Several different country codes have been developed over time such as International Organization for Standardization (ISO) codes, Internet Assigned Numbers Authority (IANA) internet codes, United Nations (UN) vehicle codes, International Olympic Committee (IOC) olympic codes, UN/ISO numeric codes, and International Telecommunications Union (ITU) calling codes.
