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:

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

The two-letter provincial codes were used in vehicle registration plates between 1905 and 1994 (except for Rome, whose vehicle code has always been ROMA instead of RM).

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.

Current codes

Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).

ISO 639-1 codes are used to represent subdivision names in the following administrative languages:
