Request the VIN privately, offer to verify it in person and pause payment when the vehicle's identity remains unclear.
Refusing the VIN prevents you from checking vehicle identity before purchase. Privacy concerns may exist, but resolve them before money changes hands: privately or at the vehicle, without pressure for a deposit.
Start with the vehicle number
Start with available technical details for free. The OBDAuto decoder does not provide accident, mileage, theft or service history.

Screenshot source: carVertical ↗ Buying guide Editorial review: 22 October 2026Resolve any difference between vehicle markings, documents and the report before paying a deposit. An empty report does not confirm that the car has never been damaged.
Request a clear photo of the VIN on the car and the relevant documents, then arrange dates and mileage readings in order. Keep a budget for an independent inspection.
Refusal alone does not prove fraud. If reasonable options still do not allow identity and document checks, pause the transaction.
Your first check at the car

Some models show the VIN through the windscreen. A door-frame label or a stamped marking may be elsewhere; check the manufacturer’s manual for your model.
Compare the marking with the vehicle documents and report. Do not confuse an engine code or a part number with the VIN.
Do not scrape or alter markings. If a number is missing, hard to read or does not match, ask a specialist to verify the vehicle’s identity.
Explain that you need the full VIN to compare documents and available data. You are not requesting a national personal number, a full identity-document copy or other owners' details. Offer a private channel and a photograph of the marking with unnecessary personal information masked.
If the seller will not send it, propose a viewing or independent inspection before any deposit. Compare the marking with original documents there. A partial VIN can sometimes identify a variant but cannot replace the full VIN for history checks.
'Before arranging travel, I need the full VIN to compare documents and check available information. You can send it privately without personal details. Alternatively, we can check it together at the car or during an independent inspection before any deposit. Would that work?'
Keep the reply and advert. If the VIN is provided, compare all 17 characters with documents and the vehicle; a plausible decoder result does not establish that the VIN belongs to the advertised car.
Confirm identity, then collect national and service records. Consider a commercial report where it can add relevant information to outstanding questions. Arrange inspection and compare findings with the advert.
If you have already paid and suspect a scam, preserve conversations, payee details and documents, promptly contact your bank or payment provider and then the relevant authorities. Do not send another amount described as a 'refund release fee'.

I requested the VIN privately. I avoided requesting unnecessary personal details. I offered verification at the car or workshop. I compared the full VIN with original documents. I independently verified any payee. I paused payment until identity checks were resolved.No. It materially limits checking but is insufficient evidence for an accusation.
Is the VIN on a supplied report sufficient?No. Match it to the vehicle marking and original documents before payment.
Must I buy a report before viewing the car?No. Start with identity and accessible documents, then decide which additional check is useful.
