ISO 3166-2:IT is the entry for Italy in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1.
Currently for Italy, ISO 3166-2 codes are defined for two levels of subdivisions:
Each code consists of two parts, separated by a hyphen. The first part is IT, the ISO 3166-1 alpha-2 code of Italy. The second part is either of the following:
- two digits: regions
- two letters: provinces
For the regions, the first digit indicates the geographical region where the subdivision is in:
- 2, 3, 4: Northern Italy
- 5: Central Italy (excluding Lazio)
- 6, 7: Southern Italy (including Lazio)
- 8: Insular Italy
For provinces, the two-letter part is an abbreviation of the province name, such as 'PG' for Perugia, although, as an exception, the code for Medio Campidano (IT-VS) is based on its two capitals, Villacidro and Sanluri.
Vehicle registration plates
In 1994, a new universal notation was introduced, dropping the province code entirely. This proved to be unpopular, and the two-letter code (or "ROMA") has been allowed to be added to a new, EU-style, blue border of the plates since 1999.
Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).
