APO AE 09701 provides military postal service to the U.S. Embassy in Vienna, Austria, located at Boltzmanngasse 16 in the 9th district (Alsergrund) of the Austrian capital. Vienna serves as the headquarters for several major international organizations, including the United Nations (UNOV), the International Atomic Energy Agency (IAEA), and the Organization for Security and Co-operation in Europe (OSCE). The embassy is one of the largest U.S. diplomatic missions in Europe due to America's significant engagement with these multilateral institutions.
Austria is officially neutral under its constitution, a status established in 1955, but maintains close cooperation with the United States and EU member states. The embassy manages bilateral relations covering trade, counterterrorism, law enforcement cooperation, and cultural exchange. Vienna's position as a neutral meeting ground has historically made it important for diplomatic initiatives and international negotiations. The embassy coordinates with the U.S. Mission to the International Organizations in Vienna for multilateral engagement.
The embassy provides consular services for U.S. citizens and processes visa applications. American Citizen Services are available Monday through Friday from 8:00am to 11:30am by appointment. For emergencies, contact +43-1-31339-0 during business hours. Mail routes through the USPS Newark International Service Center with delivery times of 10-14 days. Personnel sending mail should use the APO address format with the recipient's name followed by APO AE 09701.
