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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, 2 (see www.iso.org/directives ).

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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

This document was prepared by Technical Committee ISO/TC 68, Financial services, Subcommittee SC 8, Reference data for financial services.

This eighth edition cancels and replaces the seventh edition (ISO 6166:2013), which has been technically revised.

The main changes to the previous edition are as follows:

• clarification that the scope covers financial instruments as well as referential instruments;
• addition of new instrument types to which the ISIN code can be allocated (derivative products with EZ and ZZ prefix, baskets, emission allowances and carbon credits);
• addition of new minimum descriptive elements (Annex B).

Introduction

With the rapid expansion of international business in financial instruments, there was a need for a universally applicable international securities identification number (ISIN).

No worldwide numbering system existed at the time of the publication of the first edition of this document. Countries with a developed financial market identified issues of securities by means of code numbers, which are without any significance outside the country concerned. Instruments of the same issue were identified by means of different numbers in the country where they were physically held, booked or both, with the result that the national numbers may not be applicable in cross-border transactions.

Because of its strong rationalization effect, an internationally applicable numbering system substantially facilitates and supports international business in financial instruments. Such a system is provided by this document. Since the publication of the first edition of this document, its scope has expanded from a focus on securities to a much broader range of financial instruments. In addition, since the publication of the first edition, the Registration Authority (RA) has relied on the work of national numbering agencies (NNAs) which play an integral role in this rationalization effort and in the implementation of this document.

In preparing this document, care has been taken to conserve the national systems to the maximum possible extent, not only because of the good routine and valuable experience collected in this field but also to facilitate the adoption of the worldwide system. Moreover, it provides a system which is easy to apply internationally and establishes an information network which ensures that the required information can be obtained worldwide immediately.

1 Scope
