Lists of countries and regions and their annual changes

The country classification is based on the Commission Regulation 1106/2012 on the country classification of the statistics on the Community external trade and the trade between the Member States. With a few exceptions (XK Kosovo, XS Serbia, XC Ceuta and XL Melilla), the  classification complies with the so-called ISO alpha standard (ISO 3166) having two-letter country identifications.
