Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have
established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of the joint technical committee is to prepare International Standards. Draft International Standards
adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 15438 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee
SC 31, Automatic identification and data capture techniques.
Annexes A to N form a normative part of this International Standard. Annexes P to U are for information only.

Introduction
The technology of bar coding is based on the recognition of patterns of bars and spaces of defined dimensions.
There are various methods of encoding information in bar code form, known as symbologies, and the rules defining
the translation of characters into bar and space patterns and other essential features are known as the symbology
specification.
Manufacturers of bar code equipment and users of bar code technology require publicly available standard
symbology specifications to which they can refer when developing equipment and application standards. It is the
intent and understanding of ISO/IEC that the symbology presented in this standard is entirely in the public domain
and free of all user restrictions, licences and fees.

This International Standard specifies the requirements for the bar code symbology known as PDF417. It specifies
PDF417 symbology characteristics, data character encodation, symbol formats, dimensions, error correction rules,
decoding algorithm, and a number of application parameters.

The following definitions also apply to this International Standard.
3.1.1 Basic Channel Model:
A standard system for encoding and transmitting bar code data where data message bytes are output from the
decoder but no control information about the message is transmitted. A decoder, complying to this model,
operates in Basic Channel Mode.
3.1.2 Bar-space sequence:
The sequence which represents the module widths of the elements of a symbol character.
3.1.3 Cluster:
One of three subsets of PDF417 symbol characters, all of which are mutually exclusive. The symbol characters in
a given cluster conform with particular structural rules which are used in decoding the symbology.
