Crypto Exchange Invitation Codes Tested 2026: 263 Codes Found Online at 8 Exchanges, and Nearly Half Give No Fee Rebate at All

Codes that all go by “invitation code” can give anything from 0% to the exchange’s cap as a fee rebate; it all depends on what the inviter set. From 31 October to 4 November 2026, I took 263 invitation codes found online for 7 exchanges and checked each one on the exchange’s official sign-up page or official data: 123 (about 47%) gave no fee rebate at all. OKX, Binance and MEXC all have an official cap of 20%, and of the 45 codes advertised online above 20%, not one actually exceeded it. Bitget’s sign-up page doesn’t show a rate; of the 36 pages I checked, 9 advertised more than the official cap, and none could show official proof.

This post is the summary table for all 8: each exchange’s official cap, what I found, the patterns that show up across exchanges, and how to check a code yourself before signing up. Each exchange’s detailed rules and sign-up steps are in its own invitation code post.

Exchange invitation code summary: official caps at 8 exchanges vs the rates I found

“No rebate at all” counts codes the official page showed at 0% or with no fee rebate text. It leaves out codes that couldn’t be found (1 each at OKX, Binance, MEXC and Bybit). For KuCoin only partner codes are counted, since regular users’ codes show no rate before sign-up.

5 patterns across the 8 exchanges

1. No figure above the official cap ever appeared. OKX, Binance and MEXC all state in their official guides that the invitee gets at most 20%. Across the three, the 45 codes advertised online above 20% showed at most 20% on the official pages, and 5 at Binance and 4 at OKX showed 0%. BingX’s cap is 45%, and the 4 codes advertised at 45% or 50% all showed 0%. Any amount above the cap, if it exists at all, can only be something the website itself promises to pay. It doesn’t come from the exchange.

2. Figures that look high are mostly stacked. Binance’s 40% is often 20% plus the 25% off for paying fees with BNB. OKX’s “up to 52%” adds OKB deductions and VIP tiers to the code, but OKX’s trading fee FAQ says OKB deductions are not currently offered. Bybit’s “up to 58%” adds the MNT deduction. You get these discounts without any invitation code, so they are not extra from the code.

3. The most copied codes don’t necessarily give a rebate. The most cited LBank code, which appears on many English pages, is advertised as “up to 50%” and shows 0% on the sign-up page. A Bybit code advertised as a “50% permanent rebate” actually gives 20%. A code being copied onto many pages doesn’t mean anyone has checked it.

4. Few pages can show proof from the official page. None of the 9 OKX pages advertising more than 20% included a screenshot of OKX’s sign-up page. Of 54 Binance pages, only 1 had a recent screenshot of the sign-up page. Of 36 Bitget pages, none showed official proof of the rate. Where pages did include screenshots, the rates mostly matched the official pages.

5. “Permanent”, “for life” and “the highest anywhere” are everywhere, but the rules don’t back them up. None of OKX’s, Binance’s or LBank’s official rules guarantee a rate for life, and pages whose codes actually give 0% or 5% use the same words. The inviter sets the rate, and the inviter can change it.

Check it yourself before signing up: where to look at each exchange

Most exchanges show the code’s rate on the sign-up page, but only when you open it through the code’s dedicated address. If you type the code yourself on the regular sign-up page, you usually won’t see the rate. Make sure the address is on the exchange’s official domain.

This is how the pages looked from 31 October to 4 November. The exchanges haven’t officially explained these displays, and they may change with a redesign. If you can’t see a rate and the inviter can’t show a screenshot, treat it as 0%.

How I checked

• Finding codes: I searched for “{exchange} invitation code”, “referral code”, “rebate” and similar terms in Traditional Chinese, Simplified Chinese and English, and noted the codes and claimed rates from the first few pages of results.
• Checking rates: I opened each code at the official address in the table above, or checked the official data behind the exchange’s sign-up page (Binance, KuCoin), and recorded the rate shown. I didn’t rely on the pages’ own claims or screenshots.
• No names: neither the article nor the comparison images say which website or creator a code came from, and other people’s codes are hidden in the images.
• Ongoing checks: the comparison images at the top of the article are in a daily check. If the rates haven’t changed, the verified date in the caption is updated; if they have, the image is retaken. Comparison screenshots that can’t be checked automatically carry only the date they were taken, and I review them by hand every month.
• Limits: these are results from particular days, and codes found online can change their rates at any time. Some exchanges show different pages by region, so what you see may differ from what I saw.

Already signed up without the rebate?

At most exchanges you can’t change the code after signing up, and where you can add one, there are time limits and conditions: Binance within 30 days of registration and before any deposit or trade, Bybit within 14 days and only for affiliate codes. Each exchange’s deadline and conditions are in Deadlines for adding an invitation code after sign-up.

OKX, Binance and Bybit also have official ways to switch or re-bind an inviter, with stricter conditions: see OKX: changing your invitation code, Binance: re-binding an invitation code and Bybit: changing your invitation code.
