Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22742 was prepared by Technical Committee ISO/TC 122, Packaging.
It is based on ANSI MH10.8.6, General EAN.UCC Specifications, and standards on product packaging (e.g.
IEC 62090).

Introduction
Bar code marked product package labels are in widespread use in global industries. A number of different
standards exist, each designed to meet the requirements of the specific industry sector. For effective and
economic use within and between industry sectors, one common multi-industry standard is a necessity.
A bar code marked product package label is designed to facilitate the automation of inventory, distribution,
repair and point of purchase operations. The bar code information on the product package label may be used
as a key to access the appropriate database, which contains detailed information about the product including
information transmitted via EDI. In addition, a product package label may contain other information as agreed
between the trading partners.
Two-dimensional symbols may be included to assist moving greater amounts of product data from sender to
recipient.
Whereas ISO 15394 is intended to support the transportation function within the supply chain (e.g. from the
shipping dock, through the transportation processes, and to the receiving dock), this International Standard is
intended to support the logistic functions preceding and following transportation. At the origin point, this
International Standard is designed for use from manufacture to storage, to picking and packing, to delivery to
the shipping dock, and all associated inventory processes. At the destination point, it is designed for use from
the receiving dock to order checking, to storage, to consumption, and to all associated inventory processes
and reverse logistic processes.

INTERNATIONAL STANDARD ISO 22742:2005(E)

Packaging — Linear bar code and two-dimensional symbols for
product packaging
1 Scope
This International Standard
a) specifies the minimum requirements for the design of labels containing a linear bar code and
two-dimensional symbols on product packages to convey data between trading partners,
b) provides guidance for the formatting on the label of data presented in a linear bar code, two-dimensional
symbols or human-readable form,
c) provides specific recommendations regarding the choice of linear bar code and 2D symbologies, specifies
quality requirements and classes of bar code density,
d) provides specific recommendations regarding 2D symbologies, which allow a broad choice for general
use of scanning hardware (e.g. area imagers, linear imagers, single-line laser scanners, and rastering
laser scanners), and
e) makes recommendations as to label placement, size and the inclusion of free text and any appropriate
graphics.
This International Standard supports item identification and supply chain processes, at the product package
level, such as inventory control, picking, and point of use.
NOTE ISO 15394 supports the distribution and transportation business processes, so aiding the tracing and tracking
of unique shipments.
The purpose of this International Standard is to establish the machine-readable (e.g. bar code) and
human-readable data content of labels applied to product packages.
Intended applications include, but are not limited to, inventory, warehouse management, maintenance and
point of purchase.
While guidance is provided, specific label dimensions or marking areas, and the location of the information are
not defined in this International Standard. Before implementing this specification, suppliers and manufacturers
are advised to review and mutually agree on these details with their trading partners.
This International Standard does not supersede or replace any applicable safety or regulatory marking or
labelling requirements. It is intended to satisfy the minimum product package requirements of numerous
applications and industry groups. As such, its applicability is to a wide range of industries, each of which may
have specific implementation guidelines. This International Standard is applicable in addition to any other
mandated labelling requirements.

