SMS verification is one of the fundamental security methods for Binance accounts and should be used alongside Google Authenticator. After registering on Binance, complete your security settings promptly.
Enabling SMS Verification
If you registered with a phone number, SMS verification is enabled by default. If you registered with email, you can manually bind a phone number:
- Go to "Security Settings"
- Find the "Phone Verification" option
- Select the country code and enter your phone number
- Receive and enter the SMS verification code
- Complete the binding
When SMS Verification Is Used
After binding your phone number, the following operations require an SMS verification code:
- Logging into your account
- Withdrawing cryptocurrency
- Modifying security settings
- Adding withdrawal whitelist addresses
- API management
Limitations of SMS Verification
While SMS verification is convenient, it's not the most secure method. SIM cards can be cloned or hijacked, and texts can potentially be intercepted. Therefore, it's recommended to also enable Google Authenticator for dual-layer protection.
Changing Your Phone Number
If you need to change your bound phone number:
- Go to Security Settings
- Tap "Change Phone Number"
- Verify your current phone number
- Enter and verify the new phone number
If you no longer have access to the old phone number, you'll need to contact Binance customer support for assistance, which may require additional identity verification.
Can't Receive Verification Codes
Confirm your phone number is correct and your signal is normal. If you still can't receive codes, try waiting a few minutes and requesting a resend. Some carriers may block international SMS -- contact your carrier to lift the block. Download the Binance APP to use push notifications as a supplementary verification method.
