Country telephone code 39 is the international dialing prefix for Italy, connecting callers worldwide to Italian landlines and mobile networks. Whether you're booking a hotel in Rome, calling a business partner in Milan, or reaching out to family abroad, getting the dialing sequence right prevents failed connections and unexpected carrier fees.
To dial Italy from outside the country, start with your international exit prefix, enter code 39, followed by the subscriber number, which includes the area code. Unlike many other nations where area codes are separated from the subscriber number, Italy's domestic numbering plan integrates the trunk prefix directly into the dialed number, meaning you always keep the initial zero of the city code.
How to Dial Italy From Abroad
Placing a call to Italy requires a specific sequence depending on your departure country and whether you're using a landline or a mobile phone.
When calling from a landline outside Italy, you must input your country's international exit code first. For callers in the United States and Canada, this is 011. Callers originating from the United Kingdom or most of Europe use 00. BBC has also covered this fascinating topic in great detail.
Here is the exact formula for international calls:
- Dial the international exit code (e.g.,
011from the US,00from the UK). - Enter country code 39.
- Dial the full Italian telephone number, including the original zero of the city or mobile code (e.g.,
06for Rome or02for Milan).
For example, calling a Rome landline from the United States looks like this: 011 39 06 12345678.
When calling from a mobile phone anywhere in the world, you can typically substitute the international exit code with the plus sign (+). You'd dial +39 06 12345678 directly on your smartphone keypad. Mobile networks recognize the plus sign and automatically route the call through international gateways.
The Structure of Italian Phone Numbers
Italian telephone numbers have a unique structure governed by the Ministero delle Imprese e del Made in Italy. Unlike North American numbering plans where numbers have a fixed length, Italian numbers vary in total length depending on the destination type.
Italian landline numbers always begin with a zero. The initial digit indicates the geographic zone or service type:
- 02 serves Milan and surrounding Lombardy regions.
- 06 covers Rome and the Lazio region.
- 081 routes calls to Naples and Campania.
- 055 directs traffic to Florence and Tuscany.
Mobile phone numbers in Italy do not use geographic area codes. Instead, they always begin with specific operator prefixes starting with a 3, such as 330, 340, 360, or 380. Even when dialing an Italian mobile phone from abroad, you must include the country code 39, followed by the mobile prefix and the subscriber number (e.g., +39 340 1234567, keeping the leading 3).
Common Mistakes When Dialing Code 39
Callers frequently encounter errors when dialing Italian numbers due to a few persistent pitfalls. Understanding these mistakes saves time and prevents connection failures.
The most common error is dropping the leading zero on the city code. In many countries, international dialing requires dropping the domestic trunk prefix (the leading zero). Italy is an exception. You must retain the initial zero on Italian landline codes (such as 06 for Rome or 02 for Milan). Dialing +39 6 12345678 will fail; you must dial +39 06 12345678.
Another frequent mistake involves confusing toll-free or special service numbers with standard geographic lines. Numbers starting with 800 (toll-free) or 199 (premium services) cannot be dialed directly from outside Italy using standard international formats. If you try to dial an Italian toll-free number from abroad, the call won't connect unless the business provides an alternate international routing number.
Finally, check your carrier's international dialing rates before picking up the phone. Traditional landlines and older mobile plans charge steep per-minute rates for calls to Italy. Many users switch to internet-based VoIP services or dedicated calling apps to reduce expenses on long-duration conversations.
Cost Considerations and Alternative Calling Methods
Placing direct international calls through traditional cellular carriers can lead to surprisingly high bills. Telecom providers often tack on substantial per-minute surcharges for calls terminating on foreign networks.
If you make frequent calls to Italy, consider these cost-effective alternatives:
- VoIP and Messaging Apps: Services like WhatsApp, FaceTime Audio, and Skype allow you to call other app users over Wi-Fi or mobile data for free, regardless of geographic distance.
- International Calling Cards and Add-ons: Major mobile carriers offer monthly international calling packages that drop per-minute rates significantly for a flat fee.
- SIP Trunking for Businesses: Companies operating customer support centers or sales branches in Italy utilize cloud communications platforms to secure local Italian phone numbers, allowing customers to call them at local rates.
You can verify global numbering standards and updates directly through the International Telecommunication Union, which manages the global allocation of country codes.
Frequently Asked Questions
Do I need to drop the zero when dialing Italian mobile numbers?
No. Unlike landlines in some other nations, Italian mobile numbers always retain their leading digit (which is a 3, such as 340 or 339). When calling an Italian mobile phone from abroad, dial +39 followed immediately by the full mobile number, including the starting 3.
Can I use code 39 to call Vatican City?
Yes. Vatican City shares the Italian telephone numbering plan. Calls to Vatican numbers use country code 39 and are dialed using the Italian prefix 06 for Rome, followed by the local Vatican subscriber numbers.
Why won't my call to an Italian toll-free number connect?
Italian toll-free numbers (starting with 800 or numero verde) are restricted to domestic callers within Italy. They cannot be reached from international networks unless the company publishes a dedicated standard geographic number for foreign callers.
How can I verify if an Italian phone number is valid?
You can check the format of Italian numbers against guidelines provided by the Italian Regulatory Authority for Communications. Valid landline and mobile numbers follow strict digit-count rules enforced across the national telecommunications grid.
