The body number is a unique vehicle identifier that plays a key role when buying, selling, registering and repairing a car. Many car owners confuse it with VIN code, although in practice they are often the same thing. However, in some cases (especially on old or imported cars), the body number may differ from the VIN or duplicate part of it. Why is this important? Without the correct number, you will not be able to register the car, check its history, or even order spare parts.
In this article, we will look at where exactly to look for the body number on different car brands, how to read it correctly (including complex cases with corrosion or damage), what the numbers and letters in the code mean, and how to avoid fraud when buying a used car. You will also learn how the body number differs from chassis and engine, and why all three identifiers must match the documents.
If you are planning to buy a car second-hand, sell your car, or just want to understand the technical nuances, this information will save you time and money. For example, knowing the exact location of the body number will help you quickly check it for alterations - one of the most common ways to hide theft or an accident.
What is a body number and why is it needed?
The body number is a factory identifier that is assigned to a vehicle during production. It serves for:
- 🔹 Account registration in the traffic police and other government agencies. Without it, it is impossible to register or deregister the car.
- 🔹 Model identification and configurations. By the number you can determine the year of manufacture, country of assembly and even car options.
- 🔹 History checks. Using the body number (or VIN) you will find out whether the car has been stolen, accidented, pawned or loaned.
- 🔹 Selection of spare parts. Many details are tied specifically to the body, and not to the model as a whole.
On most modern cars, the body number matches the VIN code (or is part of it). However, on older machines (for example, Soviet VAZ-2106 or Moskvich-412) body number and VIN could be indicated separately. Differences are also found on some Japanese and American cars, where the body and chassis are registered as different units.
Important! In Russia, since 2011, the body number is officially equal to the VIN and must duplicate it. But in practice, traffic police inspectors may still require both identifiers to be indicated in documents, especially if the car is older than 10 years.
⚠️ Attention: If only the VIN is indicated in the PTS or STS, but the body number is missing, this is not always an error. On many foreign cars (for example, Toyota or Honda) the body and chassis are marked with the same code. But if the documents have both numbers, they must completely match those marked on the car.
Where is the body number located: typical places on different cars
Manufacturers place the chassis number in several standard locations, but their location may vary depending on the make and model. Here's where to look:
| Vehicle type | Body number location | Examples of models |
|---|---|---|
| Passenger cars (sedans, hatchbacks) | Under the hood (on the front panel), on the driver's door pillar, under the rear seat | VW Golf, Toyota Corolla, Lada Vesta |
| SUVs and crossovers | On the side member, under the plastic sill trim, on the frame (if there is one) | Nissan X-Trail, Kia Sportage, UAZ Patriot |
| Minibuses and commercial vehicles | On the front cross member, inside the cabin (under the trim), on the rear door | Gazelle Next, Ford Transit, Mercedes Sprinter |
| Old Soviet cars | On a plate under the hood, on the A-pillar, sometimes on the engine block | VAZ-2107, GAZ-24, ZAZ-968 |
On most foreign cars, the body number is duplicated in three places: on a plate under the hood, on the driver's door pillar and in a special window on the windshield (if there is one). On domestic cars (for example, Lada Granta or UAZ Hunter) the number is often marked only under the hood.
Advice: If you can’t find the number, check the vehicle’s technical passport (PTS) - it shows its exact location. On some machines (for example, BMW or Audi) the number may be hidden under plastic panels - they will have to be carefully removed.
How to correctly read the body number: problems and solutions
Sometimes the chassis number can be difficult to read due to corrosion, dirt or damage. Here's what to do in such cases:
- 🧹 Cleaning. Use a wire brush or solvent (such as WD-40) to remove rust. Do not use abrasive materials as they may erase the numbers.
- 🔦 Backlight. Take a flashlight and illuminate the room from different angles. Sometimes numbers are visible only under oblique light.
- 📸 Photo with enlargement. Take a photo of the number and enlarge the image on your phone - this will make it easier to make out the damaged characters.
- 🔍 Reconciliation with documents. If the number is partially erased, compare it with what is indicated on the PTS. Usually the first 3-5 characters are enough to recover the rest.
Warning: If the body number completely erased or clearly interrupted, this is a reason to refuse to buy a car. Even if the seller assures that “this happens,” the risk of running into a stolen or damaged car is too high.
What to do if the body number is interrupted?
If you find signs of interruption (uneven numbers, traces of putty, discrepancies with documents), stop the transaction immediately. A broken number is a 100% sign of fraud. Contact the traffic police to check the database of stolen cars. Don't believe the stories about "factory defects" or "restoration" - manufacturers never correct the numbers after the car is released.
