How to Use a Binance Invite Code: Where to Enter It and How Much You Save on Fees
"Does entering this code mean I have to pay the referrer extra?" That's probably the single most common misunderstanding about invite codes. The answer is simple: no — and it's actually the opposite. It looks like some kind of sales pitch, but underneath it's a coupon you'd be silly to leave on the table. This guide explains it fully, and answers a few questions that keep coming up while we're at it.
What an invite code / referral code actually is
Binance runs a referral program — common across the internet industry — and the concept is well covered in Investopedia's explainer on referral marketing. When someone signs up through an invite code, the system links the two accounts so the newly registered person gets a percentage rebate on fees. For you, the new user, the only effect of entering the code is this — you pay a little less in fees on your trades afterward, and you're never charged anything extra.
So "invite code," "referral code," and "referral ID" are all the same kind of thing: a string used to attach the offer to your account. Different names, same job. The one this site uses is BNB3311.
This kind of program exists because the platform is willing to give back a slice of its marketing budget to encourage word-of-mouth: the referrer gets their reward on their end, you get the rebate, and both sides get what they want. Once you understand that layer, you stop being wary of that one little field. Worth noting: the offer is locked in at the moment you sign up and has nothing to do with how much money you make later or how big your trades are. It isn't "the platform handing you free money," nor is it a sure thing — it just nudges your fee rate down a notch, and the effect adds up over time.
Where BNB3311 goes on the sign-up page
In the full registration flow, entering the code is one of the steps. Specifically: on the page where you've set your password and are about to submit, there's an "invite code / referral code" field. It's often collapsed, so you have to tap that expand link first for the input box to appear, then paste BNB3311 in. That's all.
The easier route is this: enter the sign-up page from a link that already carries the referral info, and a lot of the time the system fills the code in automatically — you just confirm the page shows the attached code or referrer before you submit. The button below is exactly that kind of link.
Whether you fill it in by hand or use a coded link, there's one small habit worth building: before you submit, pause a second and glance at the page to check a code or referrer is showing. That glance takes less than three seconds, but it blocks the most common regret of all — "I thought I'd entered it, but I hadn't." Binance moves the field's position around occasionally, but "check once before you submit" works forever.
A while back we opened an account twice — once entering the code by hand, once through a coded link. The manual one almost slipped through: the field really is collapsed, and if you're not paying attention it's easy to skip right past it. The coded link was much smoother — by the time we got there the code was already filled in, and all we had to do was spot it on the final confirmation before submitting. So if you're worried about forgetting, a coded link is the safer bet.
If you forgot to enter it, can you add it later?
This is the practical one: in most cases, once you've finished signing up, you can't add the code afterward. The referral relationship is usually set the instant the account is created — it's not like a coupon you can punch in later, which is why we keep stressing "the moment you sign up" as the time to get it in.
If you've already finished registering and you're sure you didn't enter it, don't beat yourself up — you still have a normal fee rate, you're just missing that bit of rebate. If it really bothers you, you can check the referral terms in Binance's official support center or ask support what the current policy is, but don't count on being able to add it. The more useful mindset: now you know, and next time you help a friend open an account, remember to remind them to enter it first.
How the rebate is actually calculated
Signing up with BNB3311 attaches a up to 20% fee rebate — meaning the fee you pay on each trade gets a discount off the base rate. The actual percentage is whatever Binance shows on its page and may change with their policy, so I won't pin down a fixed number here that's "true forever" — that's our consistent stance on anything fee-related. For the exact fee structure as it stands now, the most reliable source is Binance's own fee overview and official support center.
To see what a single trade actually saves you, the most direct way is to plug the trade amount and whether you're a maker or a taker into our fee calculator and read the result. The full logic — what separates maker from taker, and why it affects your cost — is covered in more depth in how Binance fees are calculated.
Here's a gut-feel version: the amount saved on a single trade is often tiny, small enough that you might think it doesn't matter. But fees are charged on "every single trade," and across a whole year of steady trading they stop being loose change. It isn't about saving a lot in one go — it's about paying a little less, drip by drip, over the long run. Which is exactly why it's worth getting the code in at the moment you sign up.
One more thing: what you actually pay also depends on whether you're a "maker" or a "taker" — the two have different rates, and Investopedia's explainer on maker-taker lays it out clearly. The invite-code rebate sits on top of that base rate, so treat the two as separate things.
Does it stack with the BNB discount?
Yes — they're two different things, and you can use them together. In short:
- Invite-code rebate: nudges your fee rate down by a percentage.
- BNB fee discount: pay your fees with the BNB in your account, and you usually get an extra layer of discount. For what BNB is, see Investopedia's intro to BNB.
The two work at different points, so when you turn on paying fees with BNB, the rebate from the invite code is generally still there too — and for anyone trading over the long run, using both makes a real difference. Whether to hold BNB and how to turn the discount on are covered more fully in the fees guide.
One caution, though: BNB is itself an asset that goes up and down, so buying a pile of it just to save on fees isn't necessarily worth it — it depends on your trading volume. At the beginner stage I'd suggest locking in the free rebate from the invite code first, and weighing up the BNB discount once you're more familiar and sure you'll keep trading. Take the cost-free benefits in full first — that's the steadiest order.
A few questions people keep asking
Does entering a code leak my data to the referrer?
No. The referrer can't see your identity, account contents, or trade history — the two of you are anonymous to each other. It only attaches the offer to your account; it doesn't hand over your privacy.
Is the offer the same for every code?
The percentage varies with platform policy and the referrer's settings. The BNB3311 this site uses corresponds to a up to 20% fee rebate; the actual figure is whatever your sign-up page shows.
Are there other steps after entering the code?
No. The code is just one field in the sign-up flow — once it's in, you finish identity verification and funding as usual and you're ready to go.
Can I use this code for my whole family on one phone?
The invite code attaches to the "account," not the device. When you help family members each register their own accounts, every account can enter BNB3311 in that field — they don't conflict with each other. Just remember to enter it once for each person.
Ultimately, the invite code isn't complicated — remember to enter BNB3311 at the moment you sign up, and your trades carry the rebate from then on. The thing that trips people up is never the code itself; it's forgetting to enter it. If you're about to open an account, copy the code now.
