Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
(IS0 member bodies). The work of preparing International
national standards bodies
Standards is normally carried out through IS0 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 6166 was prepared by Technical Committee ISO/TC 68,
Banking.
This fourth edition cancels and replaces the third edition (IS0 6166 : 19861, of which it
constitutes a minor revision.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
Annexes A, B, C, D, E, F and G form an integral part of the standard. Annex H is for
information only.

IS0 6166 : 1987 (E)
Introduction
With the rapid expansion of international securities business the need for a universally
applicable International Securities Identification Number (ISIN) has become increas-
ingly urgent.
No world-wide numbering system exists at the time of the publication of this Interna-
tional Standard. A great number of countries with highly developed securities business
identify issues of securities by means of code numbers, which are without any
significance outside the country concerned. Securities of the same issue, in other
words, are identified by means of different numbers in the country where they are
physically held and/or booked. As a result, the national numbers cannot be applied in
cross-border transactions.
Because of its strong rationalization effect, the introduction of an internationally
applicable numbering system would substantially facilitate and support international
securities business. Such a system is provided by 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 introduction of the
new system. Moreover, it is aimed to create a system which is easy to apply interna-
tionally and to establish an information network which ensures that the required infor-
mation can be obtained world-wide immediatelv.
It is understood that some users may not, for practical reasons, be in a position to im-
plement this International Standard immediately. In order for the International Stan-
dard to fulfil its objective, users are however recommended to implement it as soon as
possible and not later than five years after the date of the first edition.’)
