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 (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).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 46, Information and documentation, in

collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/SS

F17, Administrative documents, in accordance with the Agreement on technical cooperation between

ISO and CEN (Vienna Agreement).

This fourth edition cancels and replaces the descriptive text of the third edition (ISO 3166-1:2013),

which has been technically revised.
The main changes compared to the previous edition are as follows.
— The codes have been moved to the database format

— The components of the codes have been defined by descriptors, not by column or line numbers.

— The status of each alpha-2 country code element has been made explicit, as it is the main resource

managed by ISO 3166/MA, necessary for traceability over time.

— All characters in the database, specifically those with diacritical marks, have been checked with the

Universal Coded Character Set, ISO/IEC 10646, and are used consistently.

— The database encoding is UTF-8 (Universal Character Set Transformation Format - 8 bits) from

ISO/IEC 10646, and the same has been used in many applications.

— The three parts — three codes — belong to the same database, updates are done only once for

all parts.
A list of all parts in the ISO 3166 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user's national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

Introduction

The initial edition of the International Standard ISO 3166 was prepared by Technical Committee

ISO/TC 46 in collaboration with the following International Organizations: Customs Cooperation

Council (CCC), [since 1995: World Customs Organization (WCO)], United Nations Economic Commission

for Europe (ECE), Food and Agriculture Organization of the United Nations (FAO), International

Atomic Energy Agency (IAEA), International Air Transport Association (IATA), International Chamber

of Commerce (ICC), International Chamber of Shipping (ICS), International Federation of Library

Associations (IFLA), International Labour Office (ILO), International Telecommunication Union (ITU),

International Union of Railways (UIC), United Nations Organization (UN), United Nations Conference

on Trade and Development (UNCTAD), Universal Postal Union (UPU), World Intellectual Property

Organization (WIPO), and World Health Organization (WHO).

ISO 3166 was first published in 1974, subsequent editions in 1981, 1988 and 1993. In 1997, it was

divided into three parts.
— Editions of ISO 3166-1: ISO 3166-1:1997, ISO 3166-1:2006, ISO 3166-1:2013.
— Editions of ISO 3166-2: ISO 3166-2:1998, ISO 3166-2:2007, ISO 3166-2:2013.
— Editions of ISO 3166-3: ISO 3166-3:1999, ISO 3166-3:2013.

The ISO 3166 series provides universally applicable coded representations of names of countries

(current and non-current), dependencies, and other areas of particular geopolitical interest and their

subdivisions.

ISO 3166-1 establishes codes that represent the current names of countries, dependencies, and other

areas of particular geopolitical interest, on the basis of country names obtained from the United

Nations.

ISO 3166-2 establishes a code that represents the names of the principal administrative divisions, or

similar areas, of the countries and entities included in ISO 3166-1.

ISO 3166-3 establishes a code that represents non-current country names, i.e. the country names

deleted from ISO 3166 since its first publication in 1974.

The ISO 3166 series do not express any opinion whatsoever concerning the legal status of any country,

dependency, or other area named herein, or concerning its frontiers or boundaries.

The 2013 edition of the ISO 3166 series has been the last one published as paper standard, with the

descriptive text, and the codes together.

At the end of 2013, the split had happened: ISO 3166 codes have been moved to the database format

(de facto merging three contents together), with access from ISO Online Browsing Platform, while the

descriptive text has been awaiting updates.

This 2020 edition of the ISO 3166 series includes an update of the descriptive text (description of the

codes) from 2013, for each of three parts. It takes into account the stricter database rules imposed on

the code itself, as opposed to paper documents.

The International Standard ISO 3166 has been the very first ISO achievement of the concept of "standard

as a database", implemented in the end of 2013. The ISO OBP (Open Browsing Platform) is an application

to visualise ISO3166 codes on the web interface, the data being stored in the unseen database.

The International Standard ISO 3166, for each of its three parts - three codes - is formed of two

components: documented description of its content, and its related content inside a database.

Both terms "this document" and "the code corresponding to this document" are used throughout this

2020 edition of the ISO 3166 series.
