The Vehicle Identification Number (VIN) is typically found on the driver's door frame of a vehicle. This location is standardized across most vehicles and allows for easy access to the VIN for identification purposes. The driver's door frame is a logical place for the VIN because this area is often visible when the door is opened, making it convenient for authorities, service technicians, and vehicle owners to check details like registration, insurance, and recall information.

The engine block is not a common location for the VIN, as it is primarily associated with engine specifications rather than vehicle identification. While a vehicle's operator's manual and service manual may contain the VIN, they do not serve as physical locations where the VIN can be found on the vehicle itself. Instead, these manuals typically reference the VIN in text format, but it is physically stamped or engraved on the vehicle's body or frame to indicate its unique identity.
