How to find your MEXC UID? (Account Information)

Locating Your MEXC UID Through the Mobile Application

1. Launch the official MEXC mobile app and log in using your registered email or phone number along with your password.

2. Tap the “Me” icon located at the bottom-right corner of the screen.

3. On the personal profile page, scroll to the top section where your account details are displayed.

4. Look for the label marked “UID”, “User ID”, or occasionally “MEXC ID” — it appears as a numeric string (e.g., 987654321).

5. Some interface versions display this identifier directly beneath your username or avatar; others place it beside the “Account Security” or “Profile Settings” entry.

Identifying Your UID via Desktop Web Interface

1. Access the MEXC website at https://www.mexc.com/ using a desktop browser and sign in securely.

2. Hover your cursor over the user avatar icon in the top-right corner of the page.

3. From the dropdown menu, select “Account Center” or “Personal Information”.

4. Navigate to the “Basic Information” tab within the account dashboard.

5. Your UID appears prominently in a read-only field labeled “User ID”, typically aligned next to your registered email or phone number.

UID Visibility During Transaction and API Activities

1. When initiating a deposit request, the UID is automatically embedded in the memo field for certain cryptocurrencies like XRP or XLM.

2. In the “API Management” section under “Security Center”, newly created API keys are tied to your UID, which is shown in grayed-out text above each key name.

3. Withdrawal confirmation pages often list your UID alongside the destination address and network fee breakdown.

4. If you submit a support ticket, the system auto-fills your UID in the hidden metadata — customer service agents reference this value to locate your account instantly.

5. Trading bot configuration panels on third-party platforms require manual entry of your MEXC UID when linking accounts via REST or WebSocket APIs.

UID Retrieval After Account Recovery

1. Following a password reset or two-factor authentication recovery, the login success page displays a temporary banner showing your UID for five seconds.

2. The recovery email sent to your registered address contains a line reading “Your UID: [number]” in plain text, placed just before the security reminder paragraph.

3. If you use Google Authenticator for 2FA, the authenticator app’s account label often defaults to “MEXC-[UID]” after initial setup.

4. During KYC verification submission, the upload confirmation screen shows your UID inside a blue-bordered info box labeled “Verification Reference ID”.

5. Re-logged-in sessions after prolonged inactivity trigger a toast notification stating “Welcome back, UID [number]” in the bottom-right corner.

Frequently Asked Questions

Q: Can my MEXC UID change after upgrading my KYC level?A: No. The UID remains permanently fixed once assigned during initial registration. It does not vary with verification status, account tier, or security settings.

Q: Is the UID the same across all MEXC domains like mexc.com and mexc.tv?A: Yes. A single UID serves as the universal identifier across all official MEXC web properties, regional subdomains, and supported language interfaces.

Q: Why does my UID not appear when I’m logged in via SSO using Google or Apple ID?A: SSO sessions may delay full profile loading. Refresh the page or navigate to “Account Center” manually — the UID always renders after full authentication handshake completes.

Q: Can I hide or mask my UID from other users on the platform?A: No. The UID is never publicly exposed outside your own interface. It is not visible in chat, referral links, or community profiles — only accessible within your authenticated session.
