Register at 399bay in a Few Quick Steps
Creating your 399bay account takes minutes on any phone — fill in your details, verify your mobile number, and you're in. Availability depends on local law and eligible regions in Bangladesh.
How We Protect Your 399bay Account
Account security starts at the point of registration. We apply encryption to every data submission, require mobile verification before any account is active, and keep your personal details separate from your transaction records. Here are four things we do consistently to keep your account secure.
SSL Encryption
Every form submission on registration and login is encrypted end-to-end. Your mobile number, password and payment details are never transmitted in plain text.
Mobile Identity Check
OTP verification means only the owner of the registered mobile number can activate the account. No account goes live without that step completed first.
Data Separation
Your personal registration details and your payment transaction records are stored in separate systems, reducing exposure if either layer is ever queried.
Account Access Controls
You can review active sessions and log out of devices you no longer use from inside your account settings — giving you direct control over who is signed in.
What to Expect When You Register
The registration form asks for your mobile number, a password, and basic account details. Once you submit, an OTP is sent to your number — enter it to confirm your account. After that, you can set your wallet preferences and link your preferred payment method, whether that's bKash, Nagad or Rocket. Your account dashboard shows
your balance, active sessions and transaction history from the moment you log in. If anything looks unclear during the process, our support team is reachable via live chat directly from the registration page. Keep your mobile number accurate — it's the key to account recovery and future withdrawals.
-
OTP Verification Your mobile number is confirmed by a one-time code sent instantly. Enter it to activate your account and move straight to your dashboard.
-
Wallet Linking After verifying, connect your bKash, Nagad or Rocket account in the payment section so deposits and withdrawals route correctly from the start.
-
Account Security Set a strong password during registration. Your session is protected by SSL encryption and can be managed across devices without losing your wallet state.
-
Support on Hand Live chat is available from the registration page. If your OTP doesn't arrive or a form field flags an error, get help without leaving the screen.

Deposit Right After You Register
Once your account is active, your first deposit is straightforward. Open your bKash, Nagad or Rocket app, send the amount to the account number shown on the deposit screen, then confirm with your PIN. The balance appears in your 399bay wallet once the transfer is acknowledged. Upay and Bank Transfer are also listed in the cashier for those who prefer them. Minimum and maximum amounts are shown per method before you confirm — no surprises at checkout.
Help When Your Account Needs It
Most registration questions — a missed OTP, a form validation error, or a wallet mismatch — can be resolved without waiting. We keep support reachable from the same screen you're registering on, so you don't have to open a separate tab or search for a contact page. Here are the three paths available.
