The service we received from Yellowhite was responsive, informative and very professional. Dylan was especially personable. This company deserves 5 *
If you're applying by post to move a private plate to another vehicle, or take it off and keep it for later, you'll use DVLA form V317. This page explains what it's for, who needs it, what to send, and what happens next.
DVLA-aligned guidance (kept up to date)
This guide is kept in line with DVLA's published process for taking a private number off a vehicle, assigning it, and using postal form V317 where needed. Last checked: 22/12/2025.
What is the V317 form?
The V317 form is the DVLA's official application to either:
- Option A (Transfer): take the registration number off one vehicle and put it straight onto another vehicle.
- Option B (Retention): take the number off a vehicle and keep it on a retention document for up to 10 years (so you can assign it later).
It's one form with two options. You just tick the one you need. The DVLA also offers online services for many transfers/retentions (and that's usually faster), but V317 is still essential, especially for cases that can't be completed online.
When do you need a V317?
Here are the most common scenarios:
| Situation / goal | Use V317? | Online usually possible? |
|---|---|---|
| Selling your car but keeping the private plate | Yes | Yes |
| Moving your plate from old car to new car | Yes | Yes |
| Transferring to someone else's vehicle | Yes | Sometimes |
| You can't use DVLA online services | Yes | No |
Some vehicles are just not eligible for the DVLA's online services, and in this case the V317 reg transfer form is your best bet.
Where can I get a V317 form?
You can get the V317 form directly from DVLA via the GOV.UK site: Application to transfer or retain a vehicle registration number (V317).
How to complete V317 (simple step-by-step)
- Get the latest V317 form: Download the current DVLA V317 form. Using the latest version matters because DVLA occasionally updates wording and checklists.
- Choose transfer or retention: V317 covers two routes — Option A (transfer) and Option B (retention). Tick the option that matches what you're doing, then complete only the relevant sections.
- Fill in the vehicle and keeper details carefully: Enter the registration number(s), VIN/chassis details (where requested), and keeper information exactly as shown on the V5C logbook(s). If anything doesn't match DVLA's records, it can delay processing.
- Include the required documents and the £80 fee: Enclose the original documents DVLA asks for (usually the V5C logbook for each vehicle). Include the £80 fee using the payment method stated on the V317. If you're taxing the vehicle at the same time by post, include the extra items DVLA requests.
- Post it to DVLA and wait for confirmation: Post your completed V317 application to: DVLA Personalised Registrations, Swansea, SA99 1DS. DVLA will confirm the outcome and issue updated documents (like a new V5C). Don't fit new plates or drive with the new registration until DVLA confirms the change.
Can you use the DVLA V317 process online?
Yes! In many cases, it's quicker and easier to use the DVLA's online transfer or retention service. You can complete the transfer or retention instantly if:
- Both vehicles are registered in your name
- You have the latest, updated and correct V5C details
- The vehicle has valid MOT and is taxed
If any of the above doesn't apply, you'll need to use the paper V317 form. Additionally, not all vehicles are eligible for the DVLA's online services.
What happens after you submit the form?
Once DVLA approves your V317 application, they update the vehicle(s) on the DVLA database and issue the paperwork that proves the change has happened. What you receive depends on whether you chose Option A (Transfer) or Option B (Retention).
If you transfer the reg from vehicle to vehicle (Option A):
- DVLA will assign the private number to the recipient vehicle (once processed).
- DVLA will update the donor vehicle's registration (it'll be given a replacement registration / revert as applicable).
- DVLA will issue updated V5C log books for the vehicle(s) affected.
- You should update your insurance with the new registration number before driving.
- You should fit the new plates only after DVLA confirms the assignment/removal.
MOT and tax records generally update automatically after DVLA updates the vehicle record.
If you retain the plate on a certificate (Option B):
- DVLA will remove the private number from the vehicle and (in most cases) reassign the vehicle's original registration number automatically.
- DVLA will send you a V778 Retention Document (this is the proof you still hold the right to the registration).
- DVLA will send an updated V5C log book for the vehicle showing its new (restored) registration.
- You should update your insurance with the vehicle's new registration number before driving.
- You should swap the physical plates back to match the registration DVLA has confirmed.
MOT and tax records generally update automatically after DVLA updates the vehicle record.

V317 Fee: How much does it cost?
Flat fee: £80. This covers either a transfer or a retention. And there's no extra fee to reassign the plate later or extend the certification (as long as it's within its 10-year validity on the V778).
