List of IOC country codes (2024)

The International Olympic Committee (IOC) uses three-letter abbreviation country codes to refer to each group of athletes that participate in the Olympic Games. Each code 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, such as 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.

History

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.

Two other significant code changes have occurred, both because of a change in the nation's designation as used by the IOC:

• HOL was changed to NED for the Netherlands for the 1992 Games, reflecting the change in designation from Holland.
• IRN was changed to IRI for Iran for the 1992 Games, reflecting the change in designation to Islamic Republic of Iran.

EUA	United Team of Germany	1956–1964	Used in the IOC's medal database to identify the United Team of Germany, composed of athletes representing the NOCs of both East Germany and West Germany for the 1956–1964 Games. At the time, the team was simply known as Germany in the official reports for those six Games.

IOP	Independent Olympic Participants	1992 2014	Used for Independent Olympic Participants at the 1992 Summer Olympics as a designation used for athletes from FR Yugoslavia who could not compete as a team due to United Nations sanctions.

The Netherlands Antilles Olympic Committee's membership from the IOC was withdrawn the previous year, and South Sudan has not formed an NOC.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.
