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 that can stay with your account for as long as you trade. 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. In most user-facing setups, that rebate lands on you directly as a fee discount: for the same trade, you with a code pay less than someone without one.
So invite code ≈ rebate ≈ long-term fee discount; you'll often see all three words in the same context, and they basically mean the same thing.
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 pays the site a referral rebate, and you get the fee discount. 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 applies to every future trade, not a one-off; second, it stacks with other savers. 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.
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 have you sign up through a dedicated link with the code built in, so the code is already filled and you just confirm it's there (the links in our right sidebar are this kind — click through and the code is already in).
So the safest move is: sign up via the coded link in the right sidebar, then double-check the invite-code box really has the right code. Once the account is created the referral relationship is fixed — which is exactly why we keep stressing: have the code ready before signing up.
Our codes for five exchanges
The five we use, and that we've checked ourselves, are below (sign up via the right sidebar and the code comes with it):
| 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, sharing part of what it takes from your fees back to you as a long-term discount (the rebate).
How much does it save?
It depends on the discount ratio, commonly a cut off the standard rate. It applies to every trade and stacks with other savers — the more you trade, the clearer it is.
If I forgot, can I add it?
Basically no — it's bound at the moment you register. Have the code ready beforehand (the first four are GOD166, Gate.io is GATEOKKK).
Spend ten seconds before signing up to lock in a long-term discount
The invite code can only go in at sign-up — never after. To open an account, go through the coded link in the right sidebar, check the code is right, then submit. Our five codes are in the right sidebar: the first four GOD166, Gate.io uses GATEOKKK.
