GouvCheck – Check the authenticity of an official document
What is the purpose of GouvCheck?
GouvCheck enables you to check the authenticity of an official document issued in Luxembourg, free of charge and in real time, using a QR code embedded in the document.
How do I use the GouvCheck app?
Anyone can check the authenticity of an official document with a 
-QR code.
Verifying an official document couldn't be easier:
- Download the app with your smartphone or tablet from the Google Play Store or the Apple App Store.
- Open the app on your smartphone or tablet.
- Scan the QR code on the document that you want to authenticate.
- The application tells you whether the QR code is valid and you can check whether the data on the document match those displayed by the application.
It is therefore impossible to commit fraud by using a false QR code on the document.
Please note: GouvCheck enables you to authenticate a document, but cannot replace the document itself.
