To reach a Italy number from the United States, dial these three parts in order.
011 39 312 345 6789
From any mobile, anywhere in the world, you can dial +39 312 345 6789 instead. Press and hold 0 to type the +, and the phone picks the right access code for wherever you are.
Italy numbers carry no leading trunk digit, so there is nothing to strip. 312 345 6789 is dialed exactly as written, with +39 in front. Removing a digit here is what makes the call fail.
A typical Italy mobile number is 10 digits after +39. If a call does not connect, count the digits first.
Only the first part changes. Your access code replaces the 011, then 39 and the number stay exactly the same.
A ~ means wait for the second dial tone before dialing the rest. It is not a digit you press.
Calls to Italy are $0.07 a minute, billed by the minute. There is no connection fee, no monthly plan, and no minimum spend. You add prepaid credit from $5, and it never expires.
Only for the time you actually talk.

The heaviest inbound stream into Italy comes from the United States, home to roughly 17.8 million people of Italian descent and about 5.5 million Italian immigrants who arrived between 1820 and 2004, most from the Mezzogiorno (Campania, Calabria, Sicily, Puglia) - Library of Congress. The densest hubs are the New York metro area (over 2.3 million Italian Americans in New York State) and New Jersey (about 1.4 million), where towns like Fairfield, NJ are more than half Italian by ancestry - worldpopulationreview. These callers ring 06 (Rome), 081 (Naples), and small Sicilian and Calabrian 0-prefixed landlines to reach elderly relatives who still keep a fixed line, plus 3xx mobiles for cousins and grandchildren.
Beyond the US, big inbound corridors run from Argentina and Brazil (enormous Italo-descendant populations from the same great migration), Germany, Switzerland, Belgium, and the UK (postwar guest-worker diasporas), plus Australia and Canada. A separate, growing stream comes from newer immigrant communities living inside Italy who are called by relatives back in , , , , and . Business calls flow inbound too: fashion and design buyers dialing , food and wine importers reaching producers in or , and tourists confirming reservations in or .
Dial your international access code, then Italy's country code 39 (from a phone keypad, hold 0 to get + and dial +39; from the US you can also dial 011 then 39).
Enter the full national number EXACTLY as written, INCLUDING the leading 0 for landlines. Do NOT drop the trunk 0: Italy is the exception to the usual rule.
For a landline, the 0 and area code are part of the number: +39 06 4520 1234 for Rome, +39 02 8901 2345 for Milan.
For a mobile, dial +39 then the full 3xx number: +39 347 123 4567 (mobiles are 10 digits and never carry a leading 0).
With browser calling, just pick Italy and type the local number as the Italian owner wrote it; the +39 is added for you.
The one rule that catches everyone: keep the leading 0 on landlines when calling from abroad. Since 1998 Italy requires the trunk 0 even on international calls, unlike almost every other country - Wikipedia. Mobiles start with 3 and have no leading 0, so nothing to strip there. Expect variable length: landlines run 6 to 11 digits total (a two-digit 06/02 code leaves a longer body; small-town four-digit codes leave a shorter one), while mobiles are almost always 10 digits - . Avoid dialing toll-free lines from outside Italy (they often reject foreign callers) and the premium ranges. Italy's own outbound access code is (for example to reach the US), which is not used when calling into Italy - .
Italy's single most confusing feature for anyone dialing in is the mandatory trunk 0. Since 1998 the leading 0 of a landline must be included even when calling from abroad, a reform that scrapped the old system where you dropped the 0 internationally and forced the full number for local calls too - Wikipedia. Before that reform Romans could dial a neighbor with just the 7-digit subscriber number; now everyone dials 06 first even within the city. The upshot: US callers who apply the usual "drop the 0" rule they learned for the UK or France will fail to connect to an Italian landline. The 0 is not a trunk prefix you remove, it is part of the number.
Number portability, live since 2002, has quietly broken the old habit of reading the operator from the prefix - Wikipedia. A 3xx block was originally assigned to one carrier (roughly 33x to TIM, 34x to Vodafone, 32x/38x to WindTre, 350/351 to Iliad), but a number can now sit on any network, so the prefix tells you where a mobile was born, not who runs it today - Telecompaper. Italians who want to know the current operator dial followed by the mobile number for a recorded answer.
