A method and an apparatus for sorting flat mail items into delivery point sequencing include sorting the mail items into sequence and deposited them in a sorting facility with a number of F compartments. In order to achieve sorting into delivery point sequencing to a plurality of mail addresses with a comparatively small number of compartments, the mail items are presorted into a number of M storage modules, which differ from the compartments in that they have an internal withdrawal apparatus, in a presorting facility.
