Station-identification apparatus for use in reception of telephone calls from stations at each of which there is repetitively superimposed on the call therefrom a respective series, peculiar to that station, of numeral-representing signals. The received signals are screened in various respects, and the numerals represented by a series thereof are sequentially stored. Output means are actuated to read out the stored signals under conditions which minimize the risk of erroneous read-out.
