 In such a situation the licence plates are usually carried over to the new owner, because the change carries an additional cost.Upon purchasing a vehicle from another person, if the vehicle has an EU plate, the new owner must replace it with a license for their address and area, and give the EU plate to their powiat plate mint to free up numbers in the future.If the car has a pre-May 1, 2006 plate, the owner is free to do whatever they wish with it, as long as it is legal under Polish law.
