Car owners and used appliance buyers often face confusion in terms when it comes to vehicle identification. VIN code Vehicle Identification Number is the main identifier of the car worldwide, but in many documents, especially in the post-Soviet countries, the concept of body number still appears. This creates confusion, as for some cars these figures are the same, and for others – radically different.
Understanding how to count data correctly and where to look for them is critical when issuing an insurance policy, passing a technical inspection or buying spare parts. An error even in one digit can lead to a refusal to register a vehicle with the traffic police or problems with customs. In this article, we will discuss in detail what the difference between these concepts lies and how to correctly obtain the necessary information.
What is the difference between VIN and body number
Many motorists mistakenly believe that VIN code And the body number is the same thing. In fact, that's not always the case. VIN is a 17-digit alphanumeric code assigned to the manufacturer and contains information about the manufacturer, model, year of production and configuration. It is unique for each particular instance of the car.
Body number is usually part of the VIN code or a separate marking mark, which is applied directly to the bearing elements of the structure (sparters, glasses, partitions). In modern foreign cars, especially Japanese, Korean and European production, a separate body number often does not exist, and in the documents in this column rewritten the full body number. VIN.
The situation is complicated by the fact that different countries have different labeling standards. For example, cars manufactured in Japan for the domestic market may have a short chassis number that does not match the international 17-digit system. In such cases, when registering in the Russian Federation or other EAEU countries, additional examination is carried out to establish compliance.
⚠️ Attention: Never try to “calculate” the body number yourself by simply cutting off a portion of the VIN code if the car documents have different values. This can lead to legal errors when filling out the sales contracts.
It is also worth noting that the term “body number” historically developed when the frame and body were separate elements. Now that most cars have a load-bearing body, this border has been erased, but the bureaucracy continues to use outdated terminology along with modern ones.
Where to find identification numbers on the car
Finding labels is the first step to identification. Manufacturers place information in multiple locations for convenience and protection against theft. Principal location VIN code. It is a metal plate attached to the body. Most often it is in the engine compartment, on a glass of the front pillar or on the upper cross of the radiator.
Duplicate plate is often located in the opening of the driver's door, on the central pillar of the body. The same is usually the information on the permissible loads on the axles and the recommended pressure in the tyres. Some manufacturers, such as BMW or Mercedes-BenzThey can also apply the code under the front passenger mat or in the trunk under the flooring.
Separately, it is worth mentioning the numbers knocked directly on the metal. They can be on the spanger under the hood, on the partition of the engine compartment or even under the bottom of the car (often hidden by a hatch). These knocked-out signs are harder to forge, but they are more prone to corrosion and mechanical damage.
- 📍 Under the hood space: plaque on a splasher or glass of rack.
- 🚪 Doorway: sticker or riveted plaque on the central rack.
- 📄 Documents: PTS, CTS, service book and contract of sale.
- 🪟 Windshield: For many brands (Toyota, Ford), VIN is duplicated at the bottom of the glass on the left.
If you can’t find the number visually, it is worth looking into the technical documentation. In electronic PTS (EPTS), all data are clearly indicated. Also, the code is often specified in the insurance policy, although there are also sometimes typos that must be checked when receiving the document.
Structure and decoding of VIN code
To understand where in the code hides information about the body, you need to understand its structure. VIN code It consists of three main sections: WMI, VDS and VIS. The first three characters (WMI) are the country and the manufacturer. The following six (VDS) describe the model, body type, engine and safety system.
The last eight characters (VIS) contain information about the year of production and the number of the car. It is the last 6-8 characters that are often perceived as the “body number” in the simplified sense, since they are unique to a particular unit of production on the conveyor. However, the entire 17-digit code is legally relevant.
Different manufacturers use different coding systems. For example, Toyota and Lexus The 11th character often indicates the assembly plant, and the Ford - for the model year. European manufacturers (VAG Group, Renault) also have their own characteristics in the arrangement of body type and colour data.
What are WMI, VDS and VIS?
WMI (World Manufacturer Identifier) – the first 3 characters, indicate the manufacturer. VDS (Vehicle Descriptor Section) – signs 4–9, describe the characteristics of the car. VIS (Vehicle Identifier Section) – 10–17 signs, containing the year of issue and the serial number.
| Code segment | Symbolic positions | What does it mean? | Example |
|---|---|---|---|
| WMI | 1–3 | Manufacturer and country | XW1 (Russia, Kia) |
| VDS | 4–9 | Model, body type, ICE | C3 (sedan, 1.6 litres) |
| VIS | 10–17 | Year of release, serial number | P123456 (2023) |
| Control | 9 | Authentication | Number 0-9 or X |
It is important to understand that there is no single database that will give you a “body number” separately from the VIN at the click of your fingers, unless the manufacturer has laid such a logic. In most cases, either a full VIN or its latest signs are used to fill out documents, but only if this is expressly permitted by the regulations of the specific department.
