Check the chassis and engine numbers stamped on the vehicle against the CR book, confirm the seller matches the registered owner's NIC, and cross-check the registration on DMT eServices before you pay. If anything doesn't match exactly, walk away or verify at an RMV office first.
How to tell if a used car's CR book is fake in Sri Lanka
Check three things before you pay a single rupee: the chassis number stamped on the vehicle, the engine number, and the seller's NIC against the name on the CR book. Then run a free check on DMT eServices to confirm the registration details match. If the book is a "duplicate," if numbers don't line up exactly, or if the person selling isn't the registered owner and can't show written authority, stop and get it checked at an RMV office before you go any further.
Forged and altered CR books are one of the oldest tricks in Sri Lanka's used vehicle trade. Buyers have lost money to doctored registration papers for years, and the same checks that caught those cases still work today.
Key facts
- Every vehicle has its chassis number stamped in at least two physical locations — not just printed in the CR book.
- DMT eServices (eservices.motortraffic.gov.lk) offers a free "Limited Vehicle Information Request" using the registration number and chassis number.
- A "Full Information" request on the same portal costs a small online payment (Rs. 150 as listed on DMT's charges page) as of November 2026 — confirm the current fee on dmt.gov.lk before paying.
- A CR book marked "duplicate" means the original was reported lost to police and replaced — it isn't proof of fraud by itself, but it needs more scrutiny.
- The registered owner's name and NIC on the CR book must match who is actually selling you the vehicle, or you need written authorisation from the owner.
- Genuine CR books have specific paper, watermarks, official stickers, and a consistent font style that forged copies often get slightly wrong.
- If you're unsure, the RMV can confirm whether a registration certificate's details are genuine against their own records.
- Buying on a fake or altered CR book can mean you never get the vehicle properly transferred into your name, even after you've paid.
What does a genuine CR book look like?
A genuine CR book uses a specific type of paper, has watermarks, carries official RMV/DMT stickers, and uses a consistent font and letter style throughout. If you've seen a real CR book before (a friend's, a family member's), you'll notice when something feels slightly off on a seller's copy — paper that feels thinner, printing that looks smudged, or a sticker that looks reprinted rather than original. This isn't foolproof on its own, but it's your first signal to slow down and check further.
How do you check the chassis and engine numbers?
Every vehicle has its chassis number stamped into the metal in at least two places, commonly on the chassis frame itself and on a plate near the engine bay or windscreen. Physically find both stampings and compare them, character by character, against what's written in the CR book. Pay close attention to characters that are easy to swap in a forgery, like the digit "0" versus the letter "O." Do the same for the engine number. If either number doesn't match exactly, don't assume it's a typo — treat it as a reason to stop the deal until it's explained and verified.
This matters more for older vehicles or ones bought through an intermediary than for a car bought straight from a known first owner, but it costs you nothing to check every time.
Can you verify the CR book with RMV or DMT before paying?
Yes, and you should. Go to DMT eServices, select the Limited Vehicle Information Request, and enter the registration number and chassis number exactly as they appear on the CR book. This free check tells you whether the basic registration details on record match what the seller has shown you. If you want more detail, the Full Information request is available for a small online payment — check the current amount on DMT's own charges page, since fees can change.
If anything about the check doesn't add up, or the online portal isn't accessible to you, you can also take the CR book and the vehicle's actual chassis and engine numbers to the relevant RMV office and ask them to confirm the certificate against their records. This is a normal request, and RMV staff are used to buyers asking before a sale goes through. Running this check before you pay a deposit costs you a short delay; skipping it can cost you the whole price of the vehicle.
What if the CR book says "duplicate"?
A duplicate CR book is issued after the original is reported lost, usually with a police report as part of the process. It's not automatically a red flag, but it deserves more questions, not fewer. Ask the seller directly why the original was lost, how long ago, and ask to see the police report reference if they have it. Duplicate books have historically been linked to some fraud cases where a vehicle was reported "stolen" or "lost" deliberately so a second set of papers could be produced. That doesn't mean every duplicate book is suspicious — just that you should match the chassis and engine numbers even more carefully when you're looking at one, and lean more heavily on the DMT eServices check and, if in doubt, an RMV office visit.
What are common CR book scams in Sri Lanka?
The two patterns that keep coming up in reported cases are: a vehicle circulating with two different registration books under two different owners (often linked to a vehicle that was actually stolen), and sellers producing altered or copied registration papers where key details — like the chassis number or owner details — have been changed to hide the vehicle's real history. In some past cases reported in the media, vehicles hired out through rent-a-car arrangements were later falsely reported stolen so a duplicate book could be obtained and the vehicle resold without the original owner's knowledge. None of these scams survive a buyer who actually checks the stamped chassis number against the book and confirms the registration on DMT eServices before paying.
What mistakes do buyers make?
The most common mistake is trusting the CR book at face value because it "looks official" without physically checking the stamped chassis number on the vehicle. The second is paying a deposit to lock in a deal before any verification, which puts you in a weak position if something turns out to be wrong. The third is not asking who the seller is in relation to the registered owner — if the person selling isn't the name on the CR book, you need to see written authority from the actual owner, not just take their word for it. Finally, some buyers skip the RMV or DMT check entirely because it feels like extra hassle, right before the one deal where it would have mattered.
Checklist before you pay
- Physically locate the chassis number in at least two places on the vehicle and match it character-by-character against the CR book.
- Match the engine number the same way.
- Confirm the seller's NIC matches the registered owner's name on the CR book, or get written authority if they're selling on someone else's behalf.
- Run a free Limited Vehicle Information Request on DMT eServices using the registration number and chassis number.
- If the book is marked "duplicate," ask why and when the original was lost.
- If anything feels off, take the CR book and vehicle details to an RMV office and ask them to confirm it against their records before you pay anything.
- Only hand over a deposit or full payment after all the above checks are done.
Before you start viewing vehicles, browse listings on Wahanaya's vehicles page and check what similar models are going for on price check, so you know roughly what you should be paying once the paperwork checks out. If you're financing the purchase, Wahanaya's leasing calculator can help you work out a monthly payment before you commit. For more on buying safely in general, see Wahanaya's safety tips, and if you run into a CR book or seller situation that doesn't fit neatly into this guide, ask other buyers and sellers in the Wahanaya forum — someone has likely seen a similar case before.
