What Is a Binance UID?
Your Binance UID is a 9-digit unique identifier assigned to your Binance account. It’s used for customer support, internal transfers, and third-party integrations like Backcom.
How to Find Your UID on the Binance Website
- Log in to your Binance account at binance.com.
- Hover over the profile icon in the top-right corner.
- Click [Dashboard] in the dropdown menu.
- Your UID will appear at the top of the dashboard—right next to your email or nickname.


How to Find Your UID on the Binance App
- Open the Binance mobile app and log in.
- Tap the Account Center icon (top-left corner).
- Your UID will be displayed above your nickname or email. Tap it to copy.

Tips & Notes
- Don’t confuse UID with Pay ID (used for Binance Pay).
- It’s safe to share your UID with trusted services like Backcom—but never share your password or security codes.
- If you can’t find your UID, you can contact Binance Support for help.
