Call-Sign History

Call-Sign History by Country

INTERNATIONAL CALL-SIGN PREFIX SERIES ALLOCATIONS

These are de jure official ITU allocations. There has been no attempt to show de facto usage in this list. Countries have often deviated from their official call-sign allocations. The prefixes shown here are for use by all classes of stations.

The dates shown are those of allocation. Typically it takes 2-5 years for call-sign changes to be implemented. Prior to 1912, there was no international coordination of call-sign assignments. Provisional use in italics. Prior to 1927, most amateur or experimental stations did not use international prefixes.

Latest changes :
2015 : Niue allocated E6.
2012 : Kosovo self-allocated Z6. Not yet recognized by ITU.
2011 : South Sudan allocated Z8.
2007 : Cook Islands allocated E5.
2007 : Bosnia & Herzegovina T9 changed to E7.
