Belfius does not direct register shares, so you need to transfer your shares to another broker that can DRS transfer.
A popular route has been through Interactive Brokers (IBKR) as they are available internationally and can DRS transfer for a $5(US) fee.
The quickest way is to open an Interactive Broker account, buy a share, and request a DRS transfer (link to guide here). While you wait for your Computershare account to be created, you can transfer your shares from Belfius to IBKR with a Basic FOP Transfer (free), then from IBKR to Computershare via DRS transfer for a $5(US) fee.
How to Transfer:
Once your shares are settled in Belfius, you need to create a Letter of Instruction with the receiving broker (IBKR).
Login in your IBKR account, and click on “Transfer & Pay” from the top menu and select “Transfer Positions” .
