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.

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.

Best call windows

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.

Common mistakes when calling Austria

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.

11For business

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

Real PSTN presence — genuine geographic and mobile numbers.

FAQ

Austria +43 — FAQ

Why do Austrian phone numbers come in different lengths?expand_more

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

Just 1 — the only single-digit area code in the country.

How long can an Austrian area code be?expand_more

From one to four digits; regional capitals like Graz (316) sit in the middle, while villages such as Dornbirn (5572) use four.

How do I recognise an Austrian mobile?expand_more

It always uses a 06xx prefix (for example +43 664…), regardless of where the landline length varies.

Do I drop the 0 from a mobile prefix when calling from abroad?expand_more

Yes — 0664 becomes +43 664; you remove only the leading 0, never the 6.

Does the prefix tell me the carrier?expand_more

No — portability means a 0664 number once on A1 may now run on Magenta, Drei or an MVNO.

Yes — CET in winter, CEST (UTC+2) from late March to late October.

Which currency is used in Austria?expand_more

The euro (EUR, €).
