Updated
On November 2, 2026, I took 367 public referral codes for 14 exchanges, all of them findable online, and entered them one by one on each exchange’s official sign-up page to see how much rebate each code actually gives the person who signs up. At the 10 exchanges where the rate can be checked, 288 codes returned a rate, and 154 of them give 0%. Of the 207 codes that state a specific rate and could be checked, 144 actually give less than they claim. At the 7 exchanges that publish a cap, not a single code went above the official cap.

Compare 17 exchange referral codes →Key points
Binance, OKX, Gate, MEXC, BingX, KuCoin and HTX all publish a cap on referral code rebates, and none of the codes I checked gives more than that cap. Of the 62 codes that claim more than the cap, 56 had a checkable rate: 31 of those are 0% and 18 are exactly at the cap.
Of the 58 codes whose stated rate equals the official cap (for example the “20%” at Binance, OKX and MEXC), 47 could be checked, and 24 of those give less, 19 of them 0%.
Of the 52 codes labeled “lifetime” or “permanent”, 42 had a checkable rate, and 19 of those are 0%.
The official sign-up pages of Bitget, Pionex, WEEX and BTCC don’t show any referral code’s rate, so the numbers posted online can’t be verified on an official page before you sign up.
At the 10 exchanges where the rate can be checked, no public referral code gives a higher spot or futures rebate than this site’s code; this site’s code is basically the highest among public codes at all 10, and at 6 of them it gives the official cap.
How was this test done?
Collecting the codes: I searched in Traditional Chinese, Simplified Chinese, English, Spanish, Vietnamese and Indonesian for terms like the exchange name plus “referral code”, “invite code” or “rebate”, read roughly the top 10 organic results for each query, skipped the exchanges’ own websites and this site, and recorded each code, the rate stated on the page and the page’s language. Codes for other exchanges on the same page weren’t counted toward the exchange I was checking. This site’s own codes aren’t among the 367 either; they served only as a comparison.
Checking the rates: I went only by the exchanges’ own pages. I opened the official sign-up page with each code filled in, in a browser, recorded the rate the page showed, and also read the referral code data the sign-up page loads from the exchange, such as the invite information Binance’s sign-up page fetches. The sign-up pages of Gate, XT.COM and Ourbit print the rate only in certain cases; for codes whose rate isn’t visible on the page, I used the same official data the sign-up page had loaded. For most exchanges I also tried codes I made up as controls, to see how the page displays a code that doesn’t exist.
- The results are the rates as of November 2, 2026. If a referrer changes their settings or an exchange changes its rules, the results change too.
- Some sign-up pages show only one market: HTX’s Traditional and Simplified Chinese sign-up pages show the spot rate, and LBank’s shows the futures rate. The “best public code” column below takes the higher of the spot and futures rates.
- Some pages have been deleted or won’t open; for those codes, the claimed rate comes from the page title or the search result snippet.
- 0% means the code passes no rebate on to the invitee. Sign-up rewards are set separately by the exchange and have nothing to do with the rebate rate.
- This report doesn’t name any other referral codes, websites or authors; it lists only statistics and anonymous examples.
What did the test find at the 10 exchanges where the rate can be checked?
“With a rebate” means a code with a rate above 0%. “Invalid or no rate shown” covers codes the exchange reported as nonexistent and cases where the sign-up page doesn’t show a rate: some OKX promotion pages show only a new-user reward, KuCoin doesn’t show the rate for regular users’ codes, and 2 of the Binance codes are CPA sign-up reward links.
