Italian Address Format: How to Write an Italian Address Correctly

What is the correct Italian address format? An Italian address is written recipient-first, with the house number after the street name and the postal code (CAP) placed before the city on the last line, followed by the two-letter province abbreviation in parentheses — for example: Marco Bianchi / Via Roma 24 / 20121 Milano (MI). If you are sending from the United States, add ITALY in English capitals as the final line so USPS and UPS route the parcel to the right country.

What Is the Correct Format for an Italian Address?

A correctly formatted Italian address is stacked in four lines, working from the individual up to the postal district. Poste Italiane’s official address-composition standard gives this canonical structure:

• Recipient’s name (and title, or company/department name for business mail)
• Any building/floor detail — scala (staircase) and interno (apartment/unit), when the building has more than one entrance or unit
• Street type + street name, followed by the house number — e.g. Via Roma 24 (the number always comes after the name)
• CAP (5-digit postal code) + city + province abbreviation in parentheses, all on one line, in that order

Poste Italiane recommends writing the whole block in capital letters for optical-reader legibility, and its guidance is explicit that the house number sits after the street name, never before it — the reverse of the US convention. When a US shipper prepares a label through a platform like ParcelPath’s Italy shipping page, that same order applies, with one addition covered below: the destination country on the final line.

What Are the Essential Components of an Italian Address?

Each line does a specific job in the delivery chain. The line most US senders get wrong is the last one — the CAP, city, and province all belong together, in that exact order, with the province in parentheses.

Line	What it is	Example	Required?
Recipient	Person or business receiving the item	Marco Bianchi	Yes
Interno / Scala	Apartment (interno) and staircase (scala) for multi-unit buildings	Scala B, Interno 7	Only if needed
Street line	Street type + name, then house number	Via Roma 24	Yes
CAP	5-digit Codice di Avviamento Postale, placed before the city	20121	Yes
City	Comune (municipality) name	Milano	Yes
Province	2-letter province abbreviation, in parentheses after the city	(MI)	Yes
Country	Destination country for international mail	ITALY	Yes (from abroad)

The single most common surprise for people used to US addressing is that the CAP comes before the city, not after it, and that the city is followed by a parenthetical province code rather than a state name. Together, 20121 Milano (MI) forms one inseparable line — Poste Italiane’s own worked examples never split the CAP, city, and province across two lines.

How Does the Italian Postal Code (CAP) System Work?

The CAP is the part that does the heavy lifting, and it has a strict internal grammar. Every CAP is exactly five digits, and Wikipedia’s breakdown of the Codice di Avviamento Postale system explains what each digit does:

• Digits 1–2: the administrative province — every one of Italy’s roughly 110 provinces has its own 2-digit prefix (e.g. all Firenze CAPs begin with 50).
• Digit 3: flags whether the town is the province’s capital — odd (usually 1 or 9) means yes, even (usually 0 or 8) means no.
• Digits 4–5: pin down the specific town or village, or, in large cities such as Rome, Milan, Naples, and Venice, a specific urban postal district within that city.

Position is the part that trips up US senders: the CAP goes before the city, on the same line — not after it, and never on its own line. Immediately following the city, Italian convention adds the two-letter province abbreviation in parentheses, e.g. 56123 Pisa (PI) or 04100 Latina (LT). This province-in-parentheses convention is the single most distinctive marker that an address has been formatted the Italian way rather than simply translated from an English template.

Two more grammar rules matter for the street line itself. First, the house number always follows the street name — Via Roma 24, not “24 Via Roma.” Second, the street-type word is part of the name, not a throwaway label: Via (street), Viale (avenue/boulevard), and Piazza (square) are the three most common prefixes, alongside Corso (main thoroughfare) and Vicolo (alley); dropping or abbreviating them can cause a sorting delay because Italian street databases index on the full prefixed name.

How Do You Address an Italian Parcel From the United States?

Shipping into Italy from the US adds exactly one rule to everything above: the last line of the address must be the destination country, written in English capitals — ITALY. USPS and UPS sort outbound international parcels by that country line first, before the CAP is ever read, so omitting it is the fastest way to have a package held or returned.

