Using a voucher code at bet399 unlocks extra deposit bonuses, free spins, and cashback. There are offers available for both new and existing members.
Once you're logged in to bet399, entering a code like the ones below will add the bonus directly to your account.
Whether you're a new or existing member, there's a voucher made just for you.
Vouchers and promo codes can seem complicated at first, but at bet399 the process is simple. Just enter a special code at the time of deposit or in the designated section of your account, and the bonus is added automatically — no extra forms, no hassle.
Bet399 vouchers come in several types. The first is the deposit bonus voucher – when you enter this type of code, a set percentage of your deposit amount is added as a bonus. For example, if you deposit ৳1,000 using the WELCOME100 code, you'll receive an extra ৳1,000 as a bonus, giving you a total of ৳2,000 to play with.
Free spin vouchers are another popular offer, especially among slots fans. Use code SPIN50 at bet399 to get a set number of free spins on selected slot games. Any winnings from those spins are credited to your bonus balance and can be withdrawn once the relevant conditions are met.
Cashback vouchers are among the most popular offers around. At bet399, use code CASH20 to get back up to 20% of your weekend losses. Think of it as a safety net for regular players — even if the week doesn't go your way, you can recover a portion of what you lost.
Festival vouchers are one of bet399's standout features. Special promo codes are released during Eid ul-Fitr, Eid ul-Adha, Pohela Boishakh, and Christmas — typically for a limited time and with better-than-usual benefits. Regular bet399 players look forward to these periods every year.
It's worth understanding the wagering requirement before using a voucher. Wagering refers to the total amount you need to bet before you can withdraw any winnings from your bonus. For example, if you receive a ৳500 bonus with a 10x wagering requirement, you'll need to place ৳5,000 in bets before those winnings become withdrawable. bet399's wagering requirements are reasonable compared to many other sites and are always stated clearly.
Reload bonus vouchers aren't just for new members — existing regulars benefit from them too. Use code RELOAD50 to get up to 50% bonus on your second deposit or any subsequent deposit. Since the code can be used weekly, it's a great deal for players who deposit on a regular basis.
Sports Betting vouchers are typically tied to major tournaments. During the Cricket World Cup or IPL, bet399 releases special cricket betting vouchers. These codes are designed specifically for sports bettors, as they only apply to betting on select sports.
One common mistake when using vouchers is saving a code without checking its expiry date. Every bet399 voucher has a set validity period — typically between 7 and 30 days. Once expired, the code will no longer work and the bonus cannot be claimed. It's best to use a code as soon as you receive it.
New bet399 voucher codes are typically released first on the platform's official social media channels and email newsletter. Subscribing to the newsletter during account registration means new offers are sent straight to your inbox. VIP members also receive exclusive vouchers that are not available to regular members.
One important thing to keep in mind — the same code cannot be used twice on bet399. Each code works only once per account, so attempting to reuse it won't work. That said, new codes are released regularly, so there's always another one around the corner.
Each voucher has its own terms – including an expiry date, minimum deposit, and wagering requirements. Before using one, Rules & Terms View page.
