Q Plates & VINs explained

Q plates

Where a vehicle is assigned a Q or QNI Registration Number by the DVLA then any original vehicle registration number will become invalid and you must not display it again.

A Q or QNI Registration Number is assigned when there are doubts over a vehicle’s age or identity.

A vehicle assigned a Q plate will also need to go through a Basic Individual Vehicle Approval (IVA) scheme.

Note: Owners who are unhappy with the previous treatment of their registration number claim under the previous Rebuilt and Radically altered policies may now reapply under the new August 2025 rules for an age related or original registration number, and there is no time limitation on this. There is a separate process for Q appeals against decisions made under the other registration policies.

Vehicle Identification Number (VIN)

All vehicles registered in the UK must have a unique, stamped-in vehicle identification number (VIN) and registration number. The VIN is usually stamped into the chassis of the vehicle. It may be lost if you restore or modify your vehicle.

If you have a reconstructed classic, kit build or kit converted vehicle, a DVLA generated VIN will usually be allocated by the DVLA.

DVLA issues their own 17 digit replacement VIN to vehicles whose age or identity is in doubt. If this happens, any original vehicle registration number will become invalid and you must not display it again.

Basic IVA

Basic IVA involves a visual inspection and other tests to make sure the vehicle meets the necessary standards. You will not normally need to provide any documentary evidence. Read the guide here.
