VIN etching
From Wikipedia, the free encyclopedia
VIN etching is a countermeasure to motor vehicle theft. In its most common implementation. it involves the use of a stencil and glass etching paste to etch a vehicle's vehicle identification number (VIN) onto its windshield and windows. Any thief would have to replace the glass before selling the stolen vehicle, thus reducing or eliminating their profit.
Most of the parts on a vehicle have at least a partial VIN stamped on them, and reputable auto parts buyers will not buy parts that have identification numbers. Should a thief try to sell the parts from a vehicle for profit, those stamped parts carry a higher risk for both thief and disreputable auto parts seller. Since the glass has no identification number, and is often readily interchangeable with many different years and models of vehicle, there is often a much greater profit for the thief compared to other components on the vehicle.
Many etching companies will pay compensation in the event that an etched vehicle is stolen. Some vehicle insurance companies offer discounts off their premium for VIN etching. VIN etching is offered by many car dealerships.