On some vehicles (for example, Mercedes-Benz or Volvo) the body number may be laser engraved rather than embossed. In this case, it looks like a series of dots that are difficult to see without a magnifying glass. If in doubt, contact an authorized dealer - they have special scanners for reading such tags.
How to decipher the body number: structure and meaning of symbols
The body number (or VIN) consists of 17 characters (numbers and Latin letters, except I, O and Qto avoid confusion). Each symbol carries certain information:
- 1–3 characters (WMI). World manufacturer index. For example:
XTA— Toyota (Japan)WDB— Mercedes-Benz (Germany)XW8— Volkswagen (Russia, Kaluga)
21043 on VAZ-2104 indicates a station wagon with a 1.5 liter engine.A — 2010, L — 2020.Example of VIN code decoding XTA210430L1234567:
XTA- manufacturer Toyota (Japan)210430- model Corolla, sedan, 1.6 l engineL— 2020 year of manufacture1234567- serial number
Important! If the body number contains letters I, O or Q, this is a sure sign of a fake - they are never used in official VINs.
☑️ Body number authentication
What is the difference between a body number and a chassis and engine number?
Many people confuse these three identifiers, but they serve different purposes:
| ID | Purpose | Where indicated | Example |
|---|---|---|---|
| Body number (VIN) | Unique code for the entire vehicle | Under the hood, on the door pillar, in the vehicle title | XTA210430L1234567 |
| Chassis number | Frame ID (if any) | On the side members, under the bottom | JH4KA7660MC001234 |
| Engine number | Power unit marking | On the cylinder block | 5A-FE 1234567 |
On most passenger cars body and chassis numbers match (since the body acts as a supporting structure). However, on frame SUVs (for example, Toyota Land Cruiser 200 or Nissan Patrol) or trucks, the chassis number may vary.
Why is this important? When registering with the traffic police, the inspector checks all three numbers. If at least one of them does not match the documents, you will be denied registration. Also, mismatched numbers are a sign that the engine or body may have been replaced after an accident.
⚠️ Attention: On some vehicles (for example, Mitsubishi Pajero or SsangYong Actyon) the chassis number can be printed on a separate plate under the hood. If it is not there, this is not always a problem, but it is better to check with the dealer where the original number should be located.
How to check the body number before buying a car: step-by-step instructions
If you are buying a used car, checking the chassis number is a must. Here's how to do it right:
- Visual inspection. Find the body number on the car and compare it with what is indicated in the PTS and STS. All characters must match without exception.
- Check for interruption. Run your finger over the numbers - they should be smooth, without burrs. Use a magnifying glass if in doubt.
- Online check. Enter VIN on websites traffic police, Autocode or CarVerticalto find out the car’s history (thefts, accidents, restrictions).
- Reconciliation with the traffic police database. Ask the seller to provide an extract from the register of pledges (available at traffic police website).
What you should be wary of:
- 🚨 The body number is painted over or covered with dirt in unusual places.
- 🚨 The PTS and the car have different numbers (even if one digit is different).
- 🚨 The seller refuses to provide the original PTS or interferes with the inspection.
If you buy a car in another region, order an on-site inspection through the service Autocode or Carfax. A specialist will arrive with the equipment and check the body number for interruptions, and also diagnose hidden damage.
If you find any discrepancies, do not be lazy to go to the traffic police and make an official request. It's better to spend an extra day than to buy a problem car.
Frequently asked questions about body number
Is it possible to drive if the body number has been erased?
Technically, yes, but the first time you contact the traffic police (for example, to replace your license or sell a car), you will be refused service. The erased number must be restored through examination. To do this, contact a specialized center (for example, US) - they will issue a conclusion on the compliance of the number with the documents.
What to do if the body number does not match the title?
This is a serious problem. Possible reasons:
- Typo in documents (rare, but it happens).
- Number interruption (most often).
- Replacement of the body after an accident (must be formalized).
In any case, the problem cannot be solved without an examination and contacting the traffic police. If the car is registered, it can be removed for data discrepancies.
Where can I find the body number on an electric car?
On electric cars (for example, Tesla or Nissan Leaf) the body number is located in the same places as on regular cars: on the door pillar or under the hood (if there is one). On some models (for example, Tesla Model 3) VIN is also duplicated on the battery.
Is it possible to find out the color of a car by the body number?
No, the color information is not encrypted in the VIN code. However, some manufacturers (for example, BMW or Audi) indicate the color code on a separate plate under the hood. You can also find out the color by the VIN code through dealer services (for example, Etis for Ford).
Before buying a car, always check the body number for interruptions and compare it with the documents. Even a small discrepancy can mean that the car is stolen, has a loan, or has a hidden history of an accident.
