ISO 3166 country codes added to the JFSC appendix D2.  


The JFSC has also introduced International Organization for Standardization (ISO 3166) country codes so you can quickly determine regions that are not designated.

The International Standard for country codes and codes for their subdivisions

The purpose of ISO 3166 is to define internationally recognised codes of letters and/or numbers that we can use when we refer to countries and their subdivisions. However, it does not define the names of countries – this information comes from United Nations sources (Terminology Bulletin Country Names and the Country and Region Codes for Statistical Use maintained by the United Nations Statistics Divisions).

Using codes saves time and avoids errors as instead of using a country’s name (which will change depending on the language being used), we can use a combination of letters and/or numbers that are understood worldwide. For example,

  • All national postal organisations worldwide exchange international mail in containers identified with the relevant country code.
  • Internet domain name systems use codes to define top-level domain names, such as
    • “.fr” for France and
    • “.au” for Australia.
  • In addition, in machine-readable passports, the codes are used to determine the nationality of the user, and
  • When we send money from one bank to another, the country codes are a way to identify where the bank is based.

The APPENDIX D2 ISO additions are shown in the following extract

ISO 3166 has three parts: codes for countries, codes for subdivisions and formerly used codes (once used to describe countries but no longer in use).

The country codes can be represented either as

  • A two-letter code (alpha-2) which is recommended as the general-purpose code,
    • For example
      • ID-RI is the Riau province of Indonesia and
      • NG-RI is the Rivers province in Nigeria.
  • A three-letter code (alpha-3), which is more closely related to the country name, and a three-digit numeric code (numeric-3), which can be helpful if you need to avoid using Latin script.

The codes for subdivisions are represented as the alpha-2 code for the country, followed by up to three characters.

Names and codes for subdivisions are usually taken from relevant official national information sources.
