Where it is necessary to identify the vehicle owner information, a lot of: Ham got on the road, or you are in a traffic accident and the perpetrator fled.
More often than not we have at our disposal a car brand, its color and registration number.
But these data are sufficient.
Use the traffic database to learn about the host machine by number. It is best to go directly to someone from the traffic police with the request.
If a formal request, please provide your personal data, circumstances force you to apply, and the goal you are pursuing.
Please note that the information the authorities are reluctant to share, so make inquiries with the help of the same power structures: through the prosecutor's office, the Interior Ministry, the courts.
If this option does not suit you for any reason, try to use the base, laid out in the public domain on the Internet.
Note that some databases do not contain the latest information, and some of them - are paid.
