Massachusetts License Plate Lookup

All vehicles in Massachusetts must be registered with the Registry of Motor Vehicles (RMV) and have a legal title. You have 30 days to register a new vehicle. It’s a legal requirement for all motor vehicles to display two license plates: one at the front and one at the rear. The rear license plate must also have a validity sticker.

Back in Time

Massachusetts was the first state in the U.S. to issue license plates. The first license plate was issued in 1903 and was made of iron covered in porcelain enamel. The plate was simply numbered “1” and was issued to Frederick Tudor. This historic plate is still in existence today and is preserved by the Massachusetts Registry of Motor Vehicles. The introduction of license plates marked the beginning of standardized vehicle registration, which has since become a common practice across the country.

Where is the Massachusetts Plate Number?

Typically, you can find your plate number by checking the license plate attached to your car. However, if you need to look up your car’s license plate number when you’re away from your vehicle, it can also be found on the car’s registration certificate.
