Area Code 3686 – Haus

Overview of Area Code 3686

Austrian area code 3686 is a geographic National Destination Code (NDC) assigned to the municipality of Haus im Ennstal, located in the Liezen District of the federal state of Styria (Steiermark). This code is part of the Austrian telephone numbering plan, which follows ITU-T E.164 recommendations. The region is situated in the scenic Enns Valley, surrounded by the Dachstein massif, and serves as a gateway to the Schladming-Dachstein ski area.

Geographic Coverage and Administrative Jurisdiction

The 3686 area code covers the town of Haus and its immediate surroundings, including the cadastral communities of Haus and Ennsling. Administratively, it falls under the jurisdiction of the Bezirk Liezen (district of Liezen), which is the largest district in Austria by area. The code is used for fixed-line telephone services provided by various operators, including A1 Telekom Austria, Magenta Telekom, and alternative carriers that offer local loop unbundling.

Dialing Formats and Instructions

For callers within Austria, the local dialing format requires the trunk prefix 0 followed by the area code and the subscriber number. For example, to call a fixed line in Haus, you would dial:

• 0 3686 12345 (from within Austria)

For international callers, the Austrian country code +43 replaces the leading zero. Thus, the same number would be dialed as:

• +43 3686 12345 (from outside Austria)

Subscriber numbers in this area typically consist of 4 to 6 digits, resulting in a total national significant number (NSN) length of 8 to 10 digits, including the area code but excluding the trunk prefix. When dialing locally within the same area code, callers may omit the area code and just dial the subscriber number, depending on the operator's settings.

Overlay and Numbering Considerations

As of the latest ITU-T national numbering plan updates, there is no overlay code for the 3686 area. The code is exclusively geographic, and number portability is available within Austria, allowing subscribers to retain their numbers when changing operators, even if the service is migrated to a VoIP platform. However, the geographic significance of the number remains tied to the original location.

Practical Information for Callers

When calling from abroad, ensure you have the correct international exit code (e.g., 00 from most European countries, 011 from the United States) before dialing +43 3686. For travelers in the region, local businesses and public services may list numbers with or without the area code; always include the area code when dialing from a mobile phone or from outside the immediate local area.
