Dialing Formats
When calling a Mettmach number from within Austria, you must use the national trunk prefix 0 followed by the area code and the subscriber number. For example, a local number might be dialed as:

From outside Austria, callers should use the international prefix (typically 00 or +) followed by the Austrian country code 43, the area code without the leading zero, and the subscriber number:

If you are calling from a mobile phone within Austria, you can also use the international format by replacing the leading zero with +43.

Austrian geographic numbers typically have a variable length. In the Mettmach area, subscriber numbers usually consist of 5 to 7 digits. The total length of the national significant number (NSN) after the trunk prefix is generally between 9 and 11 digits, depending on the subscriber number length. For example, +43 7755 12345 has an NSN of 10 digits (7755 + 6-digit subscriber number).
Caller Instructions
Local callers: If you are within the Mettmach area, you may be able to dial just the subscriber number without the area code, depending on your local exchange configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format.
International callers: Always use the plus sign (+) or the international access code of your country, followed by 43 and the area code without the leading zero. Ensure you omit the initial '0' of the area code when dialing from abroad.
