2026 Step-by-Step Guide to Registering on OKX: Where to Enter Referral Code 31999414, Can You Add It After Registration, Lifetime Commission Rebate + Alipay Deposit Latest Guide

Every week I review at least three new OKX accounts, and nearly all of them have the same silent mistake: the owner skipped the referral code field. That one missed box means they permanently forfeited a lifetime 20% trading fee rebate before they even made their first deposit. If you are reading this before you register, do not make that error. Type Enter Referral Code: 31999414 into the correct slot during signup, and the rebate will stay attached to your account for spot and derivatives trading.

Referral Code 31999414 Is Not a One-Time Coupon, It Is a Cost-Structure Change

OKX uses its referral system to reward users who join through a code, but many traders misunderstand what that means. It is not a small welcome gift. The code 31999414 changes your trading fee tier from the very first order. For spot trades, the standard maker/taker fee is already competitive, but cutting that by 20% on every order for the life of the account is a structural edge. If you plan to trade monthly, the difference adds up faster than most beginners expect.

Here is a simple case breakdown. Suppose you trade $10,000 worth of Bitcoin spot every month. At a typical 0.10% taker fee, you pay $10 per side, or $20 for a full buy-and-sell round. A 20% rebate returns $4 on that single round. Over 12 months, that is $48 saved on spot alone. If you trade derivatives or rotate positions more frequently, the annual savings can reach hundreds of dollars. This is not promotional noise; it is a mathematical reduction in your transaction cost, and it only works if the code is applied before your first trade.

Registration Walkthrough: Where to Enter Referral Code 31999414

Below is the 2026 OKX signup flow. Each main step is shown in its own card. Do not skip step 2—it is the entire reason you are able to lock in the lifetime rebate.

1. 1
   Open the Official OKX Signup Page

   Use only the official OKX website or app. The registration page asks for your email or phone number and a password. On some mobile versions, the referral code field is collapsed by default. Tap “Referral code,” “Invitation code,” or “Friend code” to expand it.

2. 2
   Enter the Code 31999414 Exactly

   Type 31999414 into the referral code field. Do not add spaces, hyphens, or letters. The field may be labeled “Referral code,” “Invitation code,” or “Friend code.” Before continuing, double-check the numbers. OKX binds the rebate at this exact moment.

3. 3
   Complete Email or Phone Verification

   After you submit the registration form, OKX sends a verification code to your email or phone. Enter it promptly. The lifetime fee rebate is attached after the account is fully created, but only if the referral code was present in the signup form.

4. 4
   Finish Identity Verification and Secure Your Account

   Complete KYC identity verification as soon as possible. Most 2026 OKX services, including Alipay P2P deposits, require Level 2 identity verification. Enable two-factor authentication before you fund the account. The 20% fee rebate is already tied to your account, but you need active verification to trade and deposit.

Can You Add Referral Code 31999414 After Registration?

The short answer is: often no, but there is a narrow exception. OKX binds referral codes at account creation. After registration, the ability to retroactively enter 31999414 is limited. Some users may see a “Referral code” or “My Referral” section under their profile if the account is brand new and has never traded. However, this is not standard across every region, and it should never be relied on as a replacement for entering the code during signup.

If you have already completed registration but have not deposited or traded, you can contact OKX support immediately and ask whether the code 31999414 can be reviewed on a case-by-case basis. If you have already made a deposit or executed a trade, the code cannot be retroactively applied to that account for lifetime rebate purposes. The cleanest solution is to create a new account using the official OKX link and enter the code before making any deposit or trade.

Alipay Deposit Guide: 2026 Latest Flow

After your account is registered with referral code 31999414 and verified, you can move to funding. Alipay is one of the most common CNY deposit methods on OKX’s P2P marketplace. The flow is fast, but you must follow the platform rules exactly to avoid payment delays or order freezes.

1. 1
   Complete Level 2 Identity Verification

   Go to your OKX profile and upload the required identification documents. Without Level 2 verification, you will not be able to access the CNY P2P Alipay trading desk. Ensure your name on OKX matches your Alipay real name.

2. 2
   Open Buy Crypto and Select P2P or Express

   From the OKX home screen, tap “Buy Crypto” and choose “P2P Trading” or “Express.” Set the currency to CNY and filter the payment method by Alipay. Look for merchants with a high completion rate and a recent trade volume.

3. 3
   Enter the CNY Amount and Confirm the Order

   Enter how much CNY you want to spend or how much USDT you want to receive. Read the merchant’s terms carefully. Some merchants have a minimum trade size or time window. Once you confirm, the order timer starts.

4. 4
   Pay the Exact Amount via Alipay

   Use your own verified Alipay account to transfer the exact amount shown in the order. Do not include any crypto-related words in the transfer note. Keep a screenshot of the payment confirmation and your Alipay transaction ID until the seller releases your USDT.

5. 5
   Return to OKX and Click “I Have Paid”

   After your Alipay transfer is successful, go back to OKX and tap “I have paid” or “Confirm payment.” The seller will verify the payment and release the USDT to your OKX funding account. This usually takes a few minutes but can take longer during peak times.

6. 6
   Move Funds to Trading Account

   Once the USDT is in your Funding account, transfer it to your Trading account if you plan to spot or derivatives trade. The lifetime 20% fee rebate tied to code 31999414 will automatically apply to eligible trading fees.
