📍 Geographic Location of Strobl
Geographic Overview
The Austrian area code +43 6137 is assigned to the Strobl telephone exchange area, located in the Salzkammergut region of Upper Austria (Oberösterreich). This code serves the municipality of Strobl, situated on the western shore of the Wolfgangsee, and its immediate surroundings, including the villages of Weißenbach and Gschwendt. Administratively, Strobl falls under the district of Salzburg-Umgebung (Flachgau) in the state of Salzburg, despite being geographically close to Upper Austrian towns like Bad Ischl.
Dialing Formats
For callers within Austria, the national trunk prefix 0 must be dialed before the area code. Thus, a local call to a subscriber in Strobl requires dialing 0 6137 followed by the subscriber's 5-digit local number. The complete national number has a total length of 10 digits (excluding the trunk prefix). For example, a local number such as 12345 would be dialed as 06137 12345 from anywhere in Austria.
For international callers, the Austrian country code +43 replaces the trunk prefix. The same local number would be dialed as +43 6137 12345 (or +43613712345 when the spaces are removed). It is important to note that the leading '0' of the area code is omitted when dialing from abroad.
Geographic Allocation and Numbering
Area code 6137 is a geographic code under the Austrian national numbering plan, which follows the ITU-T E.164 recommendation. The prefix is allocated to fixed-line services, typically provided by A1 Telekom Austria, Magenta Telekom, and other regional carriers. Subscriber numbers within this code are 5 digits long, giving a maximum capacity of 100,000 lines, though the actual number of active lines is far lower due to the rural nature of the area.
Since the liberalization of the Austrian telecom market, subscribers in Strobl may have ported their numbers to alternative providers, including VoIP or cable operators. However, the geographic significance of the code remains tied to the location, and number portability does not alter the dialing format.
