Are you faced with choosing a used car, but the seller cannot accurately name the model or year of manufacture? Or do you need to clarify the equipment of the car before purchasing spare parts? In such cases search for car model by VIN becomes the only reliable way to obtain reliable information. This unique 17-digit code is like a car passport, which encodes data about the manufacturer, characteristics and even repair history.

In this article we will look at where to find the VIN on a car, how to decipher it correctly (including hidden characters for different countries), and which services provide the most complete information for free. We will pay special attention a common mistake with fake VIN codes on American cars after 2010 - even experienced buyers miss it. And at the end you will find a checklist for quickly checking the car before the transaction.

What is a VIN code and why it cannot be faked

VIN (Vehicle Identification Number) is a unique vehicle identifier that is assigned at the factory and remains unchanged throughout the “life” of the vehicle. It consists of 17 characters (numbers and Latin letters, except I, O and Q due to the similarity with numbers). The code structure is regulated by an international standard ISO 3779-1983, so its format is the same for all manufacturers - from Toyota Corolla up to Ferrari SF90 Stradale.

It is technically possible to fake a VIN, but it is extremely difficult due to:

  • 🔹 Multiple duplication: the code is stamped on the body, chassis, plates in the interior and even on some spare parts (for example, on the engine block of BMW).
  • 🔹 Protected characters: The 9th character (check digit) is calculated using a special algorithm and checked by online services.
  • 🔹 Traffic police and customs databases: When re-registering a vehicle, the code is checked against the original records.
⚠️ Attention: On cars from the USA after 2010, there are often “broken” VINs on the windshield (where the code is duplicated on a sticker). Always check it against the stamp on the body under the hood!

Interesting fact: starting from 2021, the EU has introduced mandatory VIN marking on 14 key units (including airbags and ECUs) to make it more difficult to steal and change license plates. In Russia, a similar requirement applies only to premium cars (Mercedes-Benz, Audi, Lexus).

Where to look for the VIN code on a car: 7 verified places

Manufacturers duplicate the VIN at several points, but not all of them are available for inspection without a lift. Here's where to look for the code in order of convenience:

  1. Windshield (bottom driver's side) is the most visible place, but the sticker is easy to fake.
  2. B-pillar plate (on the driver’s side, under the door seal) - data on the permissible weight and tires is also indicated there.
  3. Under the hood:
    • On Japanese cars (Toyota, Nissan) - on the partition between the engine compartment and the passenger compartment.
    • On German (Volkswagen, BMW) - on the side member or cylinder block.
  • In the trunk under the rug (relevant for Skoda, Seat, Kia).
  • On frame (for SUVs and pickups, e.g. Ford Ranger or Toyota Hilux).
    • 💡

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

    For accuracy, use a flashlight and a magnifying glass - symbols may be worn out by corrosion or paint. On older cars (pre-2000), the VIN sometimes consists of 13 characters - this is normal, but you will have to check it through specialized services (for example, VinHistory).

    📊 Where do you usually check the VIN code when inspecting a car?
    On the windshield
    Under the hood
    On the sign in the doorway
    In PTS/STS

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

    The VIN code is divided into 3 parts, each of which carries specific information:

    Positions Title What does it mean Example
    1–3 WMI (World Manufacturer Identifier) Manufacturer and country code JTE — Toyota (Japan)
    4–8 VDS (Vehicle Descriptor Section) Model, body type, engine ZZ10R — Corolla with 1.8L engine
    9 Check digit Code authentication 5
    10 Year of manufacture Letter or number (see table below) L — 2020
    11 Manufacturing plant Specific plant (if the brand has several) 6 - plant in San Antonio (USA)
    12–17 Serial number Unique car number 123456

    The most important symbols for the buyer are: 10th (year of issue) and 4–8th (model and engine). For example, in VIN WAUZZZ4LZBD012345:

    • WAU — Audi (Germany).
    • ZZZ4L - model Audi A4 with 2.0 TFSI engine.
    • B — 2011.

    To decipher the year of manufacture, use this table (valid for cars after 2000):

    2000: Y  | 2005: 5  | 2010: A  | 2015: F  | 2020: L

    2001: 1  | 2006: 6  | 2011: B  | 2016: G  | 2021: M
    

    2002: 2  | 2007: 7  | 2012: C  | 2017: H  | 2022: N
    

    2003: 3  | 2008: 8  | 2013: D  | 2018: J  | 2023: P
    

    2004: 4  | 2009: 9  | 2014: E  | 2019: K  | 2026: R
    How to check check digit (9th character)

    This requires mathematical calculations using the ISO 3787 algorithm. To simplify this, use online calculators (for example, on the website VinDecoderz). If the check digit does not match, the VIN is fake!

    Common mistakes when checking VIN: how not to get scammed

    Even experienced buyers make mistakes that lead to the purchase of a problematic car. Here are the most dangerous:

    1. Only PTS is trusted:

      Documents may indicate one model (for example, Skoda Octavia), and the VIN determines another (Skoda Octavia RS). This is a sign relabeling - when a car was restored from several cars after an accident.

