Area Code 0825 – Avellino

Overview of Area Code 0825

Area code 0825 is a geographic National Destination Code (NDC) within the Italian public switched telephone network (PSTN), assigned under the national numbering plan administered by the Autorità per le Garanzie nelle Comunicazioni (AGCOM). It serves the province of Avellino, located in the Campania region of southern Italy. The code covers the provincial capital, Avellino, and its surrounding municipalities, including Atripalda, Mercogliano, Monteforte Irpino, and many smaller towns in the Irpinian hinterland.

Geographic Coverage and Administrative Jurisdiction

The 0825 area code is geographically bounded by the administrative province of Avellino. It does not cover the entire province uniformly; some municipalities at the provincial borders may use adjacent area codes (e.g., 081 for Naples, 0827 for Benevento, 0824 for Caserta). The code is used for both fixed-line PSTN and VoIP services that are registered to a physical address within the serving area. Mobile numbers in Italy always begin with 3 and are non-geographic, so they are not affected by this code.

Dialing Formats and Caller Instructions

For local callers within Italy, the area code is dialed in full, including the leading zero, followed by the subscriber number. The complete national significant number (NSN) for a fixed line in Avellino is 0825 XXXXXX, where XXXXXX is typically a 6-digit subscriber number. For example, a local call to a business in Avellino would be dialed as 0825 123456.

For international callers, the format is +39 825 XXXXXX (the leading zero is omitted when dialing from abroad). For instance, a caller from the United States would dial 011 39 825 123456, while a caller from the United Kingdom would dial 00 39 825 123456. When dialing from a mobile phone, the plus sign (+) can be used instead of the international access code.

Overlay and Numbering Considerations

As of the current numbering plan, there is no overlay code for 0825; the area code is exclusive to the Avellino region. Subscriber numbers within this code are typically 6 digits long, resulting in a total NSN length of 10 digits (including the leading zero). This structure is consistent with Italy's national numbering plan, which mandates that all geographic numbers have a total length of 10 digits (including the trunk prefix 0).

Callers should note that when dialing from a landline within the same local area, it may be possible to omit the area code, but this practice is becoming less common due to number portability and regulatory changes. To ensure reliable connectivity, it is recommended to always include the full area code.

For businesses and residents in Avellino, the area code is an integral part of their public identity, often used in marketing materials and official correspondence. Understanding the correct dialing format is essential for both domestic and international communication.
