This article details the use of telephone numbers in Austria.

There are no standard lengths for either area codes or subscribers' numbers in Austria, meaning that some subscribers' numbers may be as short as three digits. Larger towns have shorter area codes permitting longer subscriber numbers in that area. Some examples:

00     International call prefix
112    general emergency call
118xxx directory assistance services
122    fire
133    police
140    mountain rescue
144    medical emergency
147    telephone counseling for children (Rat auf Draht)
15xx   generic information services (time, ...)
01     Wien/Vienna
0316   Graz
0463   Klagenfurt
050x   virtual private network (VPN)
0512   Innsbruck
0662   Salzburg
0650   cell phones (Telering)
0660   cell phones (Drei)
0664   cell phones (A1)
0676   cell phones (T-Mobile)
0680   cell phones (BoB)
0681   cell phones (Yesss)
0688   cell phones (Tele2)
0699   cell phones (Orange Austria / Yesss)
0718   internet dial-up numbers
0720   location independent landline numbers

0800   national free call
00800  international free call
0804   internet dial-up numbers
08xx   service numbers
09xx   premium rate

The number-assignment of the cell phones can vary, due to number portability.

• Yesss and Tele2 are using the network-infrastructure of Orange. Yesss is a discount-offer of Orange.
• BoB is a discount-offer of A1 and therefore uses its network-infrastructure.
• Since 2006 Telering is fully owned by and integrated into T-Mobile and therefore uses its network-infrastructure.

In ascending numeric order

• ¹ Telering was bought by T-Mobile in 2005. As of 2006, Telering uses the network-infrastructure of T-Mobile. As a special requirement of the European commission, many of the former transmitters and frequencies previously operated by Telering were given to Orange and Drei.
• ² BoB is a discount service of A1, Yesss and Eety is a discount service of Orange. Schwarzfunk is a discount service of T-Mobile.

Due to number portability, the code is not a safe way to evaluate the provider of a phone number. The providers assign only in exceptional cases (special sort of custom numbers, more expensive) non-existing numbers with a different prefix, and this is handled similar as porting an existing number from the desired network. However, the providers still have the administrative sovereignty over their own prefix.
