📍 Geographic Location of Caserta
Geographic Coverage and Administrative Jurisdiction
The Italian area code 0823 is a Geographic National Destination Code (NDC) assigned to the province of Caserta, located in the Campania region of southern Italy. The numbering area encompasses the city of Caserta and its surrounding municipalities, including but not limited to: Santa Maria Capua Vetere, Capua, Marcianise, Maddaloni, Aversa (partially), and the northern suburbs of Naples that fall within the province. The area is administered under the jurisdiction of the Campania regional authority and the Italian Communications Regulatory Authority (AGCOM).
Dialing Formats and Number Structure
For domestic calls within Italy, subscribers within the 0823 area must dial the full national significant number, which includes the trunk prefix 0 followed by the NDC and the subscriber number. The complete national format is 0 823 xxx xxxx (where 'x' represents the local subscriber digits). For international callers, the Italian country code +39 is used, followed by the NDC and subscriber number, omitting the leading trunk prefix. Thus, an international call to a Caserta landline would be formatted as +39 0823 xxx xxxx.
It is important to note that Italy does not use a trunk prefix for international dialing; the leading '0' is only used for domestic calls. Additionally, Italian geographic numbers are fixed at 9 to 11 digits in total, including the leading '0'. Subscriber numbers in the 0823 area typically range from 6 to 8 digits, depending on the specific exchange and the historical allocation.
Overlay and Numbering Plan Considerations
As of the current numbering plan, there is no overlay code for the 0823 area; the code is exclusively used for the Caserta province. However, due to the proximity to Naples, some municipalities historically served by the 081 code (Naples) may border the 0823 area. Callers should verify the correct area code when dialing to avoid misrouted calls. For local calls within the same area code, the full national number (including the '0' and area code) must still be dialed, as per Italian regulations that abolished local dialing without the area code.
Caller Instructions
- Domestic callers (within Italy): Dial 0 823 xxx xxxx.
- International callers (from abroad): Dial your country's international access code (e.g., 00 or +), then 39 823 xxx xxxx.
- Mobile callers within Italy: Same as domestic callers; dial the full national number.
For example, to call a business in Caserta with the number 123 4567, a caller from Rome would dial 0 823 123 4567, while a caller from the United States would dial 011 39 0823 123 4567.
Service and Usage
The 0823 area serves both residential and business customers, including public administration offices, the historic Royal Palace of Caserta (a UNESCO World Heritage site), and various commercial enterprises. The code is also used for fixed-line services provided by Telecom Italia (TIM), Vodafone Italia, Wind Tre, and other alternative carriers, as well as VoIP services that offer geographic numbers. As with all Italian geographic codes, number portability allows subscribers to retain their 0823 numbers when switching providers, but the number remains geographically tied to the Caserta exchange area.