    2. Ignore check digit:

      If the 9th character does not match the calculation, the VIN is fake. You can check it on the website VinDecoderz.

    3. VIN is not checked for originality of the body:

      On American cars (for example, Ford Mustang or Chevrolet Camaro) they often fake the plate on the windshield, but forget about the code on the frame. Always check at least 2 sources!

    Another common trick of scammers is "cloning" VIN. Attackers take the code from a wrecked car and transfer it to a stolen car. You can check this:

    • 🔎 Comparing the VIN with the database of stolen cars (traffic police or Interpol).
    • 📸 Asking for a photo of the original plates (under the hood and in the trunk).
    💡

    If the seller refuses to provide the VIN for verification or offers “his own” reports, this is a reason to refuse the deal. The actual history of the vehicle is always independently verified!

    VIN code for selecting spare parts: how not to make a mistake with components

    When purchasing spare parts (especially for Japanese and Korean auto) VIN code helps to avoid compatibility errors. For example, at Hyundai Solaris 2017 and 2018 may differ:

    • 🔋 Engine ECU (different firmware).
    • 🚪 Tail lights (the shape has changed in restyling).
    • ⚙️ Gearbox (6-speed instead of 5-speed).

    How to use VIN for selection:

    1. Copy the code from the plate (not from the PTS!).
    2. Enter it in the manufacturer's catalog:
      • For Toyota/Lexus: Toyota Parts.
      • For Volkswagen/Audi: ErWin (requires registration).
  • Check the articles with the offers on Exist.ru or Autodoc.
    • ⚠️ Attention: On Chinese cars (Haval, Chery) VIN may not work in European catalogues. In this case, look for spare parts according to body number or article number of the original part.

    Example: for Kia Rio 2020 with VIN Z94CB41BBLR012345 the system will select the original filter 26300-1G000, while a model without a VIN can get the wrong part number 26300-1G100 (from restyling 2021).

    In Russia, the VIN code has legal force and is used:

    • 📋 When registration to the traffic police (checked with the PTS).
    • 🔍 When theft check (Ministry of Internal Affairs base).
    • 💰 When registration of compulsory motor liability insurance (insurance companies check accident history).

    New rules came into force in 2023:

    • 📌 Prohibition on changing VIN: Even with major body repairs, the code must remain original.
    • 🔧 Mandatory marking of units for cars older than 3 years when sold (Decree No. 1240 of 2022).

    If you are buying a car with broken VIN, it is not allowed:

    • ❌ Register with the traffic police.
    • ❌ Insure under OSAGO (insurance companies will refuse).
    • ❌ Sell officially (only by general power of attorney, which is risky).

    Exception - restoration cars (over 30 years old), for which it is permitted to produce a duplicate VIN in agreement with the traffic police.

    FAQ: Answers to frequently asked questions about the VIN code

    Is it possible to find out the original color of a car using the VIN?

    Yes, but not in all services. For example, VinHistory shows the factory color (paint code), and Autocode - only if it was changed during repainting. For accuracy, check the paint code on the sign in the doorway (for example, 3L5 - “metallic gray” Volkswagen).

    What to do if the VIN code is erased or unreadable?

    If the code is erased by 1-2 characters, try to restore it using logic (for example, the check digit can be calculated). If the VIN is not completely readable:

    1. Check other places (under the hood, in the trunk).
    2. Check with the PTS (but remember that documents can also be fake).
    3. Contact expert organization (for example, US) for identification.
    Important: If the VIN is intentionally erased (traces of grinding), refuse to purchase - this is a sign of a criminal history.
    Does the VIN indicate whether the car was in a taxi or car share?

    Directly - no, but there are indirect signs:

    • 📈 High mileage (for example, 300+ thousand km in 3 years).
    • 🔄 Frequent changes of owners (in the report CarVertical).
    • 🛠️ Traces of “commercial” use (worn seats, pedals).

    For accuracy, request an extract from the traffic police on the ownership history.

    Is it possible to find out from the VIN whether a car is damaged or not?

    Yes, but only if the accident was officially recorded (insurance payment, repairs at a service station). Services type Autocode show:

    • 🚨 Date and severity of the accident.
    • 💰 The amount of insurance payment.
    • 🔧 List of damaged parts (if there is data from the service).
    But: if the car was repaired “on the knee”, this will not be reflected in the report. Always inspect the car on a lift!
    What is a “clean” VIN and where can I check it?

    A “clean” VIN is a code that:

    • ✅ Not listed in the database of stolen cars.
    • ✅ Has no traffic police restrictions (arrest, bail).
    • ✅ Corresponds to the data in the PTS and on the body.

    You can check it for free:

    • On the website traffic police (section “Vehicle check”).
    • In service AVIN (theft database).
