24. Licence plate

A licence plate, also called a registration plate or number plate, is a plate displaying a unique registration identifier assigned to a vehicle by the competent registration authority. It allows the vehicle to be identified for purposes such as registration, traffic enforcement, taxation, insurance and parking control.

The appearance, format, placement and number of plates required vary between countries and vehicle categories. Drivers must ensure that required licence plates are correctly fitted, clearly visible and legible and must follow the local rules when a plate is lost, stolen, damaged or replaced.

What is a licence plate?

A licence plate is a plate displaying the registration identifier assigned to a vehicle. It allows authorities and other authorised systems to identify the vehicle's registration.

Is a licence plate the same as a registration plate?

Yes. Licence plate, registration plate and number plate are different terms commonly used for the plate displaying a vehicle's official registration number.

Does every vehicle need a licence plate?

Most motor vehicles used on public roads must display one or more registration plates, but requirements differ for motorcycles, trailers, agricultural vehicles and other special vehicle categories.

Do vehicles need both front and rear licence plates?

This depends on the country and vehicle type. Cars commonly require front and rear plates, while motorcycles and certain other vehicles may require only a rear plate.

Must a licence plate remain visible?

Yes. A required registration plate must normally remain clearly visible and readable. It should not be hidden by luggage, dirt, accessories or other objects.

Can you modify a licence plate?

Generally no. Changing the characters, colours, dimensions or appearance of an official plate may make it invalid or illegal. Plates and authorised reproductions must comply with local specifications.

What should you do if a licence plate is lost or stolen?

Follow the local reporting and replacement procedure. Many countries require the loss or theft to be reported to the police or vehicle-registration authority before a replacement plate can be issued.

Can you drive with a damaged licence plate?

A plate must remain legible and compliant with local requirements. If damage prevents it from being read or makes it invalid, it should be replaced according to the local registration procedure.

Can a licence plate be personalised?

Some countries allow motorists to request a personalised registration combination. The available characters, formats and prohibited combinations are determined by the registration authority.

Does a licence plate stay with the vehicle when it is sold?

This varies between countries. In some systems the plate remains with the vehicle, while in others it remains associated with the registered holder and may be retained or returned when the vehicle is sold.
