Where to find the referral code
When opening an account late at night, the first question is, where is the code? If a familiar person has used it before, start there.
Message or Group Note
Many Dhaka users keep the code in group chats; later, when opened, essential account details are at hand.
Next to Login Page
Sometimes the code is seen near the login page; opening the ck4 Login page also clears the account path.
If you don't have a code, first match it with someone you know, then the next step becomes much smoother.
