Postal codes by place

The 60 places in Italy with the most postal codes recorded, listed alphabetically. Larger towns link to their own page.

Watch the leading zero

Some Italy postal codes begin with a zero, such as 00010. Spreadsheets and some web forms silently drop it, turning 00010 into 10 — which is either a different place or not a valid code at all. Format the column as text before pasting codes into a spreadsheet.

Look up a specific address

For the code covering one particular street or building, Italy's postal service publishes an official finder: www.poste.it/cerca/index.html#/risultati-cerca-cap. It is authoritative and kept current, which third-party copies often are not.
