How to Call Italy from the US
Dial 011 + 39 + Italian number — keeping the leading 0 for landlines. Step-by-step dialing, area codes, time zones, costs, and the leading-0 trap explained.
Key facts (as of June 2026): To call Italy from the US, dial 011 + 39 + the area code and local number (Italy keeps its leading 0). 011 is the US international exit code and 39 is Italy’s country code. From a US mobile, press and hold 0 to enter + and dial +39 instead of 011.
To call Italy from the US, dial 011 + 39 + Italian number — keeping the leading 0 for landlines.
Rome example: 011 39 06 1234 5678 (note: 06 includes the 0 — do not strip it).
Milan example: 011 39 02 9876 5432 (02 keeps the 0).
Italian mobile: 011 39 347 123 4567 (no leading 0 — mobiles start with 3, not 0).
This is the most common point of confusion: Italy is one of the only countries in the world where the trunk prefix 0 is kept when dialing internationally. Most guides — and most callers — get this wrong.
How to dial Italy from the US
Follow these five steps from any US landline or mobile:
- Dial 011 — the US international exit code. All international calls from the US start here. On a US mobile, long-press 0 to enter + as a shortcut.
- Dial 39 — Italy’s country code (ITU-assigned).
- Dial the full Italian area code, including the leading 0. Rome is 06. Milan is 02. Naples is 081. Do not strip the 0 — see the leading-0 section below.
- Dial the local subscriber number exactly as written.
- Press call / send.
Full pattern: 011 39 <area-code-with-0> <local-number>
If you already have the number in international format — for example +39 06 1234 5678 from an Italian business card — replace + with 011 on a US landline, or dial it as-is with + from a US mobile.
Italian area codes by city
Italian landline numbers are structured as: area code (including leading 0) + local subscriber number.
Large cities use 2–3 digit area codes; smaller towns use 4-digit codes. The leading 0 is part of the code and is always dialed from the US.
| City | Area code | Dial from US |
|---|---|---|
| Rome | 06 | 011 39 06 XXXXXXXX |
| Milan | 02 | 011 39 02 XXXXXXXX |
| Naples | 081 | 011 39 081 XXXXXXX |
| Turin | 011 | 011 39 011 XXXXXXX |
| Florence | 055 | 011 39 055 XXXXXXX |
| Bologna | 051 | 011 39 051 XXXXXXX |
| Venice | 041 | 011 39 041 XXXXXXX |
| Genoa | 010 | 011 39 010 XXXXXXX |
| Palermo | 091 | 011 39 091 XXXXXXX |
| Catania | 095 | 011 39 095 XXXXXXX |
Turin trap: Turin’s area code is 011 — identical to the US exit code. When dialing Turin from the US you dial 011 39 011 XXX XXXX. The repeated 011 looks strange but is correct: the first 011 is the US exit code, the second is Turin’s area code.
Italian mobile numbers use prefixes in the 3xx range (310–399) and are 10 digits total. There is no leading 0. Example: 347 123 4567 → dial 011 39 347 123 4567.
How Italian numbering works
Italy’s telephone numbering plan is managed by AGCOM — Autorità per le Garanzie nelle Comunicazioni, the national communications regulator established in 1997.
In 1998 AGCOM mandated that all landlines include the area code for every call, even local ones. This was a deliberate structural decision: the trunk prefix 0 became part of the area code itself rather than a domestic-only routing digit.
The result: unlike France, the UK, Germany, or the US, Italy never adopted the rule of dropping the 0 when calling internationally. ITU guidelines allow member countries to define their own trunk prefix treatment, and Italy chose retention.
This is documented in Italy’s national numbering plan submitted to the ITU and on the Wikipedia article for Telephone numbers in Italy: “the leading 0 of landline numbers has to be included also when calling from abroad.”
If you encounter an Italian number written as +39 (0)6 1234 5678, the parentheses around the 0 are a convention borrowed from countries that do drop the trunk prefix. In Italy’s case, dial both: +39 06 1234 5678.
Time zones — CET / CEST
Italy runs on Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) April–October.
