Prominently displaying a Vehicle Identification Number (VIN0, for example by etching it into the windows of a vehicle, may help deter theft by making the vehicle appear less appealing to thieves. Reported thefts are included as part of the vehicle history report that is searchable by VIN.
Often, car thieves attempt to alter the VIN of a stolen vehicle in some way, generally by replacing it with the VIN of a vehicle that was purchased legally. However, VIN etching or otherwise making sure that the VIN is easy to see from the outside of the vehicle allows police and others who are looking for the car to immediately identify it as the stolen vehicle. This step may help deter thieves who are looking to draw less attention to themselves.
