LuxCSD - Legal Entity Identifier Service


LuxCSD has been issuing ISO 17442:2012 compliant LEIs with the prefix 2221 since September 2014 and is a GLEIF accredited LOU (Local Operating Unit) for Luxembourg and 36 other jurisdictions.

After careful strategic review of its business strategy, LuxCSD has decided to relinquish the LOU license by end Q1 2022. As such, LuxCSD will be stopping all LEI services in February 2022. Future efforts will focus on the Company’s core CSD business.

LuxCSD ceased all LEI related activities such as issue, renew, challenge and transfer LEIs on 17 February 2022.

The LEI portfolio of LuxCSD (including all previously provided documents) has been transferred to London Stock Exchange (LSEG) operating already the LuxCSD online portal on UnaVista. 

The automatic LEI transfer was completed on 23 February 2022.

The status of your LEIs remains unchanged and all common LEI activities are seamlessly provided to you as from 23 February by London Stock Exchange.

Login credentials to the UnaVista/LSEG LEI domain i.e., email address and password for the LuxCSD LEI Portal will remain the same and can be re-used to login to the LSEG/UnaVista LEI Portal.

You can access the UnaVista/LSEG LEI Domain via this link: Data Solutions (

All invoices issued by LuxCSD to clients for LEI services rendered remain valid after transfer of the LuxCSD LEI portfolio. Clients are asked to pay their outstanding amounts without delay. LuxCSD will continue to monitor outstanding payments beyond February 2022 and request settlement of open invoices in due time.
