Change of telephone system

The telephone system at IRZ will be changed in our Bonn and Berlin offices on 23 April 2021. Please understand that we may not be available by phone or fax on that day. After the changeover, which may take all day, we will be available for you again as usual.

You are welcome to contact our staff by email (This email address is being protected from spambots. You need JavaScript enabled to view it.) or try their mobile phone numbers.
