📍 Geographic Location of Doren
Geographic Overview
The Austrian area code 05516 is a geographic National Destination Code (NDC) assigned to the municipality of Doren, located in the Bregenz district of the westernmost Austrian state of Vorarlberg. Doren is situated in the Bregenzerwald region, near the border with Germany and the Swiss canton of St. Gallen. The code serves the local exchange area covering Doren and its immediate surroundings, including the villages of Sulzberg, Riefensberg, and parts of the neighboring communities. As a geographic code, 05516 is used exclusively for fixed-line PSTN and VoIP services that are registered to physical addresses within this area.
Dialing Formats
For callers within Austria, the national trunk prefix 0 must be dialed before the area code. The complete national format is:
- 0 5516 [local subscriber number] (e.g., 0 5516 12345)
For international callers, the country code for Austria is +43, and the leading trunk prefix is dropped. The international format is:
- +43 5516 [local subscriber number] (e.g., +43 5516 12345)
Local calls within the Doren exchange area may be placed using only the subscriber number, depending on the specific carrier's dialing plan. However, for clarity and to avoid misdialing, it is recommended to always use the full national or international format.
Caller Instructions
Domestic callers from outside the 05516 area must dial the full national number: 0 5516 [subscriber number]. International callers should replace the leading zero with the +43 country code: +43 5516 [subscriber number]. When dialing from a mobile phone in Austria, the same national format applies, and the call will be routed as a geographic fixed-line call, which may be subject to different tariffs than mobile-to-mobile calls.
Overlay and Numbering Considerations
As of the current numbering plan, there is no overlay code for the 05516 area. The code is unique to the Doren region, and no additional area codes have been assigned to the same geographic area. Subscriber numbers within this code typically range from 4 to 7 digits, depending on the historical allocation and the operator's capacity. The total length of a national significant number (NSN) for Austria is 10 to 12 digits, including the area code and subscriber number, excluding the trunk prefix.
Regulatory and Technical Notes
The allocation and management of geographic area codes in Austria are overseen by the national regulatory authority, Rundfunk und Telekom Regulierungs-GmbH (RTR), in accordance with ITU-T E.164 recommendations. Fixed-line numbers under 05516 are typically assigned to incumbent and alternative carriers, and number portability allows subscribers to retain their numbers when changing providers, provided they remain within the same geographic area. VoIP services registered to addresses in the Doren area may also use this code, but the physical location of the caller may affect emergency services routing.
