Austria is a prime business destination with tons of opportunities. In 2021, Austria experienced a marginal uptick in mobile subscriptions, totaling 10.88 million, surpassing the country’s population of 8.95 million. This translates to more than one mobile phone subscription per individual.

This statistic signifies the growing potential of the Austrian population that would involve personal as well as business communications.

This also hints in a significant need for knowing and understanding the process of making calls to Austria from the US and other major economies.

Steps for Calling Austria from the US

You can call Austria from the US using the following steps:

1. US Exit Code

Start with 011 when calling from a US landline. This code tells the phone system you’re dialing internationally. Skip it, and your call goes nowhere.

Mobile phones work differently. Use the + symbol instead of 011. Your phone automatically converts + to the correct exit code. Save Austrian contacts as +43 instead of 011-43.

Most calling failures happen here. People dial 43 first, forgetting the exit code entirely.

2. Austria Country Code

After 011 (or +), type the Austria dialing code 43. Every call to Austria needs this country code, whether you’re reaching Vienna or a village with 200 people.

The 43 country code routes your call through Austrian networks. Without it, you might reach a random number in your area or get a fast busy signal.

3. City Area Code

Vienna uses 1. Graz uses 316. Salzburg uses 662. Innsbruck uses 512. Area codes in Austria range from one digit (major cities) to four digits (small towns).

Here’s the part that confuses people: drop the leading zero when calling from abroad. Austrians list Vienna numbers as 01, but you dial 43-1, not 43-01.

The system works backward from what Americans expect. Bigger cities get shorter codes. Small rural areas get longer ones like 2622 or 7242.

4. Local Phone

The subscriber number comes last. It’s six to nine digits after the area code.

Full example: To call a Vienna landline shown as 01 512 3457, dial 011-43-1-512-3457 from your landline. From mobile, dial +43-1-512-3457.

Mobile numbers work differently. They skip area codes entirely. Austrian mobile numbers start with 6 after the country code. Format looks like: 011-43-664-1234567.

Austria Phone Number Structure

The Austria phone number structure can be confusing. Below are some of the pointers you need to remember for the Austria phone number structure:

1. Total Number Length (5–13 digits)

Austrian phone numbers range from 4 to 13 digits total when you include the country code. A small emergency service might have just 4 digits. A Vienna business number with country code hits 13.

This flexibility throws Americans off. We’re used to exactly 10 digits every time. Austria doesn’t work that way.

2. Landline Format Examples

Vienna landline: +43 1 6541239:

• Country code: 43.
• Area code:1
• Subscriber: 6541239.

Graz landline: +43 316 8234567:

• Country code: 43.
• Area code: 316
• Subscriber: 8234567.

Salzburg landline: +43 662 123456:

• Country code: 43.
• Area code: 662
• Subscriber: 123456.

Notice the total digits changes depending on the city. That’s completely normal.

3. Mobile Number Format (Starts with ‘6’)

All Austrian mobile numbers begin with 6 immediately after the country code. Common prefixes: 660, 664, 676, 680, 699.

Full format: +43 6XX XXXXXXX

Example:+43 676 1234567:

• 43: Country code
• 676: Mobile network prefix (identifies carrier)
• 1234567: Unique subscriber number

Mobile numbers total 11 digits, including the country code. The 6XX prefix replaces what would be an area code for landlines.

Time Zone and Calling Schedule

Let’s look at the time zone and calling schedule of Austria:

1. Austria Time Zone (CET/CEST)

Austria operates on Central European Time, which is UTC+1 in winter. From late March through late October, they switch to Central European Summer Time, UTC+2.

The entire country uses one time zone. No regional variations as we have in the US.

2. Time Difference from the US

Austria sits 6 to 9 hours ahead of the US time zones.

When New York hits 9 AM (EST), Vienna shows 3 PM. When Chicago hits 9 AM (CST), Vienna shows 4 PM. When Denver hits 9 AM (MST), Vienna shows 5 PM. When Los Angeles hits 9 AM (PST), Vienna shows 6 PM.

These gaps shift slightly twice a year. Both the US and Austria observe daylight saving time, but they change clocks on different weekends. This creates temporary one-hour differences for a few weeks during spring and fall transitions. Always verify the current time difference during March, April, October, and November when daylight saving time changes occur.

