The status of a vertex x in a graph is the sum of the distances between x and all other vertices. The status sequence of a graph is the list of the statuses of all vertices arranged in nondecreasing order. It is well known that non-isomorphic trees may have the same status sequence. We show that a tree is uniquely determined by its status sequence if the only pairs of vertices that have the same status are endvertices.
