What Is a Thai Vehicle Registration Book? How to Read It Before Buying or Selling a Vehicle

A Thai vehicle registration book is issued when a vehicle is registered. It records the vehicle type, the registered owner and the years for which road tax has been paid. If you are buying or selling a used vehicle, learning to read the book can reveal details that photos and a test drive cannot. You can browse vehicle listings on Talata and contact a seller to ask about the book before arranging to see the vehicle.

What Is a Thai Vehicle Registration Book?

For vehicles registered under the Motor Vehicle Act B.E. 2522, the official document is called a vehicle registration manual (ใบคู่มือจดทะเบียนรถ). It records the vehicle’s details, the names of its registered owner and possessor, and its tax and transfer history.

In everyday Thai, people may call it a registration book (เล่มทะเบียนรถ), a vehicle book (เล่มรถ), or a vehicle registration manual (สมุดคู่มือจดทะเบียนรถ). They are referring to the same book.

Holding the book does not, by itself, establish that a person owns the vehicle. It is a registration record maintained by the Department of Land Transport. Check whose name appears in it.

Vehicle Registration Manual and Registration Certificate: Different Laws

Different groups of vehicles are registered under different laws, so the documents they receive have different official names.

Vehicles registered under the Motor Vehicle Act B.E. 2522 receive a vehicle registration manual. This group includes passenger cars, private pickup trucks, private vans and motorcycles. Vehicles used for commercial transport, such as large trucks, buses, trailers and semi-trailers, are registered under the Land Transport Act B.E. 2522 and receive a document called a vehicle registration certificate (หนังสือแสดงการจดทะเบียนรถ).

When buying or selling an ordinary private vehicle, you would generally expect to see a vehicle registration manual. If the seller presents a document headed “vehicle registration certificate,” the vehicle may be registered under the transport system rather than as the private vehicle you expected.

What Information Does the Registration Book Contain?

The book records the vehicle’s details, its registered owner and possessor, tax history, and changes made to its registration. Reading each section helps you identify which details to compare with the vehicle itself.

The registration details include the licence plate number, the vehicle category identified by its รย. code, chassis and engine numbers, make, model, model year, colour, engine capacity, fuel type and vehicle weight. Compare these details with the vehicle.

The owner and possessor section identifies the person or organisation recorded as the owner and the person recorded as possessing the vehicle. They are not always the same.

The tax section shows the years for which tax has been recorded. If its spaces are full, Section 19 of the Department of Land Transport’s B.E. 2562 regulation on vehicle registration and tax provides for a fee and a new registration manual to be issued. The fee for the new book is 100 baht. A newly issued book for this reason does not, on its own, indicate a problem with the vehicle.

The official record section contains changes such as a change of colour or engine, a move to another registration area, and previous ownership transfers.

Some websites give fixed page numbers for these records. The regulation cited above does not specify a printed layout or page numbers, so look for the section headings in the book itself. Page positions may differ between versions.

What Is the Difference Between the Registered Owner and the Possessor?

The registered owner and possessor can be different, particularly when a vehicle is still being financed. Check both entries before agreeing to buy or sell.

The registered owner is the person or organisation recorded as owning the vehicle, while the possessor is the person recorded as using it. Both entries are often the same for a vehicle purchased outright. For a financed vehicle, the owner entry may show the finance company or bank, while the possessor entry shows the hire purchaser. The owner entry changes after the account is settled and the transfer is completed.

A person who is still paying off a vehicle cannot independently transfer ownership to someone else, even if they have always driven it. Discovering this after agreeing on a price can delay the sale while the finance account is settled and the book is returned.

How Can You Check Transfer and Tax History?

Look at the recorded changes of ownership to see how many times the vehicle has changed hands. Several transfers within a short period do not automatically mean the vehicle is in poor condition, but they are worth asking the seller about.

For tax history, check which years have entries and which do not. A long gap may suggest that the vehicle was left unused for some time. Ask about the condition of its engine and tyres as well.

What Do the Different Registration Book Colours Mean?

People commonly associate different book cover colours with different groups of vehicles. To identify the registered vehicle category, check the รย. code inside the book.

The Department of Land Transport’s B.E. 2562 regulation on vehicle registration and tax does not specify registration manual cover colours or prescribe a separate printed colour for each category. Section 10 identifies 17 vehicle categories by รย. code. Examples include รย.1 for private passenger vehicles with no more than seven seats, รย.3 for private goods vehicles and รย.12 for motorcycles.

