You'll need to contact your state's motor vehicle department, but they won't give the information to you directly

If you have a license plate number and want to know who owns the vehicle, you cannot look it up yourself through a public database. Your state's Department of Motor Vehicles (or equivalent agency — it may be called the Secretary of State or Registry of Motor Vehicles depending on where you live) keeps that information private. However, there are legitimate ways to request it, and the process depends on why you need it and what state you're in.

The most direct route is to contact your state's DMV and explain your reason. If your reason falls into certain categories — you were in a hit-and-run accident, you witnessed a crime, you need it for a legal proceeding — the DMV may release the owner's information or may pass your information to the owner so they can contact you. Some states have formal processes for this; others handle requests case by case.

Key Takeaways

  • Your state's DMV does not release vehicle owner information to the public, but will consider requests if you have a legitimate reason like a traffic accident or witnessed crime.
  • A hit-and-run accident is the most common reason DMVs will help; you'll typically need to file a police report first and reference the report number when you contact the DMV.
  • If you need the information for a legal case, an attorney or the court can request it through formal channels that carry more weight than a personal request.
  • Private investigators and background check services can sometimes locate owner information, but they operate outside the DMV system and may charge a fee.
  • Posting the plate number on social media or neighborhood apps is not reliable and can create legal problems if the post is seen as harassment or defamation.

What counts as a legitimate reason to request owner information

States vary in what they consider a valid reason, but most will consider requests related to traffic accidents, property damage, or crimes. If you were hit by another vehicle and the driver left the scene, you have a strong case. File a police report first — this creates an official record and gives you a report number. When you contact your DMV, reference that report number. The DMV is more likely to help when law enforcement is already involved.

If you witnessed a crime — a vehicle was used in a theft, assault, or other incident — contact the police department in the jurisdiction where it happened and file a report. Again, get the report number. Then contact your DMV with that number. Some states will release the owner's name and address to you; others will contact the owner on your behalf and ask them to reach out to you.

If you need the information for a lawsuit or insurance claim, your attorney can request it through legal discovery or subpoena, which carries official authority. Insurance companies also have channels to request owner information when processing a claim.

How to contact your state's DMV about a license plate

Start by visiting your state's official DMV website. Look for a section on "records requests," "vehicle information requests," or "hit-and-run procedures." Most states have a dedicated form or phone line for these requests. Some allow you to submit a request online; others require a phone call or a written letter.

When you contact them, have the following information ready: the license plate number, the state where the plate is registered, the date and time of the incident (if applicable), the location, and your reason for the request. If there's a police report, have the report number available. Be clear and factual about what happened. DMV staff will tell you whether your reason qualifies and what the next step is.

Response times vary. Some states respond within days; others take several weeks. If your reason is urgent — for example, you need the information for an active police investigation — mention that when you call.

When police involvement speeds up the process

If law enforcement is investigating the incident, the process is usually faster and more direct. Police departments have their own channels to request vehicle owner information from the DMV, and those requests are prioritized. If you've filed a police report, the officer handling your case may be able to look up the owner's information themselves or request it on your behalf.

For hit-and-run accidents, many police departments will contact the vehicle owner as part of their investigation. You don't always need to contact the DMV yourself — the police may do it for you. Ask the officer taking your report whether they'll handle the lookup or whether you need to follow up with the DMV separately.

Private services and what they can and cannot do

Private investigators and some background check websites claim they can look up vehicle owner information. Some of these services do have access to databases that include registration data, though the information may be outdated or incomplete. These services typically charge a fee — anywhere from a few dollars to twenty or more dollars per lookup.

The catch is that these services operate in a legal gray area. They may have purchased data from public records, but the accuracy and legality of how they obtained it varies. If you use one, you're relying on a third party, and there's no may provide the information is current or correct. For a legitimate need like a hit-and-run accident, it's better to go through official channels — the DMV or police — because the information will be reliable and your request will be documented.

What not to do: social media and public posts

Posting a license plate number on social media, neighborhood apps like Nextdoor, or online forums might seem like a quick way to find the owner, but it creates real problems. First, the information you get back is unverified and could be wrong. Second, if your post is seen as accusatory or if you're asking people to "shame" or contact the owner, you could face legal liability for harassment or defamation — especially if the plate number belongs to the wrong person or if the situation is more complicated than you realize.

Even if your intentions are good, a public post can escalate a situation that should stay between you, the other party, and authorities. If you need to find someone, use the official channels available to you.

What happens after you get the owner's information

Once you have the owner's name and contact details, what you do next depends on your situation. If it's a hit-and-run or crime, you've already involved police, so your role is mostly done. If it's a property damage dispute or a traffic incident where you need to exchange information, you can contact the owner directly or go through your insurance company.

Keep records of all communication. If the owner disputes what happened or refuses to cooperate, you may need those records for insurance, small claims court, or police follow-up. Stay factual and avoid accusations — stick to what you observed and what you need (repair costs, insurance information, etc.).

Frequently Asked Questions

Can I look up a license plate number online for free?

No. Your state's DMV does not publish a public database where you can search by plate number. Some websites claim to offer free lookups, but they either don't work, provide outdated information, or require you to pay after you enter the plate number. The only free way is to contact your DMV directly with a legitimate reason.

What if I was in a minor accident and the other driver drove away before we exchanged information?

That's a hit-and-run, even if it was minor. File a police report and include the license plate number. Once you have a report number, contact your DMV or give the report number to your insurance company. Both can use it to request the owner's information.

Do I need a lawyer to get vehicle owner information?

Not for a hit-and-run or crime report. The DMV will work with you directly if you have a police report number. You only need a lawyer if you're pursuing a civil lawsuit and need the information through legal discovery, though your attorney can handle that request for you.

What if the license plate is from a different state?

Contact that state's DMV using the same process. Each state maintains its own registration database. You'll need to reach out to the DMV in the state where the plate is registered, not your home state.

Can I get the owner's information if I just want to return something they lost?

Most DMVs will not release information for that reason alone. However, you can contact the police non-emergency line and ask if they'll pass along your contact information to the owner. Some police departments will do this as a courtesy. Alternatively, if the vehicle was parked somewhere, you might leave a note on the windshield.
