Caller Instructions
Callers from within Austria: Dial 0, then the area code 5573, followed by the subscriber number. Do not omit the leading 0 when calling from a mobile phone or a fixed line, as it is essential for routing.
Callers from outside Austria: Dial the international access code (e.g., 00 from most European countries, 011 from North America), then Austria's country code 43, then the area code 5573 (without the leading 0), and finally the subscriber number. For instance, a caller from Germany would dial 00 43 5573 12345.
Overlay and Numbering Considerations

For businesses in Hörbranz, using a local geographic number enhances trust with regional customers. For callers, it is important to note that calls to 5573 are charged according to the national fixed-line tariff, regardless of the caller's location within Austria, unless the call is made from a mobile network where different rates may apply.
