Understanding Austrian Phone Numbers

Austrian phone numbers follow a specific structure, though they can vary in length depending on the region and type.

The Leading Zero Rule

All Austrian phone numbers begin with a 0 when dialed domestically. This is a trunk prefix, not part of the actual phone number. When calling from overseas, you must:

  • Remove the leading 0
  • Replace it with +43

This is the single most important rule for calling Austria internationally.

Mobile Numbers

Austrian mobile numbers all start with 06:

  • Domestic Format: 06XX XXXXXXX (11-12 digits starting with 0650, 0660, 0664, 0676, 0677, 0678, 0680, 0688, or 0699)
  • International Format: +43 6XX XXXXXXX (10-11 digits after +43)
  • Common mobile prefixes: 0650, 0660, 0664, 0676, 0677, 0678, 0680, 0688, 0699
  • Example: 0664 1234 567 becomes +43 664 1234 567

Landline Numbers (Fixed Line)

Austrian landlines use area codes of varying lengths (1-4 digits) followed by local numbers:

  • Domestic Format: 0XXX XXXXXXX (variable total length)
  • International Format: +43 XXX XXXXXXX
  • Example: Vienna number 01 1234 5678 becomes +43 1 1234 5678

Note: Vienna has the shortest area code (01), while smaller towns have longer ones (up to 4 digits). The total number length varies.

Austria Area Codes Reference Table

Here are the most important Austrian area codes for major cities:

Area Code City International Format
01 Vienna (Wien) - Capital +43 1 xxxx xxxx
0316 Graz +43 316 xxxx xxxx
0732 Linz +43 732 xxxx xxxx
0662 Salzburg +43 662 xxxx xxxx
0512 Innsbruck +43 512 xxxx xxxx
0463 Klagenfurt +43 463 xxxx xxxx
04242 Villach +43 4242 xxxx xxxx
07242 Wels +43 7242 xxxx xxxx
02742 St. Pölten +43 2742 xxxx xxxx
03842 Leoben +43 3842 xxxx xxxx

Pattern to note: Vienna has the shortest area code (01). Other major cities have 3-4 digit area codes, while smaller towns typically have 4-5 digit codes.

Mobile vs. Landline: How to Tell the Difference

You can tell mobile from landline by the prefix:

  • Starts with 06 (or +43 6): Always a mobile number
  • Starts with 01, 02, 03, 04, 05, or 07: Always a landline number

This distinction matters because calling rates to mobiles are typically higher than landlines with most international calling services.

Common Mistakes to Avoid

Here are the most frequent errors when dialing the 43 country code:

  • Keeping the leading 0: The most common mistake. +43 01... is wrong; +43 1... is correct.
  • Confusing +43 with +49: +43 is Austria, +49 is Germany. Both countries speak German, so this is a common mix-up.
  • Wrong number length: Austrian numbers vary in length. Don't assume all numbers have the same digit count.
  • Confusing area codes: Vienna is 01 (not 001 or 010). Salzburg is 0662 (not 062 or 0662x).
  • Forgetting time zones: Austria is ahead of the Americas but behind Asia. Check the time before calling!
