How to call Austria (international dialing)

• Do not include a leading ‘0’ in the international call sequence – it is only used in Austria for domestic long distance calls and domestic calls to a mobile phone.
• A leading '+' in the phone number means 'dial your country's exit code'.
• Calling from a mobile phone: dial from on the country where you're currently located.
• Calling from a VoIP or satellite phone: dial from on the country where the phone is registered.

Austria’s country code may be mislabeled:

• Country code 0043 (exit code of ’00’ used in many European, Asian, and African nations followed by Austria’s country code of ’43’).
• Country code 01143 (exit code of ‘011’ used in the United States and Canada followed by Austria’s country code of ’43’).

When calling to a mislabeled country code, remove the exit code from the call sequence and replace it with the exit code of the “dialing from” country.

… to a mobile (cellular) phone

Use the same call sequence.

Mobile phone numbers are represented by area codes ‘650’ through ‘699’ inclusive. The leading ‘0’ is not included when calling from outside Austria.

When calling a mobile phone user, call to the country where the mobile phone is registered, regardless of where the person being called is currently roaming.

… to a VoIP phone

VoIP phone numbers based in Austria are accessed with the same call sequence as a regular landline phone.

When calling a VoIP phone user, call to the country where the VoIP phone is registered, regardless of where the person being called is currently roaming.

… to a satellite phone

Austria does not have a country-speicifc satellite phone system.

Most satellite phones operate on their country code – calls to these satellite phones follow their own call sequence.

… sending a fax

Use the same call sequence.
