Understanding International Dialing Codes
Before diving into the specifics of the country code +39 351, it’s essential to grasp the basics of international phone numbers. The plus sign (+) at the beginning of a number is the international access code, used to indicate that you are making a call to a different country. The numbers that immediately follow the plus sign are the country code, a unique identifier for each nation. For instance, the United States and Canada share the country code +1.
The subsequent digits are the national significant number, which typically includes an area or mobile network code and the individual subscriber’s number. The structure and length of these numbers can vary significantly from one country to another.
The Origin of the country code +39 351: A Tale of Two Countries
Herein lies a common point of confusion that is crucial to clarify. The country code for Italy is +39. The “351” that follows is a prefix for a mobile phone number within Italy.
However, it is important to note that +351 is the country code for Portugal. Therefore, a number formatted as +351 xxx xxx xxx would be a call or message from Portugal. The presence or absence of the “39” is the key differentiator.
For the purposes of this article, we are focusing on numbers that appear as +39 351 xxx xxxx. This format indicates a mobile phone number originating from Italy.
Italian Mobile Networks and the “351” Prefix
In Italy, mobile phone numbers are distinguished from landlines by their initial digit. All mobile numbers in Italy begin with the number “3”. Following this are two or three digits that historically indicated the specific mobile network operator. While number portability now allows users to switch carriers while keeping their number, these prefixes are still associated with their original network.
The “351” prefix is primarily associated with two major mobile network operators in Italy:
- Iliad Italy: A subsidiary of the French telecommunications company, Iliad entered the Italian market in 2018 and quickly gained a significant market share. Known for its competitive pricing and straightforward offers, Iliad is a popular choice for many Italians, including young people and budget-conscious consumers.
- Lycamobile Italy: Part of a global mobile virtual network operator (MVNO), Lycamobile focuses on providing low-cost national and international calls. Their services are particularly popular among expatriates, tourists, and individuals who frequently communicate with people in other countries.
Therefore, if you receive a communication from a number with the country code +39 351, it is highly probable that the person contacting you is a subscriber of either Iliad or Lycamobile in Italy.
Legitimate Reasons for Contact from a country code +39 351 Number

- Online Acquaintances: In the age of social media and online communities, it’s common to form friendships with people from around the world. Someone you’ve connected with online who resides in Italy might be reaching out.
- Vacation Rentals and Tourism: If you have booked accommodation in Italy through platforms like Airbnb or Vrbo, the owner or property manager might contact you from their Italian mobile number to coordinate your arrival or provide information.
Professional and Business Interactions
- Business Contacts: You may have professional colleagues, clients, or partners based in Italy. Communication via phone or messaging apps using their Italian mobile number is a standard business practice.

Staying Vigilant: Potential Scams Associated with International Numbers
While most international communications are legitimate, it is always wise to be cautious of unsolicited calls and messages from numbers you do not recognize, including those with the country code +39 351. Scammers often use international numbers to perpetrate various fraudulent schemes.
Common Phone Scam Tactics
- The “One Ring” Scam (Wangiri): In this scam, your phone rings once from an unknown international number and then disconnects. The scammer’s goal is for you to call the number back out of curiosity. These are often premium-rate numbers that will charge you exorbitant fees for the call, with the money going to the scammer.
- Impersonation Scams: Scammers may pose as representatives of well-known companies, financial institutions, or even government agencies. They might claim there is a problem with your account, a prize to be claimed, or a debt to be paid. Their ultimate goal is to trick you into revealing personal and financial information. Be particularly wary if the caller creates a sense of urgency or uses threatening language.
- WhatsApp and Messaging App Scams: Scammers frequently use messaging apps like WhatsApp to target potential victims. A common tactic is the “wrong number” scam, where they initiate a seemingly innocent conversation, build trust over time, and then attempt to solicit money or personal information. They may also send links to phishing websites or malware disguised as photos, videos, or documents. Another prevalent WhatsApp scam involves a message from an unknown number claiming to be a family member in distress who has lost their phone and needs urgent financial assistance.
Red Flags to Watch For
- Unsolicited Contact: Be immediately suspicious of any unexpected call or message from an international number you do not recognize.
- Urgency and Threats: Scammers often try to create a sense of panic to prevent you from thinking clearly.
- Requests for Personal or Financial Information: Legitimate organizations will rarely ask you to provide sensitive information via an unsolicited phone call or message.
- Poor Grammar and Spelling: While not always the case, many scam messages contain grammatical errors and awkward phrasing.
- Too-Good-To-Be-True Offers: If you are offered a prize you didn’t enter to win or a deal that seems unbelievable, it is almost certainly a scam.
How to Handle a Suspicious Call or Message from a country code +39 351 Number
If you receive a suspicious communication from a number with the country code +39 351, the best course of action is to be proactive in protecting yourself.
- Do Not Answer or Reply: If you do not recognize the number, let the call go to voicemail. Do not reply to suspicious text or WhatsApp messages.
- Do Not Call Back: Never call back a number that engages in the “one ring” tactic.
- Block the Number: Most smartphones allow you to easily block unwanted numbers, preventing them from contacting you again.
- Report the Number: On messaging apps like WhatsApp, you can report the number as spam.
- Verify Independently: If the caller claims to be from a specific company or organization, hang up and contact the organization directly using a phone number or website that you know is legitimate. Do not use the contact information provided by the caller.
