Country codes are short numeric or alphabetical geographical codes that have been developed for data processing and communications around the world. They represent countries and/or dependent areas and are sometimes referred to as geocodes.

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.