The same applies to the public guide to obtaining a replacement registration manual and to the Department of Land Transport’s vehicle ownership transfer page: neither sets a rule for book cover colours.

Common descriptions of book colours therefore reflect reported practice rather than a rule established by the regulation cited here. According to the sources consulted, blue or light blue books are associated with private passenger cars, green books with motorcycles, and pink books with trucks.

The more reliable way to identify the category is to read the รย. code and vehicle type recorded in the book. Motorcycles are recorded as รย.12, while public-service motorcycles are รย.17.

Why Does the Registration Book Matter Legally?

Transfers, moves to a different registration area, colour changes and changes to a vehicle’s registered details have different legal requirements and deadlines.

Under Section 17 of the Motor Vehicle Act B.E. 2522, both the transferor and transferee must notify the registrar within 15 days of a transfer. Section 16 provides a 15-day period for notifying a move to another registration area, which matters when you transfer a car registered in another province. Under Section 13, a colour change must be reported within 7 days. Section 21 of the regulation also states that the date on a painting receipt may be used as the date of the colour change.

A change to the vehicle or one of its parts that makes it differ from its registered details, such as an engine replacement, falls under Section 14. The vehicle must be presented for inspection by the registrar before use. The section does not set a specific number of days for doing so, unlike the 7-day period stated for a colour change.

Section 60 provides a fine of no more than 2,000 baht for failure to comply with these duties. An official fine schedule also states that the fine should generally be no less than 200 baht.

Buyers and sellers should agree in advance who will go to the transport office and when. The 15-day notification duty applies to both parties.

Can a Copy Replace the Original Registration Book?

A copy of the relevant pages can help you check a vehicle’s details and support certain applications, but it cannot replace the original book for an ownership transfer.

The Department of Land Transport’s public guide requires the original vehicle registration manual as supporting evidence, except where it has been lost. A transaction that changes an entry in the book therefore normally requires the original.

You can use a copy to review details before meeting the seller. Before transferring the vehicle, ask to see the original and compare its entries with the vehicle.

If a seller repeatedly provides only a copy and avoids showing the original, ask why before paying a deposit. The book could still be with a finance company or another person.

What Should You Do If the Registration Book Is Lost?

If the book is lost, apply for a replacement vehicle registration manual at a transport office. According to the Department of Land Transport’s public guide, the process includes receiving the application, checking the documents, recording the circumstances of the loss, collecting the fee, issuing the replacement and updating the registration record. The guide lists 60 minutes of processing time within one working day.

The guide lists the registered owner’s original ID card, the original registration manual except in cases of loss, a company registration certificate if the vehicle belongs to a legal entity, and a power of attorney with a copy of the authorised representative’s ID if the owner does not apply in person.

The fees are 5 baht for the application and 50 baht for the replacement registration manual. If a replacement annual tax disc is requested at the same time, another 20 baht applies. These figures follow the fees and tariffs schedule published by the Department of Land Transport under the Motor Vehicle Act B.E. 2522.

Whether a police report is required needs particular care. The public guide does not list one among its required documents. Section 31(4) of the B.E. 2562 regulation mentions either evidence of a police report about a lost registration manual or a statement from the owner or authorised representative. That provision appears in the section on moving a vehicle, so practice may differ between offices.

Before visiting a transport office, call the office where you plan to apply to confirm the documents it requires, so that you do not have to return with extra paperwork. If what you have lost is the metal number plate rather than the book, the process is different; see our guide to a lost license plate.

What Should You Check Before Buying or Selling a Used Vehicle?

Use the registration book to check both the vehicle’s details and the people involved in the transfer. Even a vehicle in good condition can be difficult to buy or sell if its paperwork is incomplete.

Most used-vehicle listings describe the vehicle itself in reasonable detail: make, model, year, fuel type, engine capacity, mileage, colour, transmission and condition. Three things are not part of the listing fields, though — the registered owner’s name, the finance status and the number of previous transfers. Ask to see the book for those.

Start by narrowing down vehicles using their listing information. Ask the seller for images of the relevant book entries before arranging a meeting, then inspect the original book and vehicle in person. The full order of steps, from setting a budget to receiving the book, is covered in the used car buying process.

