Version 2.1
This Recommended Standard provides two‑letter alphabetic codes which, for the purpose of improving the access to industrial property information, represent, in particular, the names of States, other entities and intergovernmental organizations the legislation of which provides for the protection of industrial property rights or which organizations are acting in the framework of a treaty in the field of industrial property.
The designation of States or other entities in this Recommended Standard does not imply the expression of any opinion whatsoever concerning the legal status of any State or territory, or of its authorities, or concerning the delimitation of its frontiers.
This Recommended Standard is aligned with the universally recognized ISO Alpha‑2 Code contained in International Standard ISO 3166‑1:2006, “Codes for the Representation of Names of Countries and their Subdivisions – Part 1: Country Codes”, published in January 2007 by the International Organization for Standardization (ISO). It is also aligned with the announcements published in ISO 3166–1 Newsletters.
This Recommended Standard is intended to be implemented for any use by industrial property offices requiring the identification of States, other entities and intergovernmental organizations, in coded form.
The recommended codes are contained in Annex A in two sections, organized as follows:
(a) Section 1 presents a list of States, other entities and intergovernmental organizations, in alphabetic sequence of their short names and their corresponding codes;
(b) Section 2 presents the codes referred to in (a) in alphabetic order and the corresponding (short) names of States, other entities and intergovernmental organizations.
ISO has entrusted a Maintenance Agency with the management of International Standard ISO 3166.
WIPO has been granted associate‑member status in the Maintenance Agency and is therefore closely associated with its work. The International Bureau updates this Recommended Standard at intervals following the decisions of the Maintenance Agency and of the respective WIPO body with regard to the inclusion of new two‑letter alphabetic codes or the amending of existing two‑letter alphabetic codes.
To assist users of documents relating to industrial property titles and/or applications therefor, Annex B, Section 1, to this Recommended Standard lists those States for which the code in force prior to January 1, 1978, was subsequently replaced by a new code. A list of States or organizations, with their respective codes, that ceased to exist is given in Annex B, Section 2.
The codes contained in Annex A to this Recommended Standard should be used in all documents relating to industrial property titles and/or applications therefor, even when referring to documents for which a different code existed before January 1, 1978.

[End of Standard]
1 Intergovernmental organizations (regional patent offices) acting for certain Contracting States under the PCT (Patent Cooperation Treaty). In case of the European Patent Office, it also acts as International Searching Authority and International Preliminary Examining Authority under the PCT.(ARIPO, EAPO, EPO, OAPI) or (AP, EA, EP, OA)
2 The Benelux Office for Intellectual Property (BOIP) (former Benelux Trademark and Designs Offices) have replaced the national Offices of Belgium, Luxembourg and the Netherlands with regard to actions relating to marks and industrial designs.(BOIP) or (BX)
3 In the electronic database of the International Register of Marks, the International Bureau of WIPO uses the following additional codes, not part of the active codes of Standard ST.3: “DD” to designate Germany without the territory that, prior to October 3, 1990, constituted the Federal Republic of Germany; “DT” to designate Germany without the territory that, prior to October 3, 1990, constituted the German Democratic Republic.(Germany) or (DE)
4 The code “WO” is used in relation to the international publication under the Patent Cooperation Treaty (PCT) of international applications filed with any PCT receiving Office, as well as in the publication of international deposits of industrial designs under the Hague Agreement Concerning the International Deposit of Industrial Designs. In this regard, reference is made to INID code (33) given in WIPO Standards ST.9 and ST.80. The code “WO” is also the appropriate code to be used with respect to international registrations of marks under the Madrid Agreement and the Madrid Protocol Concerning the International Registration of Marks. The code “IB” is used in relation to the receipt of international applications under the PCT filed with the International Bureau of WIPO in its capacity as a PCT receiving Office.(Intl Bureau, WIPO) or (IB, WO)
5 Provisional name.(Western Sahara) or (EH)
6 Code BF adopted in 1984.
7 Code CD adopted in 1997.
8 Code MM adopted in 1989.
9 Code TL adopted on May 20, 2002.
10 Code SY used before 1.1.1978.
11 Code DL used before 1.1.1978.
12 Subsequent to the country name change of “Yugoslavia” to “Serbia and Montenegro”, that took effect on February 4, 2003, and to the decision by the ISO 3166/MA to use the new country name and new two-letter code “CS” (to replace “YU”), which was announced on July 23, 2003, the SCIT Standards and Documentation Working Group agreed, at its fifth session, in November 11, 2004, to recommend that the two-letter code “YU” continue to be used for “Serbia and Montenegro” in the industrial property field because code “CS” raised certain problems due to its former use to represent “Czechoslovakia” until 1993.
