To retain a number plate is to ask the Driver and Vehicle Licensing Agency (DVLA) to take a registration number off a vehicle and hold it in your name, so you can assign it to another vehicle later. The DVLA records the entitlement on a V778 retention document, and the car you took it from goes back to its original or a replacement registration.
Part of Plate Transfer & Retention. Start with the main guide: How to Remove a Private Plate from a Car
Updated October 2026 · Independent information, not legal advice
Retention is what stops a number leaving with a car you are selling, scrapping or replacing. It is a paperwork job with a clear order of steps, a few traps around expiry dates and insurance, and one rule above all: apply before the vehicle leaves your hands.
What Does It Mean To Retain A Number Plate?
To retain a private plate means the DVLA records that you, not the vehicle, hold the right to a registration number. The number is detached from the donor vehicle and kept on file for you.
- The right is recorded on a V778 retention document.
- The number cannot be displayed on any vehicle while it is retained.
- You can assign it to a vehicle you keep, or sell it, within the DVLA's rules.
- You remain the registered keeper of the vehicle until it is sold.
Retention versus ownership
A registration is an entitlement the DVLA records, not property in the usual sense. That is why movement of a number is always a DVLA record change, never a handover of plates.
Does retaining change the car?
The vehicle stays the same vehicle, with the same tax, MOT history and keeper. Only its registration number changes in the DVLA's records.
Why Would You Retain A Registration?
You retain a number whenever the car and the number need to part company. The common triggers are straightforward.
- Selling or part-exchanging the car while keeping the plate.
- Scrapping or writing off the vehicle.
- Buying a new vehicle and wanting the plate on it later.
- Holding a valuable number as an investment until you decide what to do.
- Putting a private number aside after buying it from the DVLA or an auction.
Is it worth retaining a low-value number?
That is a personal judgement. The DVLA's fee and the cost of new plates set a floor, and a number you will never use is not worth keeping on file.
Selling A Car But Wanting To Keep The Private Number Plate
If you are selling a car but want to keep a private number plate, retain the number before the sale completes. Once the vehicle changes keeper with the number still on it, the registration goes with the car as far as the DVLA's records are concerned.
- Apply to retain the number while you still hold the car.
- Wait for the DVLA's confirmation and your V778.
- Have plates made for the car's original or replacement number.
- Complete the sale and hand over the correct V5C.
- Check the car is eligible before you advertise the plate separately.
- Keep the V778 safe until the number is assigned or sold.
Tell the buyer in good time
A buyer who expects the private plate to be included needs to know before the price is agreed. Put the registration the car will carry in the advert and the receipt.
Who Can Retain A Number?
The registered keeper named on the V5C is normally the person who applies. For some vehicles, such as a leased or financed car, the keeper may need the finance firm's agreement, as covered in private number plates on finance.
Companies and fleets
A business keeper applies through someone authorised to act for it, and the entitlement then belongs to the business.
Executors and family
If the keeper has died, the executor generally deals with the DVLA. The DVLA's GOV.UK guidance explains the paperwork.
Joint keepers
The V5C names one registered keeper, so decide who holds the entitlement before you apply.
What Conditions Must The Vehicle Meet?
The DVLA sets conditions on the vehicle a number is retained from, and they can change, so confirm them on GOV.UK. They usually cover registration status, tax, MOT where one is required and whether the vehicle is eligible.
- The vehicle must be registered with the DVLA in the UK.
- It must normally be taxed or meet the DVLA's alternative conditions.
- Where an MOT is required, it usually needs to be valid.
- Vehicles recorded as scrapped or exported are not usually eligible.
Why the MOT and tax matter
The DVLA checks vehicle tax and MOT records through its systems. Read taxing a car without an MOT to see how those checks work.
What Do You Need Before Applying?
Gather the paperwork first. The commonest cause of a delayed retention is a missing or out-of-date document.
- The current V5C for the vehicle.
- The V750 certificate of entitlement or an existing V778, if you hold one.
- The vehicle's registration and the keeper's details.
- Proof of identity, when the service or a supplier asks for it.
What if you cannot find the V5C?
Apply to the DVLA for a replacement first. Taxing a car without a V5C explains what is and is not possible while you wait.
Checking names and addresses
A small difference between the V5C and the application can cause a rejection, so match them exactly.
