The prefix Z6 now is listed as Kosovo (No DXCC Status) as it is not a legal ITU/IARU prefix. It is listed as INACTIVE as it is not recognized by the ARRL for DXCC purposes.
A few other Award program accept this prefix. However, the country file for Log4OM is based entirely on the DXCC list from the ARRL.
