How to Change Your Binance Linked Phone Number

Changing phone numbers is a common life event — whether you are switching carriers, relocating, or your old number has been cancelled. Since your phone number is a critical component of Binance account security verification, the change process requires strict identity verification. This article covers the complete change flow for two situations: when your old number is still accessible and when it is not.

Situation 1: Your Old Phone Number Can Still Receive SMS

If your old phone number can still receive SMS messages, the process is relatively straightforward. Follow these steps:

Step 1: Go to Security Settings

Log in to your Binance account, click your avatar in the upper right corner to go to "Profile," then select "Security." Find the "Phone Verification" option on the security settings page.

Step 2: Click Change

In the phone verification section, you will see your currently linked phone number (with some digits hidden). Click the "Change" or "Update" button next to it.

Step 3: Verify your old phone number

The system sends an SMS verification code to your currently linked old phone number. Enter the 6-digit code you receive.

Step 4: Complete additional security verification

In addition to verifying the old phone number, the system will also require one or more of the following:

• Email verification code
• Google Authenticator code
• Fund password

Step 5: Link your new phone number

After all security verifications pass, enter your new phone number (including the correct country code). The system sends an SMS verification code to the new number — enter it to confirm.

Step 6: Change successful

After verification, the phone number change takes effect immediately. The system sends change notifications to both the old and new phone numbers, and a 24-hour withdrawal freeze is triggered.

Situation 2: Your Old Phone Number Is No Longer Accessible

If your old phone number has been cancelled, suspended, or lost, and you cannot receive SMS verification codes, the process is more complex and requires a manual review by Binance's support team.

Option 1: Submit a request via live customer support

1. Log in to your Binance account (if you cannot log in, first reset your password via email)
2. Go to the Binance Customer Support center, select "Live Chat"
3. Explain that you need to change your linked phone number, and that the old number is no longer accessible
4. The agent will ask you to provide identity verification materials:
   • A photo of the front of your ID document
   • A photo of the back of your ID document
   • A selfie holding a handwritten note with today's date and the text "Request to change Binance linked phone number"
   • Screenshots of recent account activity (optional)
5. Submit the materials and wait for review, typically 1–3 business days
6. After approval, the agent will remove the old phone number binding, and you can then link your new number

Option 2: Use the "Verification unavailable" option in Security Settings

In some cases, you will find a "Security Verification Unavailable?" or "Can't receive verification code?" link at the bottom of the phone verification page. Clicking this will guide you through alternative verification such as facial recognition.

Specific steps:

1. Tap "Security Verification Unavailable"
2. Select "Phone Verification Unavailable"
3. The system may ask you to complete facial recognition
4. Upload ID document photos
5. Complete video verification (follow on-screen prompts and perform specified actions)
6. Wait for automated review — once approved, you can set a new phone number

Security Restrictions After Changing Your Phone Number

To protect account security, Binance applies the following restrictions after a phone number change:

• 24-hour withdrawal freeze: You cannot withdraw cryptocurrency to external addresses within 24 hours of the phone change
• Temporary functional restrictions: Some sensitive operations (such as changing your password or disabling security verification) may be restricted for 48 hours
• Notifications: The system sends change alerts to your email and the old phone number (if still accessible)

These restrictions exist so that, in the event of unauthorized access, the actual account holder has time to respond. If you see a phone number change that you did not initiate, immediately contact Binance customer support to freeze your account.

Important Notes When Changing Your Phone Number

Before and during the change process, keep the following in mind:

1. Confirm that the new phone number can receive SMS before linking: Avoid discovering reception issues only after already linking the new number
2. Make sure other security verification methods are working: Changing your phone number requires support from other verification methods — confirm your email is accessible and Google Authenticator is working
3. Do not operate from public networks: When modifying security settings, ensure you are on a trusted network — avoid using public Wi-Fi
4. Back up your Google Authenticator key: If your phone number and Google Authenticator are both on the same device, remember to transfer the authenticator when switching phones
5. Use a phone number registered under your real identity: Real-name registered phone numbers are easier to pass through manual review processes

Frequently Asked Questions (FAQ)

Q1: How long does changing a phone number take?

If the old number is accessible, the entire process takes only 5–10 minutes. If manual review by the support team is needed, it typically takes 1–3 business days. During the review period, you can still log in and trade normally — you just cannot complete operations that require phone verification.

Q2: Can I link an international phone number?

Yes. Binance supports phone numbers from most countries and regions worldwide. When linking, select the correct country code. Some regions may have less stable SMS delivery — if you cannot receive verification codes, contact customer support for assistance.

Q3: If both my phone number and email are inaccessible, can I still recover my account?

Yes, but the process is more involved. You will need to contact Binance customer support for a comprehensive identity verification process, including submitting ID documents, facial recognition, account registration information, and more. We strongly recommend keeping your email and phone number secure, and enabling multiple security verification methods to avoid the extreme situation where all your verification channels are unavailable.

Summary

Changing your Binance linked phone number involves multiple security verification steps, but Binance provides a complete safety mechanism to ensure the process is secure. The process is simpler when the old number is accessible; without it, additional identity verification is required. Regardless of the situation, operate on a trusted network and make sure other security methods are working before you start.
