The country code for Italy is +39. Dial that, then the Italian number with its leading zero kept in place, and the call will connect. If you learn only one thing from this article, learn that last part. Italy is one of the few countries in the world where the leading 0 of a landline area code stays on the number when you dial from abroad. Almost everyone gets this wrong the first time, including people who have been calling Italian relatives for decades.
I write a lot about international dialing because the small conventions matter. A wrong prefix, a stripped zero, a mis-set carrier plan, and you are listening to a dead tone wondering why your mother in Palermo did not pick up. This guide walks you through every piece of the Italian numbering plan, how to actually dial from the US and other countries, what the quirks are, and how to keep the call from costing you a Sunday afternoon in roaming fees.
The short version
To call an Italian number from anywhere outside Italy:
+39, then the full Italian number exactly as written, leading 0 included on landlines
To call an Italian landline from a US desk phone, dial 011 + 39 + 0 + area code + subscriber number. To call an Italian mobile, dial 011 + 39 + 3xx + the rest of the mobile number.
The 011 is the US exit code. In most of Europe, including when you are already in Italy and dialing another country, you use 00 instead. From a mobile phone anywhere, the + symbol replaces either one. So +39 06 1234 5678 works equally well whether you are in Chicago, Lagos, Melbourne, or Berlin.
Why +39 keeps the leading zero (and almost nobody else does)
The International Telecommunication Union assigned +39 to Italy decades ago. What makes Italy unusual is a 1998 numbering reform. Before that year, Italians dialing within the same district skipped the area code entirely. The change, promoted to the public with the slogan "Fissa il prefisso" (attach the prefix), made the full number including the leading 0 mandatory on every call, local or long distance. The side effect was that the leading 0 stopped being a trunk code that disappeared on international calls and became part of the number itself. Today the numbering plan is overseen by AGCOM, the Italian communications regulator.
So Rome's area code is 06, and the full international string is +39 06 followed by the subscriber number. Not +39 6. Compare this with France, Germany, and the UK, where you drop the leading 0 after the country code, or with Spain, which has no trunk 0 at all. Italy keeps it. If your call fails on the first try and you are sure the number is right, this is almost always the reason.
Mobile numbers are the opposite case. Italian mobiles used to be written with a leading 0 as well (0335, 0347 and so on), but that 0 was dropped around 2000. Today Italian mobile numbers start with the digit 3 and are usually ten digits long with no leading zero. So a mobile from abroad is simply +39 followed by the full number beginning with 3.
City codes you will actually use
Italian landline prefixes are organized geographically: codes starting 01 cover the northwest, 04 the northeast, 06 and 07 the center, and 08 and 09 the south and the islands. The two biggest cities have two-digit codes. Everyone else has three or four digits. Here are the ones you are most likely to need:
- Rome: 06
- Milan: 02
- Naples: 081
- Turin: 011
- Florence: 055
- Venice: 041
- Bologna: 051
- Palermo: 091
- Genoa: 010
- Verona: 045
So a Florence landline looks like +39 055 xxx xxxx when you dial it from abroad. A Milan hotel reservation might be +39 02 xxxx xxxx. If somebody gives you a number as "055 123 4567" and you are standing in New York, you dial 011 39 055 123 4567, or on a smartphone +39 055 123 4567. No digits removed.
Mid-sized cities usually have three-digit codes (Como is 031, Bergamo is 035), while smaller towns and provinces use four-digit ones (Siena is 0577, Lecce is 0832). The pattern is consistent: the whole code including the leading 0 is part of the dialable number from outside Italy. The full list of Italian area codes runs to a few hundred entries, and the total length of a landline number varies from place to place, so copy every digit you are given.
Italian mobile numbers
Every Italian mobile number starts with 3, and most run ten digits in total. The first three digits used to tell you which carrier owned the number (TIM, Vodafone, Wind Tre, Iliad, and various MVNOs). Since mobile number portability arrived in 2002, that is no longer reliable, so there is no point memorizing which prefix belongs to which operator.
A typical Italian mobile looks like 335 xxx xxxx, 348 xxx xxxx, or 393 xxx xxxx. From abroad you dial +39 followed by the full number. No leading 0. Easy case.
Emergency numbers in Italy
If you are traveling and you need help, the one number to remember is 112. This is the EU-wide emergency number, answered in Italian, English, and several other languages, and it will route you to the right service. Italy also still runs its historical emergency numbers; in regions where the single 112 call center is active, they are forwarded to it:
- 112 Carabinieri and the unified EU emergency line
- 113 State Police (Polizia di Stato)
- 115 Fire department (Vigili del Fuoco)
- 118 Medical emergencies and ambulance
All of them are free from an Italian SIM or landline. If you have signal but no credit, 112 still works. For non-urgent medical advice, a growing number of regions also answer 116117, the European non-emergency medical number.
Time zone and when to call
Italy is on Central European Time, which is UTC+1 in winter and UTC+2 in summer (Central European Summer Time). Italy follows European Union daylight saving rules, so clocks spring forward on the last Sunday of March and fall back on the last Sunday of October. In 2026 that fall-back date is October 25. For most of the year Italy is six hours ahead of Eastern Time and nine hours ahead of Pacific Time; in the one week between October 25 and the US change on November 1, the gap shrinks to five and eight hours.
