First Identify the Code Type
Binance may ask for SMS, email or authenticator app codes. Each has a different fix.
SMS Code Not Received
- Check country code and phone number.
- Check SMS filtering and blocked messages.
- Do not request too many codes too quickly.
- Try again later or use email login if available.
Email Code Not Received
- Check spam and promotions folders.
- Search for Binance or verification.
- Whitelist official sender addresses.
Authenticator Code Is Wrong
The most common reason is phone time mismatch. Set your phone time to automatic and avoid entering a code when it is about to expire.
