Compare the identifiers before you buy
Copy the identifier from the vehicle itself and compare it character for character with the registration and seller’s paperwork. Use the owner’s manual for the precise location on that model; dashboard, body-label and chassis locations vary. Stop and resolve any mismatch before paying for a history search.
Request a vehicle-specific specification and provenance file
For a modern Rolls-Royce, compare the VIN with the registration and supporting build documentation. For a historical car, establish the period chassis-number format before selecting a lookup service. Individually commissioned details require records beyond a broad model identification.
Review restoration and bespoke claims carefully
Ask for invoices, photographs and specialist findings supporting significant restoration or changes to commissioned equipment. Verify current condition independently, including any features central to the asking price. Decoding cannot authenticate an entire bespoke commission, certify original components or establish a complete chain of ownership.
Limits to keep in mind
- VIN decoding identifies available specification data; accident, mileage, theft and ownership records require separate evidence and depend on the provider and country.
- NHTSA vPIC uses manufacturer submissions for the US regulatory system. International, low-volume and older vehicles may return incomplete results; an empty field is not proof that a vehicle is fraudulent.
- Historical chassis and frame numbers may not fit a modern 17-character VIN form. Preserve the identifier exactly as recorded on original documents.
From VIN details to a buying decision
Match the identifiers and documents, then investigate the countries where the vehicle was used. Read our cross-border guide or start with US records where relevant. Specifications do not establish current condition.
Compare report providers and use the viewing checklist.
