Your vehicle's identity — its VIN, engine number, and registration — forms a chain of identifiers that link to your road tax record. Understanding this chain helps you spot identity fraud, avoid cloned vehicles, and maintain clean ownership records.

Vehicle Identification Numbers and VED

The Vehicle Identification Number (VIN) is a unique 17-character code assigned to every vehicle at the factory. The VIN is permanently stamped into the chassis and cannot be legally changed. When you register a vehicle with DVLA, the VIN is recorded alongside the road tax record. Any discrepancy between the VIN on the V5C and the physical VIN on the vehicle is a major red flag — suggesting the vehicle has been cloned, stolen, or the records have been tampered with.

Engine Numbers and Tax Records

The engine number is also recorded on your V5C and linked to your road tax record. Like the VIN, the engine number is used as a secondary identifier to confirm the vehicle's identity. If an engine is replaced, you must notify DVLA of the new engine number — and the change should be noted on the V5C. Failing to update these details means your vehicle's records are inaccurate, which can cause problems when selling or transferring the vehicle.

Preventing Vehicle Identity Fraud

Vehicle cloning — where a thief copies a legitimate vehicle's registration plate and VIN — is one of the most common forms of vehicle fraud. A cloned vehicle may appear to be legally taxed, but the tax belongs to the legitimate vehicle, not the clone. Cloned vehicles often have fake or borrowed identities. Always check the VIN physically before buying a used car, and compare it against the V5C. If they do not match, walk away.

What Happens to Tax When Identity Is Disputed?

If DVLA discovers a discrepancy between the vehicle's physical identity and its registration records, it will freeze the road tax — the vehicle cannot be taxed or transferred until the discrepancy is resolved. If you have purchased a cloned vehicle unknowingly, you will lose both the vehicle and any money paid. The legitimate registered keeper retains the right to the vehicle's identity, and the cloned copy is seized.

Checking Before Purchase

Before buying any vehicle — new or used — check the VIN against the V5C and any service records. You can also run a history check using services like HPI, RAC, or the AA to confirm the vehicle's identity, mileage, and ownership history. These checks cost around £20-£30 but can save thousands by identifying cloned, stolen, or finance-disputed vehicles before you buy.

Reporting Identity Concerns

If you suspect vehicle identity fraud — either that your vehicle has been cloned or that you have encountered a cloned vehicle — report it to the police immediately. DVLA also has a dedicated team for vehicle identity concerns. Do not attempt to resolve the issue yourself or confront suspected fraudsters directly. For your own road tax record, if your vehicle has been cloned, contact DVLA and your insurer as well as the police.