ISO 22742:2005(E)
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 19762 and the following apply.
3.1
Code 39
3 of 9 Code (deprecated)
discrete, variable length, bar code symbology encoding the characters 0 to 9, A to Z, and the additional
characters “-” (dash), “.” (period), space, “$” (dollar sign), “/” (slash), “+” (plus sign), and “%” (percent sign), as
well as a special symbology character to denote the start and stop character, conventionally represented as
an “*” (asterisk)
NOTE Each Code 39 symbol consists of a leading quiet zone, a start symbol pattern, symbol characters representing
data, a stop pattern, and a trailing quiet zone. Each Code 39 character has three wide elements out of a total of nine
elements. Each symbol consists of a series of symbol characters, each represented by five bars and four intervening
spaces. Characters are separated by an intercharacter gap. Each element (bar or space) is one of two widths. The values
of the X dimension (3.13) and wide-to-narrow ratio remain constant throughout the symbol. The particular pattern of wide
and narrow elements determines the character being encoded. The intercharacter gaps are spaces with a minimum
nominal width of 1X. See ISO/IEC 16388 for the Code 39 symbology specification.
3.2
Code 128
continuous, variable length, bar code symbology capable of encoding the full ASCII-128 character set, the
128 extended ASCII character set, and four non-data function characters
NOTE Code 128 allows numeric data to be represented in a compact double-density mode, with two data digits for
every symbol character. Each Code 128 symbol uses two independent self-checking features, character self-checking via
parity and a modulo 103 check character. Each Code 128 symbol consists of a leading quiet zone, a start pattern,
characters representing data, a check character, a stop pattern, and a trailing quiet zone. Each Code 128 character
consists of eleven 1X wide modules. Each symbol character is comprised of three bars alternating with three spaces,
starting with a bar. Each element (bar or space) can consist of one to four modules. Code 128 has three unique character
sets designated as Code Set A, B and C. Code set A includes all of the standard upper-case alphanumeric keyboard
characters, the ASCII control characters having an ASCII value of 0 to 95, and seven special characters. Code set B
includes all of the standard upper-case alphanumeric keyboard characters, lower-case alphabetic characters (specifically
ASCII character values 32 to 127), and seven special characters. Code set C includes the set of 100 digit pairs from 00
through 99, inclusive, as well as three special characters. The FNC1 character in the first character position after the start
code of Code 128 designates that the data that follows complies with the UCC/EAN-128 standards. See ISO/IEC 15417
for the Code 128 symbology specification.
3.3
component
part, assembly or raw material that is a constituent of a higher level assembly
3.4
component packaging
commercial unit of components (3.3) defined by the supplier, including, if applicable, their means for
protection, structured alignment or for automated assembly
NOTE Component packaging may include: a) leaded components taped on reels or in ammo boxes according to
IEC 60286-1 and IEC 60286-2; b) surface mount devices (surface mount components), taped on reels according to
IEC 60286-3 and in bulk case IEC 60286-6; c) integrated circuits (ICs) in stick magazines according to IEC 60286-4, or in
matrix trays according to IEC 60286-5. Compare product package (3.32).
3.5
country of origin
manufacturing country wherein the product obtained its present identity as a part, subassembly or finished
product

ISO 22742:2005(E)
3.6
data element separator
specified character used to delimit discrete fields of data
3.7
data element title
part of the data area title for linear code that gives a brief description of the data element
EXAMPLES Part number and customer number.
NOTE The data element may contain abbreviations.
3.8
data matrix
error correcting two-dimensional matrix symbology, capable of encoding various character sets including
strictly numeric data, alphanumeric data and all ISO/IEC 646 (ASCII) characters, as well as special character
sets
NOTE 1 It was developed by International Data Matrix in 1989 with finalized design in 1995.
NOTE 2 The symbology has error detection (3.16) and error correction (3.15) features. Each data matrix symbol
consists of data regions that contain nominally square modules set out in a regular array. A dark module is a binary 1 and
a light module is a binary 0. There is no specified minimum or maximum for the X or Y dimension. The data region is
surrounded by a finder pattern that is surrounded by a quiet zone on all four sides of the symbol. The finder pattern is a
perimeter to the data region and is one module wide. Two adjacent sides are solid dark lines used primarily to define
physical size, orientation and symbol distortion. The two opposite sides are made up of alternating dark and light modules.
These are used primarily to define the cell structure but can also assist in determining physical size and distortion. The
intellectual property rights associated with data matrix have been committed to the public domain. See ISO/IEC 16022 for
the data matrix symbology specification.
3.9
dot
localized region with a reflectance that differs from that of the surrounding surface
3.10
dot misalignment within a cell
distance between the physical centre point of a dot (3.9) and the cell centre point
3.11

3.13
element width
“X” dimension
thickness of an element, measured from the leading edge of an element to the trailing edge of the same
element
3.14
erasure correction
use of the error correction (3.15) characters to correct data errors that have known locations
NOTE These locations can have insufficient contrast in the image, can fall outside of the image field, or can have
incorrect parity for symbologies with symbol character parity. Only one error correction character is required to correct
each erasure.

---------------------- Page: 9 ----------------------
ISO 22742:2005(E)
3.15
error correction
mathematical procedure that allows the detection and rectification of errors to take place
3.16
error detection
use of the error correction (3.15) characters to detect the fact that the number of errors in the symbol
exceeds the error correction capacity
NOTE Error detection will keep the symbol from being decoded as erroneous data. The error correction algorithm
can also provide error detection by detecting invalid error correction calculation results.

