Austria at a glance
The numbers and facts you need before you dial.
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 was assigned to Austria by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to 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.
Full example: +43 1 XXX XXXX — drop the local leading 0 when calling from abroad.
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.
Landline
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
