The invention relates to a hand-held audio distribution frame number identification apparatus. The apparatus comprises a plug connector, a number identifier host and a cable. The plug connector comprises a plugging part and a hand-held dismounting part. An interface is arranged on the hand-held dismounting part. A contact for cable conduction is arranged on the interface. A support assembly is arranged on the hand-held dismounting part. A locking assembly is arranged on the support assembly. The apparatus is advantageous in that the plugging part arranged on the plug connector is inserted in a distribution frame; the number identifier host is connected on the plug connector through the cable; identification is performed through a touch screen and a telephone MCU inside the number identifier host; and the telephone number of a corresponding interface of the audio distribution frame can be identified in an instant way. When operators change and maintain telephone numbers in a machine room, the influence of conventional label identification can be reduced. By means of the arranged hand-held dismounting part, plugging of the plug connector can be effectively prevented. The plug connector is further prevented from being damaged.
