When registering on Binance, you choose between email and phone number. Register on Binance to see both options. Download the Binance app for in-app registration.
Email Advantages
More stable, especially with international providers like Gmail/Outlook. Won't become invalid when changing phone numbers. Lets you use your phone number as a secondary verification.
Phone Number Advantages
Faster — SMS codes arrive in seconds. More intuitive for those who rarely use email. Chinese numbers (+86) are supported.
My Recommendation
Use Gmail or Outlook email for registration, then add phone number as secondary verification. This gives both stability and dual protection.
Regardless of method, immediately enable Google Authenticator after registration — it's the most reliable account protection. Set up anti-phishing code too.
