RM4SCC

RM4SCC is the name of the barcode symbology used by the Royal Mail for its Cleanmail service. It enables UK postcodes to easily be read by a machine at high speed. This barcode is known as CBC (Customer Bar Code) within Royal Mail. Royal TNT Post uses a slightly modified version called KIX which stands for Klant index (Customer index); it differs from CBC in that it doesn't use the start and end symbols, and the checksum, separates the house number and suffices with an X and is placed below the address.^[1] The barcode encodes the postcode as well as the delivery point suffix and a checksum character. There are strict guidelines governing usage of these barcodes, which allow for maximum readability by machines. They are used with Royal Mail's Cleanmail system to allow businesses to easily and cheaply send large quantities of letters.
