Retention of registration number
Retention of registration number is the LTA process that lets an owner keep a vehicle's registration number to transfer onto another car.
What it means
Every car in Singapore is registered with a unique number, and normally that number stays with the vehicle. When a car is de-registered or sold, the number would usually be retired or stay attached to the vehicle. Retention of registration number is the LTA process that breaks that link: an owner applies to keep the number, pays the applicable fee, and the number is held for them. Once retained, the number can later be assigned to another car the owner registers, subject to LTA's rules on eligibility and time limits. Owners often do this when a number has personal meaning, such as a memorable combination or one tied to a family vehicle. The retained number is held under the owner's name, not sold openly, and transferring it onto a new car is done through LTA's channels when the new vehicle is registered.
Why it matters in Singapore
Registration numbers carry sentimental and sometimes practical value here, and a number an owner has used for years can feel like part of the car's identity. Without the retention process, changing cars would mean losing the number for good. Understanding that retention exists, that it has a fee, and that the retained number has rules around how long it can be held and how it is reassigned, helps an owner plan a car change without an unwanted surprise at the registration counter.
What it means for car owners
If your current number matters to you, look into retention before you de-register or sell the car, since the timing and paperwork need to line up with LTA's rules. Factor the retention fee into the cost of changing cars. The number itself is separate from the condition of the vehicle, so whether you keep it or not, a well-maintained car with sound paint and bodywork still holds its value better when the time comes to sell.
