How to Register on OKX Mobile and Enter Referral Code 31999414
Step 1: Download the Official OKX App from a Trusted SourceBefore anything else, you must avoid fake apps and phishing sites. Open your phone's official app store (Apple App Store or Google Play) and search for "OKX" or "OKX – Crypto Exchange". Verify the developer is OKX with a large download count and high rating. Alternatively, use the official website link provided in the CTA below to get the correct download page. Never download APK files from random forums or Telegram groups, as fake wallets are a common way hackers steal crypto.
- Open the app store on your mobile device.
- Search for "OKX" and check the developer name carefully.
- Tap Install and wait for the app to download.
- Do not proceed with any SMS link you did not request yourself.
Open the OKX app and tap Sign Up. You can register with your phone number or email address, but phone number is recommended for faster verification and account recovery. On the registration form, look for the field labelled Referral Code or Invitation Code. It may be collapsed under an "Optional" link or shown as a separate box. You must enter the code 31999414 exactly before continuing. If you skip this step, you cannot retroactively apply the fee discount or blind box eligibility for the same account.
- Tap Sign Up and choose your country/region code.
- Enter your mobile number or email, then create a strong password.
- Find the Referral Code field and type 31999414 without spaces.
- Complete the captcha or drag verification.
- Tap Create Account and enter the SMS or email verification code.
Pro tip: If you do not see the referral code field during the first step, go back and choose "Sign up with phone" instead of a social login. Social logins often skip referral code input entirely, losing your reward.
OKX requires identity verification before you can deposit, trade, or claim any promotional rewards. Tap the account icon, then go to Verification or Identity Verification. Complete at least Level 2 (basic KYC) by uploading a clear photo of your government-issued ID (passport, driver's license, or national ID) and performing a facial scan. The process usually takes 5–15 minutes for automatic approval.
- Navigate to Account → Verification.
- Select your country and document type.
- Take photos of the front and back of your ID as instructed.
- Complete the liveness check by following the on-screen face movements.
- Wait for the confirmation email or in-app notification.
Without Level 2 KYC, the blind box reward will not be credited, and fiat deposit or withdrawal will be blocked. Do not skip this step even if you only plan to claim the reward.
The 2026 blind box promotion normally requires a first deposit of at least 50 USDT equivalent in eligible assets. You can deposit crypto from another wallet or buy crypto directly with fiat using OKX's on-ramp service. After your deposit is confirmed on-chain, go to the Reward Center or Promotions tab in the app. Look for a banner like "New User Blind Box" or "Referral Reward". Tap it, and your blind box will be ready to open.
- Go to Assets → Deposit and choose a supported cryptocurrency (USDT, BTC, ETH, etc.).
- Copy the deposit address and send the required minimum amount.
- Wait for the network confirmation (usually 1–30 minutes depending on blockchain).
- Open the app, go to Reward Center, and locate the blind box section.
- Tap "Open Box" to reveal your random reward. Rewards may include crypto bonuses, fee rebate vouchers, or other prizes.
Note: Some blind boxes require a small trading volume within 7 days after claiming. Read the promotion terms carefully inside the OKX app to avoid losing your reward.
After entering the referral code 31999414, your account is permanently tagged for a 20% trading fee rebate on spot and futures trading according to OKX's standard referral terms. To check that your discount is active, go to Account → Fee Rate. You should see a note indicating your referral discount or a reduced fee tier. If you do not see it, contact OKX support with your UID and mention the referral code. The blind box reward will appear in the Reward Center under "My Rewards".
- Go to Profile → Fee Rate and confirm your maker/taker fees reflect the discount.
- Check the Reward Center for active vouchers or blind box assets.
- If the reward is not credited after 24 hours, submit a support ticket with your UID.
- Never share your login credentials with anyone, even if they claim to be OKX support.

Why the Referral Code 31999414 Saves You Real Money
Most traders ignore referral codes because the savings seem tiny at first glance. But crypto trading fees are charged on every order you place, both when buying and selling. On OKX, the standard spot taker fee is around 0.1%, and futures taker fee can be 0.05% or higher depending on tier. A 20% rebate on those fees means you keep 20% more of your profits on every single trade.
Consider a trader with a modest $50,000 monthly spot trading volume. At a 0.1% taker fee, they would pay $50 each way, so $100 round trip. With the referral code 31999414, the 20% rebate saves $20 per month on that volume. Over one year, that is $240 saved. If you trade futures with higher volume, say $200,000 monthly, the savings multiply to over $1,000 per year. That money goes directly back into your trading account instead of exchange fees.
Beyond the fee rebate, the blind box reward can contain crypto airdrops, fee discount vouchers, or even small amounts of Bitcoin or Ethereum at 2026 market prices. While the reward is random, entering the correct referral code during registration is the only way to unlock it. The process is front-loaded: spend an extra 30 seconds during sign-up, and you benefit for the entire lifetime of the account.
A Quick Case Breakdown: How to Maximize the Reward
Suppose you sign up with the code 31999414, complete Level 2 KYC in 10 minutes, deposit 100 USDT, and open your blind box to receive a $10 USDT bonus plus a 30-day 50% trading fee discount voucher. You then make a few spot trades totalling $2,000 in volume. The fee savings from the voucher plus the lifetime 20% rebate from the referral code generate immediate, measurable value. In this scenario, the $10 bonus is pure profit, and the fee discounts reduce your cost basis on every future trade. The key is to complete all required steps within the promotion window and take a screenshot of the terms for your records.
Critical Risk Warnings and Smart Trading Practices
Risk Warning 1: Crypto Markets Are Extremely Volatile
Prices of Bitcoin, Ethereum, and all altcoins can swing double digits in hours. Never deposit money you cannot afford to lose. The blind box reward is a promotional bonus, not a guaranteed profit. Do not chase losses or use leverage you do not understand.
Risk Warning 2: Blind Box and Referral Promotions Have Terms
OKX may require a minimum deposit, specific trading volume, or a holding period before you can withdraw the blind box reward. Read the full terms inside the app before depositing. If you do not meet the requirements within the promotional window, the reward may be forfeited. The referral fee rebate itself is usually permanent, but the blind box is a limited-time event.
Risk Warning 3: Security and Regulatory Risks Are Real
Always use the official OKX app and enable two-factor authentication (2FA). Never share your password, 2FA code, or private keys with anyone. Regulatory changes in your country can affect deposit, withdrawal, or trading services. OKX may suspend services in certain jurisdictions.
