To access your Client Reference Code, simply go to your Dashboard and click on 'Transfer' then 'Deposit' for one of the fiat currencies. When the deposit form comes up, click on 'Wire Transfer' (and/or 'e-Transfers' for Canadians) and from here, you will be able to see your account ID (Reference number) referred to as 'REFERENCE' for wire transfers or as 'Security Question' for CAD e-Transfers.
