Buying a used car is always associated with risks: incorrect mileage, a history of accidents, inconsistency of documents with real characteristics. The only reliable way to get reliable information about a car is check it by VIN code. This unique identifier, like a fingerprint, stores data about the model, configuration, year of manufacture and even operating history.

But how to correctly decipher the VIN? Where can I find it by car? And which services provide the most complete information - free or paid? In this guide we will look at all verification methods, from basic decoding to in-depth analysis of car history, including hidden nuances that resellers are silent about. You'll learn how to tell a real VIN from a fake one, what data you can get legally and what you'll have to pay for, and why some reports can be misleading.

What is a VIN code and where to look for it on a car

VIN (Vehicle Identification Number) is 17-digit alphanumeric code, which is assigned to the vehicle at the factory and remains unchanged throughout its entire service life. It contains information about the manufacturer, model, year of manufacture, engine, transmission and even country of assembly. The VIN structure is regulated by international standards ISO 3779 and ISO 3780, therefore it is deciphered the same for all brands - from Lada up to Porsche.

Where to look for VIN on a car:

  • 🔍 Windshield (bottom driver's side, visible from outside)
  • 🚗 Under the hood (on body plate or frame)
  • 🔧 In the driver's door opening (on sticker or engraving)
  • 📄 In documents: STS, PTS, insurance policy

⚠️ Attention: If the VIN on the body and in the documents do not match, this is a sign of a broken number. It’s better not to buy such a car, even if the seller assures that it’s “just a typo.” A broken VIN automatically makes the car stolen or assembled from several cars (the so-called "constructor").

On the windshield
In the doorway
Under the hood

I don't check

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

Each character in the VIN code carries specific information. It is deciphered according to the following principle:

Position Meaning Example
1–3 World Manufacturer Index (WMI) XTA — Toyota (Japan)
4–8 Vehicle description (VDS): model, body type, engine 22LZE — Camry, sedan, 2.5L
9 Check digit (for authentication) 5
10 Model year J — 2018
11 Manufacturer code 6 - plant in St. Petersburg
12–17 Vehicle serial number 123456

For self-decryption:

  1. Take the first 3 characters and check them against NHTSA database (for foreign cars) or Vinformer (for domestic ones).
  2. The 10th character will indicate the year of manufacture (for example, A = 2010, B = 2011, ..., L = 2020).
  3. Check the 9th character (check digit) with calculation algorithm - if it doesn’t match, the VIN is fake.

Check the code on the body and in the documents

Check check digit (9th character)

Make sure that the font and engraving are uniform (there are no signs of forgery)

View the VIN through a magnifying glass for any overlaps-->

⚠️ Attention: On some American cars (for example, Ford or GM) The 8th character can indicate the type of fuel: G - gasoline, D — diesel, E - electric. In European cars, this information is usually encoded in 4–8 characters.

Free services for checking VIN: what they show and where the catch is

There are dozens of services on the Internet that promise “a complete car history by VIN for free.” In practice, most of them only give basic data: make, model, year of manufacture and technical specifications. In-depth reports (accidents, mileage, owners) are almost always paid. Here's what you can actually learn for free:

  • 📋 VinDecoderz — VIN decoding according to manufacturer standards (without history).
  • 🔧 AutoDNA — basic information + photos of similar cars (without accident data).
  • 🚘 State Traffic Safety Inspectorate of the Russian Federation — check for theft, restrictions and participation in accidents (only for Russian cars).
  • 🌍 CarVertical — mileage and insurance history (free only for some countries).

The catch of free services:

  • 🔄 They often show outdated data (for example, mileage at the time of last check).
  • 📊 Some “inflate” the accident history, including minor insurance claims (for example, a scratch in a parking lot).
  • 💰 A free report can be cut down version paid, where key data is hidden.
💡

Before buying a car, check the VIN in at least 2-3 services. For example, traffic police data on an accident may not coincide with the CarVertical report - this is a reason to ask questions to the seller.

If you are seriously considering buying a used car, a paid report (costing from 300 to 1500 rubles) can save thousands on hidden problems. But not all services are equally useful. Here's what's worth checking for a fee:

Data Where to get it Cost
Full accident history (with photo) CarVertical, AutoCheck 500–1200 ₽
Mileage (according to service station archives) VinHistory, Carfax 400–900 ₽
Number of owners traffic police (through government services) or Autocode 350 ₽
Customs history (for imported cars) Federal Customs Service of the Russian Federation or VinInfo 600–1500 ₽

How not to overpay:

  • 🛒 Search promotional codes — many services give discounts on the first reports.
  • 📑 Check if data is duplicated. For example, Autocode and CarVertical can take information from the same sources.
  • 🔍 For cars older than 10 years, a paid report is often not justified — the story may be incomplete.
What data will NOT be shown by any report?

