AOK

AOK is not a single company but a network of 11 regional statutory health insurance funds across Germany, including AOK Bayern, AOK PLUS, AOK Nordost, and AOK Hessen. Members join the AOK responsible for their region, and the funds together insure more than 27 million people, making the network one of the most established pillars of the German statutory health insurance system. Each regional AOK offers the statutory benefits required by law and, in many cases, additional services that go beyond the legal minimum, such as bonus programs that reward healthy activities. Services typically include branch offices, customer telephone lines, medical advice hotlines, and online member portals. Enrollment can be done online through the website of the relevant regional AOK, by phone, or in person at a branch, and some universities also work with AOK for student enrollment. For the expat and international student community, it is important to know that AOK's main websites and service lines are primarily in German, and English-language support differs from one regional AOK to another. Prospective members should check the specific regional AOK for English-speaking hotlines and documentation requirements before applying, and consider the information provided here as a starting point rather than a substitute for official guidance.
