Account & Registration

To register on b399, you need your full name, an active mobile number, an email address, and a strong password — that's all it takes to get started. KYC verification with your national ID will be required when you make your first withdrawal. Registration is completely free and takes just 3 minutes.

No. Each person is allowed only one account on b399. Creating multiple accounts will result in all of them being closed and your balance may be forfeited. One account gives you access to all of b399's services.

Yes. Once you verify with the OTP sent to your mobile, your account is activated instantly. You can then make a deposit and start playing right away — no manual approval required.

Only individuals aged 18 and above may register on b399. If a minor is identified during KYC verification, the account will be suspended immediately. Responsible gaming is a core principle at b399.

Yes, you can update your email, phone number, and password from your profile settings. However, your name cannot be changed after KYC verification is complete. Contact support if you need help updating your details.
Login & Security

On the login page Click "Forgot Password?" and an OTP will be sent to your registered mobile number. Use the OTP to set a new password. The whole process takes under 5 minutes.

Entering the wrong password more than five times will lock your account for 30 minutes, after which it will unlock automatically. If you need immediate access, contact support and they will assist you right away.

No, never. The b399 support team will never ask for your password, OTP, or full card number. If anyone requests this information, it is a scam. Change your password immediately and report it to b399 support.
Deposits & Payments

Log in and go to the "Deposit" menu. Choose your preferred payment method — mobile banking or direct bank transfer. Enter the amount and complete the payment following the on-screen instructions. Your balance is usually updated within 5–15 minutes.

The minimum deposit on b399 generally starts from BDT 500, though this may vary by payment method. The maximum deposit limit depends on your account tier and verification status.

b399 does not charge any deposit fees. However, your payment provider may apply a small fee for mobile banking or bank transfers. Contact your payment provider directly for exact fee details.
Withdraw

Withdrawal requests from KYC-verified accounts are typically processed within 2–24 hours. Mobile banking transfers are usually faster, while bank transfers may take a little longer.

The minimum withdrawal is generally BDT 500. The maximum depends on your account's KYC level and daily limits. Fully verified accounts have higher withdrawal limits.

Common reasons a withdrawal may be held up include: incomplete KYC verification, unmet bonus wagering requirements, detection of suspicious activity, or incorrect banking details. Contact support for a full explanation of the specific reason.

No. KYC verification is mandatory before you can make a withdrawal. Upload a photo of your national ID or passport. Once verification is complete, the withdrawal feature will be activated. This is required for security and anti-money laundering compliance.
Bonuses & Promos

Register Once completed, your welcome bonus is automatically credited to your account on your first deposit. A specific wagering requirement must be met before the bonus can be withdrawn. Details On the promotions page See.

A wagering requirement means you need to place a set number of bets before you can withdraw bonus funds. For example, a 10x wagering requirement on a BDT 100 bonus means you must place a total of BDT 1000 in bets before withdrawing.

Reload bonuses and cashback are available during specific periods and subject to certain conditions. On the promotions page Check the latest offers. VIP members receive additional benefits. Special offers are also available for regular players.
