Why can't I use my NRIC/IC/Passport/FIN number? It says it's already in use.

This happens when your NRIC/IC/Passport/FIN number is already registered with another DA account. You likely created a DA account in the past using a different email address and added your NRIC/IC/Passport/FIN number to that older account.

You can either use this other older account of yours, or if you prefer to use this new account, please contact our Customer Support here for assistance, as this situation requires special handling.
