Changing phone numbers is common, but if your Binance account is linked to your old number, you need to update it promptly. Otherwise, you won't receive SMS verification codes, which may affect normal account usage and security.

Scenario 1: Old Phone Number Still Works
If your old phone number can still receive SMS, the process is straightforward.
Steps
- Log into your Binance account
- Go to "Security Center" or "Security"
- Find "Phone Number Verification"
- Click "Change"
- System sends a code to the old number
- Enter the code from the old number
- Enter your Google Authenticator code (if enabled)
- Enter the new phone number
- Request a code sent to the new number
- Enter the code from the new number
- Confirm the change
The entire process takes about 5 minutes.
Scenario 2: Old Phone Number No Longer Active
If the old number has been deactivated or reassigned, you can't receive codes — this makes things a bit more complex.
Option A: Use Alternative Verification
If you have Google Authenticator or other 2FA enabled:
- Log into your Binance account
- Go to the phone number settings in Security Center
- Select "Can't receive SMS verification code"
- Use Google Authenticator or email verification as a substitute
- Enter the new number and complete binding
Option B: Contact Support
If Option A doesn't work:
- Open Binance's support feature on the website or APP
- Select "Account Security" related issues
- Explain that you need to change your phone number but can't access the old one
- Follow support's guidance to submit identity verification materials
Support typically requires:
- Account registration email
- KYC ID document photos
- Selfie holding your ID with a handwritten note (date and request)
- Account UID
Review typically takes 1–5 business days.
After Changing Your Phone Number
Security Cooling Period
After the change, Binance activates a security cooling mechanism:
- Withdrawal functionality may be suspended for 24–48 hours
- Some sensitive operations face temporary restrictions
- This is a normal security safeguard
Check Other Security Settings
After changing your number, we recommend checking:
- 2FA settings are functioning normally
- Email binding is intact
- Withdrawal whitelist hasn't changed unexpectedly
- Recent login history looks normal
SMS Notification Updates
If you previously enabled SMS login alerts or trade notifications, these will automatically route to the new number after the change.
Notes for Different Regions
International Phone Numbers
- International phone numbers work normally on Binance
- Make sure the number can receive international SMS
- If your carrier blocks international SMS, you may not receive codes
Troubleshooting SMS Issues
If the new number isn't receiving Binance SMS codes:
- Check that international SMS is enabled (contact your carrier)
- Check if phone security software is intercepting messages
- Check if SMS filtering is turned on
- Try restarting your phone and resending
Using Overseas Phone Numbers
If you have an overseas phone number, you can use it for Binance binding:
- Select the correct country code
- Ensure the number can receive SMS
- Some virtual numbers may not be accepted
Prevention Tips
To avoid headaches from phone number changes:
Update in advance: Before you deactivate your old number, update the Binance binding first. Don't wait until the old number is gone.
Multiple verification methods: Don't rely solely on phone verification — also enable Google Authenticator and email verification. If your phone number has issues, you still have other ways to verify your identity.
Record account information: Save your Binance UID, registration email, and other details. You'll need them if you ever have to contact support for recovery.
Keep your number active: If you're not changing numbers but rarely use one, make sure it doesn't get recycled by your carrier due to inactivity.
Changing a phone number may seem like a small thing, but any security-related account changes shouldn't be taken lightly. Update your bindings promptly and maintain multiple verification methods to keep your Binance account secure and under your control.
