From 3 March 2022, every person over the age of 12 is obliged to carry proof of their COVID‑19 status when entering Germany. Persons over the age of 12 must therefore have a negative test result or proof of recovery or vaccination when entering Germany. As a rule, COVID‑19 test results (antigen or PCR tests) must not be more than 48 hours old at the time of the (planned) entry. However, if entering Germany with a carrier (e.g. an airline), PCR tests may be taken a maximum of 48 hours before the (scheduled) start of the journey (e.g. departure time). But antigen tests must not be taken more than 48 hours before the (scheduled) time of arrival in Germany even if travellers are being transported by a carrier.
Travellers who are only transferring at an airport in Germany are also required to present proof of their COVID‑19 status. This applies both to non-Schengen transit from or to third countries outside the EU and to transit from or to Schengen states.
