0043

0043 is the international dialing code assigned to Austria, corresponding to the country code +43 in the ITU E.164 numbering plan. The sequence is commonly formed by the international access code (such as 00 in many countries) followed by 43, and on mobile devices the plus sign (+) can be used as an alternative prefix, yielding +43.

When dialing Austria from outside the country, one formats the number as international: the international prefix of the calling country followed by 43 and the local Austrian number. In domestic Austrian dialing, area codes typically start with a 0, which is omitted in international format. For example, a Vienna number written domestically as 01 234 5678 would be dialed internationally as 00 43 1 234 5678 or [phone].

Scope and usage: The +43 country code covers all Austrian telephone numbers, including landlines and mobile services. Austria’s national numbering plan assigns different area codes for regions; after the country code, the total number of digits varies by region due to the mix of area codes and subscriber numbers. The code 43 is reserved under the ITU framework and is recognized globally as Austria’s entry in the international dialing system.
