Area Code 0774 – Rome

Overview of Area Code 0774

Area code 0774 is a geographic National Destination Code (NDC) within the Italian national numbering plan, assigned to the province of Frosinone in the Lazio region. While the label 'Rome' may appear in some databases due to the proximity to the capital, the 0774 code specifically serves the city of Frosinone and its surrounding municipalities, including Ceccano, Ferentino, Veroli, and others within the administrative province. The code is part of the PSTN (Public Switched Telephone Network) and is used for fixed-line services.

Geographic Coverage and Jurisdiction

The 0774 code covers the territory of the Province of Frosinone, which is located in the southern part of Lazio, about 75 kilometers southeast of Rome. The principal city, Frosinone, is the administrative capital, and the area is characterized by a mix of urban and rural communities. The code is allocated by the Italian Communications Regulatory Authority (AGCOM) and is administered by various local telecom operators, including TIM (Telecom Italia), Vodafone, Wind Tre, and Fastweb, among others.

Dialing Formats and Instructions

When calling a number within the 0774 area, the full national number includes the trunk prefix '0' followed by the area code and the subscriber number. The subscriber number length varies between 6 and 7 digits, making the total national significant number (NSN) length either 9 or 10 digits (excluding the leading '0' when dialing internationally).

• Local calls (within the same area code): In Italy, local calls typically require dialing the full number including the area code, even for calls within the same exchange. For example, to call a number in Frosinone from a landline in the same city, you would dial 0774 123456.
• National calls (from other Italian area codes): Dial the full number starting with the trunk prefix '0': 0774 123456.
• International calls (from outside Italy): Dial the international access prefix (e.g., 00 from most countries, or +), followed by Italy's country code +39, then the area code without the leading '0', and the subscriber number. For example, from the US you would dial 011 39 774 123456, or from a mobile phone +39 774 123456.

Overlay and Numbering Considerations

As of the latest AGCOM updates, there is no overlay code for the 0774 area. The numbering plan for Italy does not use area code overlays; instead, each geographic area has a unique NDC. However, number portability allows subscribers to retain their numbers when switching operators, but the geographic significance of the code remains tied to the original location.

Caller Instructions

For callers within Italy, it is essential to include the leading '0' when dialing the area code, as it is part of the national dialing plan. For international callers, the leading '0' is omitted, and the country code +39 is used. It is also important to note that Italian mobile numbers begin with '3' and are not affected by geographic codes, so calls to 0774 numbers are strictly for fixed-line services.
