Buying a used car always involves certain risks, because unscrupulous sellers often hide the actual mileage, participation in an accident, or the presence of legal restrictions. That is why checking a car by VIN code has become a mandatory step before concluding a deal, allowing you to look into the car’s past and avoid buying a problematic vehicle. Modern online services and traffic police databases make it possible to obtain comprehensive information in a matter of minutes, without leaving home.
In this article we will look in detail where exactly to look VIN code, how to decipher it correctly and what hidden problems it can reveal. You will learn about free government resources and paid aggregators that collect data from insurance companies and service centers. A competent approach to analyzing a car’s history is your main tool in price negotiations and a guarantee of safety on the road.
Where to find the VIN number and how to read it
The first step to obtaining information about a car is to locate the ID itself. VIN code (Vehicle Identification Number) is a unique 17-digit number assigned by the manufacturer to each specific vehicle during assembly. Most often, it is stamped on a metal plate that is attached to the body in the engine compartment, on the driver's door pillar or at the bottom of the windshield. Also, a duplicate number must be contained in PTS (vehicle passport) and registration certificate.
When inspecting a vehicle in person, it is critical to check the license plates in all accessible locations. If the plate under the hood looks suspiciously new, has traces of glue, or the numbers are stamped at different depths and angles, this is a sure sign of broken numbers. It is also worth paying attention to the condition of the metal around the embossed code: lack of factory paint or traces of welding may indicate body repair or replacement of units.
The structure of the VIN code is not random and is divided into three semantic parts that help identify the origin of the car. The first three characters (WMI) indicate the country of manufacture and plant, the next six (VDS) describe the model, body type and engine, and the last eight (VIS) contain information about the year of manufacture and serial number. Knowing these features, you can easily identify the discrepancy between the declared configuration and the real state of affairs.
Particular attention should be paid to signs that can be easily counterfeited or altered by fraudsters. For example, in some cases numbers may be replaced by similar letters, so carefully check each letter and number, especially those that are visually similar to each other. For an accurate check, use a magnifying glass or phone flashlight to examine the bottom of the characters for sanding marks.
Take a close-up photo of the VIN plate when inspecting the car - this will help you compare house numbers in a calm environment using various databases.
Free check through official traffic police databases
The most reliable and free source of information about the legal purity of a car is the official website of the State Traffic Inspectorate. Here you can obtain information about vehicle registration, participation in road accidents and the presence of restrictions on registration actions. To get started, you need to go to the portal, select the “Services” section and enter the 17-digit body code in the appropriate request field.
The results of the check in the traffic police database allow you to find out whether the car is in wanted or pledged to the bank. If the car has a registration ban, you will not be able to register it until the previous owner resolves his problems with the law or creditors. The system will also show the ownership history: if the car often changed owners or was registered with legal entities (taxi, car sharing), this is a reason to think about its technical condition.
It is important to consider that the data in the database is not updated instantly, but with a slight delay, so fresh fines or newly issued restrictions may not yet be displayed. In addition, the service will not show the technical condition, actual mileage or quality of repair work performed. To get a complete picture, it is recommended to combine traffic police data with other sources of information.
- 🚔 Registration history: will show all previous owners and ownership periods.
- 🚫 Limitations: information about prohibitions on registration actions due to debts or fines.
- 🚓 Wanted: checking stolen cars and cars with altered license plates.
- 💥 Road accident: data on participation in accidents indicating the date and type of damage.

Paid aggregators and commercial reports
Unlike government resources, commercial aggregator services collect information from many sources, including databases of insurance companies, service centers, pawn shops and customs authorities. Reports from such platforms often contain data that cannot be found for free: real mileage recorded during each service call, photographs from accident scenes and details of insurance claims. The cost of such a report is usually offset by the opportunity to avoid buying a “damaged” or “twisted” car.
One of the key benefits of paid verification is the ability to see calculation of repair work for insurance cases. The document will indicate the parts replaced and the payment amount, which allows you to understand the extent of the damage. For example, if the report indicates replacement of the side member or airbags, but the car looks perfect on the outside, the seller was clearly trying to hide the consequences of a serious accident.
You can also check through commercial databases whether the car was used as taxi or a training vehicle, even if this is not indicated in the title. Such machines have enormous wear on the engine and transmission, which significantly reduces their further service life. Aggregators also check the VIN for use as collateral, which protects the buyer from the risk of the car being repossessed by the bank.
⚠️ Attention: Some scammers may create fake aggregator sites that charge money for the report, but send random information. Use only proven services with a good reputation and a lot of positive reviews.
Decoding of equipment and technical data
Knowing the VIN code, you can turn to specialized decoders or official manufacturer catalogs (for example, BMW ETK, Toyota EPC) to find out the exact factory configuration of the machine. This is especially true when purchasing premium cars, where the list of options can significantly affect the cost. You can make sure that the elements installed on the body (panoramic roof, leather interior, multimedia) are factory-installed and not added later.
The discrepancy between the actual configuration and the decoder data may indicate that the car was assembled from several damaged cars (the so-called “constructor”) or went through serious body repairs with the replacement of elements. For example, if the VIN code indicates a basic version without climate control, but the car has it, it is worth checking the quality of the electrical system and the integrity of the wiring.
Technical data also includes information about the engine type, its power and environmental class. This is important for the correct selection of spare parts and oils, as well as for understanding whether the car meets the requirements for entry into certain areas of the city. The table below provides examples of what information can be obtained from the different parts of the VIN.
| VIN part | Purpose | Example data |
|---|---|---|
| 1-3 characters (WMI) | Manufacturer ID | XWF (Russia, AvtoVAZ) |
| 4-9 character (VDS) | Description of model and characteristics | Body type, engine, belts |
| 10 character | Model year | L (2020), M (2021) |
| 11 character | Assembly plant code | Specific assembly plant |
| 12-17 character (VIS) | Production serial number | Unique car number |
What does the 10th character of the VIN hide?
The tenth character indicates the model year. However, the letters in this place are not in alphabetical order and have omissions (for example, the letters I, O, Q, U, Z, 0 are not used) to avoid confusion with numbers.
Hidden problems: twisted mileage and taxi
One of the most common problems in the used car market is misleading mileage. Sellers reduce odometer readings to increase the car's marketability, but it is almost impossible to hide the real numbers in electronic databases. With every diagnostic, scheduled maintenance or warranty call, the technician records the current mileage in the service book or dealer database, creating a digital history that cannot be erased.
Commercial reports often show a graph of changes in mileage: if in 2018 there were 150,000 km, and in 2019 it suddenly became 90,000 km, then there is evidence of interference with instrument readings. Machines with such manipulations require increased attention to the life of the engine and transmission, since their actual output can be close to critical. Buying such a car means you risk getting into expensive major repairs in the near future.
Another hidden threat is working in a taxi or car sharing. Such cars are operated 24/7 with many drivers who do not spare the equipment. Externally, the car can be put in order, repainted and the interior reupholstered, but the technical condition of the components and assemblies will be depressing. Checking taxi databases and analyzing the frequency of changes of owners (more than 3-4 times a year) help identify such “killed” candidates.
A crooked mileage is not just a hoax, it is a direct indicator that the life of the engine and gearbox is coming to an end, which means you will face big expenses.
Legal risks: liens, fines and scrap
Buying a car that is pledged to a bank risks losing money and the vehicle itself. If the previous owner stops paying the loan, the bank has every right to repossess the car, even if you bought it from an honest reseller. Checking the register of pledges (for example, on the notary’s website) and in the databases of commercial services helps protect yourself from such a situation. The absence of an entry in the registry does not provide a 100% guarantee, but it significantly reduces the risks.
It is also worth checking the car for unpaid fines that hang on the car, and not on the driver. Although by law the new owner is not required to pay fines to the previous owner, the presence of debts can create problems when registering. A traffic police officer may refuse registration until the debt is paid off, which will lead to unnecessary legwork and hassle.
The recycling status deserves special attention. If a car has been officially disposed of (scrapped), it is almost impossible to restore its registration. Some unscrupulous sellers try to sell such cars “for spare parts”, passing them off as whole. Checking the status in the traffic police database will show whether the car is registered as “recycled”.
⚠️ Attention: Never agree to a deal if the seller refuses to provide the original PTS, claiming that it is “in the bank” or “lost”. The absence of a key document is a red flag indicating possible legal problems.
Is it possible to check a car by license plate number?
It is impossible to check the ownership history or accidents directly by the number - you need the VIN. However, using the number, you can find the owner through tow truck databases or find out if the car is wanted through open sources, and then request the VIN from him for an in-depth check.
Frequently asked questions (FAQ)
Is it possible to check a car by VIN code for free and completely?
There is no completely free check that will show the entire history (accidents, liens, mileage). Only basic data is available for free on the traffic police website (restrictions, search, registration history). Detailed information is collected by paid aggregators from many sources.
What to do if the report shows accidents that never happened?
Sometimes databases contain errors or combine data from different cars with similar numbers. If you are sure that the car is clean, ask the seller to provide certificates from the insurance company or work orders from the service station confirming the nature of the damage (for example, a bumper scratch instead of a blow to the side member).
How to check a Japanese car without a VIN code?
Japanese cars produced for the domestic market often do not have the classic 17-digit VIN code, but instead use a Frame No. To check them, specialized auction sheets are used, which can be found by lot number or body number on aggregator sites.
Is a car that has been in an accident dangerous?
Not all accidents are critical. Light impacts to the bumper or replacement of a headlight cannot be considered fatal. Damage to the power structure of the body (spars, pillars, roof) is dangerous, as they violate the geometry and safety in subsequent accidents. Always look at the nature of the damage in the report.
