Foreword
This document (CEN/TS 15844-5:2010) has been prepared by Technical Committee CEN/TC 331 “Postal
services”, the secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
NOTE This document has been prepared by experts coming from CEN/TC 331 and UPU, under the framework of the
Memorandum of Understanding between the UPU and CEN.
1)
This document, CEN/TS 15844-5, is the CEN equivalent of UPU standard S18e-5. It may be amended only
after prior consultation, between CEN/TC 331 and the UPU Standards Board, in accordance with the
Memorandum of Understanding between CEN and the UPU.

The UPU’s contribution to the document was made, by the UPU Standards Board and its sub-groups, in
accordance with the rules given in Part V of the "General information on UPU standards".
This document forms Part 5 of a multi-part CEN/TS 15844, Postal services — ID-tagging of letter-mail items. It
should be read in conjunction with the main body of the specification, CEN/TS 15844-1. It also relies heavily
on Part 4 of the specification, CEN/TS 15844-4.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,
Spain, Sweden, Switzerland and the United Kingdom.

The Universal Postal Union (UPU) is the specialized institution of the United Nations that regulates the universal postal service. The
postal services of its 189 member countries form the largest physical distribution network in the world. Some 5 million postal employees
working in over 660 000 post offices all over the world handle an annual total of 425 billion letters-post items in the domestic service and
almost 6,7 billion in the international service. Some 4,5 billion parcels are sent by post annually. Keeping pace with the changing
communications market, posts are increasingly using new communication and information technologies to move beyond what is
traditionally regarded as their core postal business. They are meeting higher customer expectations with an expanded range of products

and value-added services.
2)
The UPU's Standards Board develops and maintains a growing number of standards to improve the exchange of postal-related
information between posts, and promotes the compatibility of UPU and international postal initiatives. It works closely with posts,
customers, suppliers and other partners, including various international organizations. The Standards Board ensures that coherent
standards are developed in areas such as electronic data interchange (EDI), mail encoding, postal forms and meters. UPU standards are
published in accordance with the rules given in Part VII of the General information on UPU standards, which may be freely downloaded

from the UPU world-wide web site (www.upu.int).
Introduction
A general introduction to all parts of the specification is provided in CEN/TS 15844-1. This part deals only with
the encoding of ID-tags in the form of a 4-state bar code printed on the front side of small letters. For
consistency with Part -4 of the specification, on which it depends, it is arranged under six main headings:
Clause No. Description of content
5 Usage limitations: defines limitations on the use of the Postal-4i 4-state encoding of ID-tags
specified in this document;
6 Value range limitations: defines limitations on the values of data elements used in ID-tags which
are to be represented on small letters in the form of a Postal-4i bar code;
7 Encoding specification: specifies the construction of a 4-state bar code from ID-tag data
elements;
8 Printing of the bar code: to allow the association of computer data with a physical item, the ID-tag
is printed on the item itself. This clause defines required ink and printing parameters;
9 Reading and interpretation of Postal-4i ID-tags: specifies the validation and error correction
requirements associated with the reading of ID-tags represented using Postal-4i symbology;
10 Conversion to the message and binary representations: describes the correspondence between
4-state bar coded representation and the binary and message interchange representations
defined in CEN/TS 15844-1.
These are complemented by two informative annexes, the first providing references to an example
implementation of the Postal-4i ID-tag generation algorithm and the second providing a number of example
ID-tags, generated using this implementation.
1 Scope
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 small letters.
Postal-4i symbology 4-state encoding is the only encoding specification supported by this Technical
3)
Specification for the printing of ID-tags on the front of items.
NOTE Representation in the form of fluorescent BNB bar codes printed on the reverse side of small letters (not flats)
is covered in CEN/TS 15844-2 and CEN/TS 15844-3.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

3 Terms and definitions
A number of common terms used in this document are defined in the UPU Standards glossary, in documents
referred to in normative references and in the bibliography. Definition of frequently used or particularly
important terms as well as other terms introduced in this document are given below.

5 Usage limitations
The 4-state bar coded representation of ID-tags defined in this part of the specification is intended for use on
the front side of small letters in area F1. Printing of ID-tags in this area is allowed only on domestic items and
on items addressed to countries in which the delivery post has confirmed willingness to accept items with a
4-state ID-tag in that area.
NOTE 1 Many posts use area F1 for the encoding of routing data, used to support automated sorting of both domestic
and incoming cross-border items. The printing of an ID-tag in area F1 on cross-border items to countries which require F1
to be kept clear for this purpose could cause serious disruption to such countries' automated processing systems and
could result in misprocessing or substantial delay to the items concerned. It would also be in breach of the UPU letter post
regulations. This Technical Specification therefore requires that postal administrations making use of area F1 for ID-tag
encoding should take care to avoid such use of area F1 on items addressed to other countries that have not declared their
willingness to accept items with an ID-tag in area F1 as standard items.

3) References to "this Technical Specification" should be interpreted as references to CEN/TS 15844 as a whole, not
only to Part 5.
The specification may be applied to the printing of ID-tags in other areas on the front of items. It shall not be
used in area R1 on the reverse side.
NOTE 2 Usage in other areas on the front is permitted, but could result in interference with, or by, codes placed by
other systems and is not recommended.
NOTE 3 Usage on the reverse side, and particularly usage in area R1, could seriously disturb the operation of older
systems which are designed to work only with BNB encodings of ID-tags and is not permitted.
