A written request must be sent to the CNS in order to update a bank account, either by mail to the "Service Coassurance et signalétique" or via MyGuichet by following the link below.

Note

A bank identity statement (relevé d'identité bancaire RIB) issued by the financial institution must be submitted in order to update the bank account details.

The request cannot be processed without this document.

What is a certificate of banking details (relevé d'identité bancaire RIB)?

A certificate of banking details is an official document that can be issued by your bank or other financial institutions in Luxembourg or abroad.

In Luxembourg (as well as in other countries), this document exists in the form of a certificate; your bank might only issue it as a signed/stamped letter.

This document provides information on the account holder's name as well as the IBAN and BIC/SWIFT numbers of the bank account.

An account statement or a copy of your card are unfortunately not sufficient.
