What should you do if your phone number is deactivated, your email is inaccessible, or you forgot your old bindings? Changing an email or phone number on Binance entails a strict multi-layer verification process. The whole process takes a minimum of 3 hours and a maximum of 7 days. This article details two scenarios: normal modifications when you can still log in vs. the recovery process when you are completely locked out. Before operating, open the Binance official website and enter the Security Center. Mobile users can also operate using the Binance official app; iOS users can refer to the iOS installation guide.
Scenario 1: Still Able to Log In (Normal Modification)
This is the most common situation. You still remember your password, can receive 2FA verification codes, and simply want to replace the bound email or phone number.
Complete Steps to Change Email
- Log into Binance → Profile Icon → Security
- Find the "Email" section, click "Change"
- The system will require you to complete 3-4 out of the following 4 verifications:
- Old email verification code
- Old phone SMS verification code
- 2FA (Google Authenticator) code
- Facial recognition (for advanced KYC users)
- After passing all required checks, enter your new email address
- The new email will receive a verification code; fill it back into the system
- Modification complete, the account enters a 24-hour withdrawal lock period
Process to Change Phone Number
The process is fundamentally the same, with the only differences being:
- In step 2, choose "Phone Number" → "Change"
- The final step involves receiving an SMS on your new phone number
Why the 24-Hour Lock?
This is a necessary anti-theft measure. If someone quietly changed your email or phone number, you have a 24-hour window to notice it and freeze the account. During the lock period, withdrawals, P2P trading, and unbinding 2FA are disabled.
Scenario 2: Old Email / Old Phone Number is Unavailable
This situation is more troublesome, but manageable. You must undergo the Account Recovery Appeal process.
Case A: Cannot Receive Emails on Old Email, but Can Receive SMS on Old Phone
- Log into Binance → Security → Change Email
- Click "Security verification unavailable?" (or similar wording for cannot receive old email code)
- The system will downgrade to alternative verification methods
- Enter 2FA + Old phone SMS + Facial recognition
- After passing, change to the new email
- Enter a 48-hour lock period (doubled from the normal lock)
Case B: Old Phone Deactivated, but Old Email Can Still Receive Emails
The exact opposite of Case A:
- Security → Change Phone Number
- Click "Security verification unavailable?" for the phone code
- Complete using 2FA + Old email verification + Facial recognition
- 48-hour lock period
Case C: Both Old Email and Old Phone Are Unavailable
You must go through the complete account recovery process:
- Login Page → Click "Can't log in?" → "Account Recovery"
- Fill in your KYC Name + ID Number
- Perform a liveness facial recognition recording
- Record a proof video as prompted, which includes:
- Today's date
- "I am XXX, and this is my Binance account recovery application"
- Displaying the original ID card (covering the middle 4 digits)
- After submission, wait 3-7 working days for manual review
- After approval, you will receive a password reset link
- Log in to rebind your new email and new phone number
- 7-Day Super Lock Period (all withdrawals strictly prohibited)
Security Reminders During the Modification Process
Do Not Trust "Customer Service Expediting"
There are often people posing as Binance customer service on social media claiming, "I can help expedite your binding modification, just provide me with the verification code." This is 100% a scam.
Real Binance customer service only replies through the official ticket system and will never ask you to provide verification codes.
Modify Using Your Original Device
If you use a new device to modify binding info, risk control will intervene immediately. Try to operate on the device you normally use to log in to reduce risk control interference.
Avoid Frequent Modifications
The same account can only modify its email or phone number once every 30 days. Exceeding this limit will result in forced downgrading, requiring advanced KYC again.
Must-Do Actions After Modification
1. Confirm the New Email Can Receive Notifications
Immediately after completing the change, send a test notification to the account yourself:
- Log into Binance → Security → Test Email Notification
- Or intentionally enter the wrong password once to trigger a login alert
If not received, immediately change it back or swap to another one.
2. Update All Third-Party Bindings
- If you logged into other platforms using your Binance email, synchronize the changes
- If you bound an API to a trading bot, check if the notification email is updated
3. Enable New 2FA
Some users retain their old 2FA. It is recommended to:
- Delete the old Google Authenticator entry
- Regenerate 2FA using the new email
- Write down the new backup codes
4. Update the Anti-Phishing Code
The anti-phishing code does not automatically expire after modifying bindings, but it is highly recommended to update it alongside them to prevent leaked old codes from being used.
Time Cost Comparison for Each Scenario
| Scenario | Verification Complexity | Lock Period | Total Time |
|---|---|---|---|
| Normal Email Change | Medium | 24 Hours | 30 Mins + 24 Hrs |
| Normal Phone Change | Medium | 24 Hours | 30 Mins + 24 Hrs |
| Lost Old Email Change | High | 48 Hours | 1 Hour + 48 Hrs |
| Lost Old Phone Change | High | 48 Hours | 1 Hour + 48 Hrs |
| Full Account Recovery | Highest | 7 Days | 3-7 Days + 7 Days |
Want to Avoid This Trouble? Prepare These in Advance
- Use permanently accessible emails for binding (e.g., Gmail, iCloud)
- Do not use company emails that expire
- Use your primary number for phone binding, not temporary or virtual numbers
- Regularly test whether your old email and old phone can still receive verification codes
- Backup your 2FA key to prevent losing 2FA when you lose your phone
Frequently Asked Questions
Q: Can I only use an email without binding a phone number?
A: Yes for new registrations, but some advanced features (advanced KYC, P2P, large withdrawals) require a bound phone number. It is recommended to bind it from the start.
Q: After changing the email, can the old email still be used to log in?
A: No. The old email is immediately unbound, and you can only log in with the new email.
Q: Can I trade during the "24-Hour Lock Period"?
A: You can do spot trading, but no withdrawals or P2P. This is to prevent stolen accounts from quickly transferring assets away.
Q: What if facial recognition fails during account recovery?
A: Check if the lighting is adequate, remove glasses and hats, and keep your face within the frame with no obstructions. After 3 failures, the system will force a 24-hour wait before you can try again.
