We give a combinatorial classification of postsingularly finite
exponential maps in terms of external addresses starting with the
entry $0$. This extends the classification results for critically
preperiodic polynomials [2] to exponential maps. Our proof relies on
the topological characterization of postsingularly finite
exponential maps given recently in [14]. These results illustrate
once again the fruitful interplay between combinatorics, topology
and complex structure which has often been successful in complex
dynamics.
