VIN check digit
The VIN format and position-9 check digit pass the local validation check.
Paste a seller listing and enter the VIN to catch obvious year, make, model or odometer red flags before you spend money on a history report, inspection, deposit or travel.
Direct answer
A VIN listing match can catch obvious mismatches between the seller listing and decoded VIN signals such as model year, make and model. It cannot prove clean title, ownership, lien status, accident history, odometer accuracy or completed recalls. Use it as a first screen, then confirm the physical VIN, paperwork, recall sources, vehicle history and inspection.
1-Click Sample Listing Scenarios:
No obvious listing mismatch
The VIN format and position-9 check digit pass the local validation check.
Listing year 2003 matches the decoded model-year code.
Listing make honda matches the decoded make signal.
Model, trim and engine fields can be blank or ambiguous in VIN datasets; compare registration and service records.
VIN decoding does not verify mileage. Compare the listing, dashboard, service records and history report.
A listing match is only a first screen. Check NHTSA, Transport Canada, the manufacturer, lien/title records and an inspection before buying.
How to triage discrepancies between marketplace ads (Kijiji, AutoTrader, Facebook Marketplace) and decoded vehicle signals before putting down a deposit.
| Signal Mismatch | Risk Level | Probable Scenario | Immediate Action Required |
|---|---|---|---|
| Invalid Check Digit (9th Char) | CRITICAL STOP | Fabricated or cloned VIN. Seller transposed characters intentionally or created a fake identity number. | Do not wire money or travel. Request a clear photo of the dashboard VIN plate and driver door jamb B-pillar sticker. |
| Model Year Discrepancy (10th Char) | HIGH RISK | Common seller deception: advertising a 2013 vehicle as a 2015 to inflate asking price by $3,000–$5,000, or curbsider bait-and-switch. | Verify the vehicle ownership registration permit (UVIP in ON) before test-driving. Never accept seller excuses like "first registered in 2015". |
| Make or Model Mismatch | CRITICAL STOP | Stolen VIN harvested from another clean listing, or template copy-paste fraud to bypass marketplace safety checks. | Cease all communications. Report the marketplace listing. Do not reveal personal information or meet the seller. |
| Severe Odometer Anomaly (<5k km/yr) | CAUTION / AUDIT | Possible digital cluster rollback, swapped instrument cluster, or long unrecorded non-operational period. | Inspect CARFAX/UVIP historical mileage stamps sequentially. Cross-reference oil change window stickers and tire date codes (DOT). |
| Unrepaired Safety Recalls | ACTION ITEM | Manufacturer defect (airbag inflators, steering shafts, fuel pumps) never completed at an authorized dealer. | Safety recalls are fixed free of charge by authorized franchise dealers. Demand proof of remedy or book appointment prior to purchase. |
