A system is provided for locating an intended package, product, or other item that may be located in an area where a number of such packages may be located, such as a warehouse, a receiving area, or the like. The system allows personnel to quickly identify a particular package or package location from among other packages in the area. The system includes a wireless transmitter operative to transmit coded signals, each associated with a respective package to be located. A receiver device such as an RFID tag is disposed on or near each particular package being sought. The receiver device upon receipt of an interrogating signal from the transmitter and recognition of a unique identifying address code indicates its presence by an audible and/or visible signal that can be directly sensed by a human.
