How to find out the car body number: all methods from documents to hidden marks

The body number is a unique identifier that is assigned to a vehicle at the manufacturer. It is needed not only for registration with the traffic police, but also for checking the history of the car, selecting spare parts or recovering from an accident. However, finding it is not always easy: on some models the number is stamped in hard-to-reach places, and the documents may contain an incomplete or encrypted code.

In this article we will look at all possible ways, how to find out the body number - from official documents to hidden factory marks. You will learn where to look for VIN and body number on foreign cars (from Toyota up to BMW) and domestic cars (from VAZ up to UAZ), how to decipher the code and what to do if the number is erased or missing. We will also explain how it differs VIN from body numbers and why both codes are important when buying a used car.

1. What is the difference between the body number and the VIN code?

Many people confuse these concepts, but they mean different things. VIN (Vehicle Identification Number) is an international vehicle identifier, which consists of 17 characters (numbers and Latin letters). It contains information about the manufacturer, model, year of manufacture and even the configuration of the car. For example, VIN Toyota Camry might look like this: JT2BF22KXW0123456.

But body number is a separate identifier that is assigned directly to the body part of the car. He can:

• 🔢 Match the last 6–9 characters of the VIN (for most modern cars).
• 🔢 Be completely code independent (for older machines or some brands, e.g. Mercedes-Benz).
• 🔢 Absent at all (for some commercial vehicles or motorcycles).

For example, at Volkswagen Passat B6 The body number usually duplicates the last 7 characters of the VIN, and VAZ-2107 This is a separate 6-digit code stamped on the A-pillar. Why is this important? When registering with the traffic police, you must indicate both numbers, and when checking for theft or arrest, you must check their compliance with the documents.

⚠️ Attention: If only the VIN is indicated in the PTS or STS, but the body number is missing, this does not always mean forgery. Some cars (for example, Ford Transit or Renault Master) the body number may not be assigned by the factory. But if the car is domestic or older than 2000, the lack of a license plate is a reason for additional verification.

2. Where can I look for the body number in the documents?

The easiest way to find out the body number is to look at the official documents for the car. It must be indicated in the following documents:

Document	Where to look for the body number	Notes
PTS (Vehicle Passport)	Line “Number (chassis, frame, body)” or “Body number”	If the line is empty, the number may match the last characters of the VIN
STS (Certificate of Registration)	Field “Body number (frame, chassis)” on the back side	In new STS (from 2020) there can only be a VIN
Sales and purchase agreement	Section “Vehicle identification data”	If the number is not specified, ask for it when completing the transaction.
OSAGO/CASCO insurance policy	In the “Vehicle Data” column or on the reverse side	Not all insurance companies provide the body number

If the body number is not specified in the documents, this is not always criminal. For example, at BMW X5 (E53) Before the 2006 model year, the body number was often absent from the title, but was stamped on the car. However, if you are buying a used car, The absence of a body number in the PTS when it is present on the car itself is a sign of possible alteration or forgery of documents.

What to do if documents are lost? You can request a duplicate PTS from the traffic police or use online verification services, for example, through the portal Public services or website Autocode. But for this you will need the VIN or license plate number of the car.

3. Where is the body number physically located on the car?

If the documents are not at hand or you want to check the number “live”, you need to look for it on the car itself. The location depends on the make, model and year of manufacture. Below we have collected most common places, where manufacturers place body numbers.

3.1. Foreign cars (Europe, USA, Japan, Korea)

For most foreign cars, the body number duplicates the last characters of the VIN and is located in the following areas:

• 🚗 Under the hood: on the A-pillar (usually on the driver's side), on the side member or on the partition between the engine compartment and the passenger compartment. Example: Audi A4, Volkswagen Golf.
• 🚗 At the door threshold: on the driver or passenger side, under the rubber seal. Example: Toyota Corolla, Hyundai Solaris.
• 🚗 In the trunk: under the carpet, on the rear pillar or wheel arch. Example: Skoda Octavia, Kia Rio.
• 🚗 On the windshield: in the lower corner on the driver's side (often matches the VIN). Example: Ford Focus, Renault Duster.

Some premium brands (for example, Mercedes-Benz or BMW) the body number can be stamped on a special plate under the hood or in the glove compartment. It is also sometimes duplicated on paint data plate (usually in the trunk or on the door pillar).

3.2. Domestic cars (VAZ, GAZ, UAZ)

For Russian cars, the body number is most often located in the following places:

• 🚘 On the front pillar: on the driver's side, under the hood (for example, VAZ-2110, Lada Granta).
• 🚘 On the floor under the driver's seat: you need to move the rug and look for the embossed markings (typical for GAZelle or UAZ Patriot).
• 🚘 On the rear wheel arch: in the trunk, under the trim (for example, VAZ-2107, Niva 4x4).
• 🚘 On the machine data plate: usually riveted to the body in the engine compartment (for example, VAZ-2114).

