IW0 Prefix - Italy or Sardinia?

Modified on Fri, 11 Apr, 2014 at 8:00 AM

Some logging programs seem to map all IW0 callsigns to Sardinia, which is incorrect.


The IW0 prefix is allocated as follows:


Callsigns in the range IW0

[A:Z][A:Z] are allocated to the region of Lazio, Italy.
Callsigns in the range IW0[Q:T][A:Z][A:Z] are allocated to the region of Umbria, Italy.
Callsigns in the range IW0[U:Z][A:Z][A:Z] are allocated to Sardinia.


For an in-depth treatment of Italian callsigns, see  I0JX's Almost everything on the Italian ham-radio callsign assignment system.