| Exchange | Codes checked | With a rebate | 0% | Invalid or no rate shown | Best public code | This site’s code |
|---|---|---|---|---|---|---|
| Binance | 51 | 29 | 20 | 2 | 20% | 20% |
| OKX | 41 | 15 | 0 | 26 | 20% | 20% |
| Gate | 25 | 15 | 9 | 1 | 20% | 20% |
| MEXC | 42 | 13 | 28 | 1 | 20% | 20% |
| BingX | 30 | 9 | 20 | 1 | 25% | 45% |
| KuCoin | 27 | 5 | 16 | 6 | 25% | 60% |
| HTX | 22 | 8 | 14 | 0 | 30% (spot) | 30% |
| XT.COM | 33 | 22 | 11 | 0 | Futures 60%, spot 35% | Futures 60%, Spot 35% |
| LBank | 30 | 11 | 19 | 0 | Futures 50% | Futures 50%, Spot 30% |
| Ourbit | 24 | 7 | 17 | 0 | Spot and futures 50% | 50% |
| Total | 325 | 134 | 154 | 37 | — | — |
How much rebate the referral codes I checked actually give, by exchange
Each bar is every code I checked for that exchange; the number on the right is how many give 0%
- Gives the official cap
- With a rebate

- Invalid or no rate shown
- Binance (51 codes)0%: 20
- OKX (41 codes)0%: 0
- Gate (25 codes)0%: 9
- MEXC (42 codes)0%: 28
- BingX (30 codes)0%: 20

- HTX (22 codes)0%: 14
- XT.COM (33 codes)0%: 11
- LBank (30 codes)0%: 19
- Ourbit (24 codes)0%: 17
At all 10 of these exchanges, this site’s code is the highest among public codes or tied with the highest. At Binance, OKX, Gate and MEXC, this site’s code gives the official cap, the same as the highest value I found. At BingX and KuCoin it also gives the official cap, while the best public code I found gives only 25%. At HTX, XT.COM, LBank and Ourbit, one to four public codes match this site’s code on spot or futures, and none is higher.

Which 4 exchanges don’t show a referral code’s rate before you sign up?
The official sign-up pages of Bitget, Pionex, WEEX and BTCC don’t show a rate, whichever code is filled in, so for these 4 I could only record the numbers posted online. The rate has to be confirmed in your account after you sign up:
| Exchange | Codes found | Rates claimed online | What the official sign-up page shows | Where to check after signing up |
|---|---|---|---|---|
| Bitget | 17 codes | 8 claim 30% to 60%, 2 claim 20%, 7 give no number | Only the invite code, filled in; no rate and no referrer information | Your fee or rebate records |
| Pionex | 19 codes | 6 claim 50% to 60%, 8 claim 20%, 5 give no number | Only the referrer’s profile picture and nickname | In the app, tap your profile picture and look under Referral Code; on the web, use the i icon next to Referral Code (Pionex help, checked 2026-11-02) |
| WEEX | 5 codes | Mostly a 20% to 50% fee discount, or only a sign-up reward | Only a sign-up reward, no rate | The rebates credited to your account after you make a trade |
| BTCC | Not collected separately | — | This site’s code, another public code and a code I made up all show exactly the same new-user reward | The cashback amount in your fund records after you make a trade |
At Pionex, regular inviters and agents can share at most 20% on spot and 15% on futures with friends. A code claiming 50% to 60% could only get there with a rate individually negotiated for a KOL, and there’s no way to confirm that before you sign up. Screenshots of this site’s rates at these 4 exchanges are on each exchange’s referral code page: Bitget referral code, Pionex referral code, WEEX referral code and BTCC referral code.
Where do the higher rates posted online come from?
Numbers above the official cap
The most common method is adding the referral code rebate to a platform token fee discount. Binance’s “40%” is the code’s 20% plus the 25% spot discount for paying fees with BNB (0.8 × 0.75 = 0.6, so you pay 40% less). Gate’s “55%” is 40% plus the GT discount, and MEXC’s “70%” is the code’s 20% plus the discount for paying fees with MX. Any account can turn on a platform token discount by itself; it has nothing to do with the referral code.
The other method presents the referrer’s own commission as the invitee’s discount. KuCoin’s affiliate program advertises referrer commission of “up to 60%” (KuCoin Affiliate Program 2025 guide), and Gate’s referral page advertises referrer commission of “up to 40%” (Gate referral rebate page). These are caps on the referrer’s commission, and whatever the invitee gets is carved out of them (both checked 2026-11-02). For a full breakdown of numbers like 40% and 55%, see exchange rebates and extra rebates explained.