Practical points for US-origin Italian shipments:

• Keep the CAP-city-province line intact and on its own row, immediately above the country line — e.g. 50123 Firenze (FI) then ITALY beneath it.
• Use Latin characters throughout. Italian addresses use the standard Latin alphabet with occasional accented vowels (à, è, ì, ò, ù) — keep them if you can, but a dropped accent rarely causes a misroute since the CAP carries the routing weight.
• Include a working phone number and email in the label’s contact fields — Italian customs and last-mile couriers use them for duty contact and delivery notifications.
• Both USPS and UPS reach Italian addresses, and ParcelPath issues discounted USPS and UPS labels for the Italy lane — the Italy destination guide covers current transit windows and customs paperwork. ParcelPath ships via USPS and UPS only; Poste Italiane is Italy’s own national postal operator and handles last-mile delivery inside the country, not the outbound US leg.

What Are the Most Common Italian Address Mistakes to Avoid?

Almost every failed or delayed Italian delivery traces back to one of a short list of formatting errors:

• Putting the CAP after the city instead of before it. “Milano 20121” reads backward to an Italian sorting system — the correct order is 20121 Milano.
• Omitting the province abbreviation in parentheses. A CAP and city alone are usually enough for delivery, but leaving off (MI), (RM), or the relevant two-letter code breaks the format Poste Italiane’s own guidance specifies.
• Writing the house number before the street name. The US habit of “24 Via Roma” should be flipped to “Via Roma 24.”
• Dropping the “int.” (interno) or “scala” notation on apartment buildings. Without it, a parcel can reach the right building but never the right unit.
• Abbreviating or dropping the street-type prefix. “Roma 24” instead of “Via Roma 24” strips information the Italian postal database indexes on.
• Forgetting “ITALY” on mail sent from abroad. Without the country line, a US carrier can’t route the parcel internationally.

How Do You Handle Interno, Scala, and Italy’s Micro-States?

A few Italy-specific cases trip up international senders:

• Interno (apartment/unit) is written as “Int.” or “Interno” followed by the unit number or letter, e.g. Interno 7. It identifies which specific unit within a building the item is for, similar to a US apartment number.
• Scala (staircase) applies to larger residential buildings with more than one entrance/stairwell, each lettered — e.g. Scala B. When both apply, the convention is Scala B, Interno 7, placed on its own line above the street line or appended after the house number.
• San Marino is a fully independent country that sits entirely inside Italy’s borders, but its mail is integrated into the Italian CAP range (codes 47890–47899). Address mail to San Marino with its own postcode and the line “REPUBBLICA DI SAN MARINO” — not “ITALY” — as the country line.
• Vatican City is also a separate sovereign state with its own CAP, 00120, and its own postal administration, even though it sits inside Rome. Mail to the Vatican should read “VATICAN CITY” (or “CITTÀ DEL VATICANO”) as the country line, not “ITALY.”
• Sicily and Sardinia use the same CAP and province-abbreviation system as mainland Italy — no special handling is needed beyond using the correct island province code (e.g. (PA) for Palermo, (CA) for Cagliari).

Frequently Asked Questions

Does the CAP go before or after the city in an Italian address?

Before. The correct order is CAP, then city, then the province abbreviation in parentheses — for example 20121 Milano (MI). This is the reverse of the US convention of city first, and it is the single most common formatting mistake American senders make on Italian mail.

Do I need to include the province abbreviation?

Yes. Poste Italiane’s official address-composition standard places the two-letter province code in parentheses immediately after the city on the same line as the CAP. Leaving it off doesn’t always block delivery since the CAP alone routes to the right sorting office, but including it matches the format Italian systems expect and avoids ambiguity between comuni that share a name in different provinces.

Where does the house number go relative to the street name?

After the street name, not before it. Write “Via Roma 24,” not “24 Via Roma.” The street-type word — Via, Viale, Piazza, Corso — always stays attached to the street name and should never be dropped or abbreviated.

Do I add “ITALY” when shipping from the US?

Yes — always, as the last line in English capitals. USPS and UPS sort outbound parcels by the destination country first. Without “ITALY,” the parcel can be held domestically or returned before it ever leaves the US. The exception is San Marino, which should read “REPUBBLICA DI SAN MARINO,” and Vatican City, which should read “VATICAN CITY.”

What do “interno” and “scala” mean on an Italian address?

Interno (often abbreviated “Int.”) identifies the specific apartment or unit within a building, similar to a US apartment number. Scala identifies which lettered staircase or entrance to use in a larger multi-entrance building. Both are added after the street line when the building has multiple units or entrances, e.g. “Via Roma 24, Scala B, Interno 7.”