In old Soviet cars (for example, Moskvich-412 or ZAZ-968) the body number could be stamped on frame or even on engine. If the car underwent a major overhaul, the number could be transferred to a new part, which today is considered a violation.

4. How to decipher the body number?

The body number, unlike the VIN, does not have a uniform decoding standard. However, most manufacturers have their own principles for generating code. For example:

• 🔢 First 3–4 characters often denotes the model or series of a car. For example, at Toyota code JT2 could mean Camry, and JT4 — RAV4.
• 🔢 Next 2–3 characters - year of manufacture or manufacturer. For example, at Volkswagen letter W may indicate a plant in Wolfsburg.
• 🔢 Last 6–8 characters — a unique serial number of a specific vehicle.

Some manufacturers use the body number check digits for authentication. For example, at BMW The last digit of the body number must match the check digit in the VIN. If they do not converge, this may indicate interruption.

To decrypt, you can use:

• 📱 Online services: VINformer.su, Autocod.ru (enter VIN or body number).
• 📖 Manufacturer's reference books: for example, directories ETKA for Volkswagen Group.
• 🔧 Dealer centers: they can provide an official transcript upon request.

⚠️ Attention: If, when checking through the online service, the data on the VIN and body number do not match (for example, year of manufacture or model), this may mean that the car is assembled from different parts or the number is altered. It is better not to buy such a car without a thorough examination.

An example of decoding the body number of Toyota Corolla E120

Body number: AXE10-1234567

• AXE10 - model Corolla sedan, 1.6 l, front-wheel drive.
• 1 - plant in Japan (Tahara Plant).
• 234567 — car serial number.

This decoding can be clarified at the dealership or through specialized databases.

5. What should I do if the body number is erased or missing?

Situations where the body number is unreadable or missing occur frequently. The reasons may be different:

• 🔧 Corrosion or mechanical damage (for example, after an accident).
• 🔧 Number interruption (criminal or after body restoration).
• 🔧 Factory defect (rarely, but happens with budget models).

If the number is erased, but its outline is visible, you can try:

• 🕵️ Treat the surface with a special composition for restoring engraving (sold in car dealerships).
• 🕵️ Use an ultraviolet lamp - sometimes the number appears under UV rays.
• 🕵️ Take photos of the place from different angles and enlarge the image on your computer.

If the number is missing completely, you will need:

1. 📋 Contact the traffic police with a request for data recovery. Documents for the car and examination will be required.
2. 🔍 Conduct a forensic examination (if there is a suspicion of interruption). Cost - from 5,000 rubles.
3. 🚗 Check VIN with manufacturer's database — sometimes you can use it to restore the body number.

⚠️ Attention: If you buy a car with an illegible or missing chassis number, The traffic police may refuse registration until an examination is carried out. In addition, such cars often end up stolen or with a “problematic” history. It's not worth the risk - it's better to choose another option.

6. How to check the authenticity of the body number?

Replacing the body number is one of the most common schemes used by scammers when selling stolen or damaged cars. To avoid becoming a victim of fraud, check:

6.1. Visual signs of interruption

• 🔎 Jagged edges of characters — factory engraving is always clear.
• 🔎 Traces of putty or paint around the room.
• 🔎 Different font or character depth (for example, some numbers stand out more strongly).
• 🔎 Presence of microcracks around the number (a sign of mechanical impact).

6.2. Checking through databases

Check the body number and VIN through official services:

• 📊 GIBDD.RF — check for theft, arrests and restrictions.
• 📊 Autocode.RF — ownership history, accidents, mileage.
• 📊 VIN.ua — data on the configuration and original parts.

If the VIN and body number data do not match (for example, different years of manufacture or model), this 100% sign of fraud. You should also be wary if:

• 🚨 In the PTS, the body number is entered by hand (must be printed).
• 🚨 The seller refuses to provide the car for inspection during the daytime.
• 🚨 The body number on the car and in the documents differs even by one character.

7. Frequently asked questions about the body number

Is it possible to drive if the body number has been erased?

Yes, but the first time you contact the traffic police (for example, to replace your license or re-register), you will need to restore the number. Otherwise, registration actions may be refused.

What to do if the body number does not match the title?

Stop the deal immediately! A discrepancy in numbers is a sign of alterations, forgery of documents, or the fact that the car was assembled from different cars (“constructor”). Contact the traffic police for verification.

Where can I find the body number on a motorcycle?

On motorcycles, the body (or frame) number is usually stamped on the steering column, under the seat, or on the rear of the frame. For some models (for example, Yamaha or Honda) it is duplicated on the VIN plate.

Is it possible to find out the owner by the body number?

No, this information is confidential. However, by using the body number or VIN you can find out the history of the car: number of owners, accidents, mileage (through services like Autocode or CarVertical).

What is a “duplicate body number”?

This is a copy of the original number applied to the body after restoration (for example, after an accident). This practice is permitted only by official service centers with the permission of the traffic police. Self-duplication of numbers is prohibited!
