MEXC Rebind Guide: Two Accounts per KYC, New-Email Route
One MEXC KYC covers two accounts, so existing users rebind by registering again with a new email under mexc-NOVA888. Both used? Close one and wait 15 days.
Register MEXC with referral code mexc-NOVA888 for a fee rebate of up to 60% (20% auto-refunded by the exchange plus a tier-based extra of up to 40%) — and the no-threshold Lv.1 already pays 50%. If you already have a MEXC account, you can rebind it to the rebate platform (Quant Nova). This guide covers why a code can't be added after signup, how existing users rebind (one KYC covers two accounts), how the rebate is calculated, and the tier table.
What do you get by registering MEXC with mexc-NOVA888?
Up to 60% fee rebate: 20% auto-refunded by the exchange plus a tier-based extra of up to 40%; Lv.1 pays 50% with no threshold to climb.
A one-stop rebate data platform: once bound, track every rebate, your balance, tier and XP on the rebate platform (Quant Nova), and request withdrawals.
Most MEXC codes in circulation pass on only the exchange's automatic 20%; through Quant Nova the rebate reaches up to 60% by tier, and you can see every rebate and tier on the data platform.
How is the MEXC rebate calculated? (a reproducible example)
Formula: rebate = your monthly fees × the rebate rate for your tier.
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 the top tier (60%), the rebate = 20 × 60% = 12 USDT (20% auto-refunded by the exchange, up to 40% added by Quant Nova; see the complete fee-rebate guide).
MEXC's perp fees are already low (maker 0.01% / taker 0.04%, read from MEXC's public API on 21 Sep 2026); the rebate is a further layer on top. The same fee also counts as experience points (XP), raising your tier; the higher your tier, the higher the extra rebate.

When do you need to rebind?
MEXC only lets you enter a referral code at signup; it can't be added afterwards. If your MEXC account wasn't registered under our code, the system can't credit rebates to you — so you rebind to mexc-NOVA888.
How existing MEXC users rebind
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, confirm that mexc-NOVA888 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 and wait 15 days before the same KYC can register again. Move your assets out before closing.

If you trade at high volume, hold exchange VIP status, or run quantitative strategies, you can also apply here for an upgrade to Supernova — our highest tier, with the highest rebate.
No. MEXC only lets you enter a code at signup; it can't be added or changed afterwards. If you already have an account, use the rebind method above (re-register with a new email).
What is the maximum MEXC fee rebate?
Up to 60%: 20% auto-refunded by the exchange plus a tier-based extra of up to 40%; the no-threshold Lv.1 pays 50%. Your tier is set by the fees (XP) you accumulate, and reaching a threshold takes effect immediately.
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 and enter mexc-NOVA888 to rebind.
What if both accounts are already used?
Close one of them, wait 15 days, then register again via the dedicated link. Move your assets out before closing.
I already have a MEXC account — can I rebind?
Yes. The most recommended way is to re-register with a new email via the dedicated link, confirm mexc-NOVA888 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 Quant Nova the rebate reaches up to 60% by tier, and every rebate, tier and XP is visible on the one-stop data platform and withdrawable.
