The MEXC referral code mexc-27WIN gives a 20% discount on trading fees across spot, futures, and Prediction markets, plus welcome rewards of up to 10,000 USDT. Enter the code during sign-up; if it is missed, MEXC support can still add it within 3 days of registration. After that, the account remains without the referral discount.
How to activate the code
MEXC labels this field differently depending on where you are: "Referral Code" on the website, "Enter invitation code" inside the field itself, something slightly different again in the app. Same field either way.
Step by step:
- On MEXC, open the sign-up form by clicking "Sign up" in the top right corner.
- Register by email — with Google or Apple sign-in the referral field doesn't always appear.
- Expand the "Referral Code (Optional)" block and enter mexc-27WIN in full, prefix and hyphen included.
- Right below the field, a confirmation line appears: "Commission sharing: Spot 20.00% | Futures 20.00%". That means the code is accepted. The line names two products, but the discount covers Prediction Markets as well — that part isn't shown on the form.
- Click "Continue", create a password, and confirm your email with the code that arrives in the letter.

How to use the code's rewards
Pass basic KYC, and the following become available:
- 20% discount. MEXC's spot maker fee is already 0%, so there's nothing to discount; on the taker side, on futures, and on Prediction Markets it works at full strength. You can also enable fee payment in MX for extra savings, with the usual token-price risk attached.
- Bonus of up to 10,000 USDT. The ceiling used to be 8,000 — half the write-ups out there still quote the old number. The bonuses live in the "Rewards Center", reachable from the "Events Center" or the "10,000 USDT Bonus" widget on the home screen. One rule to know before you touch it: the bonus is claimed manually in the Rewards Hub, works only as futures margin and can't be withdrawn — and withdrawing anything from the futures account, including profit you made with it, wipes the whole bonus.
What you'll actually get:
| Stage | What it takes | Realistic reward |
| Starter tasks | deposit, first trade, setting a stop-loss | around 100 USDT in futures bonuses |
| Volume targets and weekly challenges | regular futures turnover | 50–100 USDT over an active year |
| The 10,000 USDT ceiling | sustained high volume every week | not a typical result |

"My Rewards" on my account shows 851 USDT accumulated over six years — one active account, not a typical result.
How it compares
MEXC sits right behind Bybit on the reward ceiling and matches OKX and Binance on the discount, with a spot maker fee that is already zero before any code. On paper it's the strongest package in this table; in practice the ceiling belongs to volume challenges, and the starter tasks are what most accounts actually collect.
| Condition / Exchange | MEXC | Bybit | OKX | Binance |
| Welcome rewards | up to 10,000 | up to 35,140 USDT | up to 5,000 USDT | up to 100 USDT |
| Fee discount | 20% | none | 20% | 20% |
How we check the code
Every month we run three checks:
- We log into our partner account and confirm that the code is still linked to it.
- In private mode we walk through sign-up as an ordinary user, type the code in by hand and check that the fee-sharing line appears under the field.
- The exchange periodically changes the bonus mix, so we follow the rewards section.
That way we only publish codes that actually work.
Why the discount or bonus didn't arrive
Most cases come down to one of five things.
- No confirmation line under the field. The code wasn't accepted. Check that it's entered in full, mexc-27WIN with the prefix and hyphen, and that you're registering by email.
- Signed up through Google or Apple and never saw the field. The account exists without a code, and you have 3 days to get support to attach it; the steps are in the FAQ below.
- The code is attached, but spot fees look the same. On spot the maker fee is already zero, so there's nothing to discount; the 20% shows on taker orders, futures and Prediction Markets.
- The Rewards Center is empty. Tasks open only after KYC; until then they stay locked.
- The bonus is nowhere near 10,000 USDT. The ceiling is the sum of every volume challenge. Starter tasks pay around 100 USDT, and that's what most accounts collect.
