The purpose of ISO 3166 is to define internationally recognized codes of letters and/or numbers that we can use when we refer to countries and their subdivisions.
Using codes saves time and avoids errors as instead of using a country's name (which will change depending on the language being used), we can use a combination of letters and/or numbers that are understood all over the world.
The country codes are subject to periodic change so we no longer reference the codes directly in this document.
