Abstract: A high security mail box which comprises an elongated housing having a front wall, a rear opening and a chamber therein to receive and store incoming mail items. A facility in the elongated housing, is for depositing the incoming mail items within the chamber by a mail person. An access door is hinged to the rear opening of the elongated housing, wherein the access door will move between an open position and a closed position. A mechanism operatively associated with the access door, is for locking the access door in the closed position. An authorized person can disengage the locking mechanism to move the access door from the closed position to the open position, so that the authorized person can remove the incoming mail items from the chamber of the elongated housing.
