Austria phone numbers

International +43 664 123456, E.164 +43664123456

The numbering plan of Austria: formats, lengths, the regular expression for each line type and the prefix blocks allocated to each carrier, as ITU publishes it. A pattern says what a number looks like and where it was allocated; whether it is in service, and who serves it today, is a different question (below).

Test a pattern

Tick the line types you accept, copy the combined pattern, and paste numbers to see which range each one falls in. Numbers are reduced to their national digits first (no spaces, no +43, no trunk prefix 0); nothing leaves your browser.

Walk the prefixes

Type the first digits of a number in national form, or tap them: the operators holding blocks under those digits, then the block a full prefix falls in. 37 blocks held by 4 operators are on record.

Line types and their regular expressions

Match each pattern against the national significant number: digits only, without the trunk prefix 0 and without +43. The patterns follow the national numbering plan and are anchored here.

Carrier prefix blocks

The operator each prefix block was allocated to, in national form, from the published allocation records for +43. Numbers are portable, so this is the original allocation, not necessarily the carrier serving a number today.

Questions developers ask

How many digits does a phone number in Austria have?
Mobile numbers have 7 to 13 national digits. Fixed line numbers have 4 to 13 national digits (3 when dialled locally). That is the national number, without the country code +43 and without the trunk prefix 0.
What is the country code for Austria?
+43. From abroad, dial your own exit code, then 43, then the national number without its trunk prefix 0. From inside Austria, the exit code for international calls is 00.
Which prefixes are mobile numbers in Austria?
Mobile numbers start with 064, 065, 066, 067, 068 or 069 in national form; the mobile regular expression on this page gives the exact ranges (example: 0664 123456). The carrier table shows which prefix blocks were allocated to which operator.
Can a mobile number in Austria be ported to another carrier?
Yes. Austria has mobile number portability, so a prefix tells you the carrier a number was originally allocated to, not necessarily the one serving it today. Only a live carrier lookup (an HLR or MNP query) answers that.
