As a result, all letters deposited since 5.00 this morning have been destroyed. If you dropped off a letter after 5:00 today, please contact your doctor to obtain a certified copy of the concerned document. As the deadline for sending certificates of incapacity for work is important, we would ask you to send the new medical certificate to the CNS as soon as possible, with an explanation attached, if you are no longer within the deadline.
The letterbox is currently inaccessible and you cannot post letters there. We will inform you as soon as this is possible again.
In the meantime, it is preferable to send letters by post directly to CNS L-2980 Luxembourg (you do not need a stamp) or to drop them off in the letterbox of the nearest agency.
