What a license plate search can and cannot tell you
A license plate search looks up the registered owner of a vehicle and sometimes its history — but what you can actually find depends on who you are and what you're searching for. If you own the car or have the owner's permission, you can get the registered owner's name and address from your state's Department of Motor Vehicles (DMV). If you don't have permission, the information available to you is much more limited, and some searches are illegal.
The most common reason people search a plate is to identify a hit-and-run driver, report reckless driving, or check a used car before buying it. Each situation has different legal rules about what information you can access and how you can get it.
Key Takeaways
- Your state's DMV can provide the registered owner's name and address if you own the vehicle or have written permission from the owner.
- Police can search plates for law enforcement purposes, but private citizens cannot legally request that information in most states.
- Third-party vehicle history services like Carfax and AutoCheck pull from insurance claims, accident reports, and service records — not from the DMV — and do not require the owner's permission.
- If you witnessed a hit-and-run or dangerous driving, reporting to police is the legal way to have the plate searched; you should not attempt to search it yourself.
- Used car buyers can run a vehicle history report without the seller's permission, but cannot get the current owner's personal information from the DMV.
Searching through your state's DMV
Every state's DMV maintains a database of registered vehicles and their owners. To search it, you typically need to visit the DMV in person, call, or use an online portal — the method and cost vary by state. Some states charge $5 to $20 per search; others offer it free to vehicle owners.
You can request information about a vehicle you own, or about any vehicle if you have the owner's written consent. A few states allow searches for specific reasons — such as verifying a vehicle's title before purchase — but most require either ownership or permission. The DMV will provide the registered owner's name, address, and sometimes the vehicle identification number (VIN) and title status.
If you're buying a used car and want to verify the seller's identity or check for liens, contact the DMV directly and ask what information they can provide for a pre-purchase search. Some states have a dedicated process for this.
Vehicle history reports from third-party services
Services like Carfax, AutoCheck, and LexisNexis pull vehicle history from insurance claims, accident reports, service records, and auction data — not from the DMV. These reports do not require the owner's permission and are legal for anyone to order. They cost between $15 and $50 per report, though some dealers provide them free.
A vehicle history report tells you whether the car has been in accidents, had insurance claims, been flooded, had a title branded as salvage, or been recalled. It does not tell you the current owner's name or address. If you're shopping for a used car, running a history report on the VIN is the standard way to check the vehicle's background.
These services update their databases continuously, but they only know what has been reported to insurance companies, repair shops, and auction houses. A minor accident that was paid for in cash may not appear on any report.
Why you cannot legally search a plate for personal reasons
In most states, searching the DMV database to find someone's personal information — even if you have their license plate — is illegal without a legitimate reason. The Driver's Privacy Protection Act (DPPA), a federal law, restricts access to DMV records. States can only release registered owner information to law enforcement, insurance companies, vehicle manufacturers, and a few other authorized parties.
If you witnessed a hit-and-run, dangerous driving, or a crime, the legal path is to report it to police with the plate number. Police have the authority to search the DMV and identify the driver. You should not attempt to search the plate yourself or post it online asking others to identify the driver, as this can expose you to civil liability.
Some people use online "people search" sites that claim to search plates, but these services do not have access to current DMV records. They may return outdated information, incorrect matches, or nothing at all. Paying for these searches is usually a waste of money.
What to do if you witnessed a hit-and-run or dangerous driving
If you have a license plate number from an incident, contact your local police non-emergency line or file a report online through your city or county website. Provide the plate number, the date and time of the incident, the location, and a description of what happened. Police will search the DMV to identify the registered owner and follow up.
If the incident involved injury or significant property damage, call 911 instead. Keep any photos, video, or witness contact information you have. Do not attempt to contact the driver yourself or post the plate on social media — this can complicate the police investigation and may expose you to legal risk.
Some states have hit-and-run hotlines or online reporting systems that are faster than calling the local precinct. Check your state's DMV or highway patrol website for the fastest way to report in your area.
Buying a used car: what searches are available to you
Before buying a used car, you have two main searches available: a vehicle history report (which you can order without permission) and a title search through your state's DMV (which you can usually do for a small fee if you're considering purchase).
Order a vehicle history report using the VIN, which the seller should provide. This shows accidents, insurance claims, recalls, and title status. Then contact your state's DMV and ask whether they offer a pre-purchase title search. Some states allow this; others require you to wait until you own the vehicle. A title search confirms the seller is the registered owner and that there are no outstanding liens.
You cannot use a plate search to verify the seller's identity or find their personal information. If the seller seems evasive about providing the VIN or title documents, that is a red flag — walk away from the sale.
State-by-state differences in plate search rules
Each state's DMV has different policies about who can search plates and what information is released. Some states offer online searches to vehicle owners; others require an in-person visit. Some charge a fee; others do not. A few states have broader exceptions to privacy rules for specific reasons like pre-purchase verification.
Before attempting a search, visit your state's DMV website and look for "vehicle registration search" or "owner information request." The site will explain what you need to provide, who is allowed to search, and what the cost is. If the information is not clear, call the DMV directly.
If you're moving to a new state or buying a car from out of state, remember that you can only search the DMV in the state where the vehicle is registered. A plate from California cannot be searched through the New York DMV.
Frequently Asked Questions
Can I find out who owns a car just from the license plate?
Only if you own the vehicle or have the owner's written permission. Your state's DMV can provide the registered owner's name and address, but they will not release this information to the general public. If you need to identify a driver for a legitimate reason like a hit-and-run, report it to police.
Are online plate search websites real?
Most online "plate search" sites do not have access to current DMV records. They may return outdated information, guesses based on public records, or nothing at all. Paying for these searches is usually not worth the cost. For a used car, order a vehicle history report instead, which pulls from real insurance and accident data.
What information does a vehicle history report show?
A vehicle history report shows accidents, insurance claims, flood damage, title status (salvage, rebuilt, etc.), recalls, and service records. It does not show the current owner's name or address. You can order one using the VIN without the owner's permission.
Is it legal to post a license plate on social media to find the driver?
No. Posting a plate online to identify someone can expose you to civil liability and may interfere with a police investigation. If you witnessed a crime or hit-and-run, report it to police directly with the plate number.
How much does it cost to search a plate through the DMV?
The cost varies by state, from free to $20 per search. Some states charge vehicle owners nothing but charge non-owners a fee. Check your state's DMV website for the exact price and whether you can search online or must visit in person.