What the 62 codes claiming more than the official cap actually give (codes)
Codes for Binance, OKX, Gate, MEXC, BingX and HTX; none goes above the cap
- 0%31
- A rebate, but below the cap7
- Exactly the official cap18
- No rate shown on the sign-up page6
A code that states the cap doesn’t always give the cap
58 codes state a rate exactly equal to the official cap, for example the “20%” at Binance, OKX and MEXC. Of the 47 that could be checked, 23 really give the cap and 24 give less, 19 of them 0%. Two codes advertising the same cap can therefore give very different results, and the most reliable check is to enter a code on the official sign-up page once before you use it.
For “lifetime” or “permanent”, check the exchange’s own terms
52 codes are labeled “lifetime” or “permanent”. Of the 42 that could be checked, 13 give the official cap and 19 give 0%. How long a rebate lasts depends on the term and stop conditions the exchange itself publishes. Take Binance: it sets no term for the spot rebate, but once you reach VIP 3 or above, both spot and futures commissions stop. The futures rebate runs for 12 months from when you open a futures account, a limit that doesn’t apply if the referrer’s futures commission rate is 30% or more (Binance Referral Pro FAQ, verified 2026-10-10).
Sign-up rewards and rebates are two different things
New-user rewards and referral code rebates are set separately. At Binance, 7 codes give a 0% trading fee rebate, yet the sign-up page still shows a sign-up reward of up to 19,800 USD; at OKX, 21 codes open a new-user mystery box page that shows only rewards and no rate. BingX referrers can add their own introduction text to the sign-up page. I came across a 0% code whose introduction promised “30% off” fees, yet the cashback rate line the system shows below the invite code field never appeared. When you check the rate, go by the line the exchange’s system displays.
Codes from the same person can give different rates
Each code has its own rate. One Binance referrer has 4 codes at 20% and 1 at 0%; one BingX referrer’s 5 codes give 20%, 10%, 0%, 0% and 0%; at Gate, 5 codes under the same nickname give 20%, 20%, 10%, 0% and 0%. In 3 other cases, the text gave one code while the button linked to a different one. The code you bind is the one in the link you click, so a quick look at the referral code field before you submit keeps you from mixing them up.
Plenty of sites state the rate accurately
Of the 207 codes that state a specific rate and could be checked, 61 match what they say, and 2 actually give more than they state. Review and comparison sites that quote specific figures such as 5%, 10%, 15% or 25% mostly take the rate straight from the sign-up page, and their numbers matched the page when I checked.
How can you check a referral code’s rebate yourself?
At most exchanges, the official sign-up page shows what a code gives before you sign up, so you don’t need to rely on any website’s own numbers. Check it in these steps:
- Open the exchange’s official sign-up page from the referral link and make sure the domain belongs to the exchange.
- Look for the rate where the table below says to: usually below the referral code field, on the referrer card or in the page heading.
- If you can’t see a rate, it depends on the exchange. At Binance, BingX, MEXC and LBank, and on HTX’s Traditional and Simplified Chinese sign-up pages (spot), a rate is shown whenever there is one, so no rate means 0%. Bitget, Pionex, WEEX and BTCC never show it, so you’ll need to check in your account after signing up.
- Before you submit your registration, make sure the code in the referral code field is the one you want to use.
