DVLA told us: "If someone chooses to remove a personalised registration number from a vehicle it will revert to the registration number that was on the vehicle before the personalised number was on the vehicle. So if a vehicle had a personalised number put onto it when it was already displaying a different personalised number – this is the number it will revert to. If the keeper wanted the vehicle to display an age related registration number (not a personalised one) they would need to send an application to do so to us with a letter explaining what has happened. However if they want to keep this number to put onto a vehicle of their choice then they can apply to retain the number and pay the £80 fee. I should advise that where paper applications are posted to DVLA there will be delays in processing them because we have a reduced number of staff in our building to comply with social distancing requirements. Further advice on coronavirus (including the applications we are currently processing) is published on www.gov.uk/guidance/dvla-coronavirus-covid-19-upda...t;