CallHippo automatically adjusts for daylight saving time changes and displays the correct local time for your Austrian contacts. The system accounts for both US and Austrian time zone shifts, so you don’t need to manually track the differences during transition periods.

3. Best Times to Call from US Time Zones

• From Eastern Time: Call between 3 AM and 11 AM EST to reach Austrian business hours (9 AM to 5 PM Vienna time).
• From Central Time: Call between 2 AM and 10 AM CST.
• From Mountain Time: Call between 1 AM and 9 AM MST.
• From Pacific Time: Call between midnight and 8 AM PST.

CallHippo’s timezone dialing feature shows each Austrian contact’s current local time before you dial. The display updates automatically for daylight saving changes in both countries, eliminating guesswork about when to call.

Stop Guessing Austria’s Local Time

Get a CallHippo number that auto-adjusts for every daylight-saving shift, so you always call customers at the right moment.

4. Austrian Public Holidays to Avoid Calling

Austria observes 13 national holidays. Businesses close completely. Your calls go straight to voicemail.

The week between Christmas and New Year’s essentially shuts down. Even more than in the US. Plan campaigns around these dates.

Cost-Effective Ways to Call Austria

Businesses always look for ways to save money. So, I have brought some cost-effective ways for you to call Austria. Let’s look at it:

1. VoIP Services

Traditional phone carriers charge $1.50 to $3.00 per minute for calls to Austria. VoIP drops that to $0.01 to $0.10 per minute. Sometimes less.

CallHippo’s Austria virtual numbers start at $1 for a basic plan, with premium plans ranging from $16 to $45 per user monthly. The cost includes the number itself plus calling features. Compare that to AT&T charging $2.50 per minute with no features beyond basic calling.

The bigger advantage isn’t the cost per minute. It’s the Austrian caller ID. When you use an Austrian virtual number, your customer sees a local number. They answer. Traditional international calling shows your US number regardless of what you pay.

2. Prepaid Calling Cards

Prepaid calling cards advertise low per-minute rates to Austria. The upfront cost looks appealing for occasional callers.

Most cards include connection fees that add to each call. Cards typically expire after 30 to 60 days regardless of remaining balance. Some cards charge maintenance fees that reduce your available minutes over time.

For one or two personal calls, prepaid cards can work. For regular business communication, the fees and expiration dates make them less practical than monthly plans.

3. Carrier International Plans

Major phone carriers offer international calling add-ons for a monthly fee. These plans typically include a set number of minutes to certain countries at reduced rates.

International plans often cover personal lines differently from business accounts. Business users may still face higher per-minute rates even with an add-on plan. Mobile calls to Austria sometimes cost more than landline calls under the same plan.

These plans reduce costs compared to standard per-minute rates. However, your Austrian contacts still see a US number on their caller ID, which can affect answer rates

4. Pay-Per-Minute Rates

Without an international plan, standard carrier rates apply to calls to Austria. These rates vary by carrier but tend to be significantly higher than specialized calling options.

Pay-per-minute billing works for infrequent international calls. A single call to confirm a hotel reservation or contact a business partner costs relatively little.

For regular business communication with Austrian clients or customers, standard per-minute rates add up quickly. Companies making multiple calls weekly or daily typically find more economical solutions.

Tips to Avoid High Charges

As mentioned earlier, every business wants to save money. So, why not get to know some tips that will help! Below, I have mentioned some tried and tested methods that will help avoid high charges:

1. Compare International Rates Before Calling

Check rates for landlines separately from mobiles. Many providers charge different amounts depending on the type of number you’re calling.

Look at the complete cost structure before committing to a calling method. Some services advertise low per-minute rates but add connection fees or other charges that increase the actual cost.

Understanding the full pricing helps you avoid unexpected bills and choose the most economical option for your calling patterns.

2. Use Wi-Fi-Based Calling Whenever Possible

Internet-based calling services route calls through your internet connection instead of traditional phone networks. Call quality typically matches or exceeds standard phone calls while reducing costs.

