In this postal sorting process, ordered lists (C11-C23) of the sort codes affixed to the mail items are compiled in the handling sorting offices (CTA1, CTA2), these lists being representative of the order of the rail items in the batches of mail items compiled during the handling sorting phase. These lists of codes are transferred from the handling sorting offices to the distribution sorting offices and during the processing of the batches of mail items in a distribution sorting office, the code read by machine on the mail items are compared with the codes extracted from said lists f codes with a view to recovering errors in reading said codes by machine.
