Change of phone numbers

Due to a technical migration of the telecommuncation infrastructure, our phone numbers will change as of December 9.

The currently four-digit extention numbers 9xxx will change to five-digit extention numbers 99xxx – which means that a preceded 9 will be added to the direct dialing number. Mobile phone numbers are not subject to change.

You can reach our Hotline as of December 9 via +49(0)911 – 5302 – 99236.
