ItalyI7: Puglia and Basilicata
Callsigns beginning with I7 were issued in Puglia, Basilicata, in Italy. The same area appears in the series IK7, IZ7, IW7, IU7, IQ7.
Call area
Every I7 station counts for CQ zone 15 and ITU zone 28.
How call areas work in Italy
Italian calls carry the region in the digit: I1 Piemonte and Liguria, I2 Lombardia, I3 Veneto, I4 Emilia-Romagna, I5 Toscana, I6 Marche and Abruzzo, I7 Puglia and Basilicata, I8 Campania, Molise and Calabria, I0 Lazio and Umbria. The IK, IZ, IW, IU and IQ series follow the same digits.
The special-statute regions have prefixes of their own: IX1 Valle d'Aosta, IN3 Trentino-Alto Adige, IV3 Friuli-Venezia Giulia and IT9 Sicily, which counts as Italy for DXCC. Sardinia (IS0, IM0) is a separate entity. All of Italy is in CQ zone 15 and ITU zone 28; the area matters for national awards and in the ARI DX Contest, where Italians send their province.
Portable and moved stations
Operators away from home often add a suffix such as /P or the number of the area they are in, and many keep a I7 call after moving. For awards the place of operation counts, so the prefix is a strong hint, not proof.
