Changing your details

On this page, you can access the forms to notify us of:

  • a new bank account or a change of bank account
  • a change of office address
  • the end of your activity in the Grand Duchy of Luxembourg

Simply select the form corresponding to your profession or occupation to quickly and accurately update your details with the CNS.

Please note:

The request to change bank accounts must be accompanied by a bank account identification form (relevé d'identité bancaire-RIB) issued by the financial institution.

Without this document, the request cannot be processed.

Completed and signed forms should be sent in PDF format to gefo.cns@secu.lu.
Applications in JPEG and HTM formats cannot be opened and will therefore not be accepted.