An Italian number has two shapes. A landline begins with 0 and packs the area code and subscriber number into one string of 6 to 11 digits, for example 06 4520 1234 in Rome or 02 8901 2345 in Milan - en.wikipedia.org. A mobile begins with 3 and is almost always 10 digits, written as a 3xx prefix plus a 7-digit body, like 347 123 4567 - countrycode.com. The country code is 39, so in full form a Rome office is +39 06 4520 1234 and a mobile is +39 347 123 4567.
The grouping is loose in practice: Italians write 06.45201234, 06 452 01234, or 0645201234 interchangeably, and mobiles as 347 1234567 or 3471234567. What never changes is the leading digit: 0 means fixed, 3 means mobile. If you see a leading 0 you keep it; if you see a leading 3 it is a cellphone, and both landline and mobile keep every digit you see when dialed from abroad.
Watch for the special ranges so you don't mistake them for a person: and are toll-free numero verde lines, and the family (, , , ) is premium-rate, priced high on purpose - . The old and premium prefixes were retired for value-added services at the end of , and the space is now reserved for services like emergencies - .
Italy is the country where the biggest cities got the shortest codes. Only Rome (06) and Milan (02) hold two-digit codes, a legacy of their size and importance - List of dialling codes in Italy. Everything else is three digits starting with 0: Naples 081, Turin 011, Genoa 010, Bologna 051, Florence 055, Venice 041, Bari 080, Palermo 091, Catania 095, Verona 045, Cagliari 070, Trieste 040, and Brescia 030 - en.wikipedia.org. Small towns push to four-digit codes, which is why landline length varies so much: the shorter the code, the longer the subscriber body, and vice versa.
Because the area code is fused into the number and always dialed, an Italian landline still betrays geography in a way many countries' numbers no longer do. A 055 number is genuinely in the Florence province, an 081 number is Naples and its surroundings. That makes area codes a real signal for the diaspora: a caller in Brooklyn dialing +39 081 ... knows the phone rings in Campania. Mobiles carry no such geography, since 3xx is nationwide.
One gotcha for reading old paperwork: numbers written before the late 1990s sometimes appear without the 0 or with the 0 in parentheses, reflecting the pre-1998 convention. Today the 0 is never optional. If a business card shows a bare 7-digit Rome number, prepend and you have the modern form.
Most personal calls to Italy land on 3xx mobiles, which are the default line for anyone under roughly 60 and increasingly for everyone. WindTre, TIM, Vodafone, and Iliad split the market fairly evenly, with WindTre and TIM leading and Iliad (launched 2018 on 350/351) taking around 15% - Telecompaper. Because of portability the network behind a given number is unpredictable, but that is invisible to you as a caller: you dial the same 10 digits regardless.
Elderly relatives are the classic reason the landline still matters. Many nonni in southern villages keep a fixed 0-prefixed line as their only reliable phone, so diaspora callers often keep two numbers on file: the grandparent's landline and a grandchild's mobile who can hand over the phone. When you can only reach a landline, remember Italian household phones are frequently unanswered during the long midday break and after dinner is when families are together.
Business and government lines are their own world. Company switchboards sit on the city 06/02/081 codes; larger firms publish a numero verde 800 that only works inside Italy. Public bodies like INPS (social security), the Agenzia delle Entrate (tax), and utilities route through Italian-language IVR menus and can be slow to reach a human, so if a relative gave you a direct extension, dial it. For emergencies inside Italy the single number is 112, alongside the historic 113 (police), 115 (fire), and 118 (medical) - Wikipedia.
The midday pause is real and worth planning around. In many households and small businesses, especially in the South, the hours from roughly 1pm to 4pm are for lunch and rest, and a call then can go unanswered or be unwelcome. The reliable personal windows are late morning and the evening after dinner, which in Italy runs late: 8pm to 10pm local is prime family time and perfect for a call from a US afternoon.
Italians answer the phone with "Pronto" ("ready"), not their name, and calls to older relatives tend to be longer and more ceremonial than a quick American check-in, so budget more than a couple of minutes. On mobiles, a common frugal habit called "fare uno squillo" (letting it ring once) is used as a free signal to call back, a leftover from expensive prepaid days that still shapes phone manners.
