Looking for the VIN?
Here is there you’ll find it:
Since 1981, every vehicle identification number has followed ISO Institute standards. This 17-character sequence interprets your vehicle's history, specifications, and records. Using a VIN decoder helps buyers verify authenticity, check recalls, and understand vehicle attributes before making purchase decisions.
The process takes just minutes with our free online tool.
Your vehicle identification number appears in several standard locations for security purposes.
| Key Risk | Impact on Buyers | Mitigation Steps |
|---|---|---|
| Theft Risk | The vehicle is stolen every 37 seconds in 2024 nationwide. | Verify VIN against NICB theft database. Install tracking/immobilizer systems. |
| Unrepaired Safety Recalls | Thousands of models still carry open recalls that reduce safety and resale. | Run VIN through NHTSA recall lookup. Ensure repairs are completed at GM dealers. |
| Depreciation Over Time | Older cars lose ~60% of their market value after 10 years of use. | Use VIN history to confirm condition. Buy at fair market price to offset losses. |
| Odometer Rollback Fraud | Roughly 10% of used cars show odometer inconsistencies. | Cross-check mileage across NMVTIS, service records, and EpicVIN timeline report. |
| Hidden Flood or Salvage History | ~910 cars listed on salvage auctions today, many without disclosure. | Decode VIN via NMVTIS and EpicVIN. Request detailed photos and auction history. |
Risk Reduction: Risk mitigation: Always verify VIN through EpicVIN and NMVTIS reports. Compare mileage and repair history. Require service records and photos before purchase.
| Issue | Affected Models, Symptoms, Average Repair Cost |
