Thailand Motorcycle Green Book Explained
What the registration book records, what it does not prove, and the checks to make before you buy.
What is a Thai motorcycle green book?
Thailand's motorcycle registration book is the vehicle's official registration record, issued under the Department of Land Transport (DLT) system. It is commonly called the green book because of its cover. Cars typically have a different registration-book format.
The book helps connect a specific motorcycle to its recorded registration particulars and registered owner. It is important for ownership transfers, registration checks and other DLT transactions. It is not a substitute for checking the physical bike or confirming the seller is authorised to transfer it.
What information should you check?
Entries and formats may vary, but these are the details a buyer should review with the seller and, where necessary, the DLT office.
Check the name and relevant identifying details against the seller's identity and authority to sell.
Check registration number, make, model, engine and frame/chassis identifiers.
Review relevant entries, changes and whether the book reflects the current registration position.
Don't confuse the odometer with registration history
The book identifies the registered vehicle; it does not independently verify the mileage, service history, accident history or mechanical condition. Those need separate checks.

Do not rely only on a registration plate or a photograph of the book. Inspect the motorcycle itself and compare the recorded identifying numbers with the physical markings. Ask the seller to show you the relevant locations; if the markings are hard to read or appear altered, arrange an independent inspection.
Check that the engine information corresponds with the registration record, allowing for any properly recorded changes.
Find the manufacturer's frame or chassis identification and check for consistency, damage or tampering.
- Ask to see the original book rather than only a scan or photograph.
- Check the recorded owner's identity and the seller's authority to act.
- Compare registration and vehicle identifiers carefully.
- Confirm whether any finance, restrictions or pending transfer issues apply.
- Agree how and when the DLT transfer will be completed before paying in full.
What if the green book is missing?
A missing book is not automatically proof of wrongdoing, but it makes the purchase more complicated. There may be a legitimate replacement process, depending on the circumstances and who is entitled to apply. The buyer should not assume they can resolve it after paying.
Be especially cautious if the seller is not the recorded owner, claims the book is held by a lender, provides mismatched numbers, or says the paperwork can be fixed later without explaining how. Check directly with the relevant DLT office and obtain appropriate professional help where needed.
Safer position
Original registration documents, a seller with clear authority, consistent vehicle numbers and an agreed DLT transfer process.
Higher-risk position
Photocopies only, unexplained name differences, altered identifiers, unresolved finance or pressure to pay before verification.
How the green book fits into the transfer
Buying the motorcycle and updating its registration are separate tasks. The DLT process generally requires an application and supporting documents, with requirements depending on the circumstances and local office. A foreign buyer may need appropriate identity and address evidence. Confirm the current list with the office handling your transaction.
Inspect the book, vehicle numbers, seller identity and any outstanding issues.
Agree the required forms, identification, supporting evidence and who will attend the DLT.
Submit the transfer and confirm the updated registration record reflects the new owner.

Protect the motorcycle after registration
Check the motorcycle's compulsory cover (Por Ror Bor) and whether additional insurance is appropriate. Compulsory cover is not the same as comprehensive protection for damage, theft or liability.

Does a green book prove I own the motorcycle?
It records registered ownership, but you should also verify the seller's authority, the vehicle identity and whether any finance or other restrictions affect the transaction.
Can a foreigner be named in a Thai motorcycle green book?
Foreigners can register motorcycles subject to the applicable identity, address and DLT documentation requirements. Check the current requirements at your local office.
Should I buy a motorcycle without its original green book?
Not without verifying the reason it is missing and the lawful replacement or transfer route with the DLT before paying.
Is a green book the same as motorcycle insurance?
No. The green book is a registration record. Insurance and annual registration-related obligations are separate matters.
Can the registration details be changed after an engine replacement?
Changes affecting recorded vehicle particulars may need to be reported and approved through the DLT. Check before buying a modified motorcycle.