One timing trap specific to Italy: it observes European daylight saving, shifting to CEST (UTC+2) on the last Sunday of March and back to CET (UTC+1) on the last Sunday of October - timeanddate.com. US and EU DST changeovers are a week or two apart in spring and fall, so for a couple of weeks each year the usual 6-hour US-Eastern gap briefly becomes 5 or 7. If a call that always worked suddenly lands at the wrong hour in March or late October, the clocks are the reason, not the number.
Keep it. Italy is the well-known exception: since 1998 the leading 0 is required even from abroad, so a Rome number dials as +39 06 ..., not +39 6 ... - Wikipedia. Only mobiles lack a leading 0, because they start with 3.
Look at the first digit. 3 means mobile (almost always 10 digits, like 347 123 4567); 0 means landline (6 to 11 digits, with the area code built in) - Wikipedia. There is no separate mobile country code; both use +39.
They are historical. Rome (06) and Milan (02) are the only two-digit codes in Italy, a legacy of their size; almost every other city uses a three-digit code starting with 0, like Naples 081 or Florence 055 - List of dialling codes in Italy. Smaller towns use four-digit codes.
Because of number portability, live since 2002, any 3xx number can move to any network - Wikipedia. The prefix only shows the original operator, not the current one. It makes no difference to you: you dial the same 10 digits either way.
Italian numero verde lines (800, 803) are typically restricted to callers inside Italy and reject foreign calls - numeridiassistenza.com. To reach the same company from abroad, dial its geographic switchboard on the city 06/02/081 code instead.
Not if your call presents a valid caller ID. The AGCOM filter (phased in August and November 2025) blocks foreign calls that spoof Italian landline or mobile numbers, not honest international calls - Euronews. Calling through a service that presents a clean, valid number is exactly what the rule is designed to let through.
Add a little credit and dial any Italy number right from your browser.
Start callingPeople inside Italy dial out using the international access code 00 before the destination country code (a call to a US number is 00 1 ..., a UK number is 00 44 ...) - Wikipedia: Telephone numbers in Italy. The + on a mobile keypad substitutes for that 00, which is why saved contacts almost always start with +. The most common outbound destinations mirror the diaspora in reverse: relatives in Germany, Switzerland, the UK, the US, Argentina, and Brazil, plus the home countries of Italy's own large migrant communities (Romania, Albania, Morocco, China, Ukraine).
A quirk worth flagging: Italians are so used to typing the full national number with its leading 0 for domestic calls that they sometimes leave that habit on when dialing abroad, or forget to strip the trunk 0 off a foreign number. Italy itself keeps its trunk 0 (see the dialing notes), but most other countries drop it after the country code, so an Italian calling a French or German landline must remove the foreign leading 0. Browser calling sidesteps the confusion: you pick the destination country and type the local number, and the tool assembles the rest.
Robocalls and spoofing are a national nuisance: over 75% of Italians report at least one unwanted call per week, and complaints to the Registro Pubblico delle Opposizioni (the public opt-out register) jumped 30% in 2023, past 200,000 reports - Mobile Ecosystem Forum. In response AGCOM (Resolution 106/25/CONS) rolled out a two-phase anti-spoofing filter: from 19 August 2025 networks block foreign calls faking an Italian landline caller ID, and from 19 November 2025 the block extended to foreign calls faking Italian mobile numbers, with real-time checks on number validity, operator assignment, and routing - Euronews. A side effect: a poorly configured international call that presents a malformed Italian-looking caller ID can now be dropped, so calling through a service that presents a clean, valid CLI matters more than it used to.
Two practical reachability notes. Toll-free 800 and 803 "numero verde" lines usually reject calls from outside Italy, so a bank or airline's free hotline often cannot be reached from the US at all; you need the geographic 06/02 switchboard instead. And official incoming and premium lines behave differently from ordinary numbers: the 89x premium ranges are billed at high rates, and Italian government, bank, and utility hotlines frequently route through IVR menus in Italian only, so reaching a human on a CAF, INPS, or bank line takes patience and, ideally, the direct extension.
