Registration numbers are assigned to every vehicle. If you're the registered keeper of a vehicle, you and the person who is about to become the registered keeper can apply to transfer the vehicle's registration number to another vehicle.
The vehicle registration certificate V5C or V5CNI in Northern Ireland will tell you if the registration number is non-transferable. You can't transfer a registration mark if it'll make the vehicle look younger or if the registration number starts with Q or NIQ.
You can apply to retain the vehicle's registration number only if you are the registered keeper, or the person who is about to become the registered keeper, of the vehicle. If the registration number is being transferred to another person's vehicle, both registered keepers must sign the form.
Vehicles must be currently registered in the UK, subject to annual testing (i.e. MOT test or Goods Vehicle Test (GVT)), currently taxed and available for inspection.
If the donor vehicle (i.e. the vehicle you're transferring from) isn't taxed, you can still apply as long as:
The recipient vehicle (i.e. the vehicle you're transferring to) must be taxed.

If the vehicles need to be inspected, the DVLA will contact you to arrange this. Otherwise, your application should be approved within 2 weeks.
The DVLA in Swansea will then send you:
