Finding a vehicle identification number often becomes necessary at the most inopportune times: when applying for insurance, purchasing spare parts, or checking the legal purity of a car before a transaction. Many drivers do not look under the hood or into doorways for years, relying only on data in documents, but knowing the exact location VIN code can save you from buying a stolen car or help you quickly find the right parts in catalogs.
Body number, which is technically more correct to call VIN (Vehicle Identification Number), is a unique 17-digit code containing information about the manufacturer, year of manufacture, model and specific configuration of the machine. The location of this code is strictly regulated by international standards, but manufacturers often duplicate it in several places for convenience and additional protection against theft, so the search can take from a couple of seconds to several minutes depending on the brand.
In this article, we'll take a closer look at all the possible locations for identification marks, learn how to read nameplates, and discuss what to do if the number is damaged by corrosion or hidden by dirt, so you can always quickly access this critical information.
Primary location: where to look first
The fastest and most obvious way to find out the body number is to inspect a special metal plate or sticker located in the driver’s line of sight. In the vast majority of modern cars manufactured after 2000, this identification plate It is mounted on the central pillar of the body on the driver's door side. It is enough just to open the door and look down at the end of the rack, where information about permissible axle loads and the production date is usually located.
However, you should not limit yourself to just this place, as the data may be duplicated. The second most popular location is the area under the windshield on the driver's side. The number can be embossed directly onto the metal dashboard panel or applied to a special plate that is visible through the glass from the outside of the car. This is done so that the inspector can count VIN codewithout opening the door or disturbing the owner.
In some models, especially the premium segment or specific brands, the location may be non-standard. For example, on a number of BMW or Mercedes cars, the number may be stamped on the shock absorber “glass”, which is visible when the hood is open, or even in the battery niche. Always check the technical documentation if standard places do not give results.
- 🚗 The central pillar of the body (the end of the driver's door) is the most common place for the sticker.
- 🔍 The lower part of the windshield (left) - visible from the outside, often embossed on the metal.
- 📄 Technical passport (PTS/STS) is the main document where the code is always indicated exactly.
- 🧾 OSAGO/CASCO insurance policy - contains duplicate information for verification.
⚠️ Warning: Never rely on just one sign. Attackers can replace an easily accessible sticker on the door, but the original markings on the frame or under the hood will remain intact. Always check all available tags.
⚠️ Attention: If you find that the plate on the door pillar comes off easily or has traces of re-sticking, this is an alarming sign that the license plates may be interrupted or the vehicle may be stolen.
Hidden and duplicate markings under the hood
The engine compartment is the second front of work for those who are looking for serial number. Manufacturers often place duplicate markings here, embossed directly on the metal of the body, which makes it more resistant to external influences compared to stickers. Most often you should look on the top of the front side members, on the “cups” of the shock absorber struts, or on the partition between the engine and the passenger compartment.
For body-on-frame vehicles such as SUVs Toyota Land Cruiser, Nissan Patrol or pickup trucks, the bed number is often stamped on the frame itself. Getting to it can be difficult: sometimes you need to remove the plastic protection, the mudguard, or even dismantle the battery. On older cars, this area may be hidden under a layer of dirt and oil deposits, so a thorough cleaning with a rag and degreaser will be required.
It is important to distinguish the body number from the engine number. Although in some older cars they may have been the same or had a similar structure, modern VIN code refers specifically to the body (or frame), and the engine has its own, separate number. Confusion here is unacceptable, since when registering with the traffic police or passing a technical inspection, it is the body identifier that is verified.
Use wet windshield wipes or a special aerosol carburetor cleaner to quickly clean the engine compartment of oil and dirt without damaging the metal.
The difficulty of searching under the hood often lies in poor lighting and cramped spaces. In such cases, a powerful flashlight and a small mirror will be an indispensable assistant, which will allow you to see numbers in hard-to-reach places without disassembling half the car. If the number is deeply stamped and covered with anti-corrosion, carefully use a soft brush so as not to damage the notches.

Features of VIN search on different car brands
Each automaker has its own established traditions and standards for placing identification data, which can significantly complicate the search for an inexperienced owner. For example, a German concern Volkswagen Group (including Audi, Skoda, Porsche) traditionally places the main plate in the trunk. To find the number, you need to lift the luggage compartment floor and look in the spare wheel well or under the carpet, where the code will be stamped into the metal.
American cars such as Ford, Chevrolet or Jeep, often follow the standard of placement on the dashboard (dashboard) under the windshield, visible from the outside. However, a duplicate number can be hidden in the driver's wheel arch or on the side member. French stamps Renault and Peugeot they like to hide the number in the doorway, but not on the counter, but on the threshold or even in the area where the seat belts are fastened, which requires a careful inspection of the entire perimeter of the cabin.
Japanese manufacturers are more conservative and predictable in this regard: most often the number is stamped on the shock absorber cup or on the partition of the engine compartment, and a duplicate sticker is located on the door pillar. However, on domestic market (JDM) models, markings may be in Japanese characters, requiring the use of a translator or reference book.
Why do some cars have two body numbers?
There are cases when a car has two VIN codes. This is typical for cars assembled from large components (CKD), or for cars that have undergone major repairs with body replacement. In such cases, one number is from the original body, the second is from the new element, and both must be included in the documents.
Below is a table to help you navigate the main search locations for popular brands, but remember that the location may vary depending on the year of manufacture and the specific model.
| Car make | Main location | Duplicate markings | Features |
|---|---|---|---|
| Volkswagen, Audi, Skoda | Trunk (under floor/mat) | Door pillar / PTS | It is often necessary to lift a heavy trunk floor |
| Toyota, Lexus | Driver's door pillar | Engine compartment (glass) | The number on the glass is often filled with anticorrosive agent |
| BMW, Mercedes | Door pillar / Under windshield | Dashboard / Side member | On older models it may be on the engine panel |
| Ford, Chevrolet | Under the windshield (left) | Wheel arch/spar | Clearly visible from the outside, convenient for inspection |
| Lada (VAZ) | Interior floor (under the carpet) | Door pillar / Engine shield | Often suffers from corrosion and requires cleaning |
Readability Issues: Corrosion and Damage
One of the most common problems when searching body numbers is its poor readability. Metal plates, especially those located on the thresholds or in the trunk, are subject to constant exposure to moisture, reagents and mechanical friction from shoes or loads. Over time, the paint swells, the metal becomes covered with rust, and the numbers become indistinguishable, which can create serious problems when selling a car or registering it.
If you encounter corrosion, do not rush to use aggressive chemicals or sandpaper, as this can damage the deep notches of the symbols, making the number completely unreadable. It is best to carefully remove loose rust with a soft brush, rinse the area with water and dry. For temporary contrast, you can use chalk or a special metal marker to fill in the indentations and make the numbers visible.
In cases where the number is critically damaged (through corrosion, mechanical destruction of symbols), a special examination will be required. A forensic expert using chemical reagents or a microscope will be able to restore the sequence of signs if they were not completely destroyed. This is an expensive and time-consuming procedure, so the condition of the marking areas must be monitored regularly.
Timely treatment of the areas where the VIN code is applied with anticorrosive or protective varnish (without painting over the numbers themselves) will extend their life and maintain readability for many years.
Particular attention should be paid to cars that have been in an accident. If the side member or part of the body where the number is written has been changed, the new element may not have a marking. In this case, the law requires maintaining the old number (transfer) or conducting an examination with changes to the documents. Driving with an unreadable number without the corresponding marks in the PTS may lead to a ban on registration.
Legal aspects and database verification
Understanding where it is VIN code, is only half the battle. It is much more important to be able to correctly interpret the information received and check its legitimacy. The body number is the key to the car's history. By entering these 17 characters into specialized services (for example, traffic police databases, Autotek or CarVertical), you can find out about the number of owners, participation in road accidents, use in a taxi and the presence of restrictions on registration.
