Buying a used car always involves risks: hidden accidents, incorrect mileage, bank deposit or theft. The only reliable way to find out the real history of a car is check by VIN code. This 17-digit identifier contains information about the manufacturer, model, configuration, and even each repair. But how to correctly decipher the VIN, where to find it on the car, and which services provide the most complete information?

In this article you will learn how VIN decoders work in practice, which free databases available in 2026, and how to distinguish a fake report from a real one. We will also look at real cases where checking by VIN helped to avoid fraud when buying a car - with examples of reports and expert explanations.

What is a VIN code and why it cannot be faked

VIN (Vehicle Identification Number) is a unique β€œpassport” of the car, which is assigned at the factory and remains unchanged throughout the life of the car. It consists of 17 characters (numbers and Latin letters, except I, O and Q), which are divided into three parts:

  • πŸ”Ή WMI (World Manufacturer Identifier) β€” the first 3 characters indicating the manufacturer (for example, XTA β€” Toyota, WDB β€” Mercedes-Benz).
  • πŸ”Ή VDS (Vehicle Descriptor Section) β€” symbols 4 to 9, describing the model, body type, engine and other characteristics.
  • πŸ”Ή VIS (Vehicle Identifier Section) β€” the last 8 characters, where the year of manufacture, manufacturer and serial number are encrypted.

It is almost impossible to fake a VIN, since it is duplicated in several places of the car (for example, on the windshield, under the hood and in the vehicle title), and is also recorded in the electronic databases of the traffic police, insurance companies and dealerships. Even if fraudsters change the number on the body, the original VIN will remain in the car’s electronic systems (for example, in the engine control unit).

πŸ“ŠHave you ever checked a car by VIN before purchasing?
Yes, I always check
Checked it 1-2 times
No, I haven't checked
I don't know what VIN is

Where is the VIN on a car: 7 places to check

Manufacturers duplicate the VIN in several places to make it more difficult to counterfeit. Here's where to look:

  1. Windshield (bottom on the driver's side) is the most visible place, but the number here can be easily faked with a sticker.
  2. Under the hood - usually on a spar or a special plate (for example, Volkswagen - on the shock absorber strut).
  3. On the threshold of the driver's door β€” check the seal and mat, sometimes the number is hidden under them.
  4. In the trunk - under the spare wheel or on the rear wall (typical for BMW and Audi).
  5. On frame - SUVs and pickups (for example, Toyota Hilux or Ford Ranger).
  6. In PTS and STS β€” be sure to check the number with the one on the body.
  7. In electronic systems - some scanners (for example, Launch X431) read the VIN from the control unit.
πŸ’‘

If the number on the windshield and under the hood do not match, this is a 100% sign of interruption. Don't buy this car!

On some models (for example, Mercedes-Benz W211) VIN is also duplicated on ignition switch and even on keys. If the seller refuses to show all places with a number, this is a reason to be wary.

How to decipher the VIN code yourself: step-by-step instructions

You can independently find out basic information about the car by knowing the VIN structure. Here's how to do it:

Position in VIN Meaning Example
1–3 Manufacturer ID (WMI) JTE β€” Toyota (USA)
4–8 Description of the car (model, body, engine) ZZZ30R β€” Land Cruiser 300, diesel
9 Check digit (verifies the authenticity of the VIN) 5
10 Year of manufacture M β€” 2021
11 Manufacturer code A - plant in Japan

To decipher the year of manufacture, use this table:

  • πŸ“… A = 2010, B = 2011, ..., Y = 2030
  • πŸ“… 1–9 = 2001–2009
  • πŸ“… X, Y, Z - not used for years

β˜‘οΈ Independent VIN decoding

Done: 0 / 5

For accurate decryption, use online decoders (for example, VIN Decoder or NHTSA). They will even show body color and transmission typespecified by the manufacturer.

Free vs paid VIN checking services: what to choose

There are two types of services for checking car history:

  • πŸ†“ Free (traffic police, Autocode, CarVertical - limited reports) - show basic data (accidents, theft, restrictions).
  • πŸ’° Paid (Carfax, AutoDNA, VINCode) - give a complete history (mileage, repairs, owners, photos after the accident).

Let's compare popular services:

Service Cost What does it show Cons
Autocode From 349 β‚½ Accident, theft, bail, mileage No data on repairs
CarVertical From 599 β‚½ Full story, photo of the accident Expensive for a one-time check
traffic police Free Theft, restrictions, fines No data on mileage and repairs
Carfax From $39.99 Detailed history (US/Europe) Little data on Russian cars
πŸ’‘

To buy a car in Russia, it is optimal to use Autocode + CarVertical - they cover most databases.

