The question of searching for the state registration plate of a vehicle according to the Certificate of Registration (CTC) arises among drivers quite often. Typically, this need arises when trying to contact the owner of a car that has blocked the exit, or when you want to check the car’s history before purchasing, knowing only the VIN or document number. However, from the point of view of the legislation of the Russian Federation, the situation here is ambiguous and strictly regulated.
Unfortunately, official online services, which would allow anyone to enter an STS number and instantly receive a state number, do not exist. This is due to the Federal Law “On Personal Data”, which protects information about vehicle owners. Traffic police databases are closed to public access, and direct receipt of such information without legal grounds is a violation of confidentiality. However, there are indirect methods and specialized services that help solve related problems.
In this article, we will analyze in detail why direct access is closed, what legal verification methods are still available to citizens, and how to protect yourself from scammers who offer to “break through” a car using any database for money. You will learn about the real possibilities of State Services portals, commercial aggregators and actions in emergency situations.
Why can't you just dial the number online?
The main reason for the lack of public databases linking STS and state number plates is the protection personal data. The registration certificate contains not only technical information about the car, but also information about its owner. According to the law, only authorized bodies have access to this information: police, bailiffs, tax authorities and, in some cases, insurance companies within the framework of compulsory motor liability insurance.
If anyone could find out the license plate number and then the owner by the document number, this would open up a wide avenue for fraud, stalking and illegal collection of information. This is why government agencies such as traffic police or Ministry of Internal Affairs, do not provide an API or open forms for such requests. Any sites that promise to do this for free are most likely either broken or collecting your data for phishing purposes.
⚠️ Attention: Beware of sites that require payment for “access to the traffic police database.” In 99% of cases, you will lose money, and the information will be taken from open sources or generated by chance.
There is also a technical aspect to protection. The Ministry of Internal Affairs databases are segmented and have a multi-level system of protection against external connections. Even if there is a legitimate reason (for example, you are an attorney in a car accident case), requests are often made through formal paper or electronic requests to the departments, rather than simply entering numbers on a website.
Legal ways to check a car by document number
Although there is no direct conversion of “STS to State Number,” there are legal ways to obtain information about a car using the STS number or VIN code. These methods will not give you the owner's name or phone number, but they will allow you to find out the history of the car, which is often the ultimate goal of the check.
One of the most reliable ways is to use the service Autocode or similar aggregators working with official databases. If you have the STS number on hand (it is indicated in the “Series and number” line), you can check whether the car is pawned, stolen or wanted. To do this, you will also need the VIN code, which can often be found in open sources or in photos of the car if you are considering buying it.
Another important tool is checking the policy OSAGO. A form is available on the RSA (Russian Union of Auto Insurers) website that allows you to find out whether a car is insured using the policy number or STS data. This indirectly confirms the legality of the document. If the system produces an error or the data does not match, this is a serious reason to be wary.
- 🚗 Theft check: The Ministry of Internal Affairs databases allow you to check whether a vehicle is on the federal wanted list by body or chassis number.
- 📄 Registration history: You can find out the number of previous owners and periods of ownership, which helps to identify resellers.
- 🔧 Technical data: Compare the color, year of manufacture and engine size with the data in the sales advertisement.
Using the State Services portal for drivers
Portal Public services is the only government channel through which a citizen can access some information about his car or cars where he is registered. However, the functionality is limited. You will not be able to identify someone else's car simply by the STS number if you are not its owner or do not have a power of attorney duly executed in the system.
For car owners, the service provides the opportunity to check fines, registration history and check for restrictions on registration actions. If you bought a used car and want to make sure that the seller told the truth, ask him to show the smartphone screen with the Public Services application open or the “Transport” section. All linked vehicles will be visible there.
In the “Traffic Police Fines” section, you can enter your STS number and driver’s license number. This will allow you to see the fines issued specifically for this vehicle. Although this will not give you the license plate number directly (it is often known to you at the time of checking fines), it confirms the “document-car” link.
⚠️ Attention: Never give scans or photos of your STS to strangers for “checking”. The document contains data sufficient to attempt fraud or duplicate the document.
It is important to note that the functionality of the portal is constantly updated. New services appear periodically, for example, checking ownership history. However, the principle remains the same: only the owner or a person acting under a notarized power of attorney has access to data.
Use the QR code on the back of the new STS. By pointing your smartphone camera at it, you will receive an encrypted string with data that can be checked against the database without entering numbers manually and without the risk of making a mistake.
Commercial services and databases: is it worth paying?
There are many commercial services on the market, such as Carfax (for USA), AutoDNA or Russian analogues. They aggregate data from various sources: insurance companies, service centers, customs declarations and public advertisements for sale. They work on the principle of a paid report.
Should you trust them? In most cases, yes, when it comes to checking the car's history before purchasing. These services can show whether the mileage is incorrect, whether there have been serious accidents, or whether the car was used in a taxi. However they they don't give the ability to find the owner by STS number, circumventing the law. Their task is to tell the story of the hardware, and not to reveal the identity of the person.
