MEXC Rebind Guide: Two Accounts per KYC, New-Email Route

Existing MEXC users can rebind. Within 30 days of signup and with no referrer, add the code mexc-FEEOTTER through MEXC's official self-service linking; after 30 days, register again with a new email through the dedicated link. One KYC allows up to 2 accounts, and if both are used you must close one first, which takes up to 15 business days (checked September 2026). Through Fee Otter the MEXC rebate is 60%, 3 times a typical 20% code. On 1,000 USDT of monthly fees, a typical 20% code returns 200 USDT; Fee Otter's code returns 600 USDT.

Register MEXC through our link for a fee rebate of 60% (20% auto-refunded by the exchange plus a 40% extra from Fee Otter). If you already have a MEXC account, you can rebind it to the rebate platform (Fee Otter). This guide covers how to add a code by self-service within 30 days of signup, why it can't be added after that, how existing users rebind (one KYC covers two accounts), how the rebate is calculated, and the rate table.

What do you get by registering MEXC with Fee Otter's code?

• 60% fee rebate: 20% auto-refunded by the exchange plus a 40% extra from Fee Otter.
• One dashboard: once bound, track every rebate and your available balance on the rebate platform (Fee Otter), and request withdrawals.
• Referral code mexc-FEEOTTER: the dedicated registration link has it pre-filled.

Most MEXC codes in circulation pass on only the exchange's automatic 20%; through Fee Otter the rebate is 60%, and you can see every rebate on the data platform.

How is the MEXC rebate calculated? (a reproducible example)

Formula: rebate = your monthly fees × the rebate rate.

Example: using MEXC's 0.04% perp taker rate with 2,500 USDT margin at 20x leverage, the notional is 50,000 USDT and the one-side fee is 50,000 × 0.04% = 20 USDT. At 60%, the rebate = 20 × 60% = 12 USDT (20% auto-refunded by the exchange, 40% added by Fee Otter; see the complete fee-rebate guide).

MEXC's standard perp fees are already low (maker 0.01% / taker 0.04%, read from MEXC's public API on 21 Sep 2026; promotional pairs such as BTC and ETH are currently lower, and some contracts are zero-fee); the rebate is a further layer on top.

When do you need to rebind?

MEXC lets a main account with no referrer add a referral code by self-service only within 30 days of signup; after that, or once another referrer is bound, it can't be added. If your MEXC account wasn't registered under our code, the system can't credit rebates to you, so you need to rebind.

Typical situations that call for a rebind:

• You signed up without a code, or with one that passes on only the exchange's 20% automatic rebate.
• More than 30 days have passed since signup, or another referrer is already attached, so self-service linking is closed.
• Your original referrer can no longer be reached and rebates have stopped arriving.

Before you rebind: what to prepare

• Check signup age and referrer: under 30 days, on a main account and with no referrer, use self-service linking; no new registration needed.
• Prepare a new email: one that has never been used on MEXC, for the new account.
• Count your accounts: one person can hold at most 2; if both are used, close one first (up to 15 business days) and move its assets out beforehand.
• Write down both UIDs: note the UID of the old and the new account, since binding and support checks both rely on it. If you are not sure where to find it, see what an exchange UID is and where to find it.
• Have your Fee Otter account ready: after the rebind, bind the new UID on the rebate platform so your MEXC rebates start being recorded.

How existing MEXC users rebind

First check: within 30 days of signup you can add the code yourself

If your MEXC account is less than 30 days old, is a main account and has no referrer yet, you don't need to rebind: add Fee Otter's code directly with MEXC's official self-service linking (the referrer must have signed up before you). Once linked, it can't be changed. Steps in MEXC's self-service referrer linking guide. If it has been more than 30 days, or another referrer is already bound, use the methods below.

Recommended: re-register with a different email

One MEXC KYC can register up to 2 accounts (the cap is per person; using a different ID document doesn't raise it). So just sign up again with a new email via the dedicated link (code mexc-FEEOTTER is pre-filled), then bind the new account's UID on the rebate platform.

