ISO3166-2 codes for Italy cover 103 provinces. Each province has a 2-letter code, that is also used for car signs. Together with the ISO 3166-1 code IT for Italy they form the ISO 3166-2 codes. The purpose of this family of standards is to establish a worldwide series of short abbreviations for places, for use on package labels, containers and such. Anywhere where a short alphanumeric code can serve to clearly indicate a location in a more convenient and less ambiguous form than the full place name. US readers may wish to consider them as the equivalent of worldwide zip or postal codes. Within the Wikipedia, the codes from the country pages link to the pages for the locations they identify.
Note: FC which can be found on websites does not exist. This stands for Forli-Cesena. But the name of the province is Forli and results in the code FO.
