The flag of the international Olympic movement

The flag of the international Paralympic movement

The International Olympic Committee (IOC) uses three-letter abbreviation country codes^[1] to refer to each group of athletes that participate in the Olympic Games. Each geocode usually identifies a National Olympic Committee (NOC), but there are several codes that have been used for other instances in past Games, such as teams composed of athletes from multiple nations, or groups of athletes not formally representing any nation.

Several of the IOC codes are different from the standard ISO 3166-1 alpha-3 codes. Other sporting organisations like FIFA use similar country codes to refer to their respective teams, but with some differences. Still others, such as the Commonwealth Games Federation or Association of Tennis Professionals, use the IOC list verbatim.

Because French has been the reference language of IOC since 1896, then English, and the host country's language when necessary, most IOC codes have their origins from French or English.^[2]

History

The 1956 Winter Olympics and 1960 Summer Olympics were the first Games to feature Initials of Nations to refer to each NOC in the published official reports.^[3] However, the codes used at the next few Games were often based on the host nation's language (e.g., GIA for Japan at the 1956 Winter Olympics and 1960 Summer Olympics, both held in Italy, from Italian Giappone) or based on the French name for the nation (e.g., AUT for Austria, from Autriche). By the 1972 Winter Olympics, most codes were standardized on the current usage, but several have changed in recent years. Additionally, the dissolution of the Soviet Union, division and unification of Germany, breakup of Yugoslavia, dissolution of Czechoslovakia, and several other instances of geographical renaming have all resulted in code changes.

In addition to this list of over 200 NOCs, the participation of National Paralympic Committees (NPCs) at the Paralympic Games requires standardised IOC codes, such as Macau (or as "Macau, China" since 1999) and the Faroe Islands, coded MAC and FRO respectively.^[4][5]

Current NOCs

There are 206 current NOCs (National Olympic Committees) within the Olympic Movement. The following tables show the currently used code for each NOC and any different codes used in past Games, per the official reports from those Games. Some of the past code usage is further explained in the following sections. Codes used specifically for a Summer Games only or a Winter Games only, within the same year, are indicated by "S" and "W" respectively.

EOR	Refugee Olympic Team from French Équipe olympique des réfugiés	2020	Used for the IOC Refugee Olympic Team at the 2020 Summer Olympics for athletes to compete who have been displaced from their home countries. The IOC code was changed from ROT which was used in 2016.

IOA	Independent Olympic Athletes	2000 2012 2016	Used for Individual Olympic Athletes in 2000,[12] a designation used for athletes from Timor-Leste before the formation of its NOC.

The Netherlands Antilles Olympic Committee's membership from the IOC was withdrawn the previous year, and South Sudan has not formed an NOC. IOA was used again in 2016 for athletes from Kuwait as a result of the suspension of its National Olympic Committee.[14]
