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, Part 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, Part 2. 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. www.iso.org/patents

Introduction
With the rapid expansion of the international securities business, there is 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
International Standard. Countries with a developed securities business identified issues of securities by
means of code numbers, which are without any significance outside the country concerned. Securities of
the same issue are identified by means of different numbers in the country where they are physically held
and/or booked. As a result, 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 securities business. Such a system is provided by this International
Standard. Since the publication of the first edition of this International Standard, the Registration
Authority (RA) relies on the work of national numbering agencies (NNAs) which play an integral role in
this rationalization effort and in the implementation of this International Standard.
In preparing this International Standard, 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 is aimed at creating a
system which is easy to apply internationally and at establishing an information network which ensures
that the required information can be obtained worldwide immediately.

ISO 4217, Codes for the representation of currencies and funds
ISO 10962, Securities and related financial instruments — Classification of financial instruments (CFI code)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
fungible
equivalent, substitutable, interchangeable, and not individualized
Note 1 to entry: A fungible financial instrument ranks pari passu in all respects with a different version of the
same financial instrument and can be exchanged into the other version and vice versa at any time.
3.2
ISIN
international securities identification number
alphanumeric code which uniquely identifies a specific security or other financial instrument

4 Principles
4.1 Constituents
The ISIN shall consist of the following:
a) a prefix using the alpha-2 country code specified in ISO 3166, a prefix “XS” as specified in Annex A,
or other prefixes (refer to the Registration Authority website for a complete list of ISIN prefixes);
b) the basic number, which is nine characters (alphanumeric) in length. Where the existing national
number consists of nine characters, this number may be used; where the existing national number
consists of fewer than nine characters, this also may be used, but zeros shall be inserted in front of
the national number. Where a national check digit exists, it shall be regarded as part of the basic
number within the nine characters;
c) a check digit, computed using the modulus 10 “double-add-double” formula as specified in Annex C.
4.2 Financial instruments for which the ISIN is allocated
At a minimum, the ISIN is allocated to financial instruments (see Annex A) identified in ISO 10962 with
the following principles.
a) Equities, debt instruments, entitlements, and structured products
The ISIN is allocated when the financial instrument is negotiable.
b) Derivatives
The ISIN is allocated to those instruments that are traded in their own right, regardless of whether
or not the underlying instrument may have been assigned an ISIN.
c) Referential instruments
The ISIN is allocated to these entities, which are not financial instruments, when they are underlying
or reference assets to financial instruments.
d) Others (combined instruments, other assets)
For the group “combined instruments”, the ISIN is allocated when they are traded. The group “other
assets (insurance policies, real estate deeds, etc.)” may be identified by an ISIN.
