Austria at a glance
Die Zahlen und Fakten, die Sie vor dem Wählen benötigen.
What is the country code for Austria?
Austria's country code is +43. Dial it after your exit code to reach any Austrian landline or mobile. The wrinkle that trips people up: Austria doesn't fix its number length. A big-city line is short, a rural line is longer, because the area code itself grows the further you get from Vienna. Domestically, every number wears a trunk 0 that you drop when you go international.
Code +43 zugewiesen wurde Austria von der ITU im Rahmen des E.164-Plans. Der “+” bedeutet „Wählen Sie Ihren lokalen internationalen Exit-Code“; Halten Sie auf einem Mobiltelefon die Taste gedrückt 0 um es zu tippen.
Alle vier bedeuten dasselbe – sie verbinden Ihren Anruf mit Austria.
How to call Austria from anywhere
Dial your exit code, then 43, then the area code or mobile prefix with its leading 0 removed, then the subscriber number. Just remember the area code's length isn't fixed — Vienna gives you one digit, a Tyrolean village four.
Vollständiges Beispiel: +43 1 XXX XXXX — Weglassen der lokalen führenden 0, wenn Sie aus dem Ausland anrufen.
Austria phone number format explained
This is the part to slow down for. Landline length floats with the area code — Vienna runs on a single 1, regional capitals on 3 digits, and small towns on 4. Add the subscriber number and the total length shifts city to city. Mobiles, by contrast, are uniform: a 4-digit 06xx prefix every time.
Festnetz
0 + area code + subscriber. Vienna = 01 + subscriber; regional cities = 0XXX + subscriber; smaller towns push to 0XXXX. International: +43 1 1234567 (Vienna) or +43 316 123456 (Graz).
Mobile
06XX + subscriber at home (e.g., 0664 123456). International: +43 664 123456. Every Austrian mobile begins with 06 — the one constant in a variable system.

Austria mobile network prefixes
The prefix after +43 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
A1 Telekom Austria
typical prefix 0664 (market leader)
Magenta Telekom
typical prefix 0676
Drei (Hutchison 3)
typical prefixes 0660 / 0699
Austria time zone
Austria uses Central European Time (CET, UTC+1), switching to CEST (UTC+2) from late March to late October.
Austrian offices run a punctual 9-to-5, so an East Coast caller lands best between 14:00 and 17:00 CET (your 08:00–11:00 ET) before Vienna winds down. From the UK you share nearly the entire working day — just allow for the one-hour CET lead.

Almost every failed international call is a formatting issue, not a network issue.
Assuming a fixed number length: this is Austria's signature trap. Area codes run 1 to 4 digits, so total length changes from Vienna to a mountain village
count the actual digits you're given rather than padding or trimming to a habit.
Keeping the leading 0: drop the trunk 0 after +43 (dial +43 1…, never +43 01…)

Tips to reduce the cost of calling Austria
Carry Austrian calls over VoIP or a virtual +43 line instead of paying carrier international rates.
Prefer fixed lines
a Vienna 1 or Graz 316 number usually terminates cheaper than a 0664 mobile.
Sidestep 0900 premium ranges; they bill at service rates, not ordinary call rates.
Keep calls inside the shared CET workday so missed calls don't bounce back at higher tariffs.
Why businesses get a Austria virtual number
Austrians put weight on a settled, local presence, and a +43 caller ID — ideally a recognisable Vienna 1 line — signals exactly that. The right area code can even place you in a customer's own Bundesland.
Higher answer rates
Higher answer rates — a domestic +43 ID gets picked up where a foreign number gets declined.
Lower trust friction
Lower trust friction — a Vienna 1 line reads as an established, long-standing operation.
Cheaper inbound
Cheaper inbound — calls terminate over IP rather than international PSTN.
Centralized routing
Centralized routing — pull calls from every Bundesland into one team, wherever based.
Faster expansion
Faster expansion — enter the Austrian market without local infrastructure.
Real PSTN presence

Austria +43 — FAQ

Because area codes range from 1 digit (Vienna) to 4 digits (small towns), so the overall number length shifts with the location.
How do I call Austria from the United States?expand_more
Dial 011, then 43, then the area code or mobile prefix with the leading 0 removed, then the subscriber number.
What is Vienna's area code?expand_more