Already have 2 accounts?

You need to close one of them; closure takes up to 15 working days, and only after it completes can the same KYC register again. You can't deposit or trade while the closure is in progress (see MEXC's account closure guide). Move your assets out before closing.

How much more do you get after rebinding?

At the standard futures taker fee of 0.04% (MEXC official fee page) and 2,500,000 USDT of monthly volume, you pay 1,000 USDT in fees a month. Here is what each option returns:

Rebate rates verified on 2026-10-07 (combined rates when bound through Fee Otter; the live platform display prevails) · Methodology

That is 4,800 USDT more per year than a typical 20% code (400 USDT more per month × 12).

On the same 1,000 USDT of monthly fees, Fee Otter's code returns 600 USDT, 3 times a typical 20% code. If you are already a VIP on an exchange and want to rebind or sign up on another one, contact support and we can help you apply for special trading perks or a higher rebate rate. To plug in your own volume, see how much fee rebate you can earn, with worked examples; if you trade in and out many times a day, read how much day traders save with a fee rebate.

How to confirm the rebind worked

1. Log in to the MEXC account that carries Fee Otter's code and copy its UID from your profile page.
2. On the rebate platform (Fee Otter), choose MEXC, paste the UID and submit.
3. Once your next trade generates a fee, the rebate record appears on the rebate platform, usually after the exchange's daily report is imported (T+1).
4. If nothing shows up after two days, send the UID to support and we will help confirm whether the rebind worked.

Common mistakes

• Dropping the "mexc-" prefix: our code is mexc-FEEOTTER, prefix included, so use the dedicated link instead of typing it.
• Re-registering with an old email: the new account needs an email never used on MEXC.
• Trying to open a third account: the cap of 2 is per person, so close one first.
• Closing an account before moving assets: you cannot deposit or trade while closure is in progress, so move assets out first.
• Forgetting to bind the UID: registering the new account but never binding its UID on the rebate platform, so no rebates are recorded.

Add-later windows and official rebind channels differ a lot between exchanges; compare them side by side in the referral-code and rebind rules by exchange.

If you do not have an account yet, follow the MEXC registration guide and sign up with Fee Otter's code. To check where the code goes and what it is worth, read the MEXC referral code guide; for how the rebate is calculated and what it pays per month, see the MEXC fee rebate guide. After the rebind, bind your UID on the rebate platform and your next trade starts earning.

FAQ

Can I add a MEXC referral code after signing up?

Within 30 days of signup, yes, if it's a main account with no referrer yet: add Fee Otter's code with MEXC's official self-service linking. Once linked it can't be changed. After 30 days you can't, so use the rebind method above (re-register with a new email).

How much is the MEXC fee rebate?

60%: 20% auto-refunded by the exchange plus a 40% extra from Fee Otter.

How many MEXC accounts can one KYC open?

Up to two, counted per person; a different ID document doesn't raise the cap. If you haven't used both yet, re-register with a new email through the dedicated link (code mexc-FEEOTTER) to rebind.

What if both accounts are already used?

Close one of them, wait for the closure to finish (up to 15 working days), then register again via the dedicated link. Move your assets out before closing.

I already have a MEXC account. Can I rebind?

Yes. If your account is less than 30 days old, first try adding the code with MEXC's official self-service linking; otherwise, the most recommended way is to re-register with a new email via the dedicated link, check that the referral field is pre-filled, and bind the new UID on the rebate platform.

How is MEXC's rebate different from a KOL code?

Most codes pass on only the exchange's automatic 20%; through Fee Otter the rebate is 60%, and every rebate is visible on one dashboard, with withdrawals on request.

After rebinding, when do rebates start?

Once the rebind is done, the fees you generate afterwards start accruing rebates, which you can track on the rebate platform (Fee Otter); see how the rebate is settled.

How do I confirm a MEXC rebind worked?

Once you bind the new account's UID on the rebate platform, the rebind has worked when your next trade's rebate appears in the records, usually after the exchange's daily report is imported (T+1). If nothing shows after two days, send the UID to support.