How To Retain A Vehicle Registration Online
The online route on GOV.UK is the quickest option for most eligible vehicles. The service asks for details from the V5C and for confirmation that you want to retain the number.
- Go to the DVLA's transfer or retain service on GOV.UK.
- Enter the registration and the V5C details when asked.
- Choose to retain the number instead of assigning it.
- Check the details and pay the fee displayed by the service.
- Keep the confirmation, and wait for the V778 and the new V5C.
When online is not available
If the service rejects the vehicle, use the paper route or contact the DVLA. How to contact the DVLA lists the channels.
How To Retain A Car Registration By Post
The paper route uses form V317. You complete it, enclose the V5C and any other certificates it asks for, and post it to the address on the form.
- Download the current form from GOV.UK.
- Match names and addresses exactly to the V5C.
- Send by a tracked service and keep a copy.
Is the paper route slower?
Usually, because it depends on the post and manual handling. Do not plan a sale around it.
Sending documents safely
Photograph each page before posting, and use tracked delivery.
What Do The V778 And V750 Mean?
A V750 certificate of entitlement is issued when a number is bought from the DVLA. A V778 retention document is issued when a number is taken off a vehicle and retained. Each proves your right to assign the number, and the DVLA treats them as the key paperwork.
What does a V778 show?
It shows the registration number, the holder's name and an expiry date. Check these details on arrival.
Is a reg certificate the same as a V5C?
A reg certificate is a casual way of saying V5C, the registration certificate showing the vehicle's registered keeper. It is not the same as a V778.
Which document proves what?
The V750 proves entitlement on a new purchase, the V778 proves entitlement after retention, and the V5C proves the vehicle's registered keeper.
What Happens To The Car When You Retain Its Number?
The vehicle reverts to the original registration number, or to a replacement number if the original is not available. The DVLA records this and sends a new V5C.
The replacement number
If a replacement is issued, it is usually an age-appropriate number chosen by the DVLA. Check the V5C and have the plates made to match.
Plates on the car
Once the DVLA confirms the change, order new plates for the car's new number from a registered number plate supplier.
How Long Does Retention Last?
The V778 has an expiry date, and the entitlement can be renewed under the DVLA's rules. The period and renewal procedure are on GOV.UK, and they may change, so read the current guidance rather than relying on any earlier rule of thumb.
- Note the date when the V778 arrives.
- Renew before it expires, not after.
- Do not assume a lapsed number can always be recovered.
Why a calendar reminder helps
A retained number is easy to forget when it is not on any car. A reminder a few months before expiry avoids the problem.
Can You Retain A Number From A Car On SORN?
Often yes, subject to the DVLA's conditions, so check GOV.UK for the current rule. A car on SORN must be kept on private land, so avoid driving it to fit plates. How to SORN your car explains the status.
Do You Need To Tell Your Insurer?
Yes. Insurance is recorded against the registration, so tell the insurer when the car's number changes because of retention. A mismatch between the plates and the Motor Insurance Database can make the vehicle look uninsured.
Checking after the change
Once your insurer has updated the record, run a Motor Insurance Database check. The free number plate check does not show insurance.
When to ring them
Before the plates change, not after. Ask them to note both the old and the new registration.
What Happens To Tax And The MOT?
Vehicle tax and the MOT belong to the vehicle, not to the number, so retaining a number does not move them. The DVLA updates its record to the new registration, and you should confirm the status afterwards with the MOT check.
Tax refunds
A refund relates to selling, scrapping or SORN, not retention. See car tax refund.
Checking the record afterwards
The vehicle tax status lookup should show the same tax end date under the new registration.
What If The Car Is Scrapped Or Written Off First?
Contact the DVLA before the vehicle is disposed of. If the car is scrapped or written off before retention, the options depend on its status in the DVLA's records. Tell your insurer you want to keep the number.
- Do not let the vehicle go before the retention is confirmed.
- Ask the insurer or the scrap yard to wait.
- Keep the V5C and all paperwork.
Retaining A Number When You Buy A New Car
The sequence is the same: retain from the old car, then assign to the new car once it is registered in your name. You can buy first and move the number second, as long as you keep the retention valid.
Part exchange
If a dealer takes the old car, tell them that the plate stays with you and get that written on the invoice.
Buying a car that already has a private plate
Check the V5C and ask the seller whether the number is included, because retained numbers are removed before the sale.
