Provinces of Italy
Updates: 
The original ISO 3166-2 Newsletter I-8 was published on 2007-04-17. It had ISO codes for the new provinces of Italy. However, two of
them didn't match the provincial sigle. When this was brought to the attention of the maintenance agency, they revised the codes.
A corrected version of the newsletter was issued, bearing the same date; I received notification of it on 2007-05-10. (The reason I go
into all this detail is that some of my readers may have saved the original newsletter, and may now be wondering why their ISO codes don't
match mine.) The updated codes are shown in the table below.
Thanks to Richard Forstall for providing me with demonyms for two new provinces. Thanks to Gabriele Marcoccia for providing me with
demonyms for four regions which I had not listed.
The NUTS code scheme was revised in 2003. All codes for Italy that were listed on this page have changed. The NUTS-1 level areas, known
as gruppi di regioni (groups of regions) were consolidated from eleven groups into five. The new codes are shown.
Mario Pezza writes that new provinces appear on maps as of the date of the law creating them, but only become active when their first
provincial council is elected. Therefore, the provinces of Barletta-Andria-Trani, Fermo, and Monza e Brianza are defined as of
2004-06-11, the date the laws were passed. The projected dates when they will become active are 2008 (Barletta), 2009-01-01 (Fermo), and
2009 (Monza). Wikipedia says that Monza will be the sole capital of Monza e Brianza. I have added these provinces to the table in
anticipation.
International standard ISO 3166-2 was published on December 15, 1998. It superseded ISO/DIS 3166-2 (draft international standard). For
Italy, the draft standard showed 20 regions and ignored the provinces. The final standard shows the same 20 regions with the same codes,
but no longer as primary divisions of Italy. Instead, the 103 provinces are shown as the primary subdivisions.

Italy struggled its way to national unification in the 19th century, except for some Italian-speaking borderlands called Italia
irredenta (unredeemed Italy). In World War I, Italy chose the winning side. In reward, it achieved its main territorial ambitions: the
incorporation of the South Tyrol and the area around Trieste. After World War II, as a defeated Axis power, it lost part of Trieste, and
all of its colonies.

- Province: Names are given in their common English form, where that differs from the Italian.
- HASC: Hierarchical administrative subdivision codes.
- ISO: Codes from ISO 3166-2 (see note below).
- CAP: Codici di Avviamento Postale (postal codes). Italy has a system of five-digit postal codes.
The first two
digits are constant within each province. (In a few cases, two or more provinces use the same first two digits.)
- NUTS: Nomenclature of Territorial Units for Statistics, a European standard. The first four
characters of
the NUTS code for each province are the NUTS code for the region to which the province belongs. (If the fourth character is a
0, it is truncated.)
- Population: 2001-10-21 census.
- Reg: Region to which the province belongs (see list below).
- Capital: Capitals have the same names as provinces. When a province name mentions more
than one city, they
are co-capitals. Exceptions: The capital of Medio Campidano is Sanluri. The capitals of Ogliastra are Lanusei and Tortolě. The
capital of Monza e Brianza is Monza.
- Adjective: Masculine plural adjective for inhabitants of the provincial capital, or the province as
a whole.
|
Note: ISO codes have not yet been assigned for the three newest provinces, Barletta-Andria-Trani, Fermo, and Monza e Brianza. I have
listed the sigle automobilistiche instead. Sigle automobilistiche, or sigle de provenienza (vehicle codes, provenance codes) are
used in Italy on license plates, maps, forms, etc. In the past, the ISO codes had always matched the sigle. However, in 2007, ISO
pulled a switch. When assigning codes to the new Sardinian provinces created in 2001 and activated in 2005, ISO deviated from the sigle
in two cases: Medio Campidano (whose sigla is VS) and Olbia-Tempio (OT).
License plates from Rome province, however, have the full name, ROMA. About 2000, when the province names changed, the
sigle for Forlě-Cesena changed from FO to FC, and for Pesaro e Urbino from PS to PU.
For more historical background, see the targhe
page.
Further subdivisions:
See the Communes of Italy page.
Above the province level, Italy is subdivided into twenty regione (pl. regioni: region). Officially, these are autonomous regions with
ordinary statute, except for five autonomous regions with special statute (FV, SC, SD, TT, VD). Both regions and provinces are frequently
used in statistical lists, and to locate places. Regions were known as compartimenti (departments) until World War II. The provinces are
further subdivided into comuni (communes). There are also some groups of communes that form an intermediate administrative level, the
circondari (districts). When new provinces are formed, sometimes the area of the province is a former circondaro.
