Change of address or bank details

If you want to inform the CNS of a change of address, the request can be done per email to:, or by  mail to the "Service Coassurance et signalétique" .
Luxembourg residents do not have to declare their change of residence to the CNS. The Luxembourg commune of arrival proceeds directly to the change in the National registre of physical persons (Registre national des personnes physiques-RNPP).


A change of bank account can be done online via MyGuichet.
