Did you report this to the police? If you did, surely you turned over the vin number. It's not appropriate for you to be tracking down the vehicle owner.
It depends on why you want the information. If you have a license plate number that is an alternative. If you don't have the license plate OR VIN number it is going to be pretty difficult. You would have to have a legitimate reason such as a hit and run or some other crime that the police were interested in pursuing during an investigation. Even if you had a VIN number you need a legitimate reason for finding out specific information like that. This is assuming that you are asking about a car that you do not know the VIN number to rather than a car not actually having a VIN number which is located in the drivers side dashboard by the windshield as well as other locations depending on year and vehicle. .
Leave a note with your name and number if you can't find the owner.
Give the owner your name, address, and tag number in person or in a note attached to the object that was hit. Report the crash immediately to the proper law enforcement agency.
