Area Code 0575 – Arezzo

Geographic Coverage and Administrative Jurisdiction

The Italian area code 0575 is a geographic National Destination Code (NDC) assigned to the province of Arezzo, located in the eastern part of Tuscany, central Italy. The code serves the city of Arezzo itself, which is the provincial capital, as well as numerous surrounding municipalities and rural areas within the provincial boundaries. Key towns and villages covered by this prefix include Sansepolcro, Bibbiena, Cortona (partially), Montevarchi, and Poppi, among others. The administrative jurisdiction aligns with the Province of Arezzo, which is part of the Tuscany region. The area is known for its historical heritage, including the Piazza Grande and the Basilica of San Francesco, and is an important commercial and cultural center.

Dialing Formats and Number Structure

Within Italy, calls to numbers in the 0575 area code require dialing the full national significant number (NSN), which includes the trunk prefix 0 followed by the area code and the subscriber number. The NSN for geographic numbers in Italy is typically 9 to 10 digits long, excluding the international prefix. For local calls within the same area code, the use of the area code is still mandatory, as per the Italian numbering plan, which does not allow local dialing without the full NSN. Therefore, a local call from a fixed line in Arezzo to another fixed line in Arezzo would still require dialing 0575 followed by the subscriber number.

For international callers, the format is: +39 0575 XXX XXX, where +39 is the country code for Italy, and the leading 0 of the area code is dropped when dialing from abroad. For example, a typical subscriber number might be 0575 123456 (domestic format) or +39 0575 123456 (international format). It is important to note that the total length of the subscriber number after the area code can vary, but the complete national number (including the leading 0) is always 10 digits for geographic numbers in this range.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 guidelines and the Italian Communications Regulatory Authority (AGCOM) regulations, there is no overlay code for the 0575 area. The code is exclusively assigned to the province of Arezzo, and no new geographic codes have been introduced in this region. Number portability is available for fixed-line services, allowing subscribers to retain their numbers when changing operators within the same geographic area. However, porting does not change the geographic association of the number.

Caller Instructions

• Local callers (within Italy): Dial 0575 followed by the subscriber number. Example: 0575 123456.
• International callers: Dial your country's international access code (e.g., 00 from most European countries, 011 from North America), then 39 (Italy's country code), then 0575 (including the leading 0), and the subscriber number. Example: 00 39 0575 123456 or 011 39 0575 123456.
• Mobile callers within Italy: Always dial the full NSN, including the leading 0, as mobile networks require it.

This area code is part of the Italian public switched telephone network (PSTN) and is also used by VoIP services that provide geographic numbers. When calling from abroad, ensure you use the correct international prefix for your country, as it varies.
