Austria Phone Number Format

Country code +43 — Complete guide to Austria phone number formats, mobile and landline structures, and area codes.

Number Format Overview

Phone numbers in Austria use the international country code +43. When dialing from outside Austria, you must include this country code before the local number.

From the United States

Dialing Tips

  • Remove the leading zero: When dialing internationally, drop the trunk prefix (usually 0) that is used for domestic calls in Austria.
  • Use the + notation: From a US mobile phone, use +43 instead of 011 43.
  • Verify the number length: Make sure you have the correct number of digits. If your call does not connect, check whether you need to add or remove an area code digit.
  • Save contacts in international format: Always store phone numbers with the full +43 prefix so they work from any country.
