Selling a vehicle
If you sell your vehicle, hand over the vehicle registration document to the new owner.
Keep your old number plates, which you can use for a new vehicle.
If you do not buy a new vehicle to replace the old one, hand your plates back to the driver and vehicle licensing office.
If you scrap your vehicle, have the registration document cancelled by the licensing office.
If you deregister a vehicle with interchangeable plates, the office will cancel the registration document and notify your insurance company. You may find that you pay lower premiums as a result.
Report the loss of your plates immediately to the nearest police station or to Suisse ePolice (website available in German, French and Italian), the digital police portal for Switzerland's police forces. You will be sent a police report.
Then report the loss additionally to the driver and vehicle licensing office of the canton where you live (website available in German, French and Italian).
