Renew or challenge an existing LEI code

The renewal process enables the registrant to modify the LEI record and to extend the validity “Next Renewal Date” of an existing LEI. In accordance with the LEI  Regulatory Oversight Committee (ROC) and many regulations, every LEI should be renewed at least once a year. Renewal reminders will be sent by email to the registrant 60 days, 30 days and 15 days prior to the expiration date and the last reminder one day after the expiration date. A detailed description of the renewal process using the LuxCSD Online Portal can be found in the LEI Services Guide that is attached below.

The challenge process enables the registrant or third party to request a correction or modification of the LEI record, subject to validation. A challenge will not extend the validity of the LEI. Challenges are free of charge and can be used, for example in the case the legal entity changes their legal name or address as long as the change can be confirmed. Challenges can also be raised if there are any questions about the uniqueness of an LEI code or the accuracy of the reference data. Challenges of own or third party LEIs of LuxCSD LEI portal registrants can be done directly via the portal. For further details of the challenge process on the LuxCSD LEI platform please consult the LEI Services Guide that is attached below.

Another possibility to challenge LEI reference data managed by LuxCSD or another LEI issuer is offered by GLEIF’s centralised challenge facility. For more information visit the GLEIF website.
