If you have recently become a resident but have had your covid-19 vaccinations in a non-EU country, you can now have the record if these vaccinations added to your Portuguese health records and, in so doing, obtain the Certificado Digital COVID da UE.
To access the Certificado Digital COVID da UE and QR code, you must have a utente number (ie have registered with the health service in Portugal), provide your local Centro de Saude with evidence of your vaccinations, download the recently updated SNS 24 app. The Certificado Digital COVID da UE can then be downloaded from the app.
When your records have been updated a document icon will appear in the top right hand corner of the app and a new covid-19 button option will appear in your favorites.
Hope this assists,
