Expanding ISO 3166 to Include Non-UN Member States: Fostering Global Recognition and Cooperation

The International Organization for Standardization (ISO) 3166 standard defines codes for the representation of names of countries and their subdivisions. This widely recognized standard plays a crucial role in facilitating international communication and data exchange.

However, the ISO 3166 list currently only includes countries that are members of the United Nations (UN). This exclusion of non-UN member states can lead to challenges in identifying and referring to these countries in various contexts.

Benefits of Expanding ISO 3166 to Include Non-UN Member states

Expanding the ISO 3166 list to include non-UN member states would bring several significant benefits:

  • Enhanced Global Recognition: By assigning ISO 3166 codes to non-UN member states, these countries would gain formal recognition within the international community. This recognition would enhance their visibility and facilitate their participation in global initiatives and agreements.
  • Improved Data Management and Exchange: The inclusion of non-UN member states in ISO 3166 would standardize the way these countries are represented in data management systems and communication protocols. This standardization would improve the accuracy and consistency of data exchange across borders.
  • Promoted Cross-Border Cooperation: The use of ISO 3166 codes can foster collaboration between countries, regardless of their UN membership status. By providing a common language for identifying and referring to non-UN member states, ISO 3166 can promote cross-border cooperation in various areas, such as trade, development, and cultural exchange.

Addressing Concerns and Ensuring Inclusiveness

Expanding ISO 3166 to include non-UN member states would require careful consideration of potential concerns and ensure that the process is inclusive and transparent. Some key considerations include:

Ensuring Consensus and Legitimacy
The inclusion of non-UN member states should be based on a consensus among ISO 3166 stakeholders, including national standards bodies and relevant international organizations. This consensus-building process would ensure the legitimacy and acceptance of the expanded list.

Establishing Clear Criteria for Inclusion
Clear and objective criteria should be established to determine which non-UN member states are eligible for inclusion in ISO 3166. These criteria should align with the principles of international recognition, statehood, and self-determination.

Facilitating Participation from Non-UN Member States
The process of expanding ISO 3166 should actively involve non-UN member states. Their input and perspectives should be considered throughout the decision-making process, ensuring that the expanded list reflects their needs and interests.


Expanding the ISO 3166 list to include non-UN member states would be a significant step towards fostering global recognition, improving data management, and promoting cross-border cooperation. By addressing concerns and ensuring an inclusive approach, the international community can harness the power of ISO 3166 to create a more comprehensive and representative framework for identifying and referring to all countries in the world. For this reason we now have ISO3166 Plus.
