Bybit: Add a Referral Code Within 14 Days (Affiliate ID 163627)

Forgot to enter a referral code when you signed up for Bybit? You can still add one within 14 days of signup under "Join an Affiliate's Community" in your account. The field takes numbers only, so you enter affiliate ID 163627 rather than the signup code FEEOTTER. Once bound to Fee Otter the fee rebate is 40%, and after 14 days the only route left is a rebind (checked October 2026). This guide follows Bybit's official help article to cover the conditions, the website steps, how to check who you are bound to, and what to do after the 14 days.

Quick answer

• Deadline: within 14 days of signup. Later requests are not accepted.
• Enter affiliate ID 163627: the field hints say "Affiliate ID only" and "Numbers only", so the signup code FEEOTTER is rejected.
• Main accounts only, and the account must not have any referrer or affiliate yet.
• Once added, it cannot be cancelled or changed. Double-check 163627 before you submit.
• No "Join an Affiliate's Community" button? Then you don't qualify; see the Bybit rebind guide instead.
• Bind your UID on Fee Otter afterwards: rebates count fees from the moment you bind, not before.

Check these six conditions first

According to Bybit's help article How to Add and Check Registered Affiliate Code, all of the following must hold:

Bybit also says: if you don't see "Join an Affiliate's Community" on the Account Info page, you don't meet the conditions above. The button itself tells you whether you qualify.

How to add the code (website)

1. Log in to Bybit on the web, hover over Profile in the top-right corner and open your Account page.
2. On the Account Info tab, click Join an Affiliate's Community. You can also open the official request form directly after logging in.
3. Enter 163627 in the "Referral Code" field and a short reason, for example "Forgot to enter the code at signup" (up to 100 characters).
4. Read and acknowledge the disclaimer, then click Submit.
5. When it succeeds you are sent back to Account Info, and you're done.

The help article also has an app tab, but where the entry sits changes between app versions. The website path is the most stable, so use a desktop or mobile browser.

Why 163627 and not the signup code?

The same referral relationship takes a different value in two places:

The form field is labelled "Referral Code", but its tooltip says "Affiliate ID only" and the input says "Numbers only". 163627 is the affiliate ID behind our dedicated link: open the dedicated link and the address you land on carries affiliate_id=163627.

How to check which affiliate you are bound to

Go to Account Info and click the affiliate row to see the details. After a successful request it usually shows 163627.

Bybit also notes that some affiliates' IDs are hidden on that page because of their privacy settings. Not seeing an ID doesn't mean the request failed, and it doesn't affect your membership. The most direct way to confirm you are with Fee Otter is to bind your UID on the rebate dashboard: if it is approved, your account is under us.

After adding the code: bind your UID on Fee Otter

Adding the code only tells Bybit you belong to Fee Otter. You still need to bind your Bybit UID on the rebate dashboard before rebates are paid to you. Rebates count only fees generated after you bind your UID, not earlier ones, so add the code and bind your UID as early as you can. Binding needs only your UID: no API key, password or withdrawal permission.

The Bybit rebate rate is 40%, as shown below:

Past 14 days, or already have a referrer?

The request form is only open for 14 days, and a code you are already bound to cannot be changed. In both cases you can rebind instead:

• Option 1 (try first): register a new account through the dedicated link and verify it with an ID type you haven't used yet (a driving licence, passport and national ID can each verify one account).
• Option 2: register a new, unverified account through the dedicated link, then move your old account's KYC over.
• Option 3: if the account was registered on or after 1 September 2025 and hasn't traded for 180 days, log in through the dedicated link and then resume trading.

Full steps and limits are in the Bybit rebind guide for existing users.

FAQ

Can I still add a referral code after signing up for Bybit?

Yes, but only within 14 days of signup, on a main account with no referrer yet, and only for an affiliate code. For Fee Otter, enter affiliate ID 163627 in the form.

Why won't the form accept the signup code?

The request form takes only a numeric affiliate ID. The signup code FEEOTTER is made of letters, so enter 163627 instead.

Can I switch to a different affiliate after adding the code?

No. Bybit says a code cannot be cancelled or changed once added, so make sure you enter 163627.

I can't find the "Join an Affiliate's Community" button

Per Bybit, a missing button means you don't meet the conditions. The usual reasons are that more than 14 days have passed, the account already has a referrer, or you are logged in to a subaccount. Use the methods in the rebind guide instead.

Will I get rebates on fees paid before adding the code?

No. Fee Otter only counts fees generated after you bind your UID, so bind it on the rebate dashboard as soon as you've added the code.

Can I add a friend's referral code?

No. Referral codes from Bybit's Referral Program (generated by regular users) are not supported; only affiliate codes are.
