Area Code 081 – Naples

Overview of Italy's 081 Area Code

The Italian national destination code (NDC) 081 is a geographic area code assigned to the city of Naples (Napoli) and its surrounding metropolitan area. As part of the Italian public switched telephone network (PSTN), this code follows the ITU-T E.164 numbering plan, ensuring international dialing compatibility. The 081 code covers the province of Naples, including the city center, the volcanic area of Mount Vesuvius, and numerous coastal towns such as Sorrento, Torre del Greco, and Castellammare di Stabia.

Geographic Coverage and Administrative Jurisdiction

The 081 area code is administered under the national regulatory framework of the Italian Communications Regulatory Authority (AGCOM). It serves a densely populated region in the Campania region, with Naples being the third-largest city in Italy. The code encompasses both the urban core and the sprawling suburban and semi-rural zones that form the metropolitan city of Naples. This includes key districts such as Vomero, Posillipo, and the historic center, as well as the islands of Capri and Ischia, which are part of the province and use the same code for fixed-line services.

Dialing Formats and Instructions

For callers within Italy, the national dialing format requires the trunk prefix 0 followed by the area code and the subscriber number. For example, a local Naples number might be dialed as 081 123 4567. When calling from abroad, the international format omits the leading zero: +39 81 123 4567. It is important to note that Italian fixed-line numbers are not portable across geographic areas; the 081 code remains tied to the Naples region, even if a subscriber moves to a different area code.

Overlay and Numbering Considerations

Unlike some countries that have introduced overlay codes, the 081 area code has not been overlaid. Subscribers in the Naples area continue to use eight-digit subscriber numbers (excluding the area code) within the 081 prefix. The total number length for a complete international dialing sequence is 11 digits (including the country code and the leading zero when dialed nationally). Callers should always include the area code when dialing from a mobile phone or another region, as Italian numbering regulations require it for all calls to geographic numbers.

Practical Guidance for Callers

For international callers, the correct sequence is 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 zero, and finally the subscriber number. For example, to call a Naples landline from the United States, one would dial 011 39 81 123 4567. For local callers within the 081 area, dialing the area code is still mandatory, even for calls within the same city, as per Italian dialing procedures. This ensures proper routing through the PSTN and avoids misdialing.
