A method and system related to container identification through an electrical receptacle and plug associated with the container of an intermodal freight transport system is disclosed. According to one embodiment, a method includes coupling an electrical power plug of a container and an electrical power receptacle of a transport vehicle. Also, the method includes activating a tracking device of the container through a switch and actuator coupling. Further, the method includes verifying an identity of the container upon coupling the electrical power plug to the electrical power receptacle through an identification tag of the container and an electronic reader. Furthermore, the method may include conserving battery power through deactivating the tracking device of the container when the electrical power plug is de-coupled to the electrical power receptacle. The method may also include delivering an alert message to a driver when an incorrect container is identified.