Italian daylight saving switches on the last Sunday of March (clocks forward) and the last Sunday of October (clocks back). US daylight saving switches on the second Sunday of March and first Sunday of November.
During the brief overlap periods in late March and late October, the offset shifts by 1 hour from the values below.
| US time zone | Standard offset (winter) | DST offset (summer) |
|---|---|---|
| Eastern (ET) | Italy +6h | Italy +6h |
| Central (CT) | Italy +7h | Italy +7h |
| Mountain (MT) | Italy +8h | Italy +8h |
| Pacific (PT) | Italy +9h | Italy +9h |
Italian office hours: 9 AM–1 PM and 3 PM–7 PM CET. Best US-to-Italy call windows:
- New York: 3 AM–7 AM ET or 9 AM–1 PM ET (afternoon window)
- Chicago: 2 AM–6 AM CT or 8 AM–12 PM CT
- Los Angeles: midnight–4 AM PT or 6 AM–10 AM PT
For regular business calls to Italy, a 9 AM–1 PM ET call window reliably lands during Italian afternoon hours (3 PM–7 PM CET) — the most productive overlap.
US to Italy calling costs
Cost depends on your method:
Carrier per-minute rates (no plan): $0.05–$0.25/min to Italian landlines; $0.10–$0.35/min to Italian mobiles. AT&T, Verizon, and T-Mobile publish current Italy rates in their international calling pages.
Carrier international add-on packages: typically $5–$15/month for discounted rates. Rates drop to roughly $0.05–$0.15/min to Italy.
VoIP per-minute rates: lowest cost path. Providers including DialPhone business phone charge well under $0.05/min to Italy with no monthly minimum. For teams calling Italy weekly — sales, procurement, partner management — VoIP saves meaningfully over carrier add-ons.
Free options: WhatsApp, FaceTime Audio, and Signal work between devices over Wi-Fi/data, but require the Italian contact to have the same app. Not reliable for cold outreach or business-to-business calls.
See DialPhone pricing for current Italy per-minute rates by plan.
Calling Italian mobile vs. landline — the leading-0 trap
This is the single most error-prone element of calling Italy from the US. Here is the rule in one table:
| Number type | Starts with | Leading 0? | Example dial string |
|---|---|---|---|
| Landline | 0 (area code) | Keep the 0 | 011 39 06 1234 5678 |
| Mobile | 3 (mobile prefix) | No 0 | 011 39 347 123 4567 |
Why callers get this wrong: every guide for every other major country (UK, France, Germany, Australia) tells you to drop the leading 0 internationally. Italy is the exception. If you or your team regularly calls both Italy and other European countries, explicitly save Italian numbers in your contacts with the 0 included — for example +39 06 1234 5678 — so the number dials correctly regardless of where you are calling from.
How to tell a mobile from a landline: Italian mobiles always begin with 3 in their national format. Landlines always begin with 0. There is no ambiguity. If the first digit after +39 is 3, it is a mobile — no leading 0 to worry about.
STIR/SHAKEN and Italy: US-originating VoIP calls to Italy pass through international gateways that may lack full STIR/SHAKEN attestation handshakes. Italian recipients using newer mobile carriers may see calls marked as unverified. Using a verified VoIP platform with a signed caller ID — such as DialPhone, which implements STIR/SHAKEN on outbound calls — significantly reduces spam-flag rates on Italy-bound calls and improves answer rates for business outreach.
SMS to Italy and US-Italy business use cases
SMS to Italian mobiles (numbers starting with 3) works from any US number. Use +39 3XX XXX XXXX in any messaging app. Standard carrier SMS rates to Italy are $0.05–$0.25 per message without a plan.
US-Italy business verticals where reliable calling matters most:
Italy is a major US trade partner across several industries where phone communication remains critical:
- Fashion and luxury goods: Milan is the global hub. US importers, buyers, and brand representatives call Milan-area (02) numbers regularly.
- Automotive: Ferrari, Lamborghini, Maserati, Fiat — all headquartered in the Emilia-Romagna region (Bologna 051, nearby Modena). US dealer and distribution calls are frequent.
