Your car's registration number, more commonly known as the license plate number in the U.S., is found on the metal or plastic plates attached to the front and rear of your vehicle. The official vehicle registration document (often called the "pink slip" or title) and your insurance card also list this number. If the plates are missing from the car, these documents are your primary source.
The most straightforward place to look is on the license plates themselves. By law, they must be securely mounted on the front and rear bumpers. The number is a combination of letters and numbers unique to your vehicle's registration with the state's Department of Motor Vehicles (DMV).
If you can't check the plates directly—perhaps you're filling out a form away from the car—you need your official registration documents. These are typically kept in the vehicle's glove compartment for easy access. The registration card will clearly display the license plate number alongside your Vehicle Identification Number (VIN), name, and address. Your car insurance card, which you should also have in the car, will usually contain the plate number.
The location can sometimes vary slightly depending on the vehicle type. For clarity, here are the common locations:
| Location Type | Specific Spot | Example/Note |
|---|
| On the Vehicle | Front and Rear Bumpers | Standard mounting location for most passenger vehicles. |
| Official Documents | Vehicle Registration Card | Typically found in the glove compartment; the most reliable source. |
| Official Documents | Certificate of Title (Pink Slip) | Kept at home for safekeeping; used for selling the car. |
| Official Documents | Auto Insurance Card | Proof of insurance, often required during traffic stops. |
| Temporary Tag | Rear Windshield | For newly purchased vehicles before permanent plates arrive. |
| Motorcycle | Rear Fender | Usually only one plate is required on the back. |
| Trailer | Rear of the Trailer | Often a smaller, specialized plate. |
If you've just bought a car, you might have a temporary tag taped inside the rear windshield. This temporary registration has a number that serves as your plate number until your permanent plates arrive in the mail. Always ensure your plates are clean, visible, and properly illuminated to avoid citations.
