📍 Geographic Location of Dalaas
Geographic Overview
The Austrian area code 05585 is assigned to the Dalaas region, located in the westernmost state of Vorarlberg, within the political district of Bludenz. This mountainous area is part of the Montafon valley, a popular tourist destination known for its alpine scenery and outdoor activities. The code serves the municipality of Dalaas and its surrounding hamlets, including Wald am Arlberg and inner villages along the Klostertal. As a geographic prefix, 05585 is tied to the PSTN infrastructure of the region, although calls to these numbers may terminate on fixed-line or VoIP-based services.
Dialing Formats
For callers within Austria, the national trunk prefix 0 is used before the area code. The local subscriber number typically consists of 5 to 7 digits, making the complete national significant number (NSN) 10 or 11 digits long (including the leading 0). An example of a local number is 05585 12345.
For international callers, the country code +43 replaces the leading 0. The same subscriber number is dialed without the trunk prefix, resulting in the format +43 5585 12345. When dialing from a mobile phone, it is recommended to use the international format to avoid any ambiguity, especially when roaming.
Local and Foreign Caller Instructions
Residents and businesses within the Dalaas area can often dial the subscriber number directly without the area code if they are within the same local calling area. However, for calls from other Austrian regions or from abroad, the full national or international format must be used. No overlay codes have been introduced for this area, so the 05585 prefix remains unique to the region.
Regulatory and Technical Notes
As with all Austrian geographic codes, numbers under 05585 are allocated by the Rundfunk und Telekom Regulierungs-GmbH (RTR). They are subject to number portability, meaning that subscribers may retain their number when switching providers, but the geographic association remains. Calls to 05585 are typically charged at standard fixed-line rates, depending on the caller's tariff and the time of day. Emergency services (112) and other short codes are not affected by this prefix.
