DIN CEN/TS 15844-4:2011 Postal services - ID-tagging of letter mail items - Part 4: State encoding specification for flats; English version CEN/TS 15844-4:2010
This part of the Technical Specification defines the representation of ID-tags as a Postal-4i symbology 4-state bar code printed on the front side of flats. Many of the provisions are applicable also to small letters and are therefore referenced by Part 5 of the specification (CEN/TS 15844-5), which covers these.
Postal-4i symbology 4-state encoding is the only encoding specification supported by this Technical Specification for the printing of ID-tags on the front of items.
