How to change your phone number on Binance? (Security Update)

Accessing Account Security Settings

1. Log in to your Binance account using your current credentials and complete any active two-factor authentication prompts.

2. Navigate to the top-right corner of the dashboard and click on your profile icon.

3. Select Security from the dropdown menu to enter the dedicated security management interface.

4. Scroll down to the Phone Number section under the “Verification Methods” category.

5. Click the Edit button adjacent to the currently registered number.

Verifying Identity Before Modification

1. Binance requires identity confirmation before allowing phone number changes to prevent unauthorized access.

2. You will be prompted to enter your current password or approve a login request via your existing authenticator app.

3. If you have previously enabled biometric login, the system may ask for fingerprint or face verification.

4. A time-sensitive SMS code will be sent to your old number — this step cannot be bypassed even if the device is lost.

5. Input the received code within 5 minutes; failure results in temporary lockout of the edit function.

Entering and Confirming New Contact Details

1. After passing identity checks, a form appears requesting country code and new mobile number.

2. Select your region from the dropdown list to auto-populate the correct country prefix.

3. Type the full number without spaces or special characters — only digits are accepted.

4. Click Send Verification Code to trigger an SMS to the new device.

5. Enter the six-digit code delivered to the new number and press Confirm.

Post-Update Security Implications

1. The old number ceases to receive SMS-based login codes or withdrawal confirmations immediately after confirmation.

2. All future two-factor authentication requests via SMS will route exclusively to the updated device.

3. If Google Authenticator or hardware keys are also configured, they remain fully operational and unaffected.

4. Binance logs the timestamp, IP address, and geolocation of the modification event in your security history.

5. Any pending withdrawal approvals tied to the old number expire instantly upon successful update.

Frequently Asked Questions

Q1. What if I no longer have access to my old phone number? A1. You must submit a verified identity document through Binance’s Account Recovery Portal, followed by a manual review process that typically takes 3–5 business days.

Q2. Can I change my phone number while a withdrawal is pending? A2. No. Binance blocks phone number edits during active withdrawal processing. You must wait until the transaction status resolves to Completed or Cancelled.

Q3. Does updating my phone number affect API key permissions? A3. API key configurations remain unchanged. However, if those keys were created with SMS-bound restrictions, reauthorization may be required depending on your permission scope settings.

Q4. Why did my verification code fail even though I entered it correctly? A4. Codes expire after 180 seconds. Network delays, incorrect device time settings, or duplicate submission attempts can invalidate the token before entry.
