Can't receive SMS codes when you need them? Don't panic — there are solutions. sign up for Binance with multiple verification methods set up, and download the Binance APP to enable Google Authenticator as backup.
Common Causes
Signal Issues
Poor signal in basements, elevators, or weak coverage areas.
SMS Blocked
Security apps or built-in spam filters may block Binance messages.
Number Format Wrong
Wrong country code or incorrect number during binding.
Carrier Restrictions
Some carriers block international SMS. Binance may send from overseas numbers.
Rate Limiting
Requesting too many codes in quick succession triggers rate limits.
Solutions
Method 1: Check Phone Settings
- Verify signal strength
- Check SMS blocking/spam filters
- Ensure SMS storage isn't full
- Restart phone and retry
Method 2: Contact Your Carrier
Ask them to enable international SMS reception if it's been blocked.
Method 3: Switch Verification Method
In Binance security settings, use:
- Email verification codes
- Google Authenticator (recommended — no network required)

Method 4: Voice Verification
Some prompts offer a "voice code" option — a call delivers the code verbally.
Why Google Authenticator Is Better
- No network dependency
- Can't be blocked by spam filters
- Codes refresh every 30 seconds
- Higher security than SMS
Last Resort
If nothing works:
- Try changing your bound phone number