Setting up calling on both Wi-Fi and mobile data creates backup connectivity. If one connection drops during a call, the service can switch to the other connection type automatically. Your conversation continues without interruption.

This approach works particularly well for international calls where cost savings are most significant.

3. Avoid Traditional Carrier Per-Minute Billing

Standard carrier international rates often include additional fees beyond the advertised per-minute cost. Connection charges, billing increments, and time-based surcharges can significantly increase what you actually pay.

Services with flat monthly rates provide more predictable costs. Your expenses remain consistent regardless of how many calls you make within the plan limits.

This predictability helps with budgeting and eliminates surprise charges on monthly bills.

Cultural Etiquette When Calling Austria

Here are some of the cultural etiquette you need to take care of when calling Austria:

1. Use of Formal Titles (Herr, Frau, Doktor)

Austrians expect formality in business. Address men as “Herr” plus surname. Women as “Frau” plus surname, regardless of marital status.

Professional titles matter intensely. Anyone with a doctorate goes by “Herr Doktor” or “Frau Doktor” before their surname. Skip this, and you’ve insulted them before the conversation starts.

Save contact names in your CRM with proper titles. “Herr Müller,” not “Stefan” or “Mr. Müller.” Use first names only after they explicitly invite you.

2. Austrian German Dialect Consideration

Austrian German differs from standard German. Different vocabulary. Different pronunciation. Austrians notice immediately when you use Berlin phrasing.

If hiring German speakers for Austrian customer support, hire Austrian natives. A Munich speaker supporting Vienna customers creates subtle friction that damages relationships.

CallHippo’s call routing assigns specific agents to specific country numbers. Your Austrian virtual number rings only your Austria-specialist team member.

3. Common Austrian Greetings

Business calls typically start with “Grüß Gott” (roughly translates to “God greet you”) in most regions. “Guten Tag” (Good day) works everywhere safely.

Avoid “Servus” on first business contact. Too casual. Save it for established relationships after multiple successful interactions.

Program your IVR greeting with appropriate German phrases. First impressions shape how Austrians view your business’s credibility.

4. Business Call Etiquette

Get to your point faster than typical American small talk, but slower than Germans expect. Austrians value efficiency but require proper pleasantries first.

Standard Call Structure:

• Proper greeting
• Identify yourself and your company
• Confirm you’re calling at a convenient time
• State your purpose clearly
• Begin substantive discussion

Never call Austrian business contacts on weekends. Don’t call after 6 PM on weekdays. Work-life boundaries are strict and respected.

Use CallHippo’s scheduling blocks to prevent your team from accidentally calling Austrian contacts outside 9 AM to 5 PM Vienna time, Monday through Friday.

5. Emergency Number in Austria (112)

112 connects to emergency services throughout the EU, including Austria. Free from any phone. Works without SIM cards. Reaches police, fire, or ambulance.

Additional Austrian Emergency Numbers:

• Police Direct: 133
• Fire Direct: 122
• Ambulance Direct: 144
• Mountain Rescue: 140

Your US team won’t dial these for business. But if you send employees to Austrian trade shows or client meetings, program these into their phones beforehand.

Conclusion

Most US businesses calling Austria treat it like dialling any other international number. Just add more digits, pay higher rates, and accept low answer rates as normal.

That approach fails because Austrian customers screen unfamiliar international calls. Your US number triggers their spam instincts. They don’t answer.

The solution combines three elements: Austrian caller ID through virtual numbers, time-zone-aware calling schedules, and CRM integration for instant customer context.

CallHippo delivers all three in one system. Setup takes under three minutes. Pick a Vienna number (area code 1) for broad market appeal. Route it to your existing phones. Turn on German IVR. Connect your CRM. Start calling.

Action Item for Today:

• Start CallHippo’s 10-day free trial. Choose an Austrian virtual number with the Vienna area code 1. Forward it to your mobile phone. Call three Austrian prospects tomorrow during their afternoon (your early morning). Track answer rates. Compare them to your current average.
• If answer rates don’t improve by at least 25%, something else is wrong beyond caller ID. But for most businesses, local presence makes the difference between voicemail and conversations.
• Get your Austria virtual number today. Test it tomorrow. Measure results by Friday.
