OKBK FAQ — Your questions, our answers

To update your personal information, log in to your OKBK account and go to Settings > Profile section. Most information there can be updated by you directly.

Phone number change: An OTP will be sent to the new number for verification. A confirmation code may also be sent to the old number as a security measure. If the old number is no longer active, you can verify your identity through support and request the change.

Change Name: Name changes are restricted because your name must match your KYC verification documents. If there's a typo from registration or a correction is needed, submit a request to Support along with a scan of your National ID — corrections are typically processed within 24 hours.

Change Email: You can change your email by having a verification link sent to the new address from Profile Settings.

Keep in mind — once KYC is completed, changing your name becomes difficult. It's best to enter your details accurately right from the start when registering.

Signing up with OKBK is straightforward and only requires a few basic details. A national ID is not needed at the time of registration.

What you need to register:

• Full name (as it appears on your national ID)
• An active mobile number (for OTP verification)
• Email Address
• Date of birth (must be 18 or older)
• Password (minimum 8 characters)
• Preferred currency (BDT is recommended)

When is a National ID required?

KYC verification must be completed before your first large withdrawal. Typically, if you want to withdraw more than ৳10,000 for the first time, you'll need to upload a photo of your national ID or passport. Smaller withdrawals can be processed without KYC.

Completing KYC in advance means no delays when you request a withdrawal later. You can upload your KYC documents from Account Settings at any time after registering.

Odds tell you both the likelihood of an outcome and how much you'll win — two things in one. OKBK displays odds in three different formats.

1. Decimal odds (simplest) — e.g.: 1.85

This is OKBK's default format and the easiest to understand. To calculate your total return: Stake × Odds = Total Return

• Example: You bet ৳100 at odds of 1.85 — if you win, you get ৳100 × 1.85 = ৳185 (Profit: ৳85).
• Odds of 2.00 means double your money — win a ৳100 bet and get back ৳200.
• Odds of 1.50 means lower risk, lower reward — win a ৳100 bet and get back ৳150.

2. Fractional odds — e.g.: 4/5 or 5/2

The first number is the profit; the second is the stake.

• 4/5 means a ৳5 bet returns ৳4 profit — total return ৳9.
• 5/2 means a ৳2 bet wins ৳5 profit — total return ৳7.

3. American Odds — e.g., +150 or -120

• Positive (+150): ৳150 profit on a ৳100 bet.
• Negative (-120): Bet ৳150 to win ৳100 profit.

You can change the odds format in OKBK settings. For Bangladeshi users, decimal format is the easiest to follow. Your potential winnings are displayed on screen before you place a bet — so no manual calculation needed.
