Assign a number plate | How to register a private plate?
The transferring of a private registration plate from a certificate (V750/V778) to a vehicle is commonly known as 'assignment' or assigning a number plate to a car.
You will need to send the full V5C (log book) for your vehicle to the DVLA. They will then arrange to assign the number plate. You will then receive a replacement V5C back in the post showing the new registration. At this point, you can inform your insurer of the assignment of a private number plate and display the acrylic plates on the vehicle. Any applicable tax and MOT records will be automatically updated to reflect the newly assigned registration.
Checklist Before Assigning a Number Plate To a Car
Before contacting the DVLA about assigning a number plate to a car, some criteria must be met to assign a registration to a vehicle:
- The vehicle must either hold both current MOT and tax, be taxed and MOT expired, or be MOT expired and tax expired less than six months ago. 
- The vehicle must be subject to MOT testing at some time during its life. 
- You can't use a number plate to make a vehicle look newer than it is, e.g. you can't assign a 68 series registration to a 51 registration car. 
- You can't perform a number plate transfer onto a Q-registered vehicle. 
- The car must be registered with the DVLA in the UK 
- It must be able to move under its own power 
- It must have been taxed or had a SORN in place continuously for the past 5 years 
- It must be available for inspection 
The DVLA will check your number plate assignment application and contact you if your vehicle needs an inspection.
How to Assign a Registration Plate to a Vehicle
If the vehicle is registered to you, you can apply online or by post. If it's a used vehicle, you will need to wait for the DVLA to send you a new V5C in your name before you apply to assign the private registration plate.
If your vehicle is brand new, give the dealer your V750 or V778 document and ask them to apply.
If it's registered to someone else and you want the private number to be transferred to them, you can apply online or by post.
If you already have a private number on your vehicle, apply to take it off first. You could lose the right to use the number if you do not.
Assign a Number Plate By Post
You will need to send all of the following documents to the DVLA:
- The completed V750 or V778 - the address is on the form 
- The vehicle’s log book (V5C) or green new keeper’ slip with a completed V62 Application For A Vehicle Registration Certificate V5C’ 
- If you’re assigning the number to someone else’s vehicle, add them as a nominee - complete section 2 of the V750 or V778. 
To tax your vehicle at the same time, include the following:
- A V10 application for the vehicle tax form 
- The right amount of vehicle tax 
After you assign a private number plate by post. You’ll be sent a new log book (V5C).
You must then:
- Put new number plates on the vehicle before you drive it 
- Tell your insurance company your new registration number 
You can keep the original plates - the registration will likely be reassigned to the vehicle should you take off the private number.
You must not sell or get rid of a vehicle until you get the new log book (V5C).
Assigning A Number Plate To A Vehicle That Is Not Yours
If the registration plate is to be assigned to a vehicle that is not registered in your name - for example, the private plate is for a gift - you will need to add them as a nominee and complete section 2 of the V750 or V778.
How Much Does it Cost to Assign a Number Plate?
As the transfer fee is paid upfront when acquiring a certificate, there is no further charge to assign the registration to a vehicle, i.e it's 'free' to apply online or by post.
