Area Code 4276 – Feldkirchen in Kärnten

Overview of Area Code 4276

Area code 4276 is a geographic National Destination Code (NDC) assigned to the fixed-line telephone network of Feldkirchen in Kärnten, a district capital in the Austrian state of Carinthia (Kärnten). This code follows the ITU-T E.164 numbering plan and is used for PSTN (Public Switched Telephone Network) and VoIP services that are registered to a physical address within this specific geographic area.

Geographic Coverage and Administrative Jurisdiction

The 4276 prefix serves the political district of Feldkirchen, which includes the town of Feldkirchen itself and its surrounding municipalities, such as Ossiach, Steindorf am Ossiacher See, Himmelberg, and Glanegg. The area is situated in the southern part of Austria, near the scenic Ossiacher See lake. The code is administered by the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR) and is allocated to fixed-line operators providing services in this region.

Dialing Formats and Instructions

For callers within Austria, the national trunk prefix 0 must be dialed before the area code. Thus, a local call to a subscriber in Feldkirchen requires dialing 0 4276 followed by the subscriber's local number, which typically has a length of 6 to 7 digits. The complete national significant number (NSN) is 10 digits, including the leading '0'.

For international callers, the Austrian country code +43 replaces the leading '0'. Therefore, an international caller should dial +43 4276 followed by the local subscriber number, omitting the trunk prefix. For example, if a local number is 12345, the international format would be +43 4276 12345.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Feldkirchen area; the 4276 code is exclusive to this geographic region. However, number portability allows subscribers to retain their 4276 numbers when switching between fixed-line operators, even if the service is delivered over VoIP. This means that a number with this prefix may not always be physically located in the area, but it remains associated with the original geographic allocation for routing purposes.

Caller Guidance

Local callers within the same area code can often dial the subscriber number without the area code, but this is operator-dependent. To avoid confusion, it is recommended to always use the full national format. For foreign callers, it is essential to use the international format +43 4276 and to check time zone differences (Austria is UTC+1, UTC+2 in summer).
