How to retain your old registration number on a new vehicle in Kerala

Last updated: October 2026

Yes, you can keep your old registration number and put it on a new vehicle in Kerala, through the Retention of Registration Number service on Vahan, on parivahan.gov.in. Retention is for the same owner and for a new, not yet registered vehicle of the same class: a car number goes to a new car, a motorcycle number to a new motorcycle. Apply before you sell or scrap the old vehicle, because once its registration is transferred or cancelled without retention, the number goes with that record. No separate Kerala retention fee could be verified on the official Parivahan fee schedule for this guide: the total shown on your own Vahan retention application is the final amount.

What retention is, and what it is not

Retention parks your number with the registering authority so it can be assigned to your new vehicle at registration, instead of a random new number. The old vehicle is given a different number, with a fresh RC and new plates, before it is sold on or scrapped.

It is not a transfer to another person. A retained number can only move to a new vehicle owned by the same person whose name is on the old RC. You cannot retain a number for a spouse, a buyer, or a company unless that name is the owner on both records.
It is not for a used vehicle. National service guides are consistent that a retained number is assigned only at the first registration of a new vehicle. It cannot be swapped onto a vehicle that is already registered with its own number.
It is not the same as booking a fancy number. Booking a choice number is a separate service with its own reservation tiers and e-auction. See our guides to checking fancy number availability in Kerala and the fancy number plate Kerala price list for those tiers, but do not assume they are the retention fee.

Who can apply: the conditions that matter

Condition	Position
Owner	Same person on the old RC and on the new vehicle invoice
Vehicle class	Same class: car to car, motorcycle to motorcycle. A car number cannot be retained onto a motorcycle, and the other way round
New vehicle	Brand new and not yet permanently registered. Tell the dealer before registration starts, not after a random number has been allotted
Old vehicle	Still registered in your name when you apply. Apply before the sale transfer or the scrapping cancellation is completed
Minimum period you must have held the old number	No Kerala period could be verified on an official page. Other states publish their own, for example one year in Gujarat and three years in some other rules, so do not assume either is the Kerala rule: confirm it at your RTO before planning a sale around it

Keep tax, insurance and PUC current on the old vehicle, and clear pending e-challans where the portal asks. A blocked record will stall retention just as it stalls a transfer.

Fee for retaining a number in Kerala

The central fee schedule on parivahan.gov.in, as last read for this site, carries no separate line that could be verified as a Kerala retention fee. That is why no single retention figure is quoted here.

Item	Position
Separate retention fee on the official fee schedule	No separate Kerala line verified
Amount you actually pay for retention	The total shown on your Vahan retention application before payment
New vehicle registration and road tax	Payable as normal for the new vehicle, on top of any retention charge. Retention does not replace registration or tax
Dealer or agent help, if you use it	A private service charge on top of the government fee, not an RTO fee. Ask for an itemised receipt

Verification gap: parivahan.gov.in and mvd.kerala.gov.in did not respond at research time in October 2026, so this position is based on the fee schedule as last read for this site and the documented Vahan retention flow in national guides, with the live Vahan payment screen treated as final. Other states slabs, such as Gujarat, do not apply in Kerala.

Documents to keep ready

Original RC of the old vehicle
Government ID and address proof of the owner, matching the RC name
Valid insurance certificate and PUC certificate for the old vehicle
Sale invoice or booking papers for the new vehicle, in the same owner name
Financier NOC or loan closure papers, if the old vehicle is or was under hypothecation
For a scrapping case: the facility papers, kept in sequence with the retention approval

Steps: apply for retention on Vahan

Decide before you dispose of the old vehicle. Retention has to be set in motion while the old vehicle is still in your name. Do not complete a sale transfer or a scrapping cancellation first and ask for the number afterwards.
Tell the new vehicle dealer at booking. Say clearly that the new vehicle is to be registered with your retained old number, so the dealer does not file a normal registration that allots a random number.
Open the official portal. Go to parivahan.gov.in, open Online Services, then Vehicle Related Services, and select Kerala and the RTO where the old vehicle is registered.
Start the Retention of Registration Number service. Log in, choose the retention service, and enter the old registration number and the chassis details the portal asks for, then complete the OTP verification.
Fill the service and insurance details for the old vehicle, and check the owner name matches your ID exactly.
Check the fee panel and pay the total shown for your application, and save the acknowledgement, application number and payment receipt.
Attend the RTO if asked, with the original RC and originals of everything uploaded.
Give the retention approval to the dealer. The dealer uses it when filing the new vehicle registration, so the new vehicle is allotted your old number instead of a new one.
Complete the old vehicle side. It is allotted a different number, its RC is re-issued, and its plates are changed, before you hand it to a buyer or a scrapping facility.
Track both applications on Vahan until the new RC shows the retained number and the old record shows its replacement number.

Timing: selling, scrapping, and the order of events

If you are selling the old vehicle, retention comes first, then the transfer happens with the old vehicle carrying its replacement number. Our guide to RC transfer fees and timelines in Kerala covers that transfer stage. If you are scrapping the old vehicle, get the retention approved before the registration is cancelled against a Certificate of Deposit, because a cancelled record leaves no live number to retain: see our guide to vehicle scrapping in Kerala for the scrapping sequence. No fixed Kerala window for using a retained number could be verified, so treat any window on your approval as binding.

After the number moves: update everything else

Plates: the new vehicle needs fresh HSRP plates with the retained number. Do not move the old vehicle physical plates onto it.
Insurance: the new policy must carry the retained number, and the old policy must be endorsed to its replacement number.
FASTag and apps: update the number on FASTag and parking or apartment records for both vehicles.
Digital copies: fetch fresh RC copies for both vehicles on DigiLocker and mParivahan once the records update.

FAQs

Can I retain my old number for a vehicle bought in another persons name?

No. The old RC and the new vehicle must be in the same owner name.

Can I move a car number to a new motorcycle, or a bike number to a car?

No. Retention stays inside the same class: four-wheeler to four-wheeler, two-wheeler to two-wheeler.

I have already sold my old vehicle. Can I still retain its number?

Treat that as closed in most cases: once the transfer completes, the number belongs to that record in the buyers name. If your transfer is filed but not yet approved, ask the RTO immediately whether retention can still be taken up.

What does retention cost in Kerala?

No separate Kerala fee could be verified, so no single figure is quoted here. The total on your Vahan application is what you pay, plus the new vehicle registration and road tax.

Does the old vehicle become illegal to drive after retention?

Not if you finish properly: it gets a replacement number, a re-issued RC, and new plates. Never drive it displaying the retained number after that number is assigned to the new vehicle.

Fees and rules change without notice. Verify all fees and rules on parivahan.gov.in before applying, and treat the fee total and the conditions shown on your own Vahan retention application as the final figure.
