What are invite codes and rebates? How much you save and where to enter them
That "invite / referral code" box at exchange sign-up gets skipped by a lot of people. But behind it is a fee discount tied to your account — whether you get it, and how much, depends on the exchange's current rules and your account's eligibility. This guide explains what invite codes and rebates are, and tells you exactly how much you save and where the code goes.
"Enter a code and save money? Sounds like a gimmick." That's many beginners' first reaction, and it's fair. But invite codes aren't mysterious — they're a sign-up mechanism the exchange itself designed, with the rules out in the open. We'll take it apart so you can decide for yourself whether to use it.
How invite codes and rebates work
An invite code is just a string of characters (like GOD166). Enter it in the "invite / referral code" box at sign-up and the exchange counts you as a user who came in through that referral, setting up a "referral relationship".
From then on, each time you trade, the exchange charges its usual fee, but it shares part of what it takes back out — that's the rebate. Officially the exchanges call this mechanism cashback. In most user-facing setups, that rebate can reach you as a fee discount: for the same trade, you with a code stand to pay less than someone without one.
Take that "can" seriously: the discount is worked out by product (spot, futures and so on), the region you're in, your account's eligibility and the campaign running at the time. Entering a code does not mean it automatically applies, forever, to all of your trades. The real rate is whatever the sign-up page shows and whatever the exchange's current rules set.
Why the exchange is willing to give you a discount
Because acquiring users is hugely valuable to an exchange. One more long-term trader earns the exchange far more in fees than the small discount it shares back. So it's happy to give up a slice to reward "bringing newcomers in" — the same logic as the "invite a friend, both get a reward" perks in many apps, except here what's shared back is fees rather than coupons.
This is also why this site can give you guides for free: when you sign up through our links and codes, the exchange may pay the site a referral commission; and on your side, whether there's a fee discount and how big it is comes down to the exchange's current rules and your account's eligibility. It's an arrangement that benefits both sides and is spelled out plainly in our referral disclosure — and it doesn't change what we should say when writing the content.
How much you save: the math
How much exactly depends on the discount ratio. We'll use a common setup: a standard spot rate of 0.1%, becoming about 0.085% after the code discount (it varies by exchange and tier; the logic is the same).
| Case | Rate | Fee on a $10,000 round trip |
|---|---|---|
| No invite code | 0.1% | about $20 |
| With invite code (est. 0.085%) | 0.085% | about $17 |
About $3 saved per round trip. One trade looks unremarkable, but remember two things: first, it isn't a one-off — while your eligibility holds, later trades are worked out under the rules in force at the time; second, it may stack with other savers, though whether it stacks, and in what order, is set by the exchange's current rules. Add Binance's BNB discount and the habit of being a maker, and with several layers off, an active user's monthly saving is substantial.
Which step the invite code goes in
This is the one thing to remember from the whole article: the invite code goes in at the sign-up step and can't be added later. For Binance spot, the official documentation says the referral code must be entered at registration: forget it or get it wrong and you won't receive the cashback, with no way to apply it retroactively. The only exception is futures — you can still enter a futures referral code before you open the futures account.
The exact spot differs a little by exchange, but it's roughly always on the sign-up page or within the sign-up flow:
- Some have an "invite / referral code" field right on the sign-up form, sometimes collapsed by default, so you have to tap "expand" or "optional" to see it — don't miss it just because it's tucked away.
- Some registration pages support a dedicated link with the invite code built in. The field may be filled automatically, but you should still verify the invite-code box before submitting.
The safest approach is to verify the exchange's official domain, then enter or confirm the invite code in the registration form. Referral attribution usually cannot be added after the account is created, so have the code ready first.
Our codes for five exchanges
The five invite codes we record and check are listed below; eligibility and discount rates are subject to each platform's current rules:
| Exchange | Invite code |
|---|---|
| Binance | GOD166 |
| OKX | GOD166 |
| Bitget | GOD166 |
| Bybit | GOD166 |
| Gate.io | GATEOKKK |
If you can't remember them — the first four are GOD166, and Gate.io alone is GATEOKKK. To see one exchange's full sign-up flow, read how to sign up for Binance: phone / email + identity verification, where the code-entry step is marked clearly.
A few common questions
What exactly is an invite code?
A string of characters in an exchange's referral system. Enter it and the exchange counts you as a referred user and may share part of what it takes from your fees back to you as a discount (the rebate); whether it applies and at what rate depends on the product, your region, your account's eligibility and the current rules.
How much does it save?
It depends on the discount ratio, commonly a cut off the standard rate. While your eligibility holds, later trades are worked out under the rules in force at the time, and it may stack with other savers, though the exchange decides that; the real rate is whatever the sign-up page shows at the time.
If I forgot, can I add it?
For spot, no: the official documentation says the referral code must be entered at registration, and if you forget it or get it wrong you won't receive the cashback, with no retroactive route. The only exception is futures — you can still enter a futures referral code before you open the futures account. Have the code ready beforehand (the first four are GOD166, Gate.io is GATEOKKK).
Invite-code note: If you decide to open a Binance account, you can use invite code GOD166 on the Binance registration page. Whether a fee discount is available, and its amount, is subject to Binance's current rules and account eligibility.
