📍 Geographic Location of Rohrau
Overview of Area Code 2164
Austrian area code +43 2164 is a geographic prefix assigned to the municipality of Rohrau and its surrounding administrative area in the state of Lower Austria (Niederösterreich). This code falls under the national destination code (NDC) framework defined by the ITU-T E.164 standard, specifically allocated to the Carnuntum region near the Slovak border. The service area includes the cadastral communities of Rohrau, Gerhaus, and Hollern, with the historic Rohrau Castle (Schloss Rohrau) as a notable landmark.
Geographic Coverage and Jurisdiction
The +43 2164 prefix is administered by the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR-GmbH) and is assigned to fixed-line PSTN services. It covers a predominantly rural district within the Bruck an der Leitha political district, approximately 40 kilometers southeast of Vienna. Local exchanges are connected to the Austrian fiber-optic backbone, supporting both traditional copper-line telephony and modern VoIP-based fixed-line services.
Dialing Formats and Instructions
For callers within Austria, the national trunk prefix 0 must be dialed before the area code, followed by the subscriber number. The complete national format is 0 2164 xxxxx, where the subscriber number typically consists of 4 to 6 digits. For example, a local number might be dialed as 0 2164 12345.
International callers must replace the leading zero with the Austrian country code +43, resulting in the format +43 2164 xxxxx. For instance, from abroad, the same number would be dialed as +43 2164 12345. When calling from a mobile phone within Austria, the full national number (including the leading 0) is required, as mobile networks do not recognize abbreviated local dialing.
Overlay and Numbering Considerations
Currently, there is no overlay code for the 2164 area. Subscribers in Rohrau retain the exclusive use of this prefix, and number portability allows users to switch between fixed-line operators while keeping their geographic number. However, if a number is ported to a VoIP provider, the geographic association may no longer reflect the physical location of the line, which is a common practice under Austrian number portability regulations.
Practical Information for Callers
- Local callers: Within the same area code, dial the subscriber number directly without the area code (e.g., 12345).
- National callers: Dial 0 2164 followed by the subscriber number.
- International callers: Dial +43 2164 followed by the subscriber number, omitting the leading zero.
- Emergency services: Always dial the national emergency numbers (112 or 133/144) regardless of the area code.
