How to link a phone number to MEXC? (Account Binding)

Accessing the Account Security Section

1. Log in to your MEXC account using your registered email or phone number and password.

2. Hover over your profile icon located in the top-right corner of the interface.

3. From the dropdown menu, select Security Settings or Account Security.

4. Scroll down until you locate the Phone Number Binding section.

5. Click the Bind or Add Phone Number button adjacent to that section.

Entering and Verifying Your Mobile Number

1. Select your country or region from the dropdown list to ensure correct formatting.

2. Input your full mobile number without leading zeros or plus signs unless explicitly required.

3. Click Send Verification Code to trigger an SMS containing a six-digit numeric code.

4. Open your messaging app and retrieve the code sent by MEXC.

5. Enter the received code into the designated field on the MEXC page within its validity window.

Confirming Binding Completion

1. After successful verification, the system displays a confirmation message indicating binding status.

2. The bound phone number appears under the Phone Number label with a green checkmark icon.

3. You may see options to Edit, Unbind, or Set as Primary next to the number.

4. A notification email is dispatched to your registered email address confirming the update.

5. The phone number becomes immediately active for login recovery and two-factor authentication fallback.

Security Implications of Phone Binding

1. Bound numbers enable SMS-based one-time passwords during sensitive operations like withdrawals.

2. They serve as a secondary identity verification channel if email access is temporarily lost.

3. Binding restricts unauthorized changes — any attempt to unbind requires re-authentication via existing 2FA.

4. The number is never shared with third parties and remains encrypted in MEXC’s internal infrastructure.

5. Binding does not replace Google Authenticator; both methods operate independently and can coexist.

Frequently Asked Questions

Q1: Can I bind more than one phone number to a single MEXC account?Only one phone number may be actively bound per MEXC account at any given time. Attempting to add another automatically replaces the prior binding after verification.

Q2: What happens if I lose access to my bound phone number?You must initiate account recovery through verified email or completed KYC documents. No automated unbinding occurs without multi-layered identity validation.

Q3: Is phone binding mandatory for trading on MEXC?It is not mandatory for basic spot trading, but it is required for futures, margin, and withdrawal functions. Unbound accounts face strict daily limits on fund movement.

Q4: Why did my verification code fail even though I entered it correctly?Codes expire after 5 minutes and are case-sensitive in some legacy interfaces. Network delays or duplicate submission attempts may invalidate pending codes before entry.
