With the agreement of the Administration of the Republic of Serbia, the Director of TSB has assigned the international codes to Kosovo. Kosovo is represented in ITU as Kosovo* which the designation is without prejudice to positions on status, and is in line with UNSCR 1244 and the ICJ Opinion on the Kosovo declaration of independence.
