Yugoslavia, Federal Republic of
No Scott number
These are obligatory postal tax stamps that were used from June 1 to July 30. The total print run was 3,500,000 stamps. Although Serbia was part of the Federal Republic of Yugoslovia in 2000, it was semi-autonomous and released a number of its own stamps. Because the stamps were only used in the region of Serbia rather than nationwide, they are not eligible for Scott catalog numbers.