Northern Ireland, Imports And Special Cases
Northern Ireland registration stays with the DVLA, so retention follows the same rules, while tests are run by the Driver and Vehicle Agency (DVA). MOT in Northern Ireland explains the testing difference.
Imported vehicles
An imported car registered in the UK is treated like any other, but its original number may need checking on the V5C.
Classic and motorcycle plates
Classics often carry dateless-style numbers that reveal their age. See dateless number plates.
Common Mistakes With Retention
Most problems are caused by timing and by assuming plates can simply be swapped.
- Selling the car before applying.
- Changing plates before the DVLA confirms.
- Letting the V778 expire.
- Forgetting to tell the insurer.
- Using a plate supplier that is not registered.
- Assuming tax and MOT move with the number.
The most expensive one
If a car with a retained number has already been sold, recovering it depends on the buyer. Retain first.
Myths About Holding A Number
A retained plate can be displayed. It cannot until it is assigned. Retention is permanent. It has an expiry date. Anyone can retain a number from any car. You must be the entitled keeper and the vehicle must meet the conditions.
Is it only for expensive plates?
No. Any private registration can be retained.
Myth: dealers can keep it for you
A dealer can handle paperwork, but the entitlement is recorded in your name.
Which Route Fits: Retain, Assign, Transfer Or Sell?
| Route | What it does | Document | Typical user |
|---|---|---|---|
| Retain | Holds the number off any vehicle | V778 | Seller keeping the plate |
| Assign | Puts it on a vehicle you keep | New V5C | New car owner |
| Transfer between vehicles | Moves it in one go | Updated V5C | Someone changing cars |
| Sell | Passes the entitlement on | Paperwork from the sale | Plate owner cashing in |
After Retention: What Next?
You can assign the number to another vehicle, keep it on retention while the V778 is valid, or sell it. How to put a private number plate on a car covers the assignment and plate-fitting steps, and how to remove a private plate covers the removal route in detail.

Selling your licence plate and valuing a registration explain the options.
Retain Number Plate: The Short Version
To retain number plate entitlement, apply to the DVLA before the car leaves your possession, wait for the V778, then fit plates for the car's original or replacement number.
- Apply while you still hold the car.
- Do not move any plates before confirmation.
- Tell the insurer.
- Diarise the V778 expiry date.
A sensible order of work
Retain, confirm, re-plate, insure, then sell.
What The DVLA Will Not Allow
The DVLA will not allow a number to make a vehicle look newer than it is, and it does not issue combinations it regards as offensive or confusing. These limits apply to the recipient vehicle too.
Age-related numbers
A vehicle first registered in one year cannot take a plate that implies a later year. The number plate year chart explains the identifiers.
Format and fit
The registration must also suit the legal plate format, so check how the legal rules work.
What Happens If You Never Assign The Number?
If you never assign a retained number, the V778 eventually expires and, unless renewed under the DVLA's rules, the entitlement may be lost. Choose between assigning, renewing or selling before the date.
Selling instead of letting it lapse
A number you will not use can be sold; how to sell a licence plate covers the options.
Retaining From A Motorbike, Van Or Trailer Tow Car
Motorbikes, vans and commercial vehicles are retained in the same way. A motorbike normally needs only a rear plate, and a trailer shows the tow car's registration, so a plate change affects trailer plates too.
Checking motorbike plate rules
Read motorbike number plate rules before ordering.
How Long Does The Whole Retention Process Take?
The time varies, and the DVLA's guidance on GOV.UK is the only reliable source. Plan the sale or the next purchase around the V778 arriving, not around a guess.
- Online applications are generally faster than postal ones.
- Time is also needed for the plate supplier.
- The new V5C may arrive separately.
Can You Retain A Number From Someone Else's Car?
Only the entitled keeper can retain a number, so you cannot retain from a car you do not keep. If you are buying a car and the number matters, agree with the seller who applies and when, and keep the agreement in writing.
Agreeing it in writing
A short signed note saves arguments.
A Worked Example: Selling A Car With A Private Plate
Imagine you keep a car with a private number and agree to sell it on a Saturday. On the Monday before, you apply online to retain the number, and the DVLA confirms. The V778 arrives in your name, the car reverts to its original number, and a new V5C is issued. You order plates for that original number from a registered supplier, fit them and tell your insurer.
What the buyer receives
The buyer gets a car showing its original registration, the new V5C or the seller's section to complete, and a receipt naming that registration.
