Get an Austrian phone number for your business.

Austrian customers call an Austrian number, and that makes a difference to both response and trust. Which number you can have depends on one thing: whether you have an address in Austria. Below is what is possible either way.

The question that decides everything

Which Austrian number can your business have?

In Austria the regulator decides which Austrian number you can have. Some numbers need your business to have an address in Austria; below you can see what is possible for each number. Where the rule is not settled, we check it with you beforehand.

Do you have an address in Austria?

  • +43 800

In stock and what it costs

Numbers available today

What a number abroad costs

€49 per monthper number

The same amount in each of the fourteen countries — an Austrian number costs no more than a number at home. Including the full phone system: forwarding, IVR menu, call queue, call recording and statistics.

Just testing the market

€250 per yearprepaid

One line, one forwarding number, no features. For anyone who first wants to know whether the phone rings at all before setting up a phone system. That is less than €21 a month — under half the full rate, with exactly one thing that works: the number rings and the call reaches you.

And the call charges

Those depend on where the call goes

A call that arrives in Austria and goes on to a VoIP line in your own country costs a different amount from one to an Austrian mobile. You get that rate with your proposal; it is the one thing we cannot put on the page, because it differs per route.

Why you can get this from us

We are the operator, not the middleman

Foreign numbers can be sold in two ways: by buying them in from someone else, or by holding the license yourself. You only notice the difference when something out of the ordinary is needed — an urgent change, a non-standard routing, a question from the regulator.

  • Europe

    No resale of numbers from a supplier who buys them in from someone else. We know the rules in each country because we are subject to them ourselves.

  • The platform

    One phone system for all your numbers

    Your Austrian, UK and German numbers come in on the same routing, with the same queue and the same dashboard. No separate accounts per country.

How it works

From request to a ringing phone

  1. You tell us what you need

    Which city or which type, and whether you have an Austrian address. If you're not sure, we'll look at it with you.

  2. We check and send a quote

    Within one business day you get a proposal with the current rates and an honest answer on whether it can be done. Sometimes the answer is that an 0800 number will serve you better than a local number.

  3. The registration

    For local numbers we submit the proof of address to the regulator. That is the only part you have to wait for.

  4. Forwarding to your team

    The call arrives in Austria and lands with your team, wherever they work. The caller dials an Austrian number and never notices the difference.

Frequently asked questions

About Austrian phone numbers

We offer three main types: Local numbers (e.g., Vienna 01, Graz 0316, Salzburg 0662) for a local presence, 0720 national numbers for a nationwide presence without a specific city tie, and 0800 toll-free numbers which are free for callers. A local number requires an address in its area-code zone, and for a 0720 number we check with you before you order whether it needs an address in Austria. 0800 numbers are available with a worldwide address, making them the easiest option for businesses.

A local geographic number (like 01 for Vienna) requires an address in the number’s area-code zone. The RTR enforces this similarly to the German Bundesnetzagentur. Whether a 0720 national number needs an address in Austria, we check with you before you order. 0800 toll-free numbers are available with a worldwide address, making them the most accessible option for businesses without a physical presence in Austria.

An 0800 number allows customers to call you for free from any Austrian landline or mobile network. You, as the number owner, cover the call costs. This is widely used for customer service lines in Austria and removes any cost barrier for your callers. Note that 0800 toll-free numbers can only be dialed from within Austria — they cannot be called from abroad.

Austrian numbers start with the country code +43. A typical landline number consists of the area code followed by the subscriber number. When advertising internationally, use the format +43 1 1234567 (dropping the leading ‘0’). Domestically, it would be 01 1234567 for a Vienna number.

Virtual numbers can typically be set up within 1 business day. Once active, calls are forwarded immediately to your existing landline, mobile, or VoIP system.

Absolutely. Our Austrian virtual numbers come with a complete professional phone system. You can set up German-language text-to-speech welcome messages, call menus, call recording for quality assurance, and time-based routing, all managed from our online dashboard.

The RTR (Rundfunk und Telekom Regulierungs-GmbH) is the Austrian authority responsible for telecoms regulation, including the assignment of telephone numbers to registered providers.

Yes, CallFactory is registered with the RTR under number 468157, authorized to issue Austrian virtual phone numbers in full compliance with Austrian telecoms law.
