Why isn't my MEXC referral code working?

A MEXC referral code only takes effect when an account is first created — if you already have a MEXC account, entering a code anywhere in the app afterward changes nothing, because your referral attribution was already set (usually to no referrer) at sign-up. MEXC doesn't offer a way to change that binding retroactively through the app, so the reliable fix is opening a new account through the correct link.

Why the code field doesn't do anything after sign-up

MEXC attributes an account to a referrer once, at creation — there's no ongoing settings field where a code entered later changes who receives the referral commission. If your account already exists, with no referrer or a different one, typing a code somewhere else in the app simply isn't wired to update that binding.

The usual reasons it looks broken

You already had an account. The most common case: attribution happens once, at creation, full stop — no matter when you enter a code afterward.
You signed up through a different link before. The account may already be bound to another referrer, so a new code doesn't overwrite it.
You typed the code somewhere it isn't read. Double-check you're using the actual referral field during sign-up, not an unrelated promo or event code box.

If your account already exists

MEXC doesn't advertise a self-serve way to switch referral attribution on an existing account. The reliable path on MEXC, as on most exchanges, is opening a new account through the correct referral link so attribution is right from the first trade — see how the MEXC payback works for what that link sets.

If you're starting fresh

Create the account through the referral link before signing up, so attribution is correct from the first trade — referral code vs fee rebate platform explains why that timing matters. On loweef's MEXC partnership the current total is 55% of every trading fee, accruing daily in USDT from the first trade:

Exchange	Total rate	Welcome boost	Effective taker
AlphaX	65%	—	0.0175%
BingX	60%	70%	0.0200%
OKX	50%	60%	0.0250%
MEXC	55%	65%	0.0180%

Figures are estimates based on published rates; actual results vary with maker/taker mix, and rates can change prospectively.

Frequently asked questions

Can I add a referral code to my MEXC account after signing up without one?

Not through the app — the referral code field only reads at account creation. MEXC doesn't publish a self-serve process to rebind an existing account, so a new account through the correct link is the reliable path.

Could a typo or expired code explain it not working?

It can contribute — double-check you copied the code exactly. But the far more common cause is that the account already exists, since MEXC only reads a referral code once, during sign-up.

My MEXC account is already bound to someone else — can I still get a payback?

Attribution can only be set once per MEXC account and MEXC doesn't offer a self-serve switch. Opening a new account through a partner link is the reliable way to start generating a payback going forward.
