Process to obtain an LEI  code

LEI Registration with LuxCSD is a straightforward process:

  1. Please send an email to with your request to obtain an LEI code. LuxCSD LEI Service will send you a document to be completed for individual or bulk requests.
  2. Please complete the document and send it back to

  4. Payment will only be requested once the LEI has been assigned.

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 prior the expiration date.

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 from registrants or third parties for LuxCSD-managed LEIs can be sent to LuxCSD via

To support high standards of data quality worldwide, GLEIF provides a centralised challenge facility. For more information visit the GLEIF website.