For Buyers: Compare the Book with the Vehicle and Seller’s ID

Compare the chassis and engine numbers in the book with those stamped on the vehicle. Every digit should match.

Compare the name in the possessor entry with the ID card of the person selling the vehicle. If they differ, ask for a power of attorney and clarify who the registered person is.

Check whether the registered owner is an individual or a finance company. If it is a finance company, ask whether the account has been settled and when the book will be available.

Review the number of recorded transfers and the tax history against what the seller has told you about the vehicle.

Check official records of colour or engine changes. If the vehicle’s colour differs from the book, ask whether the change has been reported.

For Sellers: Prepare the Book for the Transfer

The documents required for an ownership transfer are the vehicle registration manual, a copy of the ID card, the car sale contract and receipt, a transfer application signed by both parties, and a power of attorney if either party will not attend in person. The registration transfer fee is 100 baht. Prepare the documents before visiting the transport office. If the vehicle was financed, settle the account and obtain the book from the finance company before the transfer appointment.

A floating transfer means signing transfer documents without completing the registration change at the transport office. Until that change is recorded, the seller’s name remains in the register, which may cause problems if issues arise involving the vehicle. Where possible, both parties should complete the process together within the 15-day period under Section 17.

Before agreeing to a sale, compare the available vehicles, read the listing details and inspect the original documents before paying. Once the vehicle and documents match, discuss the next steps with the seller.

Frequently Asked Questions

Can I Buy a Vehicle If the Name in the Book Differs from the Seller’s?

It may be possible if the seller has a power of attorney from the registered owner and all required documents. Check the arrangement carefully. The vehicle may be offered through an intermediary, or transfer documents may have been signed without the change being registered. If you cannot contact the person named as owner in the book, consider pausing the purchase.

Is It Risky If a Used-Vehicle Seller Provides Only a Copy of the Book?

Yes. The Department of Land Transport’s public guide requires the original vehicle registration manual for an ownership transfer. A copy can help you review the vehicle’s details but cannot replace the original for the transfer. If the book is with a finance company, ask for evidence that the account has been settled and a date when the book will be available before paying.

Can the Book Show How Many Times a Vehicle Has Changed Owners?

Yes. Its transfer entries show the recorded changes of ownership. Several transfers in a short period are worth asking about, though they are not, by themselves, a reason to reject the vehicle.

Can I Sell a Vehicle That Is Still Being Financed? Who Has the Book?

It can be sold, but the finance account must be settled before ownership can be transferred to the buyer. While payments are ongoing, the finance company holds the book and its name appears in the registered owner entry. State this status in the listing from the start.

When Should the Seller Hand Over the Original Book?

Bring the original book when both parties attend the transport office for the transfer, rather than handing it over before receiving payment. Attending together lets both parties complete the paperwork within the 15-day notification period under Section 17 of the Motor Vehicle Act B.E. 2522.

What Is the Difference Between a Green and a Blue Registration Book?

In reported practice, green books are associated with motorcycles and blue or light blue books with private passenger cars. The Department of Land Transport’s B.E. 2562 regulation does not specify book cover colours. It identifies vehicle categories by รย. code, such as รย.1 for private passenger vehicles with no more than seven seats and รย.12 for motorcycles. Check the code inside the book rather than relying on its colour alone.

How Much Does a New Registration Book Cost?

For a lost or damaged book, there is a 5-baht application fee and a 50-baht fee for a replacement registration manual. Requesting a replacement annual tax disc at the same time adds 20 baht. If the tax record spaces are full and a new book is issued, the fee for the registration manual is 100 baht. These figures come from the Department of Land Transport’s fee schedule under the Motor Vehicle Act B.E. 2522.

Do I Need to File a Police Report If the Registration Book Is Lost?

The Department of Land Transport’s public guide does not list a police report among the documents required for a replacement manual. The B.E. 2562 regulation mentions either evidence of a police report or a statement from the owner, though that provision appears in the section on moving a vehicle. Contact the transport office where you intend to apply before travelling.

Are the Registration Book and Compulsory Motor Insurance the Same Document?

No. The registration book is the vehicle registration manual issued by the registrar. Compulsory motor insurance, often called Por Ror Bor (พ.ร.บ.) in Thai, is an insurance policy purchased from an insurer under the Motor Vehicle Accident Victims Protection Act. It is required before annual vehicle tax can be renewed.
