Verification

Account Verification & KYC Guide

3666bt is committed to maintaining a secure environment for all players. Know Your Customer (KYC) verification protects you and the platform from fraud, identity theft, and unauthorized access. The process is straightforward and typically completed within 1–24 hours.

Register Your Account

Create your 3666bt account with a valid mobile number or email address. You can deposit and play immediately — full KYC is required before your first withdrawal to protect your funds.

Submit Your National ID (NID)

Upload a clear photo or scan of your Bangladesh National Identity Card (NID) — both front and back. Ensure the document is valid, unexpired, and clearly legible. Passports and driving licences are also accepted.

Proof of Address

Provide a utility bill, bank statement, or official document issued within the last 90 days showing your full name and current Bangladeshi address (Dhaka, Chittagong, Sylhet, or elsewhere).

Selfie Verification

Take a clear selfie holding your NID next to your face in good lighting. This step confirms your identity matches the document provided and is completed entirely within the 3666bt platform.

Review & Approval

Our verification team reviews submitted documents within 1–24 hours. You will receive a notification once your account is fully verified. After approval, all withdrawal methods become available with no restrictions.

Typical KYC Processing Time: 1–24 hours on business days. Submitting clear, high-resolution documents reduces review time significantly.

24/7 Customer Support — Always Here for You

Whether you have a question about a deposit, need help understanding a promotion, or want to report a technical issue, the 3666bt support team is available around the clock — including weekends and public holidays like Eid and Victory Day.

Responsible Gaming

Play Responsibly at 3666bt

3666bt is committed to providing a safe and enjoyable environment. Gambling should always be fun — never a financial burden. Our tools help you stay in control at all times.

Deposit Limits

Set daily, weekly, or monthly deposit limits on your account to manage your spending. Limits take effect immediately and can only be reduced — never increased — without a cooling-off period.

Session Time Limits

Enable session reminders so you are notified after a set period of play. Taking regular breaks helps maintain perspective and keeps gambling a leisure activity rather than a compulsion.

Self-Exclusion

If you need a break from gambling, request a self-exclusion period of 30 days, 90 days, 6 months, or permanently. Contact our support team to activate self-exclusion at any time.

18+ Age Verification

3666bt strictly enforces an 18+ age policy. All accounts undergo age verification during KYC. For players aged 18 and above only. If you suspect underage gambling, please contact our support team immediately.

Need Support with Problem Gambling?

If gambling is affecting your finances, relationships, or mental health, help is available. Reach out to our responsible gaming team at [email protected] to discuss confidential support options. You can also visit national helplines and counselling services available in Bangladesh for free, confidential assistance.
