Your UID (User ID) is a unique numerical or alphanumeric identifier linked to your trading account. It’s often required for verification, support, or linking your account with external services.
🔍 Where to find your UID
On most exchanges and trading platforms, your UID can typically be found in the following places:
Under your profile icon (usually in the top-right corner after login)
In the Account, User Center, or Security Settings section
Near your username
Next to a label like UID, User ID, or Account ID
It often looks like a string of numbers (e.g., UID: 2199119XXXX) and is sometimes accompanied by a copy button 📋 for convenience.
