Kaafu Atoll is an administrative division of the Maldives. It consists of Kaashidhoo Island, Gahaafaru Atoll, and Malé Atoll (which includes the North Malé Atoll and the South Malé Atoll). It also has a number of uninhabited islands. Malé, capital of the Maldives is naturally located within the North Malé Atoll, but it is not part of the Kaafu administrative division. NOTE: Haa Alifu, Haa Dhaalu, Shaviyani, Noonu, Raa, Baa, Kaafu, etc. are code letters assigned to the present administrative divisions of the Maldives. They are not the proper names of the natural atolls that make up these divisions. Some atolls are divided into two administrative divisions while other divisions are made up of two or more natural atolls. The order followed by the code letters is from North to South, beginning with the first letters of the Thaana alphabet used in Dhivehi. These code letters are not accurate from the geographical and cultural point of view. However, they have become popular among tourists and foreigners in the Maldives who find them easier to pronounce than the true atoll names in Dhivehi, (save a few exceptions, like Ari Atoll) ( source Wikipedia )
