Whistle-blower System

A report can be sent via any of the following internal channels:

E-mail: io(kwfat)volkswagen(kwfdot)de

Please bear in mind that if you send an e-mail, there is a possibility that personal and traceable data such as the IP address may indirectly be transmitted. That information could potentially provide clues as to your identity. This also applies to e-mail accounts which have been set up specifically for whistle-blowing purposes.



The following toll-free telephone number is available 24/7: +800 444 46300*.

If your local telephone provider does not support this toll-free service, for whistle-blowing purposes you can also call the following chargeable number: +49 5361 946300*.  

* NB: you may need to use an international prefix rather than the +49.

**If there occur technical problems with the availability of the hotline, please use the other listed reporting channels to report your concern to the Investigation Office.
