Verify the Vehicle Identification Number

What is a Vehicle Identification Number?
A VIN is a 17-character alphanumeric code assigned to every motor vehicle when it leaves the factory. Each code is globally unique — no two vehicles ever receive the same sequence, making it the definitive identifier for any individual car.
The code breaks into three sections: the opening three characters form the World Manufacturer Identifier (WMI), pinpointing the maker and country of production. Characters four to nine make up the Vehicle Descriptor Section, encoding body style, model line, and engine type. The remaining eight characters are the Vehicle Identifier Section — a serial number unique to that single vehicle off the production line.
The VIN is both stamped into the vehicle's chassis and displayed in several readable locations — dashboard, door frame, and V5C logbook. Because the stamped chassis impression is difficult to alter without visible signs, it remains the most dependable way to establish a vehicle's genuine identity.
Note: VIN and chassis number are distinct things. The chassis number is a mark pressed into the vehicle's frame — it overlaps with part of the VIN but cannot be used in its place. Only the full 17-character code carries legal and registration weight.

VIN Fraud: The Risks of Not Checking
VIN tampering and plate cloning are among the most common forms of vehicle identity fraud in Ireland.
Plate Cloning
Criminals copy the registration plates and VIN from a legitimate vehicle and attach them to a stolen one. The stolen car then appears clean on basic checks — because the details belong to a real, honest vehicle.
VIN Tampering
The physical VIN plate or stamped chassis number is altered or replaced to disguise a vehicle's true identity. This is common with high-value stolen cars that criminals intend to sell through private channels.
Logbook (V5C) Fraud
Forged or altered V5C documents are used to create false ownership records. If the VIN in the logbook doesn't match the vehicle, it's a strong indicator of fraud — check both before handing over any money.
'Ringing'
A specific fraud where a stolen vehicle is given the identity of a legitimately owned write-off of the same make and model. The 'ringed' car then passes visual checks and appears to have a genuine history.
Where to Find the VIN on a Vehicle
Before buying, physically check all four locations and confirm they all show the same number.
Dashboard plate
Visible through the windscreen on the driver's side. Usually a small metal or adhesive plate riveted to the top of the dashboard.
Driver's door jamb
A sticker or plate inside the door frame on the driver's side. Contains the VIN alongside tyre pressure and paint codes.
Engine bay
Stamped directly onto the chassis rail or strut tower. This is the hardest location to alter, making it the most reliable for fraud checks.
Vehicle Registration Certificate (VRC)
Listed on the Irish registration document issued by the RSA. Must match all physical locations exactly — discrepancies are an immediate red flag.
If any location shows a different number, do not buy the vehicle. Mismatched VINs are a clear sign of tampering, fraud, or a previously stolen identity. Walk away and report the seller to Action Fraud.
What the check confirms

Frequently asked questions
A Vehicle Identification Number (VIN) is a unique 17-character alphanumeric code assigned to every motor vehicle by its manufacturer. It encodes the country of manufacture, maker, vehicle type, engine specification, model year, and a unique serial number. No two vehicles in the world share the same VIN.
They are related but not identical. The chassis number is physically stamped onto the vehicle's frame and is part of the VIN sequence. The full 17-character VIN is used for official records, history checks, and registration purposes.
The VIN appears in several locations: on a plate on the driver's side dashboard (visible through the windscreen), inside the driver's door jamb, stamped in the engine bay, and on the VRC registration document. All locations must match.
Our VIN check retrieves the VIN recorded at the RSA for the registration number you enter and confirms whether it matches the VIN on the vehicle. A mismatch is a serious warning sign of potential identity fraud.
Yes — absolutely. If the VIN on the dashboard doesn't match the VRC, door jamb, or engine, this is a serious red flag suggesting possible plate cloning, ringing, or VIN tampering. Never buy a vehicle with mismatched VINs without expert inspection.
Cloning is when criminals copy the registration number and VIN from a legitimate vehicle onto a stolen one. The stolen vehicle then passes basic number plate checks because the details match a real, clean car. A physical VIN inspection combined with our RSA check helps uncover this.
Our VIN check works for any Irish-registered vehicle with a RSA record.
We retrieve VIN data directly from the RSA (Road Safety Authority), which maintains the National Vehicle & Driver File — the official government record for every registered vehicle in Ireland.
