Area Code 5376 – Thiersee

Geographic Overview

Austrian area code 5376 is a geographic National Destination Code (NDC) assigned to the Thiersee exchange area in the federal state of Tyrol (Tirol). This code serves the municipality of Thiersee and its surrounding villages, including Landl, Mitterland, and Vorderthiersee, situated in the Kufstein District near the Bavarian border. The region is known for its alpine landscape and proximity to the German town of Oberaudorf.

Dialing Formats

For callers within Austria, the national trunk prefix 0 is required before the area code. The local subscriber number (SN) typically consists of 5 to 7 digits. The complete national format is:

• 0 5376 [subscriber number] (e.g., 0 5376 12345)

For international callers, the Austrian country code +43 replaces the leading zero. The international format is:

• +43 5376 [subscriber number] (e.g., +43 5376 12345)

When dialing from a mobile phone within Austria, the same national format applies. It is important to note that the area code is mandatory even for local calls within Thiersee, as Austria uses closed dialing plans.

Regulatory and Technical Notes

The 5376 code is allocated by the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR) to fixed-line services. It is primarily used by traditional PSTN and VoIP providers. Number portability allows subscribers to retain their number when changing operators, but the geographic significance remains tied to the original exchange. As of recent years, there are no overlay codes planned for this area, so the 5376 prefix remains unique to the Thiersee region.

For businesses, using a local geographic number like 5376 can enhance trust among local customers and is often preferred for physical presence. However, many companies also adopt non-geographic or mobile numbers for broader reach. Callers from abroad should always use the international format, omitting the leading zero.
