Regulatory and Technical Notes
This code is a geographic number under the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR). It is allocated to fixed-line services, primarily operated by A1 Telekom Austria and alternative carriers. As with all geographic codes in Austria, number portability applies, so a number with this prefix may be routed to a different operator or even a VoIP service, but the geographic tariff zone remains unchanged. The code is not overlaid with another area code; Mürzsteg uses 03859 exclusively.
For international callers, it is important to note that Austrian geographic numbers are typically charged at varying rates depending on the caller's country and the service provider. Calls to +43 3859 from abroad are not toll-free and may incur international long-distance charges.
