Objects are sorted according to predetermined groups of sorting feature values. In particular, postal items are sorted according to groups of delivery addresses. A sorting system sorts the objects into a sequence so that all objects with sorting feature values belonging to the same predetermined value group are situated one directly behind another in this sequence. The sorting system has x1 storage subregions, x2 sorting subregions and a sorting plan. The objects are apportioned to the x1 storage subregions. For each storage subregion, an apportionment step is then carried out, in which the objects from this storage subregion are apportioned to the x2 sorting subregions. The apportionment steps are performed one after the other. Each apportionment step, is followed by a sorting and output step for each sorting subregion, in which the objects from this sorting subregion are brought into a sequence in accordance with the sorting feature values and this sequence is output.