Legislation strictly regulates labeling requirements. According to technical regulations, the number must be applied in a way that excludes the possibility of changing it without compromising its integrity. Any traces of welding, overcooked numbers or “porridge” instead of symbols is a direct path to refusal to register and place the car in a special parking lot until the circumstances are clarified.
When buying a used car, checking the vehicle registration number with the documents is a mandatory safety ritual. An error in even one number can mean that you have a “double” of a stolen car whose documents have been altered. Carefully check each letter and number, especially those that are easy to confuse: 0 (zero) and O (letter), 1 (one) and I (letter), 5 and S, 8 and B.
- ✅ Always check the VIN in the PTS, STS and on the body - all three sources must match perfectly.
- ✅ Check the car history by VIN before transferring money to the seller.
- ✅ Pay attention to the font width and embossing depth - they must be factory settings.
- ✅ Take photographs of the body number at each inspection to create an archive of the condition.
⚠️ Attention: If, when inspecting the car, you find that the body number is painted over, filled with sealant or hidden under a layer of sound insulation, this is a reason to immediately terminate the transaction and leave. Such manipulations almost always indicate the car’s criminal past.
What to do if the body number does not match the documents
The situation when the number found on the body does not match the data in the PTS is critical. This may be the result of a simple mistake by a traffic police officer when entering data, the result of a body replacement (for example, after a total accident), or a sign of fraud. In any case, the operation of such a vehicle is prohibited until all circumstances are clarified and appropriate changes are made to the registration data.
If you are the owner of such a car and know about the legality of the replacement (for example, the body was officially changed at the dealer), you need to collect all the certificates, certificates of work performed and contact the traffic police to make changes. The procedure will require an inspection of the vehicle by a forensic expert who will confirm that the number on the new body matches the documents for the unit.
If you buy a car with mismatched license plates second-hand, you can only return it through the court, declaring the transaction invalid. However, it is easier and safer to be careful during the pre-check phase. Use online services for decryption VIN code, to make sure that the model, year and equipment coded in the number match what you see in front of you.
Is it possible to drive if the body number is not readable?
You can drive, but only to the first traffic police post or attempt to sell the car. When stopped, the inspector has the right to send the car for examination and detain it until clarification. It is better to undergo an examination in advance and obtain a conclusion on the preservation of the marking.
Remember that the body number is not just a set of numbers, but a “passport” of your car. Taking care of where you apply it, checking it regularly, and knowing where it is located will help you avoid many legal and technical problems in the future. Always keep this information under control and your vehicle will be safe.
Frequently asked questions (FAQ)
What to do if the body number is completely rotten?
If the body number has completely rotted, it is necessary to undergo a restoration examination procedure. The expert will determine the fact of destruction of the markings and issue a conclusion. With this document and the conclusion on the assignment of a new identification number (or maintaining the old one, if possible), you need to contact the traffic police to make changes to the PTS and issue a new STS.
Where is the VIN code for cars without a frame?
For cars with a monocoque body (most passenger cars), the number is stamped directly on the body elements: on the shock absorber, on the partition of the engine compartment, on the floor under the feet of the driver or passenger, as well as on the central door pillar. The exact location depends on the make and model.
Is it possible to remove rust from the body number yourself?
It is possible and necessary to carefully clean the surface from loose rust and dirt. However, it is strictly forbidden to use metal brushes, sandpaper or chemical compounds that corrode metal. You may damage the notches of the characters, which will make the number unreadable and lead to problems during registration.
How many digits are there in the body number?
The standard international VIN code consists of 17 characters (numbers and Latin letters). This code encrypts information about the country of origin, plant, model, body type, engine and year of manufacture. The letters I, O, Q are not used in the VIN code to avoid confusion with the numbers 1 and 0.
Why is the body number duplicated in different places?
Duplicating the body number in several hidden and open places is a measure of protection against theft and illegal modification. If criminals convert one location, the original number will be stored in another, allowing the vehicle to be identified and returned to its rightful owner.
