Mail from government offices, agencies and courts can be conveniently received in your CAYA account. Please note that some authorities use local, alternative mail carriers to deliver mail. In this case, you will need a forwarding order with the appropriate mail carrier. How can I set up a forwarding order for alternative/regional/local postal companies?
Alternatively, you can simply provide most government agencies with your CAYA mailbox address as your new correspondence address.
The vast majority of authorities in Germany accept a different address for the delivery of correspondence (What is my Postbox address?).
