An elevator system having an elevator car in an elevator shaft and having a measuring tape in the elevator shaft for determining the position of the elevator car in the elevator shaft. The measuring tape is arranged vertically in the elevator shaft and has optical coding for length measurement. At least one marking element which has optical marking is arranged on the measuring tape. The marking element is fixedly arranged on the measuring tape. A sensor device which comprises a lighting source and a sensor which form a detection field for detecting the measuring tape is attached to the elevator car. The elevator system comprises an evaluation device for decoding the codings in the detection field and a control device for controlling the elevator system as a function of the coding and/or of the position of the at least one marking element on the measuring tape.
