Your license plate number is printed on the metal plate bolted to the front and back of your vehicle

The license plate number — also called a registration number or tag number — is a combination of letters and numbers unique to your car. It appears on the rectangular metal plate mounted on your vehicle's front bumper and rear bumper. Every state formats these differently. Some use three letters followed by three numbers; others mix them throughout. The exact format depends on which state issued your plate.

You need this number for insurance paperwork, vehicle registration renewal, parking permits, toll accounts, and any time you report your car to police or a government agency. It is not the same as your Vehicle Identification Number (VIN), which is a longer code stamped into the car's frame and visible on your dashboard.

Key Takeaways

  • Your license plate number is on the metal plate bolted to your car's front and rear bumpers.
  • If your plate is missing or damaged, your state's Department of Motor Vehicles can issue a replacement.
  • Your registration card, insurance documents, and vehicle title all show your plate number if you cannot see the physical plate.
  • The plate number is different from your VIN, which is a longer code stamped into your vehicle's frame.

Check your registration card or insurance documents

If you cannot see your physical plate clearly or it is damaged, your vehicle registration card has the plate number printed on it. This is the small card your state's Department of Motor Vehicles mailed to you when you registered your car. Keep it in your glove compartment. The plate number appears near the top or bottom of the card, depending on your state.

Your insurance documents also list the plate number. Check your insurance card, policy documents, or your insurer's online account. Your vehicle title — the legal ownership document — includes it as well. If you have any of these documents handy, you can find the number without going outside.

Look at your vehicle's dashboard

Some vehicles display the plate number on a sticker inside the driver's side door jamb or on the dashboard itself. Open your driver's side door and look at the frame where the door closes. You may see a small label with vehicle information including the plate number. This label is required in some states but not all, so it may not be present on your car.

Check your dashboard near the windshield as well. Older vehicles sometimes have a registration sticker visible from outside that includes the plate number, though modern vehicles have moved away from this practice.

Contact your state's Department of Motor Vehicles

If you cannot locate your plate number through any of these methods, your state's Department of Motor Vehicles can tell you what it is. You will need to provide your driver's license number or VIN. Most states let you look this up online through their DMV website without calling. Search "[your state] DMV vehicle information lookup" to find the online tool.

If an online lookup is not available in your state, call your local DMV office or visit in person. Bring your driver's license and proof of vehicle ownership (your title or registration card). The staff can print out your registration information, which will show your plate number.

What to do if your plate is missing or damaged

If your license plate has been stolen, is damaged, or is illegible, you need to report it to your state's DMV and request a replacement. The process and cost vary by state — some charge a small fee, others do not. Most states let you order a replacement online through their DMV website, by mail, or in person at a DMV office.

When you request a replacement, the DMV will either reissue the same number on a new plate or assign you a new number. Ask which will happen when you submit your request. Until your replacement arrives, you should not drive the vehicle in most states, as a missing or illegible plate can result in a traffic citation. Some states allow a temporary permit while you wait for the replacement to arrive.

Understand the difference between your plate number and your VIN

Your Vehicle Identification Number (VIN) is a 17-character code that identifies your specific car. It is stamped into the metal frame of your vehicle and is visible on your dashboard at the base of the windshield on the driver's side. You can also find it on your title, registration card, and insurance documents. The VIN includes information about the car's manufacturer, model, year, and production sequence.

Your plate number, by contrast, is issued by your state and changes if you move to a different state or request a new plate. The VIN stays with the vehicle for its entire life. Government agencies and insurance companies use the VIN to track the car's history. Police use the plate number to identify the vehicle on the road. You need both numbers for different purposes, but they are not interchangeable.

Frequently Asked Questions

Can I look up my license plate number online?

Most states offer an online DMV portal where you can look up your vehicle information, including your plate number. You will need your driver's license number, VIN, or registration number to search. Visit your state's official DMV website and look for a "vehicle information lookup" or "registration status" tool.

What if I just bought a used car and do not know the plate number?

The plate number is on the metal plate attached to the car. If the car came with plates, look at the front and rear bumpers. If the seller removed the plates, contact your state's DMV with the VIN to find out what the previous plate number was, or ask the seller directly. You will need to register the vehicle in your name and may receive new plates.

Is my license plate number the same as my registration number?

They are related but not identical. Your registration number is an internal DMV identifier for your vehicle's registration record. Your plate number is what appears on the metal plate. Both are printed on your registration card, and you may need either one depending on what you are doing.

Do I need my plate number to renew my driver's license?

No. Renewing your driver's license requires your driver's license number, not your plate number. However, if you are renewing your vehicle registration at the same time, you will need your plate number or VIN for that transaction.
