You can definitely change the phone number bound to your Binance account after registration. The entire process can be completed within 10 minutes, but it requires passing multiple identity verifications. Visit the Binance Official Site or open the Binance Official APP and log into your account. You can find the option to change it in the Security Center. For iPhone users, if the APP fails to launch, you can refer to the iOS Installation Guide to reinstall it. After a successful change, there will be a 24-hour withdrawal restriction period. This is to prevent assets from being immediately transferred if the account is compromised.
Why You Might Need to Change Your Phone Number
The need to change a bound phone number mainly arises from four scenarios: the original phone number is canceled and deactivated, the phone number is reclaimed by the carrier, changing countries and phone number segments, or the phone number is leaked and needs to be replaced. Regardless of the situation, Binance provides a complete change channel so that users' assets will not be locked.
According to statistics from Binance official customer service, about 3% of users apply to change their bound phone numbers every month, of which 70% is due to changing numbers or the carrier plan expiring and automatically deactivating.
Preparations Before Changing
Step 1: Confirm You Can Receive Verification Codes on the Original Number
If the original phone number can still be used normally, the change process will be very simple and only takes 5 minutes. The system will send verification codes to both the original number and the new number at the same time. After both are confirmed, the replacement is complete.
Step 2: Prepare Your Original ID Document
If the original phone number can no longer receive SMS messages, you need to go through the appeal process. At this time, you must submit photos of the front and back of your original ID document, as well as a selfie holding the ID. The appeal processing time is generally 1-3 working days.
Step 3: Close Ongoing Orders
Before changing the phone number, it is best to confirm that the account has no pending limit orders or ongoing C2C transactions. These incomplete operations may be affected, and it is recommended to settle or cancel them in advance.
Normal Change Process
Step 1: Enter the Security Center
After logging into your Binance account, click on your avatar in the upper right corner, and select "Account Security" from the drop-down menu. Find the "Phone Number" section on the security settings page, and there will be a "Change" button on the right.
Step 2: Complete Identity Verification
After clicking change, the system will require you to first pass the verification code of the currently bound phone number, as well as the email verification code and the 6-digit code from the Google Authenticator (2FA). These three verifications are all indispensable, and the purpose is to ensure that the account owner is performing the operation.
Step 3: Enter the New Phone Number
Make sure to select the correct country code when entering the new phone number. For example, mainland China is +86, Hong Kong is +852, and Taiwan is +886. After filling it out, click get verification code, and the new phone will receive a 6-digit SMS within 60 seconds.
Step 4: Confirm the Change
Check the prompt "I know that I cannot withdraw coins within 24 hours" in the pop-up confirmation box, and then click confirm. The system will complete the replacement within 10 seconds and push an email notification to your bound email address.
Change Method When the Original Phone Number is Unusable
If the original phone number has been deactivated, canceled, or the SIM card is lost, and you cannot receive the verification code, you need to go through the account appeal process.
Click "Forgot Phone Number" or "Account Appeal" on the login page, and fill in the basic information of the account, including the registration email, approximate registration time, past transaction records, etc. Then upload photos of your ID and a selfie video holding your ID. The video duration requirement is at least 10 seconds, and the clarity must be enough to see your facial features and the text on the document.
After the appeal is submitted, you will generally receive the processing result within 24-72 hours. If it is approved, customer service will send a security link via email. Click the link and set a new phone number.
Precautions After Changing
24-Hour Withdrawal Cooling-Off Period
After a successful change, the account will automatically enter a 24-hour security protection period, during which you cannot withdraw cryptocurrencies, withdraw fiat currency, or bind a new bank card. This is a common security mechanism for mainstream global exchanges, not a restriction aimed at individuals.
Update API Bindings
If you have previously created API keys for the account for quantitative trading, changing the phone number will not affect the use of the API, but it is recommended to re-check the IP whitelist settings of the API to avoid abnormal interception due to equipment changes.
Notify Trusted Contacts
After the change is complete, it is recommended to synchronously inform your emergency contacts of the new phone number. If the account has the emergency contact function enabled, some large-amount operations will be notified to them via SMS.
Frequently Asked Questions (FAQ)
Q1: Is there a fee to change the bound phone number?
It is completely free. Binance will not charge any fees for users changing their bound information. If someone asks you to pay a fee during the operation, it must be a scam, please stop the operation immediately.
Q2: Can the original phone number still be used to log in after the change?
No. After a successful replacement, the original phone number is completely unbound from the account, and can no longer receive verification codes or be used for logging in. So be sure to ensure the new phone number can be used normally before operating.
Q3: Can one phone number be bound to multiple Binance accounts?
No. Binance's rule is that each phone number can only be bound to one account. If you want to bind the old number to a new account, first unbind it in the old account. After unbinding, you need to wait 24 hours before using it on the new account.
Q4: What if I forgot my password when changing the binding?
First go through the password recovery process, and then change the phone number after resetting the password. The two processes cannot be performed at the same time, and must be operated in sequence. Password resets require email verification, which can generally be completed within 2 minutes.
Q5: What should I do if I keep failing to receive the verification code during the change process?
First check if the mobile phone signal is normal, and then confirm whether the country code before the phone number is selected correctly. If it is still not received, wait 60 seconds and click "Resend". After 5 consecutive failures, the account will be temporarily locked for 1 hour, and it is recommended to try again patiently after waiting.
