Area Code 4279 – Sirnitz

Overview of Area Code 4279

Austrian area code 4279 is a geographic National Destination Code (NDC) assigned to the town of Sirnitz and its immediate surroundings in the federal state of Carinthia (Kärnten). Sirnitz is a small village located in the municipality of Albeck, within the district of Feldkirchen. The code is used for fixed-line telephone services connected to the public switched telephone network (PSTN) and is allocated to the local exchange serving this rural, alpine region.

Geographic Coverage and Administration

The 4279 prefix covers Sirnitz and the adjacent hamlets and farms that form part of the Albeck municipal area. This region is situated in the Gurktal Alps, near the border with the state of Styria. Because of the mountainous terrain, the exchange area is relatively small, and the number of subscribers is limited. The administrative responsibility for telecommunications in Austria lies with the national regulatory authority, Rundfunk und Telekom Regulierungs-GmbH (RTR), which allocates numbering resources according to the national numbering plan.

Dialing Formats

For callers within Austria, the local number must be dialed with the trunk prefix 0 followed by the area code and the subscriber number. The full domestic format is:

• 0 4279 XXXXX (where XXXXX is the 5-digit local subscriber number)

For international callers, the country code for Austria is +43, and the leading trunk prefix '0' is omitted. The international format is:

• +43 4279 XXXXX

For example, if a local subscriber number is 12345, a call from Vienna would be dialed as 04279 12345, while a call from Germany would be dialed as +43 4279 12345.

Caller Instructions

When calling a Sirnitz number from abroad, always replace the initial '0' of the domestic prefix with the international access code of your country (e.g., 00 from most European countries, 011 from the United States) followed by Austria's country code 43. From mobile phones, the plus sign (+) can be used instead of the international access code. It is important to note that area code 4279 is not an overlay; it is the sole geographic code for Sirnitz, and there are no plans for an overlay in this rural area.

Service and Usage

Subscribers in this area are typically residential and small business users. As with most Austrian fixed-line numbers, calls to 4279 numbers are charged at standard national rates when dialed from within Austria. International rates vary depending on the caller's provider. The code is not used for premium-rate services or emergency services; those have dedicated short codes.
