Your registration number is printed on your registration card and on your vehicle's license plate

Your vehicle registration number — also called a registration plate number, license plate number, or plate number — appears in two places you can reach right now. The easiest is your registration card, the document your state's motor vehicle department mailed to you when you registered the vehicle. It's a small card, usually wallet-sized, and the number is printed clearly on the front. The second place is the physical plate bolted to your vehicle: on the front bumper, rear bumper, or both, depending on your state.

The format varies by state. Most states use a combination of letters and numbers — for example, ABC1234 or 1ABC234. Some states include a county code or a special prefix. The number on your card and the number on your plate are the same; they're just two copies of the same registration.

Key Takeaways

  • Your registration card, mailed by your state's motor vehicle department, displays your registration number on the front in large print.
  • The same number is stamped on your vehicle's license plate, mounted on the front and/or rear bumper.
  • If you've lost your registration card, you can request a replacement from your state's DMV or equivalent agency for a small fee.
  • Your registration number is different from your Vehicle Identification Number (VIN), which is a 17-character code found on your dashboard and in your paperwork.

Checking your registration card

Open your glove compartment or wallet and look for the registration card your state issued. It's typically a laminated card about the size of a credit card, printed on white or colored stock. The registration number is printed in the upper right or upper left corner, depending on your state's format.

The card also lists your name, the vehicle's make and model, the VIN, and the expiration date of your registration. If you keep your card in your vehicle, it's usually in the glove compartment, visor pocket, or center console. If you keep it at home, check the file where you store your vehicle documents.

Reading the number from your license plate

Walk to the front or back of your vehicle and look at the plate. The registration number is the entire sequence of letters and numbers on that plate. Write it down exactly as it appears — capitalization and spacing matter when you're providing it to a government agency or insurance company.

If your plate is damaged, faded, or missing, contact your state's motor vehicle department to request a replacement. Most states charge a replacement fee, usually between $5 and $25. You'll need to provide your current registration card or proof of ownership to get a new plate.

What to do if you've lost your registration card

If you can't find your registration card but you know your registration number, you can still use the plate number. If you need a replacement card, contact your state's Department of Motor Vehicles (DMV) or equivalent agency — the name varies by state. You can usually request a duplicate through their website, by mail, or in person at a local office.

You'll typically need to provide your driver's license number, VIN, or current plate number to confirm your identity. Processing time ranges from a few days to a few weeks, depending on your state. Some states offer expedited processing for an additional fee.

Understanding the difference between registration number and VIN

Your registration number and your Vehicle Identification Number (VIN) are not the same thing. Your registration number is what appears on your plate and registration card — it's assigned by your state and changes if you move to a different state or register a different vehicle. Your VIN is a 17-character code unique to your specific vehicle, assigned by the manufacturer, and it never changes.

You'll find your VIN on your registration card, your insurance documents, and on a small metal plate on your dashboard (usually visible through the windshield on the driver's side). You'll also find it on the driver's side door jamb. When you're asked for your "registration number," use the plate number. When you're asked for your VIN, use the 17-character code.

Using your registration number for insurance and government forms

Insurance companies, government agencies, and service providers often ask for your registration number. This is the number from your plate or registration card. Have it ready when you're filing a claim, renewing your registration, paying a traffic fine, or updating your address with your state's motor vehicle department.

Some online forms ask for your "plate number" or "license plate number" — these are the same as your registration number. If a form asks for your "registration number" and you're unsure which number to enter, look for context clues: if the form is asking about your vehicle's current status or your current registration, use your plate number.

Frequently Asked Questions

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

Yes. Your registration number and your license plate number are the same thing. The number printed on your physical plate is your registration number. It's also printed on your registration card.

What if my registration number has letters I can't read on the plate?

Check your registration card — the number is printed there in clear text. If the plate is too damaged or faded to read, contact your state's DMV to request a replacement plate. Bring your registration card or proof of ownership.

Can I look up my registration number online?

Most states allow you to look up your registration information through their DMV website if you provide your driver's license number, VIN, or other identifying information. Some states charge a small fee for this service. Check your state's motor vehicle department website for the exact process.

Do I need my registration number to renew my registration?

You'll need either your registration number, your VIN, or your driver's license number to renew. Most states send you a renewal notice in the mail that includes your registration number, making renewal easier. You can also renew online or by mail using any of these identifiers.

What if I moved to a new state — does my registration number change?

Yes. When you register your vehicle in a new state, you'll receive a new registration card and a new license plate with a new registration number. Your old plate and registration are no longer valid. Contact your new state's DMV to register your vehicle within the timeframe required by that state.
