Mail country codes are a set of two-letter alphabetic codes that are used to indicate the country of origin or destination of mail. These codes are an essential part of the international mail system, allowing postal services around the world to efficiently process and deliver mail across borders.
The use of mail country codes began in the 1960s when the Universal Postal Union (UPU) standardized the two-letter codes for each country. The UPU is a specialized agency of the United Nations that coordinates postal policies among member nations and establishes international postal regulations.

The UPU recommends that the mail country code be written in capital letters and placed on the last line of the address, separated from the rest of the address information by at least one space.