No service will give a 100% guarantee that:

- The mileage is not adjusted after the last entry in the database (for example, if the car was driven from Europe and the tidy was “reset to zero”).

- The car was not involved in an accident if the owners settled the damage without insurance (“by agreement”).

- The engine or body is original - this can only be verified by an expert.

What to do if the VIN is unreadable or missing

Sometimes the VIN code is erased, interrupted or hidden (for example, under a layer of paint). In such cases:

  1. Try cleaning the VIN area with solvent (for example, White spirit) - sometimes the room is simply dirty.
  2. Use UV flashlight (365 nm) - on some cars, the VIN is applied with paint that glows in ultraviolet light.
  3. Check duplicate signs:
    • On the frame under the hood (for SUVs).
    • On the floor in the trunk (under the carpet).
    • In the glove compartment (on some Japanese cars).
  • If the VIN is missing at all, ask examination at the traffic police - they can restore the number using the factory databases.

    • ⚠️ Attention: If the seller refuses to provide the vehicle for VIN inspection or offers “alternative verification methods” (for example, by body number), this a sure sign of fraud. It is better to refuse such a deal.

    💡

    Even if the VIN is found, always check it with the data in the vehicle title. Discrepancies in one number may mean that the car is stolen or assembled from different cars.

    How to check the history of a car by VIN through the traffic police and other government resources

    In Russia, official information about a car can be obtained through government services. This is data that you can trust 100%:

    • 📄 Public services (www.gosuslugi.ru) - check for theft, restrictions (arrest, bail), registration history.
    • 🚔 Traffic police website (traffic police.rf) - participation in an accident (only if they were officially registered).
    • 📑 Federal Customs Service of the Russian Federation — for imported cars (checking customs clearance and legality of import).

    How to get data:

    1. Go to Public services → "Transport and driving" → "Checking the car."
    2. Enter VIN or license plate number.
    3. The system will show:
      • Being wanted.
      • Restrictions on registration actions.
      • Ownership history (if the car is registered in Russia).

    ⚠️ Attention: Government resources don't show mileage, engine condition or accident facts, if they were not registered through the insurance company. For a complete picture, use them together with paid services.

    Top 5 mistakes when checking a car by VIN and how to avoid them

    Even experienced shoppers sometimes miss important details. Here are the most common mistakes:

    1. Trust only one source. For example, they check cars only through Autocode, without checking the data with the traffic police.
    2. Ignore check digit. If the 9th character of the VIN does not match the calculated one, the code is fake.
    3. Duplicate VINs are not checked. Fraudsters may leave the original number on the windshield, but replace it on the frame.
    4. Buy the "eatery" report. Some services sell cut-down data for the price of a full report.
    5. They don't pay attention to little things. For example, if the report indicates mileage of 150 thousand km, and the odometer shows 90 thousand, this is a clear sign of twisting.
      6. 💡

      Before buying a car with a mileage of more than 150 thousand km, be sure to check the condition of the engine and gearbox at a service station. Even if the VIN history is clean, wear can be critical.

      FAQ: Frequently asked questions about checking a car by VIN

      Is it possible to find out if a car is totaled by the VIN?

      Yes, but not always. Services like CarVertical or AutoCheck show road accidents registered through insurance companies. However, if the damage was repaired “by agreement” without insurance, this will not be reflected in the report. For accuracy, inspect the car on a lift - traces of body repairs are often visible in welds or uneven gaps.

      What to do if the VIN does not pass the authentication check?

      If the check digit (9th character) does not match the calculated one, or the font of the number is not uniform, this is a sign of a fake. Refuse the deal and notify the traffic police - such a car could be stolen or assembled from several cars. Check VIN via traffic police website for theft.

      Is it possible to find out the actual mileage using the VIN?

      The mileage in the reports is taken from the archives of service stations, insurance companies and dealerships. However, if the odometer was changed after the last entry in the database, the services will show outdated data. To check, check the mileage in the report with what is indicated in the service book (if there is one) and on the dashboard.

      How to check the VIN on a foreign car?

      For imported cars use:

      • CarVertical or Carfax (for USA, Europe).
      • JEVIC (for Japanese cars).
      • Official databases of the manufacturer (for example, Mercedes-Benz or Volkswagen).

      Pay attention to the customs history - if the car was imported illegally, it may be confiscated.

      How much does a full car check by VIN cost?

      The cost depends on the depth of the report:

      • Basic decoding (make, model, year) - free.
      • Theft check and restrictions (traffic police) - 350 ₽.
      • Full history (accidents, mileage, owners) - 500–1500 ₽.
      • Examination of the authenticity of VIN (at the traffic police) - from 2000 ₽.

    For cars over 1 million rubles, it is recommended to order full report + inspection at the service station (about 3-5 thousand ₽).
