How the LinkAja Verify Process Works
The LinkAja verify path on kopi4 runs through your registered mobile number. Start by opening the cashier tab and selecting LinkAja as your method — you'll be prompted to enter the phone number tied to your LinkAja wallet. A one-time PIN is sent to that number; enter it in the confirmation field within the allowed window. Once the PIN clears, your LinkAja
account is linked to your kopi4 profile. From that point, deposits route directly through the wallet without re-entering credentials each time. Players in Medan who follow these steps typically move from cashier to lobby without leaving the page. If the PIN window expires, the cashier will offer a resend option — wait a few seconds before requesting it again.
