We get a lot of questions about the COVID-19 proof of recovery: a travel document which shows you have recently had COVID-19. These certificates are only issued via the GGD/CoronaCheck-app.
You can only get the proof of recovery if you have had a COVID-19 test at the GGD. This means you had symptoms and tested positive at an official GGD test location. You can download the proof of recovery in the CoronaCheck-app if you tested positive at least 11 days ago.
Did you have COVID-19 symptoms and were you tested by a commercial provider (for instance via your job0? Then you can also download the proof of recovery in the CoronaCheck-app. Your test results must have been passed on to the GGD by the commercial test provider, otherwise they will not be in the national system.
You can find more information and help in downloading the proof of recovery on the website of the Dutch Government.
