What is the difference between Direct and Residue selections?
• For Mailsort 1400 mailings are split into two levels: Direct selections which are sorted to the level of a local Delivery Office and generate a higher discount; the Mailsort Database contains around 1,400 Direct selections Residue selections which are sorted to a Postcode area level. As the name suggests, they take remainders (or residues) from Direct selections. There might not be enough items to meet the minimum volume criteria for a Direct selection (25 items for a letter-sized item or 5 items for a large letter, A3 packet and packet-sized items), or they may have no Postcode or only part of a Postcode and therefore need to be matched via the posttown. The Mailsort Database contains about 120 Residue selections • For Mailsort 700 a number of Direct selections are combined to reflect the fact that mail is sorted by a mechanised process. This level of sorting is abbreviated to the term ‘Mech Direct selections’.