ITF
bar code symbology where two characters are paired, using bars to represent the first character and the
interleaved spaces to represent the second character, encoding the ten digits 0 through 9
NOTE Each character has two wide elements and three narrow elements for a total of five elements. This is most
commonly represented in the U.P.C. Shipping Container Symbol (SCC-14). See ISO/IEC 16390 for the Interleaved Two of
Five symbology specification.

PDF417
error correcting two-dimensional multi-row symbol
NOTE 1 This was developed in 1992 by Symbol Technologies; PDF417 symbols are constructed from 4 bars and
4 spaces over 17 modules.
NOTE 2 The symbol size is from 3 to 90 rows. There is no specified minimum or maximum for X or Y dimension. With
at least the recommended minimum level of error correction (3.15), the recommended Y dimension is 3X. With less than
the minimum recommended level of error correction, the recommended Y dimension is 4X. A quiet zone of 2X is specified
on each side of a symbol. Because of delta decode techniques, the symbology is immune from uniform bar width growth.
PDF417 supports cross-row scanning. The intellectual property rights associated with PDF417 have been committed to
the public domain. See ISO/IEC 15438 for the PDF417 symbology specification.
3.32
product package
first tie, wrap or container of a single item or quantity thereof that constitutes a complete identifiable pack
NOTE A product package may be an item packaged singularly, multiple quantities of the same item packaged

ISO 22742:2005(E)
4 Label data content and requirements
4.1 General
Before implementing this specification, suppliers and manufacturers should review and mutually agree on
specific labelling details with their trading partners. The labelling requirements of this International Standard
and other standards may be combined into one label or appear as separate labels.
The label format accommodates both mandatory and optional data elements.
The number included in the character count is exclusive of overhead characters such as start and stop
characters, data identifiers or application identifiers and any other characters required by a standard
symbology specification to properly encode data.
All data elements encoded in a machine-readable medium shall be preceded by the appropriate Data
Identifier (DI) defined in ISO/IEC 15418 and ANSI/MH10.8.2 Data Identifier, or the appropriate Application
Identifier (AI) defined in ISO/IEC 15418 and the General EAN.UCC Specifications.
The choice between EAN.UCC Applications Identifiers or Data Identifiers for any user will normally be defined
in the applicable industry convention being followed.
Other industries developing product or shipment identification conventions should consider business practices,
information requirements and systems capabilities of the trading partners in choosing between Data Identifiers
and EAN.UCC Applications Identifiers. The user may also consider the following guidelines.
a) EAN.UCC Applications Identifiers (AIs)
The definitions of the EAN.UCC Applications Identifiers (AIs) are supported by application guidelines. The
EAN.UCC AIs, and associated guidelines, have been designed for international and multi-sectorial trading
purposes.
The EAN/UCC item identification system and related encodation standard are complemented by the
EAN/UCC-maintained Application Identifiers, hereafter referred to as “EAN.UCC Applications Identifiers”
(EAN.UCC AIs). This standard comprises two principal elements that are the key to any encoding system:
the data content and the data carrier.
The use of EAN.UCC AIs is subject to the rules established by EAN and UCC.
EAN.UCC AIs identify generic and simple data fields for use in cross-sectorial and international supply
chain applications. The General EAN.UCC Specifications provide rules for the definition, format and
structure of the data fields.
Each EAN/UCC AI consists of two or more characters. The first two digits determine the length of the AI.
A list of two digit codes indicating the predefined length of existing and future AIs and their data fields are
contained within the General EAN.UCC Specifications.
b) Data Identifiers (DIs)
The descriptions in the Data Identifier list are general in nature and are used in industrial and international
applications. Specific application guidelines provide the detailed definition used amongst trading partners.
The full list of registered Data Identifiers (DIs) and the full specification for their use are found in
ANSI MH10.8.2.
DIs may be used with any alphanumeric data carrier and are designed to ensure cross-industry
commonality of data identifiers used in automatic identification technologies.
DIs have a format of one alphabetic character alone, or one alphabetic character prefixed by one, two or
three numeric characters.
8 © ISO 2005 – All rights reserved

---------------------- Page: 13 ----------------------
ISO 22742:2005(E)
It is recommended that data structures used to identify products or the traceability of products include
identification of the organization providing the coding as well as the specific coding structure.