What you keep
You keep the V778, which lets you assign the number to a replacement car when you are ready. Nothing else follows the number, so the new car needs its own tax, MOT and insurance.
Why timing wins
Had the sale happened first, the number would have gone with the car. Order of events is everything in retention, and a cheap delay beats an irreversible mistake.
How Is Retention Different From Simply Transferring A Vehicle?
Retention concerns a registration number; transferring a vehicle to a new keeper concerns the car itself and the V5C. A sale usually involves both: the number is retained and the car changes keeper under its original number.
Where the two meet
The seller's V5C section, the buyer's new keeper details and the DVLA notification all happen after the number has been dealt with.
What to read next
For tax cancellation and refunds after a sale, read does road tax transfer.
What To Do If Something Goes Wrong
If your application is rejected, read the reason and fix the cause. If the V778 or V5C does not arrive, contact the DVLA. If the car has been sold with the number on it, speak to the buyer and the DVLA promptly.
Keep evidence
Keep copies of every application and email. They help if the DVLA needs to investigate.
If the buyer has already taken the car
Contact the DVLA and keep all documents; do not try to retrieve plates yourself.

Frequently Asked Questions
How do I retain a private plate?
Apply to the DVLA to take the number off the vehicle and place it on retention. You can use the online service on GOV.UK or form V317 by post. The DVLA issues a V778 retention document and a new V5C for the car. Only change the physical plates once the DVLA has confirmed the change.
Can I retain car registration details if I am selling the car?
Yes, and you should do so before the sale completes. Once the car has a new keeper with the number still on it, the registration generally goes with the vehicle. Retain first, fit plates for the original or replacement number, then sell the car with the right V5C.
What is a V778 retention document?
A V778 is the DVLA certificate that proves you hold the right to a registration that is not on a vehicle. It shows the number, the holder and an expiry date. You need it to assign the number to a vehicle later, so store it safely and note the expiry.
How long can I retain a number plate?
The V778 carries an expiry date and the DVLA allows renewal under its rules. The exact period and renewal route are on GOV.UK and can change, so check the current guidance. Renew before the date passes because recovering a lapsed number may be difficult or impossible.
Is a reg certificate the same as a V778?
No. A reg certificate is a casual name for the V5C, which records the vehicle and its registered keeper. A V778 is a separate document issued when a number is retained. A V750 is issued when a number is bought from the DVLA.
Can I retain a vehicle registration from a car on finance?
You may need the finance company's agreement, because it may have rights over the vehicle and its registration. Check the agreement and speak to the lender before you apply. The DVLA still records the registered keeper, but the lender's consent can be essential.
Can I remove reg plate details from a car without retaining the number?
You can ask the DVLA to take a private number off a car and assign it straight to another vehicle, which avoids a separate retention step. Either way the DVLA must record the change before you swap the physical plates. Never move plates between cars without that confirmation.
Do I have to pay to retain a number plate?
The DVLA charges a fee, and plate suppliers and brokers charge their own, but amounts change so none is quoted here. Check the current DVLA fee on GOV.UK, ask any supplier for a written quote, and compare it with doing the paperwork yourself.
What happens to the car after I retain its private number?
It returns to its original registration number, or the DVLA gives it a replacement if the original is unavailable. A new V5C is issued, and you should order plates for the new number from a registered supplier and tell the insurer.
Does retaining a plate affect my MOT and tax?
No, they stay with the vehicle. The DVLA updates its record to the new registration, so check afterwards that tax and the MOT history show correctly under the car's current number. Contact the DVLA or DVSA if they do not.
Can I retain a number plate after the car has been scrapped?
It depends on the car's status in the DVLA's records and on the paperwork you still hold, so speak to the DVLA as soon as possible. Do not let the vehicle go without confirming how the number will be handled, and tell your insurer if a claim is involved.
Who do I contact if my retention application goes wrong?
Use the DVLA's contact options on GOV.UK. Keep copies of what you submitted, the V5C details and any reference numbers. If a broker or supplier is involved, contact them as well, and for Northern Ireland tests contact the DVA.
What should I do when selling car but want to keep private number plate?
If you are selling car but want to keep private number plate registration, retain it with the DVLA before the car changes hands. Once the number is on a V778 retention document, the car can be sold under its original or a replacement registration. Check the current steps on GOV.UK.
