The 399det registration process is designed to be as simple and fast as possible. We know you want to get to the games quickly, so we have kept the sign-up form short and straightforward. Here is exactly what you need to do to create your 399det account today.
All you need is a valid mobile number, a working email address, and to be at least 18 years old. That is it. No complicated identity documents are required at the registration stage — though you will need to complete a quick KYC verification before your first withdrawal, which is standard practice on all legitimate betting platforms.
One Account Per Person: Each player is allowed one 399det account only. Creating multiple accounts is a violation of our terms and will result in all accounts being suspended. If you have forgotten your login details, use the password reset option on the login page.
Tap the "Register" button in the top navigation bar or use the registration form on this page. Both take you to the same sign-up form on 399det.
Fill in your full name, mobile number (with +880 country code), email address, and date of birth. Make sure all details are accurate — they will be used for account verification and withdrawals.
Select BDT as your preferred currency if you are based in Bangladesh. Create a strong password with at least 8 characters. If you have a promo code, enter it in the promo code field to unlock additional bonuses.
Read and accept the 399det Terms and Conditions and Privacy Policy. Confirm that you are 18 or older, then click "Create My 399det Account" to submit your registration.
You will receive a one-time verification code via SMS on the mobile number you provided. Enter this code on the verification screen to confirm your account. This step takes about 30 seconds.
Once your account is verified, head to the cashier section, choose your preferred payment method, and make your first deposit. Your welcome bonus will be credited automatically. You are now ready to play on 399det.
