Overlay and Numbering Considerations
Currently, there is no overlay code for this area, meaning that local calls within the same geographic area can be made using only the subscriber number without the area code, depending on the specific local exchange configuration. However, for all calls from outside the immediate local area, the full area code is mandatory. As with all Austrian geographic numbers, the subscriber is associated with a fixed line, but number portability allows the number to be transferred to a different provider or even to a VoIP service, which may affect routing but not the dialing format.
