Updates: 
Update 8 to Geopolitical Entities and Codes, the successor to FIPS standard 10-4, is dated 2012-05-01. It assigns codes to the
two subdivisions that were missing them.
FIPS Publication Change Notice No. 9, affecting FIPS PUB 10-4, was issued on 2004-10-01. It shows the change of the name of
Leninobod oblast to Sogd.
Dushanbe is administratively separate from the Regions of Republican Subordination, but geographically surrounded by it. ISO
probably intends it to be treated as part of R.R.S. When R.R.S. included Dushanbe, its HASC code was TJ.KR.
ISO/DIS 3166-2 (draft international standard) was published in late 1996, and didn't list any subdivisions of Tajikistan. After
comments, the actual standard ISO 3166-2 was published (1998-12-15). It now showed three regions (Karategin, Khatlon, and
Leninabad) and one autonomous region (Gorno-Badakhshan). Its fourth update, ISO 3166-2 Newsletter number I-4 (2002-12-10),
changed the name of Leninabad region to Sughd. It also deleted Karategin region, without providing a replacement. It confessed
that the "Regions of Republican Subordination" is now bereft of a code. The Tajik authorities have been contacted for better
information.

In 1900, the territory that now constitutes Tajikistan was partly in the Khanate of Bukhara, and partly in the Ferghana,
Pamir, and Zarafshan regions of the Turkestan general government of the Russian Empire. During the Russian Revolution, the
status of the Central Asian lands was unresolved for a time. The Turkestan A.S.S.R. was formed in 1921. In 1924, the Central
Asian part of the Soviet Union was reorganized to correspond to the distribution of nationalities. The Tadzhikskaya Associated
Soviet Socialist Republic was created then. It became a constituent republic of the Soviet Union in 1929. As the Soviet Union
broke up, it became Tajikistan, an independent country, on 1991-09-09.

Postal codes: 
Tajikistan uses six-digit postal codes. The first two digits indicate the region, and the middle two indicate the raion.
These codes are left over from the Soviet regime, and all begin with '7'.
Further subdivisions:
See the Raions of Tajikistan page.
Tajikistan is subdivided into 62 raions, 14 cities, and two hukumats (city councils).
Territorial extent: 
Sogd includes an exclave around the town of Vorukh, surrounded by Kyrgyzstan; and another exclave northwest of Kokand,
in Uzbekistan. There is also a very small portion of Tajikistan enclaved within Kyrgyzstan north of Isfana.
Origins of names: 
- Dushanbe: = Monday (from market day)
Change history: 
- 1920-10-05: Khanate of Bukhara became a Soviet Republic.
- 1921-04-11: Turkestan A.S.S.R. formed from Amu-Darya, Ferghana, Pamir, Samarkand, Semirechensk, and Syr Darya regions, and
the southern part of Transcaspian.
- 1924-10: Turkestan A.S.S.R. and Bukhara reorganized into several units, one of which was the Uzbekskaya S.S.R. The
Tadzhikskaya A.S.S.R., in turn, was part of the Uzbekskaya S.S.R.
- 1927: Gorno-Badakhshanskaya A.Obl. formed.
- 1929-10-15: Tadzhikskaya A.S.S.R. split from Uzbekskaya S.S.R., and its status changed to S.S.R. Name of country's capital
changed from Dyushambe to Stalinabad.
- 1936: Name of Khodjent and its capital changed to Leninabad.
- 1950: Divisions were Gorno-Badakhshan A.Obl., Gharm Oblast, Kulyab Oblast, Leninabad Oblast, and the rest of Tadzhikskaya
S.S.R. around Dushanbe. Gharm is now eastern Regions of Republican Subordination.
- 1961: Name of capital changed back to Dushanbe.
- 1991-02: Name of capital of Leninobod changed from Leninabad to Khujand.
- 1993: Kulob and Qurghonteppa regions merged to form Khatlon. Before the change, the capitals had the same names as the
regions. The old Russian names were Kulyab and Kurgan-Tyube.
- 2000-08: Leninobod oblast renamed Sogd. Before this change, its ISO code was
TJ-LN. The name Sogd evidently
comes from that of an ancient region of central Asia, called Sogdiana by English-speaking scholars. Its capital in the Middle
Ages was Samarkand, which is now in Uzbekistan.
