ABSTRACT A telephone apparatus includes a decoder, a memory, a comparison circuit and an output device. The decoder serves to detect telephone number information of a calling side which is transmitted together with bell signals through a telephone line to decode the telephone number information. The memory is stored with telephone number data of call sides in correspondence with plural operation keys, respectively. The comparison circuit serves to compare the output data of the decoder with the telephone number data stored in the memory when a call is received. When any coincidence is detected between the output data of the decoder and the telephone number data of the memory on the basis of the comparison result of the comparison circuit, the output device notifies an user that the call corresponds to one of the telephone number data stored in the memory. The output device includes plural display (indication) units which are respectively provided in correspondence with the plural operation keys, and a driving control circuit for selectively driving the display unit of the operation key corresponding to the coincident telephone number data on the basis of the comparison result. Alternately, the output device may include audio data memory in which names of call sides corresponding to the telephone number data stored in the memory are stored as audio data in correspondence with the operation keys, an electro-acoustic transducer to which the audio data read out from the audio data memory are supplied, and a controller for reading out the audio data corresponding to the coincident telephone number data from the audio data memory and outputting (reproducing) the audio data from the electro-acoustic transducer on the basis of the comparison result.
