Your registration number is on your registration card and vehicle title

Your registration number (also called a registration plate number or plate number) appears in two places you already have: your vehicle registration card and your vehicle title document. On the registration card, it is printed near the top or bottom, depending on your state. On the title, it appears in a field labeled "Registration Number" or "License Plate Number." Both documents show the same number.

If you have lost both documents, your state's Department of Motor Vehicles (DMV) can look up the number using your Vehicle Identification Number (VIN) and driver's license. You can call your state DMV, visit in person, or use their online portal if available. Some states let you look it up yourself on their website by entering your VIN and last name.

Key Takeaways

  • Your registration number is printed on your registration card and title document in a clearly labeled field.
  • If you cannot find your documents, your state DMV can retrieve the number using your VIN and driver's license information.
  • Many state DMV websites have a lookup tool where you can search by VIN without visiting an office.
  • Your registration number is different from your VIN — the registration number is tied to your current state registration, while the VIN is permanent to the vehicle.

Check your registration card first

The registration card is the fastest place to look. It is a small wallet-sized card that came with your vehicle when you registered it, or when you renewed your registration. The registration number is usually printed in large text near the top of the card, or sometimes at the bottom. It matches the number on your license plate.

If your card is damaged or faded, the number may still be readable. Hold it under good light or take a photo with your phone to see it clearly. If the card is completely illegible, move to your title document.

Look at your vehicle title if you cannot find the card

Your title is the legal ownership document for your vehicle. It contains your registration number in a field that is usually labeled "Registration Number," "License Plate Number," or "Current Registration." The title is larger than the registration card and is typically kept at home rather than in your wallet.

If you have recently bought the vehicle, the title may be in the name of the previous owner or a lender. Your registration number will still be on it. If you have not yet received your title after a recent purchase, contact your state DMV — they can tell you the registration number while you wait for the document to arrive.

Use your state DMV website or phone line to look it up

Every state DMV maintains a record of your registration. You can contact them by phone, visit an office in person, or use their online lookup tool if one is available. Have your VIN and driver's license ready — the DMV will use these to confirm your identity and pull up your registration number.

Many state DMV websites now have a self-service lookup portal. You enter your VIN, last name, and sometimes your date of birth, and the system returns your registration number when ready. This is faster than calling or visiting an office. Search "[your state] DMV registration lookup" to find the tool for your state.

Find your VIN if you need it for the DMV lookup

Your VIN is a 17-character code that identifies your specific vehicle. It appears on your title, registration card, and vehicle insurance documents. You can also find it on the dashboard at the base of the windshield on the driver's side, or on the driver's side door jamb. If you are looking up your registration number through the DMV, having your VIN will speed up the process.

Do not confuse your VIN with your registration number. The VIN is permanent and unique to your vehicle. Your registration number changes if you move to a different state or if your state reassigns plate numbers during renewal.

What to do if your registration has expired

An expired registration does not change your registration number — it only means your registration card is no longer valid. You can still find your registration number on the expired card. If you need to renew your registration, the DMV will issue a new card with the same number (unless your state reassigns numbers during renewal, which is rare).

If you have lost your expired card and cannot find your title, the DMV can still look up your number using your VIN. Call your state DMV or visit their website to confirm whether your registration is currently active and what your number is.

Frequently Asked Questions

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

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

Can I look up someone else's registration number?

No. DMV records are private. You can only look up your own registration number using your VIN and driver's license. If you need information about another vehicle for a legal reason, you will need to contact law enforcement or an attorney.

What if my registration number is different on my card and my title?

This should not happen. If the numbers do not match, contact your state DMV when ready. It may indicate an error in your records, or that your registration was recently changed. The DMV can correct the discrepancy.

Do I need my registration number to renew my registration?

No. The DMV looks up your record using your VIN and driver's license. However, having your registration number on hand can speed up the process if you are renewing by phone or mail.
