YO stands for "Former Yugoslavia NATO Country Code Obsolete 1993." This designation was used in NATO communications to identify the former Yugoslav Republic prior to its dissolution and the subsequent establishment of independent nations. Since 1993, the code has been rendered obsolete, reflecting the geopolitical changes in the region as the former Yugoslavia fragmented into several sovereign states.
