Abstract: An article tracking system includes a delivery zone transmitter associated with at least one physical article delivery location for transmitting data identifying that physical location, a zone detector carried by at least one manually operated article delivery vehicle for detecting the physical proximity of the vehicle to the delivery zone, and a signal device operatively associated with the zone detector for outputting a signal indicating the physical proximity of the vehicle to the delivery zone. Therefore, an operator of the vehicle is informed that the vehicle is in the proper delivery zone for delivery of an article.
