Common VIN Decoder Issues & What They Mean
A free VIN decoder can reveal important details about a car’s history. If your decoder report contains warnings, understanding them can help you avoid costly mistakes. Below are the most common VIN decoding issues and what they mean.
What Does ‘Outstanding Finance’ Mean in VIN Decoder Results?
If a vehicle still has outstanding finance, it means the previous owner took out a loan that hasn’t been fully repaid. Until the debt is cleared, the lender legally owns the vehicle. If you purchase a car with unpaid finance, you could risk losing it if the lender repossesses it. A full vehicle history check can confirm if a car is free from financial ties.


What Happens If a Car Is Reported Stolen?
A stolen vehicle warning indicates the car has been flagged as missing or illegally taken. Buying a stolen vehicle can lead to serious legal consequences, including seizure by the police. Before purchasing any used vehicle, always use a VIN decoder to ensure it hasn’t been reported stolen or involved in fraud.
How Can I Spot a Mileage Discrepancy Using a VIN Decoder?
A mileage discrepancy occurs when a car’s odometer reading has been altered to appear less used. Some sellers roll back mileage to increase a car’s value, but this is a form of fraud. A full VIN history report compares recorded mileage from different sources, helping you detect any inconsistencies and avoid overpaying.

What Does a VIN Number Reveal?
The 17-character VIN is divided into sections. Each section provides unique information about the vehicle:
WMI (World Manufacturer Identifier)
The first three characters show the country of origin and manufacturer.
VDS (Vehicle Descriptor Section)
Characters 4–8 describe vehicle attributes such as model, body style, engine type and restraint system.
VIS (Vehicle Identifier Section)
Characters 9–17 form a unique serial identifier, including model year and assembly plant.
Check Digit
The 9th character verifies the VIN’s authenticity via a mathematical formula.

Where to Find Your VIN
Your VIN appears in several secure places on the vehicle and on documents. Check the most common locations below.
Dashboard
Look through the windscreen on the driver’s side dashboard to find the VIN plate.
Driver’s Door Pillar
Open the driver’s door and check the inner side of the door pillar for the VIN plate.
Under the Bonnet
Locate the VIN stamped on the engine block or firewall.
Free VIN Decoder vs Full Vehicle History Report
Our free VIN decoder delivers basic data for every vehicle (including pre-1981 formats), while a full history report goes deeper by using paid global databases to give you complete peace of mind before you buy.
Free VIN Decoder
Our free VIN decoder lets you decode any VIN number, chassis number, or vehicle identification number—including legacy pre-1981 formats—to reveal make, model, year and basic equipment info. This service is completely free and provides instant results.


Full Vehicle History Report
A full vehicle history report includes everything a free decoding gives, plus detailed mileage rollback checks, theft records from law enforcement, accident and damage history (including photos where available), outstanding finance information, ownership history, registration data and title details such as taxi usage or flood damage. This comprehensive data comes from paid global databases.
Why Choose a Full Report?
While free VIN decoding saves time, only a full report uncovers hidden issues like salvage titles, import discrepancies or water damage. Investing in a complete history check ensures you buy with confidence.

What If the VIN Check Says ‘Invalid VIN’?
