ISO 3166 Countries List

ISO 3166 is a standard published by the International Organization for Standardization (ISO) that defines codes for the names of countries, dependent territories, and special areas of geographical interest. Each country is assigned a two-letter and a three-letter code. For instance, the United States has the two-letter code “US” and the three-letter code “USA.”

Types of ISO 3166 Codes

  1. Alpha-2 code – a two-letter code that represents a country name, recommended as the general purpose code
  2. Alpha-3 code – a three-letter code that represents a country name, which is usually more closely related to the country name
  3. Alpha-4 code – a four-letter code that represents a country name that is no longer in use. The structure depends on the reason why the country name was removed from ISO 3166-1 and added to ISO 3166-3.

List of ISO 3166 certified Countries

What is ISO 3166-1 Code?

ISO 3166-1 is a standard published by the International Organization for Standardization (ISO) that defines codes for the names of countries and their subdivisions. These codes consist of two parts: a two-letter country code (alpha-2) and a three-letter country code (alpha-3). For example:

  1. The alpha-2 code for the United States is “US.”
  2. The alpha-3 code for the United States is “USA.”

What is ISO 3166-2 Code?

ISO 3166-2 is part of the ISO 3166 standard published by the International Organization for Standardization (ISO). It defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. These codes are used for addressing mail, managing regions in databases, and many other purposes.

Each country with its own ISO 3166-1 code is assigned a unique set of ISO 3166-2 codes for its subdivisions. These codes typically consist of the ISO 3166-1 country code followed by a hyphen and a further alphanumeric code to represent the subdivision. For example:

  1. The ISO 3166-2 code for California in the United States is “US-CA.”
  2. The ISO 3166-2 code for Ontario in Canada is “CA-ON.”

Can Country names be removed from ISO 3166-1?

Yes, Country names might be removed from ISO 3166-1 for various reasons-

  1. A country might change a significant part of its name, for example, Burma (BU) was changed to Myanmar (MM) in 1989. The code element for the formerly used country name is therefore BUMM.
  2. A country may be divided into two or more new ones, for example, Czechoslovakia was divided into Czech Republic and Slovakia in 1993. The code element for the formerly used country name Czechoslovakia is CSHH, HH meaning that no single successor country exists.
  3. Two or more countries may merge for example Democratic Yemen (YD) and Yemen Arab Republic (YE) merged into the Republic of Yemen (YE) in 1990. The code element used for the formerly used country name Democratic Yemen is YDYE.

Benefits of ISO 3166 Certification

ISO 3166 certification offers numerous benefits to countries and territories, including:

  4. Enhanced Data Management: ISO 3166 certification aids in efficient data management by providing unique identifiers for countries, improving data accuracy and integrity.
  5. Interoperability: Standardized country codes promote interoperability between different systems and databases, ensuring smooth integration and communication.

Conclusion

ISO 3166 certification plays a crucial role in facilitating global communication, trade, and data management. Certified countries benefit from standardized representation, enhanced interoperability, and improved international recognition. As the world becomes increasingly interconnected, ISO 3166 certification remains essential for seamless integration into the global community.
