Italian Postcodes (zip codes) for all localities

Thousands of Italian localities, though not being a comune, have their own Zip or postal code ("CAP" in Italian); the alphabetical list here provided gives the three basic details necessary to write a correct mailing address in the format as they must appear on normalized addresses.

Italian Postcodes: Normalized Format

address format The last address line must show: the C.A.P (Codice Avviamento Postale, five digits), the locality in Italy, the two letters of the Italian province (which must NOT be included in brackets). There must not be any hyphens, underlinings, commas or other unnecessary punctuation.
For completeness of information, the postal address is followed by more details on the locality [between square brackets, separated by commas, details that must NOT be included in the mailing address] and exactly by: the Italian comune (only in case the locality is not a comune itself), the Italian province with a link to the page of that province, and the region.
Smaller cities have just one postcode and are included in the alphabetical list. For bigger cities it is necessary to find the street address in the alphabetical list for each city.