Below is a table comparing the capabilities of various information sources:
| Data source | Cost | Shows owner | Shows accident history | Official status |
|---|---|---|---|---|
| Traffic police website | Free | No | Yes (partially) | Officially |
| Public services | Free | Only yours | No | Officially |
| Commercial services | Paid | No | Yes (details) | Aggregator |
| Private bases ("breaking through") | Various | Fraud risk | Unknown | Illegal |
The use of such services is justified when buying an expensive car. A report worth several hundred rubles can save you from buying a “constructor” or a car with wrong license plates. But remember: if the service promises to “break through the Ministry of Internal Affairs database” and give out the owner’s phone number, this is a marker of illegal activity.
What to do if a car is blocking the exit
The most common situation when a driver urgently needs to find out the license plate number of a car or contact the owner is parking conflicts. The car got into your “pocket”, blocked the exit or took your place. In this case, knowing the STS number (if you somehow know it) will not help, you need a state number.
If a car is parked in violation of traffic rules (on the sidewalk, on the lawn, or blocks the passage), the most effective way is to call a tow truck or contact the police. Employee traffic police using the STS number (which they will run through the database) or the license plate number, they will quickly find the owner’s phone number and oblige him to remove the car.
There are also mobile applications for parking (for example, “Moscow Parking” or analogues in other cities). Some of them have a "Report illegal parking" function. You take a photo of the offender, and the operator contacts the owner. This is a legal and fast method that does not require personal data.
☑️ Algorithm of actions when blocking an exit
There is no point in trying to find the owner on your own through friends in structures or paid databases. Firstly, this is time, which does not exist. Secondly, this may be regarded as a violation of the law on personal data if the fact of the appeal comes to light.
Legal risks and information protection
It is important to understand that the JTS is a document containing critical information. In the capable hands of attackers, data from the STS can be used to clone documents, sell a duplicate car, or issue microloans (in rare cases, if other data is available).
Legislation of the Russian Federation strictly punishes the illegal collection and dissemination of information about citizens. Article 137 of the Criminal Code of the Russian Federation provides for liability up to imprisonment for violation of privacy. Therefore, any “gray” methods of searching for car owners are at high risk.
If you are selling a car and posting a photo of the STS in an ad, be sure to hide the series and document number, as well as the VIN code. Leave only the make, model, and possibly year of manufacture visible. This will protect you from attempts to alter documents or create false advertisements for the sale of your car.
Is it possible to find out the owner through STS through a lawyer?
Yes, a lawyer's request is a legal tool. If there is a lawsuit underway (for example, after an accident where the culprit fled), the lawyer can send a request to the traffic police to establish the identity of the owner of the vehicle.
Frequently asked questions and misconceptions
There are many myths surrounding the topic of car inspections. Let's look at the most popular of them so that you don't fall for scammers.
You can often come across the statement that there are “holes” in the security of traffic police databases. In fact, data leaks more often occur not due to hacking of the Ministry of Internal Affairs servers, but due to unscrupulous employees of car dealerships, insurance companies or inspection centers with legal access to databases. That is why buying a “breakthrough” from private traders is supporting a criminal conspiracy.
Also, many people confuse the STS number and the chassis number. The chassis number (VIN) is a unique identifier of the vehicle itself, its “DNA”. The STS number is the identifier of the document issued by the state. When you sell a car, the STS changes, but the VIN remains the same. It is more reliable to check the history using the VIN.
There is no legal way for an ordinary citizen to find out the full name and telephone number of the owner of a car only by the STS number. All offers of this kind are either fraud or illegal access to databases.
Is it possible to find out the license plate number of a car using the STS through the traffic police application?
No, the official traffic police application does not provide such a function for citizens. It allows you to check fines (knowing the license number and STS) and registration history, but does not convert the document number into the license plate of someone else’s car.
What should I do if I bought a car, but the previous owner did not deregister it?
You need to contact any traffic police department with an application to terminate registration in connection with the sale. You will need a purchase and sale agreement (SPA). After this, the license plates and STS will be put on the wanted list, and the new owner (if he tries to drive) will face a fine and the license plates will be removed.
Is it dangerous to show a photo of an STS on the Internet when selling?
Yes, it's dangerous. Fraudsters can use the data to create duplicate documents or try to defraud other buyers. Always hide the document number and VIN in photographs.
Are there paid databases that actually work?
There are databases collected from data leaks (the so-called “drain”). They may contain current information, but their use is legally questionable and the data may be incomplete or out of date. You cannot rely on them as the only source of truth.
How to check a car if the seller only shows a photo of the STS?
If the seller hides the license plate number but shows the STS, this is a red flag. Take a photo of the STS (hiding personal data) and try to get the VIN through paid history services. If the VIN is hidden or filled with a marker, refuse the deal, there is a high probability of problems with the law.
In conclusion, remember: transparency in the automobile market is increasing, but the privacy of citizen data remains a government priority. Use only official channels for checks, take care of your documents and do not believe the promises of “magic” online services that violate the law.
