A telecommunication device (1) is provided for identification of a caller number of a calling party. The telecommunication device (1) includes a caller identification circuit (5), a memory (10) for storing numbers of callers and a comparator (15) for comparing numbers of calling parties with the caller numbers stored in the memory. The telecommunication device supplies data of the calling party to a display device when the caller number of a calling party agrees with a caller number stored in memory. A truncation of the caller number of the calling party at its end by a predetermined number of digits occurs when there is no agreement between the caller number of the calling party and any of the numbers stored in the memory and a comparison of the branch exchange main numbers stored in the memory with the shortened caller number occurs.