- After signing up, confirm the binding on the exchange’s referral or rebate page; where to look at each exchange is covered in how to check your referral code.
| Exchange | Where the official sign-up page shows the rate | Open with this site’s link |
|---|---|---|
| Binance | A card showing a trading fee rebate of up to X%; no card means 0% | Binance sign-up page |
| OKX | A heading offering X% off trading fees; on pages that show only a new-user reward, check the rate after signing up under “My Rewards” in the app | OKX sign-up page |
| Gate | The rebate rate for each market listed on the promotion page, or the line below the invite card saying you’ll get an X% fee rebate reward when you sign up and complete a trade | Gate sign-up page |
| MEXC | Below the invite code field, the fee sharing rate: spot X% / futures Y% | MEXC sign-up page |
| BingX | Below the invite code field, a line saying you’ll enjoy an X% cashback rate | BingX sign-up page |
| KuCoin | A green X% cashback tag on the referrer card; the layout varies by region, and if there’s no card, check the cashback credited in your asset records after signing up | KuCoin sign-up page |
| HTX | Below the heading on the Traditional and Simplified Chinese sign-up pages, a line offering an X% fee rebate (spot) | HTX sign-up page |
| XT.COM | For 6-character codes, the line below the field shows your futures cashback rate (X%) and spot rate (Y%); for other codes, check the refunded amounts in your fund records after signing up | XT.COM sign-up page |
| LBank | Below the referral code, a line saying you’ll get an X% futures fee discount | LBank sign-up page |
| Ourbit | When a code has spot, futures and DEX rebates all set, the line below the field shows X% futures and Y% DEX fee cashback; for other codes, check the Referral page after signing up | Ourbit sign-up page |
Take this site’s Binance code as an example: open my Binance invite link and the card shows a trading fee rebate of up to 20%. If you’d rather enter it yourself, the code is KEVINWU.
Sign-up page and dashboard screenshots for this site’s code at each exchange are collected in referral rebate proof; every referral code and the rules for adding one later are in the exchange referral code overview.
When is the next test?
This report is rechecked every quarter. The next check is planned for February 2027, using the same method on the same exchanges, plus any new codes I find. This site’s rates sync with the exchanges daily, and any change is logged with its date automatically in the exchange rebate rate monthly report.
FAQ
Are the 50% and 55% referral codes posted online real?
At the 7 exchanges that publish a cap, none of the codes I checked went above the official cap. Of the 62 codes that claim more than the cap, 56 had a checkable rate: 31 of those are 0% and 18 are exactly at the cap. These numbers mostly come from adding a platform token discount to the referral rebate, or from presenting the referrer’s own commission cap as the invitee’s discount.
If the sign-up page shows no rate, does the code give 0%?
It depends on the exchange. At Binance, BingX, MEXC and LBank, and on HTX’s Traditional and Simplified Chinese sign-up pages (spot), a rate is shown whenever there is one, so no rate means 0%. The sign-up pages of Bitget, Pionex, WEEX and BTCC don’t show any code’s rate, and some OKX promotion pages, XT.COM codes that aren’t 6 characters long, and Ourbit codes without a DEX rebate don’t show one either. In these cases, check in your account after signing up.
Can you trust a code that promises a lifetime rebate?
Check the rate first, then the term. Of the 52 codes labeled “lifetime” or “permanent”, 42 had a checkable rate, and 19 of those are 0%. How long a rebate lasts is set by the exchange’s own term and stop conditions; at Binance, for example, referral commission stops once you reach VIP 3 or above.
Is this site’s referral code rebate the highest?
At the 10 exchanges where the rate could be checked this time, no public code gives a higher spot or futures rebate than this site’s code, which is basically the highest among them; at Binance, OKX, Gate, MEXC, BingX and KuCoin it gives the official cap. Bitget, Pionex, WEEX and BTCC don’t show the rate on the sign-up page, so for this site’s rate there, see the screenshots on each exchange’s referral code page.
Why not publish the other codes you checked?
This report sets out to show what referral codes found online generally give, so it looks only at the overall figures, and a code’s rate can also change whenever its referrer adjusts the settings. That’s why it publishes only statistics and anonymous examples. To check a particular code, enter it on the official sign-up page using the steps above; that gives you the most accurate answer at that moment.
Already signed up? Can you still add a referral code?
If your account has no referrer yet, many exchanges let you add one within a set period; at Binance and MEXC, for example, it’s within 30 days of signing up. Each exchange’s conditions and steps are in can you add a referral code after signing up.