Methods of checking the car by number
Checking the history of the car is a mandatory step before buying. Known. VIN codeYou can get detailed information about the past of the car. Official sources, such as the traffic police website or the register of pledges, provide data on registration, participation in an accident and the presence of restrictions.
Commercial services aggregate data from a variety of databases, including insurance companies, taxi services and repair shops. They allow you to see if the mileage was twisted, if the car was used in the taxi, and if it has unpaid fines. This is especially true for vehicles imported from abroad.
When checking, pay attention to the conformity of the marking marks. If the traffic police database indicates one VIN, and on the plate under the hood knocked out another (or there are traces of welding and corrosion at the site of application), this is a red flag. Also check the year of release in VIN with the actual condition of the cabin and body.
- 🔍 Official bases: traffic police website, register of pledges (PNP), FSSP website.
- 📱 Mobile applications: services for checking cars by VIN (Autocode, ProAuto, etc.).
- 🌐 International bases: CarVertical, AutoDNA (for imported cars)
- 👮 Police request: If you suspect theft or forgery of documents.
⚠️ Attention: Be careful with free VIN checkout services. They may collect your request and use the data to create duplicate documents or other fraudulent schemes. Use only the verified areas.
Registration problems and legal aspects
The most common problem arises when registering Japanese cars at auctions. The auction list may contain a short body number that does not match the 17-digit VIN, stamped on the frame or in the manufacturer's documents. In the PTS at the same time in the column "Body number" enter a full VIN, and in the column "Model TS" - data from the certificate of safety of the structure (SBKTS).
If the documents made an error, the traffic police inspector will refuse to register. Correction of errors requires contacting the forensic center (ECC) for identification examination. The expert will confirm that the numbers are not interrupted and correspond to each other, after which he will issue a conclusion for the traffic police.
Another problem is the corrosion of license plates. If the pad is knocked out VIN or the number of the body rotted, will require a complex recovery procedure. In some cases, the site is allowed to be digested, but only after the permission of the inspector and with the fixation of the process. Unauthorized actions will lead to a ban on registration.

How to find out the body number through online services
In the digital age, information has become easier to obtain. Many dealerships and official manufacturers’ websites offer VIN decoding services. Entering the code in a special field on the site BMW, Toyota or VolkswagenYou will get a detailed specification of the car, including the factory body number if it differs from the VIN.
There are specialized spare parts catalogs (e.g. Exist, Autodoc, TecDoc) that also use VINs to match parts. In their databases, you can often see the field “Frame No” or “Chassis No”, which is the body number for specific models. This is useful if you need to order a body part.
However, it is worth remembering that online services are not legally significant sources. The data obtained through the Internet are of reference nature. For official procedures (insurance, registration) use only the data specified in paper or electronic documents for the car (PTS, CTS).
When ordering VIN parts, always check with the manager whether they need a full 17-digit code or a body number (the last 6-8 characters) is sufficient, as in some databases these fields are separated.
Online services are convenient for quick receipt of reference, but only data from official documents (PTS, CTS) and the results of expert opinion have legal force.
Frequently Asked Questions (FAQ)
Can I find out the number of the body, knowing only the state number of the car?
Directly through open source free sources, no. The state number and VIN are tied to the traffic police databases, but access to this information is limited. However, there are paid services that can break through the history of the car and show VIN, and already by VIN you can try to find the body number through catalogs or documentation.
What if the body number is not readable due to rust?
In no case do not clean the number with a metal brush or sandpaper yourself - this can be regarded as the destruction of the marking. Contact the traffic police to receive a referral for examination. Experts will perform chemical etching or other procedures to restore the readability of the numbers.
Where is the body number on Toyota cars?
Most of the modern Toyota There is no separate body number, VIN is used. On older models (until the 2000s), the body number could be embossed on the partition of the engine compartment or on the glass of the rack. The exact location depends on the specific model and year of release.
Does the body number affect the cost of insurance?
The body number itself does not affect the coefficient, but it is a mandatory identifier in the policy. An error in the body number (or VIN if used in its place) may result in the policy being considered invalid and the insurance company refusing to pay or claiming reimbursement of costs.
Can I change the body number when replacing the frame?
Replacing a frame (which is often a load-bearing element and has a number) is equated with replacing a body. This requires mandatory registration of changes in the design in the traffic police. After replacement, it is necessary to undergo examination, obtain a certificate and make changes to the PTS. Driving with a frame number that does not match the PTS is prohibited.
