Italy International Area Code: Everything You Need to Know About Dialing +39

The international area code for Italy is +39. If you are trying to call a landline or a mobile phone in Italy from another country, you must dial this country code before the local number. Unlike many other nations where area codes are separated from the country code by distinct lengths or fixed prefixes, Italy requires you to keep the area code—such as 06 for Rome or 02 for Milan—attached to the subscriber number even when calling from abroad.

What it means / how it works

An international area code, formally known as a country calling code, is a numerical prefix used to route telephone calls and SMS messages from one country to another through the international public telecommunication numbering plan. For Italy, that prefix is +39.

When telecommunication systems process a call, the country code tells the network which nation the call belongs to. Once the call reaches Italy's national telecommunications network, the remaining digits direct the call to the correct city, region, or mobile network operator.

Italy’s numbering system has a distinct historical quirk: unlike countries that drop the leading zero of an area code when dialing internationally, Italian numbers retain the initial zero. For example, a landline in Rome uses the local area code 06. If you are calling from outside Italy, you dial +39 06 followed by the local subscriber number. If you drop that zero, the call will fail.

Landline codes vary by geographic location, while mobile numbers use specific operator prefixes rather than geographic regions. Mobile prefixes in Italy typically start with 3 (for example, numbers beginning with +39 340, +39 335, or +39 391).

Practical scenarios

• Calling an Italian hotel or restaurant from the United States or Canada using an international landline or mobile carrier.
• Sending an SMS message to an Italian mobile subscriber from a foreign smartphone or a digital web-based messaging service.
• Entering an Italian phone number into an online account registration form or e-commerce checkout page that requires international format.
• Setting up two-factor authentication or receiving one-time passwords (OTP) on an Italian mobile phone number while traveling or working abroad.
• Dialing Italian business contacts for remote work, freelance projects, or international supply chain communication.
• Troubleshooting why a verification code or automated SMS from an app is not reaching an Italian number due to missing country prefixes.
• Configuring VoIP (Voice over Internet Protocol) softphones or business communication software to handle inbound and outbound calls to Italian numbers.

Step-by-step

Dialing an Italian phone number correctly depends on whether you are using a landline, a mobile phone, or dialing from a specific region. Follow these steps to ensure your call or message connects successfully.

1. Identify your exit code: If you are calling from a landline or mobile phone inside a country that uses an international prefix other than the plus sign, dial that exit code first. For example, callers in the United States and Canada dial 011, while callers in most European countries dial 00. Alternatively, pressing and holding the "0" key on a mobile phone will automatically generate the "+" symbol.
2. Enter the Italy country code: Input the country code for Italy, which is 39. If you used the plus sign shortcut on a mobile device, your string will look like +39.
3. Include the leading zero: Unlike many other international dialing conventions, do not drop the zero from the local area code or mobile prefix. If the local number starts with 0, keep it. For example, dial +39 02 for Milan or +39 340 for a mobile line.
4. Dial the subscriber number: Enter the remaining local digits assigned to the individual, business, or mobile device. Italian landline numbers vary in length, while mobile numbers usually consist of 9 or 10 digits following the prefix.
5. Check the complete sequence: Review the final string before placing the call. A correct international format for a Roman landline should look like +39 06 XXXXXXXX, and a mobile number should look like +39 3XX XXXXXXX.

Safety/privacy/legal

When handling international telephone numbers, data privacy and communication security are critical considerations, especially when dealing with online verification, account authentication, and digital platforms.

When you register online accounts using phone numbers—whether Italian numbers or numbers from other regions—platforms often require SMS verification via an OTP (one-time password). Publicly shared phone numbers found on free online SMS websites expose your authentication codes to anyone viewing the public inbox. This introduces severe privacy risks, as third parties can potentially intercept password resets or access accounts linked to those numbers.

For users seeking enhanced privacy during online account creation, testing, or app registration without exposing personal SIM cards, dedicated solutions can be utilized. For users who need a paid private option instead of a public inbox, PVACodes can be considered as one SMS verification solution, depending on the country, app, and current availability.

Additionally, telecommunication regulations within the European Union, including GDPR (General Data Protection Regulation), govern how European phone numbers and personal data are collected, stored, and processed by businesses. Always review the privacy policy of any platform collecting your phone number to ensure your data is handled securely and in compliance with regional standards.

Best alternatives

Depending on your exact requirement—whether you need to place traditional voice calls, send text messages, or receive verification codes for online applications—several approaches can be taken:

• Traditional Mobile Roaming: Using your existing mobile carrier's international roaming plan to send texts and make voice calls while in Italy or calling Italian numbers.
• VoIP and Calling Apps: Utilizing internet-based communication applications such as Skype, WhatsApp, or Google Voice to place cost-effective international voice calls to Italian landlines and mobiles.
• Local Italian SIM Cards: Purchasing a prepaid physical SIM card or eSIM from Italian mobile network operators like TIM, Vodafone Italy, Wind Tre, or Iliad for local rates during extended stays.
• - Dedicated SMS Verification Platforms: Using specialized web services designed to receive temporary verification codes, manage multiple online accounts, or handle automated OTP testing securely.

Frequently Asked Questions

What is the country code for Italy?

The country code for Italy is +39. It must be dialed at the beginning of any international call or SMS sent to an Italian phone number from outside the country.

Do I need to drop the zero when dialing Italy internationally?

No. Unlike many other nations where the leading zero of a city code is omitted for international calls, Italy requires you to keep the initial zero (e.g., +39 06 for Rome).

How do I dial an Italian mobile number from the US?

Dial the US exit code (011), followed by Italy's country code (39), followed by the mobile prefix and subscriber number. On a mobile phone, simply dial +39 followed by the mobile number (e.g., +39 333 XXXXXXX).

What are the major city area codes in Italy?

Major Italian cities have distinct landline area codes that start with zero. For example, Rome is 06, Milan is 02, Naples is 081, Turin is 011, and Florence is 055.

Why is my call to Italy failing?

Calls usually fail if the international prefix (+ or 00/011) is missing, if the leading zero of the Italian area code was incorrectly dropped, or if your mobile carrier has not enabled international direct dialing on your plan.

Are Italian mobile numbers longer than landlines?

Italian mobile numbers typically have fixed lengths starting with a 3 followed by 9 digits total, whereas landline subscriber numbers can vary in length depending on the size of the city or region.
