Updates: 

As of 2022-02-15, a new capital city will be constructed. It has been named Nusantara (Formally Capital City of Nusantara, in Indonesian Ibu Kota Nusantara).

"Geopolitical Entities, Names, and Codes, Edition 2" (GENC), a U.S. standard that's supposed to correspond to ISO 3166-2, was issued on 2014-03-31. It gives Kalimantan Utara the code ID-KU. On 2014-10-30, ISO issued that same code for Kalimantan Utara, and simultaneously updated the code for the geographical unit Papua (two provinces) from ID-IJ to ID-PP.

Update 12 to Geopolitical Entities and Codes (formerly FIPS 10-4) is dated 2013-06-30. It assigns a code to the new province of Kalimantan Utara. The code for Kalimantan Timur, from which it was split, remains unchanged.

Update 10 to Geopolitical Entities and Codes is dated 2012-12-31. It merely changes the spelling of the Indonesian word for "province" from "propinsi" to "provinsi".

Cenderawasih province has been proposed. It would consist of the districts of Biak, Mamberamo, Serui, Supiori, and Waropen, from Papua province. Its capital would be Serui. Its name is also the name of a bay, which is the same as the local name for the bird of paradise.

Valentin Poposki called it to my attention that North Kalimantan province is being split from East Kalimantan (source [8]). This split has been contemplated at least since 2004. The new provincial government should be formed by the end of 2013.

There's talk that Indonesia might adopt a uniform nationwide time zone in 2013. The time would be UTC+8, currently the central zone of Sulawesi and Bali. This plan has not been confirmed yet.

ISO 3166-2 Newsletter II-3 is dated 2011-12-15. It changes the code for Maluku as a geographical unit (formerly ID-MA), to avoid duplicating the code for Maluku as a province.

ISO 3166-2 Newsletter number II-1, dated 2010-02-03, changes the name of one of the geographical units from Irian Jaya to Papua, and assigns an ISO code to Papua Barat province.

FIPS Publication Change Notice No. 10, affecting FIPS PUB 10-4, was issued on 2006-03-23. It lists new codes resulting from the creation of three provinces (Irian Jaya Barat, Kepulauan Riau, and Sulawesi Barat).

On 2004-09-22 the DPR (Parliament) approved the creation of a new province, Sulawesi Barat (West Sulawesi). ISO 3166-2 Newsletter number I-7 was published on 2005-09-13. It assigns an ISO code to Sulawesi Barat.

ISO 3166-2 Newsletter Number I-6 was published on 2004-03-08. It shows the new status of Aceh as an autonomous province, with no name change. It also shows the new province of Kepulauan Riau.

On 2003-01-27, President Megawati Sukarnoputri signed Presidential Instruction No. 1, dividing Papua into three provinces: Central Papua (Papua Tengah), Papua (or East Papua - Papua Timur), and West Papua (Papua Barat). The capital of the original Papua province, Jayapura, would remain the capital of East Papua province. The capital of Central Papua would be Timika, and of West Papua, Manokwari. West Papua would consist of Fak-Fak, Manokwari, and Sorong regencies. Central Papua would comprise six regencies, including Mimika. The local government of West Papua province was set up on 2003-02-06. The central government approved the appointment of a governor on 2003-11-14, which makes the new province official. Central Papua was supposed to be created on 2003-08-23, but violent protests forced the government to delay the action. As of this writing, it appears that the creation of Central Papua has been shelved. Many Papuans are using the name "Port Numbay" for the capital, instead of Jayapura.

Proposals for new provinces include dividing Sumatera Utara into two provinces named Tapanuli and Sumatera Timur; splitting a new Cirebon province from Jawa Barat; splitting Madura from Jawa Timur; splitting Ketapang from Kalimantan Barat; splitting Southeast Maluku from Maluku; splitting Bima from Nusa Tenggara Barat; splitting Flores from Nusa Tenggara Timur; splitting Luwu Raya from Sulawesi Selatan; splitting Sulawesi Timur from Sulawesi Tengah; and splitting Tomini Raya from Sulawesi Utara.

Change Notice 4 to FIPS PUB 10-4 is dated 2000-02-25. Timor Timur, as a province of Indonesia with FIPS code ID27, has been deleted from the standard. In its place, a country code of TT has been assigned to East Timor.

On 1999-09-16, a bill was passed to split Maluku Utara (North Moluccas) province from Maluku. Change Notice 6 to FIPS PUB 10-4, dated 2001-01-28, shows this change.

