How to Call Austria from US

Austria Area Codes (Landlines)

Below is an extensive list of Austrian landline area codes (Ortskennzahl), including major cities and regions. When calling from the USA, dial 011 + 43 + Area Code + Local Number. Remember to drop the leading '0' from the Austrian area code.

Note: This list is comprehensive but may not include every small locality's specific code variation. Major cities and districts are covered.

Mobile Phone Networks in Austria

Austrian mobile numbers typically start with a '6' after the country code 43 (e.g., 43 6xx). When calling from the USA, the format is 011 + 43 + Mobile Prefix (starts with 6) + Subscriber Number. The total length is usually 10 or 11 digits after the country code 43.

The main mobile operators in Austria are A1 Telekom Austria, Magenta Telekom (formerly T-Mobile Austria), and Hutchison Drei Austria. Mobile Number Portability (MNP) is available, meaning the prefix doesn't always guarantee the current operator.

Note: This list shows common prefixes and original assignments. Due to number portability, a number starting with '664' might now be served by Magenta or Drei.

Time Difference in Austria

Austria is in the Central European Time Zone (CET). It observes Daylight Saving Time (DST), known as Central European Summer Time (CEST).

• Standard Time: CET, which is UTC+1. Typically runs from the last Sunday in October to the last Sunday in March.
• Daylight Saving Time: CEST, which is UTC+2. Typically runs from the last Sunday in March to the last Sunday in October.

The time difference between Austria and the United States (USA) varies depending on the time of year due to both locations observing DST (though on slightly different schedules):

US Eastern Time (ET): Austria is 6 hours ahead of EST (US Standard Time) and 6 hours ahead of EDT (US DST). (When US is on EDT and Austria is on CEST, the difference remains 6 hours).
(Example: 9 AM EST is 3 PM CET; 9 AM EDT is 3 PM CEST)
US Central Time (CT): Austria is 7 hours ahead of CST and 7 hours ahead of CDT.
US Mountain Time (MT): Austria is 8 hours ahead of MST and 8 hours ahead of MDT.
US Pacific Time (PT): Austria is 9 hours ahead of PST and 9 hours ahead of PDT.
(Example: 9 AM PST is 6 PM CET; 9 AM PDT is 6 PM CEST)

Important: Double-check the current time difference before placing your call, especially during the DST transition periods in March/April and October/November, as the US and Europe switch on different dates.

Austria's Phone System

Austria has a highly developed and reliable telecommunications infrastructure. The landline network, historically dominated by A1 Telekom Austria, remains robust, although mobile usage is extremely prevalent. The mobile market is competitive with three major network operators (A1, Magenta, Drei) and several Mobile Virtual Network Operators (MVNOs) offering extensive 4G/LTE coverage across the country, with 5G deployment rapidly expanding, particularly in urban centers and along transport routes. Broadband internet access is widespread, facilitating the common use of VoIP services and messaging apps for communication.

Best Times to Call Austria

Considering the time difference (Austria is 6-9 hours ahead of the US), planning your call is advisable.

Standard Austrian business hours are generally Monday to Friday, from around 8:00 AM or 9:00 AM to 5:00 PM or 6:00 PM CET/CEST (UTC+1/+2).

The most convenient time to call Austria from the USA is typically during the US morning:

• 9:00 AM to 12:00 PM US Eastern Time (ET) corresponds to 3:00 PM to 6:00 PM in Austria. This catches the Austrian afternoon business hours.
• 8:00 AM US Pacific Time (PT) corresponds to 5:00 PM in Austria, which might be suitable for reaching someone just before or after their workday ends.

Avoid calling too early in the US morning, as it will be the middle of the night in Austria. Always confirm the current time difference before calling.
