In everyday speech, drivers often use simplified language, calling any set of numbers associated with the car a “number”. However, in legal and technical documentation, as well as in normative acts of the Russian Federation, each designation has a strictly defined name and purpose. Confusion in terms can lead to misunderstandings when communicating with traffic police officers, errors when filling out insurance policies or problems when registering a vehicle. It is therefore important to distinguish clearly which identity is being referred to in a particular context.
The main identifier visible from the outside of the car is the state registration plate, which is commonly referred to simply as the "number". It is the camera that checks the violations, and it is he who is indicated in the vehicle registration certificate (STS). However, there is another, hidden “passport” of the car – identification number (VIN), stamped on the body and in the documents. Understanding the difference between these concepts is basic for any car owner who wants to understand correctly in the issues of operation and ownership of property.
In this article, we will discuss in detail how the various marking elements of the car are correctly called in accordance with the current legislation. We will analyze the differences between the state registration mark, VIN code and aggregate numbers, as well as consider the requirements for their installation and readability. This knowledge will help you avoid fines and feel confident in any bureaucratic procedures involving the car.
Official name of external identifier
What is called a “number” is legally and technically called a “number” state-mark (GRO). This term is fixed in GOST R 50577-2018, which regulates the requirements for the appearance, fonts and sizes of the plate. It is the GRZ that is the main visual identifier of the vehicle in the flow and is assigned when registering with the Ministry of Internal Affairs. It is important to understand that the character set itself (e.g. A 123 AA 777) is a state registration number, and a metal plate with the symbols applied is a sign.
GRZ performs the function of linking the vehicle to a specific owner in the traffic police database. When selling a car, license plates usually remain on the car, although the law allows you to keep them for the previous owner, subject to certain conditions. Retroreflective properties The clarity of the characters on the sign is strictly controlled: if the symbols are erased, deformed or closed with foreign objects (frames with advertising), this may entail administrative responsibility.
⚠️ Attention: The use of a frame that covers at least one character or region on the state registration plate is a violation and may lead to a fine or deprivation of rights for modifying the number.
Standard Russian license plate consists of several elements that carry different semantic load. The alphanumeric combination is unique within the series, and the region code indicates the federal entity where the car was registered. Recently, the format of signs is undergoing changes, new types of GRZ for retro cars, motorcycles and ATVs are appearing, which is also reflected in the updated standards.
It is worth noting that state-mark It is the property of the state, not the owner of the car. This means that when a vehicle is disposed of or in certain legal procedures, the marks may be withdrawn or deposited. The owner receives only the right to use them during the period of ownership of the vehicle. Replacement of signs may be required for their loss, theft or physical wear, making reading the symbols impossible.
VIN code: hidden passport of the car
If the state number can be changed, vehicle identification number (VIN) stays with the machine from the moment of de-lineation to disposal. The abbreviation VIN is derived from the English Vehicle Identification Number. This code is knocked out on the body (most often on a glass of the rack, bulkhead of the engine compartment or on the spangeron) and is the main means of protection against theft and doubles. Unlike the GRP, the VIN code does not change when reselling the car and contains encoded information about the manufacturer, model, year of release and configuration.
Verification of the VIN code is a mandatory procedure when buying a used car. By this number you can find out the history of ownership, participation in an accident, being in pledge or wanted. Structure of VIN code It is standardized by international standards and consists of 17 characters, where each sign carries certain information. The first three characters (WMI) indicate the manufacturer, the next six (VDS) describe the model and characteristics, and the last eight (VIS) contain the production number and year of release.
What if the VIN code on the body is not readable?
If the identification number on the body corroded (rusted) or damaged by corrosion so much that it is not readable, it is necessary to conduct a forensic examination. Only after confirmation of the coincidence of hidden markings and the absence of signs of interference, the traffic police can allow registration or issue a certificate for knocking out a new number (in rare cases). Self-cleaning or welding of the place with VIN is prohibited.
In documents for the car, such as the Vehicle Passport (PTS) and the Certificate of Registration (CTC), the VIN code is indicated necessarily. An error in even one character when filling out an insurance policy or a diagnostic card can make these documents invalid. Therefore, when making papers, it is necessary to check each letter and number with metal plates on the body.
Modern cars can have multiple duplicate VINs in hidden locations, which provides additional protection. Identification number It is applied by the method of shock branding or laser engraving. Any traces of alteration, welding or chemical etching at the site of application of the VIN are a red flag for law enforcement and may be grounds for the detention of the vehicle and the appointment of a comprehensive examination.
Other marking numbers and plates
In addition to the main identifiers, the car has a number of other numbers that are important for technical operation and maintenance. One of these is the body number (or frame), which in older cars may differ from the VIN, but in modern cars usually duplicates it or is part of it. There's also enginewhich is knocked out on the cylinder block. Although the engine number is often indicated in the “Note” column or in a separate line, its verification is important when replacing the power unit.
On each car there is a factory plate (name plate), located on the body rack or in the hood space. It contains information about the manufacturer, date of manufacture, allowed maximum weight and weight of the equipped car. This data is critical to the proper selection of parts and understanding of the technical limitations of the vehicle. Factory marking It also includes body color and interior type codes, making it easier to find original materials for repairs.
The table below compares the main types of numbers found on the car:
| Type of marking | Location. | Substantive function | Can we change? |
|---|---|---|---|
| State registration mark | Front and rear of the body | Identification in the flow, binding to the owner | Yes (on re-registration) |
| VIN code | Body (glass, sparser) | Unique identification, protection against theft | No (strongly prohibited) |
| Engine number | Cylinder block | Identification of the power unit | Yes (on engine change) |
| Factory plaque | Body rack/under the hood | Technical parameters and release date | No (only replacement on loss) |
When carrying out repairs, especially bodywork, it is important to keep all factory markings readable. If during welding or painting it is intended to affect the zones with the numbers, it is necessary to take measures for their preservation or documentary fixation. In some cases, an expert is required to record the status of markings before the work begins.
Requirements for installation and readability of numbers
The legislation imposes strict requirements for the installation of state registration marks. According to traffic rules and GOST, signs must be installed on the places intended for their fastening, and fixed so that the possibility of their loss or change is excluded. Inclination angle the sign must not exceed 10 degrees vertically and 5 degrees