Also on 1999-09-16, the Indonesian parliament voted to split Irian Jaya into three provinces: Papua (Irian Jaya Timur), Irian Jaya Barat, and Irian Jaya Tengah. However, the split was not ratified by the local authorities, so it never took place. A Presidential Instruction in 2003 directed the Home Minister to take steps to implement the two new provincial governments, but many Papuans argue that the special autonomy bill of 2001 supersedes and voids the bill of 1999.

ISO 3166-2 Newsletter Number I-2 is dated 2002-05-21. It shows the changes to the provinces of Indonesia that occurred in 1999-2000. It assigns codes to the new provinces, which are shown in the table below. It also gives "Papua Barat" as an alternate name for the region (or geographical unit) named Irian Jaya; however, the province formerly known as Irian Jaya is now named Papua, with no alternate name. Newsletter Number I-4, dated 2002-12-10, shows the name of Irian Jaya, as a geographical unit, also changing to Papua.

Change Notice 7 to FIPS PUB 10-4 is dated 2002-01-10. It lists new codes resulting from the splitting of three provinces. Change Notice 8, dated 2002-06-28, shows the name of Irian Jaya, as a province, changing to Papua.

At the beginning of the 20th century, Indonesia was a newly coined name. It referred in a general way to the southern part of the Malay Archipelago. The modern country of Indonesia was then several Dutch colonies, known collectively as the Netherlands Indies or the East Indies. During World War II, the area was almost completely occupied by Japanese forces. At the end of the war, the country declared its independence under the name of Indonesia. On 1949-12-27, the separation became official. Dutch New Guinea, however, remained a colony of the Netherlands until 1963-05-01. Indonesia unilaterally annexed Portuguese Timor in 1976. After some struggle, it regained its independence in 2002 and became Timor-Leste.

Primary subdivisions: 

Indonesia is divided into 31 propinsi (provinces), a daerah istimewa (special region), an autonomous province, and a daerah khusus ibukota (special district). There are indications that the official spelling of the Bahasa Indonesia word for province is changing to provinsi.

Province: except for Aceh autonomous province, Yogyakarta special region, and Jakarta Raya special district. HASC: Hierarchical administrative subdivision codes. These are based on the province codes from ISO standard 3166-2, but have been altered for the four new provinces and their parents. ISO: Codes from ISO 3166-2. For full identification in a global context, prefix "ID-" to the code (ex: ID-RI represents Riau). GEC: Codes from GEC. Code: These codes seem to be used regularly in Indonesia, but I haven't found a name for them. Postcode: Indonesian postal codes are five digits. They are known as SKPI, for Sistem Kode Pos Indonesia; or Kodepos for short. The first two digits determine the province, as shown. Tz: Time zone for the province, in hours later (+) than UTC. No daylight saving time observed. Population: 2010-05-15 census (source [13]). Area: The area and population of Kalimantan Utara are included in Kalimantan Timur; of Papua Barat in Papua; of Kepulauan Riau in Riau; and of Sulawesi Barat in Sulawesi Selatan. Capital: Source [11] says, "The modern provincial capital of Jambi consists of the old prewar centre, seat of the former sultanate Jambi, and the new governmental centre in Telanaipura just west of it." Maps usually show one city, labeled either "Jambi" or "Jambi (Telanaipura)". Reg: Geographical unit containing the province, according to ISO 3166-2. For key to codes, see table below.

Further subdivisions:

See the Regencies of Indonesia page.

The provinces are subdivided into kabupaten (regencies, or districts) and kotamadya (municipalities). The districts are further subdivided into kecamatan (sub-districts). ISO 3166-2 lists seven "geographical units". Basically, these are the major islands or island groups of Indonesia. They have no official standing, but are obvious groupings on a map.

Change history: 

1. 1900: Indonesia consisted of the Dutch colonies of Borneo, Celebes, Java, Moluccas, New Guinea, and Sumatra, and the Portuguese colony of Timor (actually occupying about half of the island of Timor, and some smaller nearby islands). Some of the colonies had divisions or residencies. Borneo's West Division was the same as Kalimantan Barat; the other three provinces on the island made up the South and East Division. Celebes was divided into Celebes, Menado, and Ternate divisions in this period. At the time of independence, Sumatra was divided into the residencies of Atjeh, Benkoelen, Djambi, Lampongs, Oostkust, Palembang, Tapanoeli, and Westkust.
2. 1950-08-15: New provisional constitution changed the name of the country from United States of Indonesia to Republic of Indonesia, and divided it into ten provinces, whose English names were Borneo, Celebes, Central Java, Central Sumatra, East Java, Lesser Sunda Isles, Moluccas, North Sumatra, South Sumatra, and West Java. Capital renamed from Batavia to Jakarta.
3. 1950: Yogyakarta special region split from Jawa Tengah (Central Java) province.

