From Wikipedia, the free encyclopedia

RM4SCC is the name of the barcode symbology used by the Royal Mail for its Cleanmail service. It enables UK postcodes as well as Delivery Point Suffixes (DPSs) to be easily 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]

There are strict guidelines governing usage of these barcodes, which allow for maximum readability by machines.

They can be used with Royal Mail's Cleanmail system, as an alternative to OCR readable fonts, to allow businesses to easily and cheaply send large quantities of letters.

As the example below shows, the barcode consists of a start character, the postcode, the Delivery Point Suffix (DPS), a checksum character, and a stop character.

Royal Mail will also be exploiting this symbology to drive RED TAG, the UK implementation of intelligent mail tracking technology
