In a method for sorting mail items which are unaddressed and held in a number of batches each batch is obtained and registered by recording at least one graphical feature of a mail item which uniquely describes the batch (i.e. clearly identifies the batch from other batches). The graphical reference feature is linked to a batch of unaddressed mail and an associated sorting plan. In a subsequent sorting of all batches, each batch is recorded once again and its reference feature is detected and it is distributed according to the sorting plan, if necessary to an end delivery point.