10. 1963-05-01: Irian Barat became a province of Indonesia.
11. 1964: Lampung province split from Sumatera Selatan; Sulawesi Tengah province split from Sulawesi Utara; Sulawesi Tenggara province split from Sulawesi Selatan.
12. ~1966: Name of capital of Aceh changed from Kutaradja to Banda Atjeh; name of capital of Irian Barat changed from Kotabaru to Sukarnapura; name of capital of Jambi changed from Jambi to Telanaipura; capital of Riau moved from Tandjungpinang to Pekanbaru; capital of Sumatera Barat moved from Bukittinggi to Padang.

14. 1969: Name of capital of Irian Barat changed from Sukarnapura to Jayapura.
15. 1971: Name of capital of Sulawesi Selatan changed from Makassar to Ujung Pandang.
16. 1972-08-17: Spelling reform inaugurated by presidential decree. Name of Djakarta changed to Jakarta. Other name changes followed at intervals. The change was supposed to be completed by 1973-01-01. The purpose was to align Indonesian spelling with Malaysian. Other displaced spellings were Atjeh (changed to Aceh), Djambi (Jambi), and Djawa (Jawa) in province names, Djajapura (Jayapura), Surabaja (Surabaya), Bandjarmasin (Banjarmasin), Palangkaraja (Palangkaraya), Tandjungkarang (Tanjungkarang), and Udjung (Ujung) in capital names.
17. 1973: Name of Irian Barat province changed to Irian Jaya.
18. ~1974: Sulawesi Selatan province (capital Ujung Pandang) split into Sulawesi Selatan and Sulawesi Tenggara; Sulawesi Utara province (capital Manado) split into Sulawesi Tengah and Sulawesi Utara; Bengkulu and Lampung provinces split from Sumatera Selatan; territory transferred from Jambi to Sumatera Barat, depriving Jambi of access to the west coast.
19. 1976-07-17: Indonesia annexed Portuguese Timor as Loro Sae province.
    
20. ~1977: Capital of Kalimantan Tengah moved from Pahandut to Palangkaraya; name of Loro Sae province changed to Timor Timur (East Timor).

As part of Indonesia, its HASC code had been ID.TT, ISO TT, GEC ID27, and it had been in the Nusa Tenggara geographical unit.
30. 2002-09-24: Kepulauan Riau province split from Riau (former HASC code ID.RI, GEC code ID19). It consists of the kabupaten of Karimun, Kepulauan Riau, Lingga, and Natuna, and the kotamadya of Batam and Tanjung Pinang, and its capital is Tanjung Pinang. The government of the new province was inaugurated on 2004-07-01. It met temporarily in Batam until the capital was ready.
31. 2003-11-14: Irian Jaya Barat, or Papua Barat, or West Papua province split from Papua (former HASC code ID.IJ, GEC code ID09). See source [2] for more details.

Other names of subdivisions: 

In most Western European languages, the names for the islands of Sumatera, Kalimantan, Jawa, and Sulawesi, respectively, are Sumatra, Borneo (French: Bornéo), Java (Turkish: Cava), and Celebes (French: Célèbes, Portuguese: Célebes, Turkish: Selebes). Nusa Tenggara is sometimes translated as Lesser Sunda Islands (French: Îles de la Sonde), and Maluku used to be better known in the West as the Molucca Islands. If province names are translated, it's usually only by translating the name of one of those islands and a compass point. Barat is West, Selatan is South, Tengah is Central, Tenggara is Southeast, Timur is East, and Utara is North. For example, German for Sumatera Barat is Westsumatra; Italian for Jawa Tengah is Java centrale; Portuguese for Sulawesi Utara is Célebes Setentrionais or Célebes do Norte. See the table of compass points in the introduction to the book "Administrative Subdivisions of Countries".

The Digital Atlas of Indonesian History (source [12]) has a page that explains some of the spelling inconsistencies found in Indonesian place names.
