The 17-character VIN is required to process your NIO COC document. You can locate it in the following positions:

• On the windscreen: Stamped on a metal plate visible through the driver's side lower windscreen.
• In the engine bay / chassis: Stamped on the vehicle frame rail or on the manufacturer door-pillar certification label.
• Important note: Enter the VIN without spaces when ordering. Ensure you do not confuse the letter 'O' with the digit '0'.