If your budget is limited, start with free check on the traffic police website (check by VIN). It will show whether the car is listed as stolen or under arrest. For a complete picture, pay extra for the report at CarVertical - there is data about mileage twist and painting after an accident.

What data can be found out by VIN: complete checklist

The full VIN report includes more than 50 parameters. Here's what you need to check:

  • πŸš— Technical data: model, year of manufacture, engine size, gearbox type, body color.
  • πŸ’₯ Accident history: dates, severity of damage, photo (if available).
  • πŸ“‰ Mileage: data from the odometer at each maintenance (helps to identify twisting).
  • πŸ”’ Legal purity: theft, bail, traffic police restrictions, customs problems.
  • πŸ”§ Service: dates of maintenance, oil changes, repairs (if recorded at an authorized dealer).
  • 🏠 Number of owners: Frequent changes of owners are a reason to be wary.
  • 🌍 Import history: If the car was imported from the USA or Europe, check whether it was in a taxi or rental car.
Example of a real VIN report

In the report CarVertical for 2018 BMW 5 Series was discovered:

- An accident in 2020 with damage to the front bumper (photos attached).

- Mileage adjustment for 30,000 km (according to maintenance data).

- 3 owners in 2 years.

- The car was listed as collateral with the bank until 2021.

This allowed the buyer to reduce the price by 200,000 rubles.

Pay special attention photo after the accident β€” they show the real scale of damage. For example, if the report indicates β€œlight impact”, and the photo shows deformation of the spar, this is a reason to refuse the purchase.

Common VIN Fraud Schemes and How to Recognize Them

Fraudsters use VINs to scam buyers. Here are the most common schemes:

  1. Number interruption: VIN on the body is changed to hide theft or accident.
    ⚠️ Attention: If the number on the windshield and under the hood do not match the title, it is 100% fake. Also check if the numbers are erased when wiped with solvent.
  2. Replacement VIN: a number from another car (often from a salvage car) is glued onto the car. Checked through the traffic police database.
  3. Fake reports: the seller shows a β€œclean” report, but in fact the VIN in it has been replaced. Always check the report yourself!
  4. Hidden accidents: the report may not contain data on an accident if the repair was done β€œto the left”. Look for paint marks and uneven gaps between panels.

To avoid being scammed:

  • πŸ” Check the VIN in at least 2-3 services.
  • πŸ“Έ Take a photo of the license plate on the body and check it with the PTS.
  • 🚨 If the seller is in a hurry or refuses to provide the VIN, this is a red flag.
πŸ’‘

Before inspecting your car, download a VIN scanning app (such as VIN Scanner) - it will automatically check the number for authenticity.

Checking by VIN when buying a car: step-by-step algorithm

Follow this plan to avoid buying a problem car:

  1. Step 1: Get the VIN β€” ask the seller to send the number or take a photo of it yourself.
  2. Step 2: Check free databases:
  • Step 3. Order a paid report β€” CarVertical or AutoDNA (from 600 β‚½).
  • Step 4. Verify the data:
    • πŸ”„ Mileage in the report and on the odometer.
    • πŸ”„ Year of manufacture in VIN and PTS.
    • πŸ”„ Body color (sometimes cars are repainted).
    • Step 5. Inspect the car β€” look for signs of repairs, discrepancies in the interior (for example, other airbags).
    πŸ’‘

    If the report contains the entry β€œMileage not confirmed” or β€œNo data available”, this is a reason to bargain or refuse to purchase.

    If you have any doubts, order on-site diagnostics (costs from 1,500 β‚½). A specialist will check the car with a scanner and detect hidden problems.

    FAQ: Frequently asked questions about checking by VIN

    Is it possible to check a car by VIN for free?

    Yes, but free services (traffic police, Autocode) show only basic information: theft, accident, restrictions. For a complete history (mileage, repairs, owners), paid reports are needed.

    What to do if the VIN is unreadable or erased?

    If the number is erased or damaged, this is a reason to refuse the purchase. You can also try:

    • View VIN in PTS or STS.
    • Use a scanner to read the number from the electronic control unit.
    • Contact the traffic police to verify the data.
    Does the VIN show actual mileage?

    VIN itself does not store mileage data, but services like CarVertical collect information from service providers, insurance companies and dealers. If the mileage in the report differs greatly from the odometer, this is a sign of misuse.

    Is it possible to find out from the VIN whether the car was in a taxi?

    Yes, some services (for example, AutoDNA) show whether the car was listed in a car sharing or taxi service. This can also be seen from the high mileage (for example, 300,000 km in 3 years).

    What to do if the VIN report is β€œclean”, but the car is in doubt?

    Even a β€œclean” report does not guarantee the absence of problems. Required:

    • Check the car on a lift (traces of repair, rust).
    • Test on the go (knocks, vibrations, gearbox operation).
    • Order diagnostics from an authorized dealer.
