While Azores islands count for a single DXCC entity, they offer three IOTA groupings, as follows:
- EU-003 Eastern Azores Group [CU1 (Santa Maria Island), CU2 (São Miguel Island)]
36.83N – 38.00N / 24.5W – 26.5W
- EU-089 Western Azores Group [CU8 (Flores Island), CU9 (Corvo Island)]
39.25N – 39.83N / 31W – 31.33W
- EU-175 Central Azores Group [CU3 (Terceira Island), CU4 (Graciosa Island), CU5 (São Jorge Island), CU6 (Pico Island), CU7 (Faial Island)]
38.00N – 39.25N / 26.5W – 29W
I live in Pico Island (CU6) and my IOTA reference is EU-175.
