What is COE?

COE stands for Certificate of Entitlement. It is a licence granted by Singapore’s Land Transport Authority (LTA) that gives the holder the right to own and operate a vehicle on Singapore’s roads for a period of either 5 or 10 years.

Without a valid COE, a vehicle cannot be legally registered or driven in Singapore. When you buy a new car in Singapore, the COE cost is included in the purchase price. When your COE expires, you must either renew it (pay for a new COE) or deregister the vehicle and scrap or export it.

Why Does Singapore Have COE?

Singapore is one of the most densely populated cities in the world, with a land area of just 733 km². Unlike most countries, Singapore uses the COE system to actively manage the total number of vehicles on its roads.

The COE system was introduced in 1990 by LTA as part of the Vehicle Quota System (VQS). The goal is straightforward: by controlling how many new vehicles are registered each year, Singapore keeps traffic congestion manageable and roads functional.

Each month, LTA determines how many new COEs are available based on deregistrations and transport planning targets. This quota is then auctioned through a competitive bidding exercise — and the price you pay is determined entirely by demand.

COE Categories Explained

LTA divides vehicles into five categories, each with its own COE quota and bidding price:

Cat E COEs are the most flexible but typically the most expensive, as they can substitute for any other category. Many buyers of Cat B vehicles end up bidding in Cat E if Cat B prices are lower there, or vice versa.

How the Bidding System Works

LTA conducts COE bidding exercises on the 1st and 3rd Wednesday of every month. Each exercise runs for two days, and the results are published on the LTA website.

The bidding system works as follows:

1. LTA announces the available quota for each category before each exercise.
2. Buyers (or their authorised dealers/brokers) submit sealed bids stating the maximum amount they are willing to pay.
3. At the end of the bidding period, all successful bidders pay the same price — the Quota Premium (QP), which is the lowest successful bid that clears the available quota.
4. Unsuccessful bidders (those who bid below the clearing price) do not get a COE and must try again in the next exercise.

COE and Vehicle Renewal

Every COE has a 10-year lifespan (or 5 years if you chose a shorter term). When it expires, you have three options:

• Renew for 5 years — pay 50% of the current Prevailing Quota Premium (PQP)
• Renew for 10 years — pay 100% of the current PQP
• Deregister the vehicle — scrap it or export it, and claim any applicable PARF rebate

The PQP (Prevailing Quota Premium) is not the same as the latest bid price. It is a 3-month moving average of COE prices for the relevant category. This makes renewal costs more predictable and less volatile than if they tracked the latest bidding result directly.

How COE Affects Your Vehicle Costs

COE is one of the largest costs of owning a vehicle in Singapore. For a Cat A vehicle with a PQP of S19,432, the 10-year renewal cost alone is over S19,000 — before financing costs. This is why financing the COE through a bank loan is extremely common.

The COE system means that Singapore has some of the highest vehicle ownership costs in the world — but also some of the best-maintained road networks and lowest congestion levels among major global cities.
