These provinces correspond to the historic divisions of Uthuru Boduthiladhunmathi, Dhekunu Boduthiladhunmathi, Uthuru Medhu-Raajje, Medhu-Raajje, Dhekunu Medhu-Raajje, Huvadhu (or Uthuru Suvadinmathi), and Addumulah (or Dhekunu Suvadinmathi).
The Maldives has twenty-six natural atolls and few island groups on isolated reefs, all of which have been divided into twenty-one administrative divisions (twenty administrative atolls and Malé city).
In addition to a name, every administrative division is identified by the Maldivian code letters, such as "Haa Alif" for Thiladhunmati Uthuruburi (Thiladhunmathi North); and by a Latin code letter.
The first corresponds to the geographical Maldivian name of the atoll. The second is a code adopted for convenience. It began in order to facilitate radio communication between the atolls and the central administration.
As there are certain islands in different atolls that have the same name, for administrative purposes this code is quoted before the name of the island, for example: Baa Funadhoo, Kaafu Funadhoo, Gaafu-Alifu Funadhoo.
Since most Atolls have very long geographical names it is also used whenever the long name is inconvenient, for example in the atoll website names.
This code denomination has been very much abused by foreigners who did not understand the proper use of these names and have ignored the Maldivian true names in publications for tourists.
Maldivians may use the letter code name in colloquial conversation, but in serious geographic, historical or cultural writings, the true geographical name always takes precedence.
The Latin code letter is normally used in boat registration plates. The letter stands for the atoll and the number for the island.
Each atoll is administered by an Atoll Chief (Atholhu Veriyaa) appointed by the President.
The Ministry of Atoll Administration and its Northern and Southern Regional Offices, Atoll Offices and Island Offices are collectively responsible to the President for Atolls Administration.
The administrative head of each island is the Island Chief (Katheeb), appointed by the President. The Island Chief's immediate superior is the Atoll Chief.
The introduction of code-letter names has been a source of much puzzlement and misunderstandings, especially among foreigners. Many people have come to think that the code-letter of the administrative atoll is its new name and that it has replaced its geographical name.
Under such circumstances it is hard to know which is the correct name to use.
