it illegal to use a reverse license plate lookup website?
Using these sites may violate their terms of service, and depending on your state and what you do with the information, it could expose you to legal risk. The safer choice is to report the plate to police or your insurance company, both of which have legal authority to look it up.
Can I hire a private investigator to find someone by their plate?
A private investigator working on behalf of an attorney or law enforcement can access registration information through legal channels. If you need this level of help, consult an attorney first. They can advise whether it is necessary and refer you to an investigator if appropriate.
What if someone is harassing me and I only have their plate number?
Report the harassment and the plate number to police. Provide details about what happened, when, and where. Police can identify the vehicle owner and investigate. Do not attempt to identify or contact the person yourself, as that could escalate the situation.
