What is an OKX UID?
The first number to know after sign-up.
Support, friends sending you crypto and campaigns all ask for your UID. Here's what it is, where to find it, and when not to share it.
What does UID mean on OKX?
UID (User ID) is the unique number OKX assigns to your account when you sign up. It never changes.
| Detail | Used for | Can it change | Share it? |
|---|---|---|---|
| UID | Support, internal transfers, campaigns | No | Yes, with people who need it |
| Nickname, avatar | Shown in community and P2P | Yes | Public |
| Phone, email | Log-in and codes | Can be re-linked | Keep private |
| Password, codes, 2FA | Log-in and confirmations | Yes | Never |
Where do I find my OKX UID?
- App: tap your avatar in the top-left corner; the number under your nickname is your UID, with a copy button.
- Web: after logging in, click your avatar in the top-right corner.
- Not signed up yet: you don't have one; it is created when you register.
Can I send crypto using a UID?
Yes. OKX supports internal transfers by UID, phone or email between OKX accounts. They're usually instant and don't go on-chain.
- Check the masked nickname before confirming; mistakes are hard to reverse.
- Only send to people you know. Strangers asking for USDT to “unlock” or “activate” something are scammers.
- Never forward money for others. That's money-mule activity.
Is it safe to share my OKX UID?
A UID alone can't log in or show your balance, so sharing it with friends or official support is fine. Stop immediately if someone who asked for your UID then asks for passwords, codes or your authenticator, or says “give me your UID and log in here to receive cashback”.
How do I check my referral code applied?
Referral codes can only be entered at sign-up, so the key moment is checking the field shows OK66688 before you tap sign up. Afterwards you can compare the fee charged on a small spot trade with the fee schedule, or ask live chat with your UID.
Accounts created without a code can't add one later. If you haven't signed up yet, our buttons fill the code in for you.
No OKX account yet? Enter OK66688 when you sign up and OKX automatically charges you 20% less on every spot and futures trade, with no one else handling your money
