The International Olympic Committee (IOC) uses three-letter abbreviation country codes to call each group of athletes that participate in the Olympic Games.
Since 1952, the list of International Olympic Committee (IOC) country codes has evolved as new nations joined and political borders shifted. Many countries have changed their codes due to name updates or geographical restructuring.
Key Facts About Code Changes
- Total Representation: There are currently 206 National Olympic Committees (NOCs) recognized by the IOC.
- Frequent Updates: Codes often change to reflect a nation's preferred name or language, such as the Ivory Coast switching from IVC (1964) and CML (1968) to its current French-based code, CIV (Côte d'Ivoire).
- Multiple Code Histories: Some nations have cycled through several identifiers. For example, the Democratic Republic of the Congo has used COK (1968) and ZAI (1972–1996) before settling on COD.
- Obsolete Codes: At least 21 codes are now considered obsolete, representing former territories or dissolved nations like the Netherlands Antilles (AHO).
- Recent Additions: New sovereign states continue to be added, with Kosovo (2014) and South Sudan (2015) being two of the most recent members.
