Caller Instructions
- Local callers (within Austria): Dial 0 7758 [subscriber number].
- International callers: Dial the international access prefix (e.g., 00 from most European countries, or + from mobile phones), followed by 43 7758 [subscriber number].
- Callers from Germany (adjacent country): Due to the proximity, some cross-border dialing agreements may apply, but standard international dialing is always reliable.
Numbering Plan Considerations
As a geographic code, the 7758 prefix is tied to a fixed-line telephone exchange. However, number portability allows subscribers to retain their numbers when switching providers, including to VoIP or mobile services, but the geographic association remains for administrative purposes. There are no overlay codes currently in effect for this area, so local calls within the Obernberg am Inn region are typically charged as local calls, while calls from other Austrian regions are subject to national long-distance tariffs.
For businesses and residents, it is important to note that the code is used exclusively for fixed-line services; mobile numbers in Austria are assigned distinct non-geographic prefixes starting with 6 (e.g., 660, 664, etc.).
