World Amateur Radio Prefixes

Radio callsigns for the world are set by the ITU – the UN Agency which coordinates all radio activity.

The ITU allocates a block or blocks of prefixes to each country, and all callsigns must begin with the specified prefix.

This applies to all radio amateurs, aircraft, ships, broadcast, commercial stations etc.

This must be the most comprehensive list I've ever seen in my 18yrs as a Radio Ham.

Many thanks to Rod Dinkins, AC6V, for taking the time to put this together.