- Food and wine: Italy is one of the largest sources of US food and wine imports. Importers and distributors coordinate with producers in Tuscany (055), Veneto (041 — Venice/Verona), and Sicily (091/095).
- Industrial equipment and manufacturing: Northern Italy (Turin 011, Genoa 010, Milan 02) hosts major machinery exporters with active US sales teams.
For companies with ongoing Italy call volume, an Italian virtual number (IT DID) lets US-based teams present an Italian caller ID — reducing hang-up rates and improving answer rates. Italian contacts see a local number rather than a flagged international call. Pair with DialPhone AI Receptionist to handle inbound Italian calls 24/7.

FAQ
Calling Italy FAQ
What is Italy's country code?
Italy's country code is +39, assigned by the International Telecommunication Union (ITU). From a US landline you prefix it with the exit code 011, making the full sequence 011 39. From a US mobile that supports E.164 dialing, you can substitute + for 011 and dial +39 directly.
Do I keep or drop the leading 0 when calling Italy from the US?
Keep it — for landlines. Italy is one of the few countries in the world where the trunk prefix 0 is retained even when dialing internationally.
If the Italian number is 06 1234 5678 (Rome), you dial 011 39 06 1234 5678 — the 06 stays intact. This rule was codified by AGCOM (Italy's telecom regulator) in 1998 and catches many callers off guard because almost every other country drops its trunk prefix internationally.
Why does Italy keep the leading 0 internationally?
Italy integrated the trunk prefix 0 into its numbering plan as a structural part of each area code rather than a pure domestic-only prefix. AGCOM — Autorità per le Garanzie nelle Comunicazioni — formalized this in the 1998 national numbering plan overhaul.
The practical effect: when you see +39 (0)6 in an Italian business listing, both the 39 and the 06 are dialed. The parentheses around the 0 are a formatting convention, not an omission instruction.
How do I call Rome from the US?
Rome's area code is 06. Dial 011 39 06 followed by the local subscriber number (typically 7–8 digits). Example: 011 39 06 1234 5678.
Note that 06 includes the mandatory leading 0. Do not strip it — dialing 011 39 6 1234 5678 will fail or reach a wrong number.
Do Italian mobile numbers have a leading 0?
No. Italian mobile numbers begin with 3 (prefixes 310–399) and have no leading 0. To call an Italian mobile from the US, dial 011 39 3XX XXX XXXX — no 0 before the 3.
This is the key distinction: landlines start with 0 (keep it); mobiles start with 3 (no 0 to keep). Getting this wrong is the second-most-common mistake after forgetting the exit code.
What time zone is Italy in?
Italy observes Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) during daylight saving. Relative to the US:
• New York (ET): Italy is 6 hours ahead in winter, 6 hours ahead in summer (clocks change on different dates — confirm around the transition periods in late March and late October). • Chicago (CT): 7 hours ahead. • Denver (MT): 8 hours ahead. • Los Angeles (PT): 9 hours ahead.
Italian business hours are typically 9 AM–1 PM and 3 PM–7 PM CET. A New York caller has a workable overlap from 9 AM–1 PM ET (3 PM–7 PM Rome).
How much does it cost to call Italy from the US?
Without an international plan, major US carriers charge roughly $0.05–$0.25 per minute to Italian landlines and $0.10–$0.35 per minute to Italian mobiles.
Carrier international add-on packages (typically $5–$15/month) reduce rates significantly. VoIP providers offer the lowest rates — often under $0.05/minute to Italy — with no per-month minimum for low-volume callers. See DialPhone pricing for current Italy per-minute rates.
Can I text Italy from the US?
Yes. SMS to Italy works from any US number to an Italian mobile (numbers starting with 3). The format mirrors calling: use +39 3XX XXX XXXX in your messaging app. Carrier SMS rates to Italy are typically $0.05–$0.25 per message without a plan.
For business SMS — appointment reminders, order confirmations, B2B notifications — a VoIP platform with Italy SMS termination and a local Italian virtual number improves deliverability and reply rates.
