Destination calls entered by means of buttons (21-29) are each given a designation unique to the car and pick-up floor for that call and other calls to be serviced therewith, such as a letter (A-E), which is different from any other outstanding calls. Calls can be reassigned among elevators (UL, LL, UR, LR) whether they are in the same or different hoistways (LF, RT). Signs (31-39, 41-49) adjacent each hoistway are illuminated to display the designation of any call which is being answered by an elevator car approaching the floor. Thus, passengers are informed when their call is being answered by the signs identifying the call, rather than identifying any particular car. Another embodiement identifies (60, 31a, 41a) the hoistway landing doorway (1, 2) as well as a letter to allow passengers to wait adjacent to the hoistway landing doorway of the car which will serve them.
