What is the CAP?

The CAP (Codice di Avviamento Postale) is the 5-digit numeric code that identifies the postal delivery zone of every Italian locality. Introduced in 1967, it is the Italian equivalent of the US ZIP code and the German Postleitzahl.

The first two digits identify the province, the following ones the area and delivery zone. Large cities such as Rome, Milan and Naples use dozens of different CAPs, one per district, while most municipalities have a single one.

Italy currently has 4011 distinct CAPs serving 7896 municipalities. With this tool you can find the municipality behind a postal code, the CAP of a municipality, or browse the list of CAPs by region and province.

Frequently asked questions about Italian postal codes

What is the CAP?

The CAP is the Italian postal code: a 5-digit number identifying the postal delivery zone of each Italian municipality or district. It is used to sort and deliver mail correctly.

How do I find the postal code of a municipality?

Type the municipality name in the reverse lookup on this page to get its CAP instantly. Alternatively, every municipality page on DatiItalia lists the CAP alongside demographic data.

How many postal codes exist in Italy?

Italy has 4011 distinct CAPs across 7896 municipalities. The number can vary slightly over time with postal reorganizations and municipal mergers.

Why do some cities have more than one postal code?

Larger cities are split into multiple delivery zones: Rome has dozens (00118–00199), as do Milan and Naples. When shipping to these cities, use the street-specific CAP rather than the generic one.

Is the CAP the same as the ISTAT or cadastral code?

No: they are three different codes. The CAP is for mail, the ISTAT code identifies the municipality in official statistics, and the cadastral code is used for tax purposes, e.g. in the Italian fiscal code. DatiItalia lists all of them on each municipality page.
