What Can Someone Do With Your License Plate Number?
A plate is visible to everyone, but the DMV record behind it is protected by federal law.
By Siddharth ShankarUpdated October 22, 2026Your plate number is visible on the street, but under the US Driver’s Privacy Protection Act a state motor vehicle department generally cannot disclose the personal information in your record to anyone, apart from listed permitted uses such as government agencies, litigation, insurers, towing and tolls. Personal information includes name, address, phone number, driver ID number, photo and Social Security number. Highly restricted information needs your express consent. You mainly control what you post and share yourself.

Anyone can read your plate while you drive or park. What matters is what they can link that number to. In the US, federal law limits that link, but it does not make the plate invisible.
The law behind your DMV record
The Driver’s Privacy Protection Act, 18 U.S.C. section 2721, says a state motor vehicle department, and its officers, employees and contractors, may not knowingly disclose or make available personal information from a motor vehicle record, except as the law allows. A motor vehicle record is any record that pertains to a driver’s permit, vehicle title, vehicle registration or state identification card.
What counts as personal information
Section 2725 defines personal information as information that identifies an individual. It includes a photo, Social Security number, driver ID number, name, street address (but not the five-digit ZIP code), telephone number, and medical or disability details. It excludes information on vehicle accidents, driving violations and driver’s status.
A narrower group, highly restricted personal information, is a photograph or image, Social Security number, and medical or disability information. Disclosing it generally needs your express consent, with a few listed exceptions.

Who may still get the data
The law lists permitted uses. They include:
- use by a government agency, court or law enforcement agency,
- use in civil, criminal, administrative or arbitral proceedings,
- use by insurers for claims investigation, antifraud, rating or underwriting,
- notice to the owners of towed or impounded vehicles,
- operation of private toll transportation facilities,
- research, as long as the data is not published or used to contact people,
- verification of information by a legitimate business, to prevent fraud or recover debts,
- uses where the person has given express consent.
So a stranger who notes your plate cannot simply ask the DMV for your home address. A party with a listed purpose, such as an insurer or someone in a lawsuit, can.
Where plate exposure really happens
The risk is less the DMV and more what you share yourself:
- Photos. A plate visible in a post about your new car, your driveway or a road trip ties a vehicle to a place and a time.
- Listings. Selling a car online with the plate showing links the listing to you.
- Combined clues. A plate plus a street plus a face can help someone work out where you live. See what doxxing is and how to protect yourself.
How to reduce the risk
- Blur or crop plates before you post photos or listings.
- Strip location data from photos. See how photos reveal your location.
- Be careful with who you give your plate to, such as parking apps, and read what they say they do with it.
- If someone follows you or you feel unsafe, contact the police rather than trying to trace a plate yourself.
State rules differ
The federal act sets a floor, and states add their own rules. Check your state motor vehicle agency for how to limit sharing of your record. This guide is general information, not legal advice.