Practical scheduling: if you are on the US East Coast and want to catch someone in Rome before dinner, call between 10 am and 1 pm your time. Italian lunch runs long. Business hours generally start around 9 am, and in many smaller cities, especially in the south, offices and shops close for a long lunch break in the early afternoon. They reopen in the late afternoon and run until 7 or 8 pm. Weekends tend to be family time, which is actually when international calls to relatives land best.
How calls to Italy actually get billed in 2026
Here is where the carrier picture matters. If you call Italy from a US mobile plan without an international add-on, pay-per-use rates from the big carriers can run from about a dollar to several dollars a minute, depending on the carrier and whether you reach a landline or a mobile. International add-on packages soften that but tie you into a monthly fee and often cap the included minutes. Hotel landlines are worse. A Wi-Fi calling plan from your carrier works when the signal is clean but still bills at carrier rates for international legs.
Phonecall prices a call to an Italian landline at $0.03 per minute and to an Italian mobile at $0.10 per minute, both listed on the rates page. Billing is per second, not per minute, so a 90-second call to a mobile to confirm a dinner reservation costs $0.15, not the price of two full minutes. There are no connection fees, no monthly commitment, no SIM to swap. The call runs over the internet from your browser, and the voice reaches the Italian side as a normal telephone call, so your grandmother's old landline in Palermo rings the way it always has.
A 20-minute weekly call to that landline comes to $0.60; the same call to a mobile is $2.00. On a carrier's pay-per-use rate of around $2 a minute, either one would be about $40. The math is boring and the implication is not.
New accounts get 30 seconds of free call time so you can test the audio quality on the number you actually need to reach, which matters more than any marketing claim about clarity. Try it on the Italian number that is giving you trouble, hear how it sounds, then decide.

Three situations where this matters
Calling family from the US. The classic case. You left Naples twenty years ago, your parents did not, and you want Sunday evening calls that do not require a credit card hostage situation. At $0.03 a minute to their landline, you can talk until the dog gets bored. The call lands as a regular phone call on their end, so there are no apps to install on their side.
Calling Italian offices from home abroad. Lawyers coordinating an inheritance in Lazio, buyers chasing a vineyard sale in Tuscany, art dealers checking provenance at a gallery in Milan. Business hours in Italy are narrow enough that you want calls to work the first time, and you do not want to be hunting for the right prefix format while the counterparty picks up and hangs up.
Travelers already in Europe or passing through. You landed at Fiumicino, your eSIM is tetchy, the hotel's number keeps timing out when you dial it from the airport Wi-Fi. Open the dialer in your browser, type the number including the leading zero (+39 06 ...), and call. If you are still planning the trip, the official tourism portal Italia.it covers the rest.
Troubleshooting a call that will not connect
Most failed calls to Italy fall into a handful of patterns.
You dropped the leading zero. The single most common mistake. If a Rome landline will not pick up, check that you dialed +39 06 and not +39 6. Add the zero back and try again.
You kept the leading zero on a mobile. The reverse mistake. Italian mobiles do not take a leading 0 anymore. If the number you have starts with a 0 in front of a 3, strip the 0.
The number uses an old nine-digit mobile format. Some older Italian mobile numbers are only nine digits long, left over from the early years of mobile service. They are valid, but if a number looks short, confirm with the person you are calling that it is complete.
You are dialing through an app that expects E.164 format. Some apps want the whole number without spaces or symbols, written as +390612345678. Others accept spaces or drop the +. If one format fails, try the other, but never remove the 0 after 39 on a landline.
Audio connects but one side cannot hear. This is almost always a network or firewall issue on your end, not Italy's. Switch Wi-Fi networks, turn off a VPN, or try a phone hotspot instead.
A few conventions that trip up Americans
Italians write phone numbers inconsistently. You will see 06.1234.5678, 06 1234 5678, 06-1234-5678, and 0612345678 all referring to the same number. The grouping is cosmetic. Only the digits matter.
The international access code from inside Italy is 00, not 011. So an Italian calling the US from a landline in Rome dials 00 1 followed by the US number. Americans in Italy using a US mobile with the + symbol do not need to worry about this.
Numbers starting with 8 are special-rate: toll-free numeri verdi start with 800 or 803, shared-cost numbers with 84, premium numbers with 89. Toll-free Italian 800 numbers are only free from inside Italy. If you call one from abroad it may not connect at all. If an Italian business lists both an 800 number and a geographic one, use the geographic number from the US.
San Marino uses the 0549 prefix when called from inside Italy, but from abroad it has its own country code, +378. Vatican City numbers, on the other hand, are integrated into +39 and generally take the form +39 06 698 followed by the rest of the number.
Why the browser call is the right default now
The service collapses a stack of annoyances into one tab. No SIM to buy, no eSIM profile to install, no account minimum, no second handset. It covers 218 countries with per-second billing, so Italy is one entry on a long rate sheet, and Italian landlines are among the cheapest destinations on it.
If your calling list extends past Italy, we publish companion guides for Spain, France, Germany, Switzerland, and the United Kingdom. Each handles the trunk zero in its own way, and Italy's rule is the least intuitive of the group.
Ready to call Italy
Sign up, dial +39 followed by the Italian number (keep that leading 0 on landlines), and the first 30 seconds are on us. If the audio sounds right, keep going at $0.03 a minute to landlines or $0.10 to mobiles. If it does not, close the tab and you are out nothing.
Buon viaggio and buona chiamata.
