ITU prefix (original) (raw)
The ITU allocates callsign prefixes for radio stations. These prefixes are agreed upon internationally. A callsign can be any number of letters and digits but each country must only use callsigns that begin with the characters allocated for use in that country.
Of the second and or third letter of the prefix in the list below, if the country 'owns' all of A to Z in that position, then that country can also use the digits 0 to 9 in that position.
E.g. The USA owns KAA - KZZ so can also use prefixes like KA1 KP4 K5 K9 and so on.
The USA also owns AAA - ALZ so can use AL4 AL8 etc but can NOT use A4 or A9 because they do not own the whole of AA to AZ they only have AA to AL.
