How to Register on 399 — Step by Step

Registering on 399 is one of the simplest things you will do today. The whole process takes about three minutes if you have your mobile number and a valid email address ready. Here is exactly what happens when you register:

First, fill in the registration form at the top of this page. You will need your full name, mobile number, email address, date of birth, and a username you want to use on 399. Choose a strong password — at least eight characters with a mix of letters and numbers. If a friend referred you to 399, enter their referral code in the optional field to make sure both of you get the referral reward.

Once you submit the form, 399 will send a one-time verification code (OTP) to the mobile number you provided. Enter that code on the next screen to confirm your number is real and belongs to you. This step protects your account from the moment it is created.

After your number is verified, your 399 account is active. You can log in immediately, browse the games, and make your first deposit to claim your welcome bonus. The entire register process — from filling in the form to having a fully active account — takes under five minutes for most people.

What You Need to Register on 399

Before you start the registration form, make sure you have the following ready:

• A valid Bangladeshi mobile number — this is used for OTP verification and account recovery. bKash, Nagad, or Rocket numbers all work.
• An email address — used for account notifications and password resets. A Gmail or Yahoo address is fine.
• Your date of birth — you must be 18 years or older to register on 399. We verify this during the registration process.
• A username — this is how other players will see you on 399. Choose something you are happy with; you can only change it by contacting support.
• A strong password — do not use your phone number or birthday as your password. Use something unique to 399.

You do not need a bank account to register or play on 399. All deposits and withdrawals are handled through mobile financial services like bKash, Nagad, and Rocket, which most people in Bangladesh already use every day.

After You Register — What Happens Next

Once your 399 account is active, here is what we recommend doing in order:

• Complete your profile. Add any missing details to your account profile. A complete profile makes withdrawals faster because your identity is already on file.
• Make your first deposit. Head to the deposit section of your 399 account and choose bKash, Nagad, or Rocket. Enter the amount you want to deposit and follow the on-screen instructions. Your balance will be credited within seconds.
• Claim your welcome bonus. Your first-deposit welcome bonus is applied automatically when you make your first deposit on 399. Check the FAQ page for the current bonus amount and wagering requirements.
• Explore the games. With your balance loaded, you are ready to play. Try Fishing Yi Lu Fa, spin the reels on Treasures of Aztec, join a Lucky Bingo room, or place a bet on your favourite sport — it is all available from your 399 account.
• Download the 399 app. For the best experience on mobile, download the 399 app from the App page. It is faster, smoother, and gives you push notifications for bonuses and promotions.

Is 399 Safe to Register On?

Yes. 399 takes the security of your account and your money seriously. When you register, your personal data is encrypted and stored securely. We use OTP verification to make sure only you can access your account. Withdrawals are only processed to the mobile wallet linked to your verified account, which means nobody else can take your winnings.

399 also has a strict responsible gaming policy. You can set deposit limits, take cooling-off periods, or self-exclude at any time from your account settings. We do not want anyone to play beyond their means, and we have built the tools to make sure you stay in control. Read more on the Responsible Gaming page.

If you ever have a concern about your account security — a suspicious login, a password you want to change, or anything else — contact 399 support immediately via live chat or email. We respond quickly and take security reports seriously.

Common Questions About Registering on 399

Can I register more than one account?

No. Each person is allowed one 399 account only. Creating multiple accounts is a violation of the Terms and Conditions and may result in all accounts being permanently closed and balances forfeited. If you have forgotten your login details, use the password reset option or contact 399 support.

What if I enter the wrong mobile number during registration?

If you enter the wrong number, you will not receive the OTP and will not be able to complete registration. Go back and re-enter the correct number. If you have already submitted and are stuck, contact 399 support and we will help you correct it.

Is there a minimum age to register on 399?

Yes. You must be 18 years or older to register on 399. We verify age during registration and may request additional documentation at any time. Accounts found to belong to minors are closed immediately.

How long does registration take?

Most people complete the 399 registration process in under three minutes. The only variable is how quickly you receive and enter the OTP — usually it arrives within 30 seconds.
