Why Does Zalo Require a Vietnamese Phone Number?

Zalo was built for users in Vietnam — and a +84 number is how the platform verifies that users are part of its intended market:

  • Domestic market control — Zalo was built for users in Vietnam, and a +84 number confirms that the user belongs to the intended target market.
  • Preventing bot and spam accounts — limiting registration to domestic numbers helps reduce fake accounts from abroad and abuse of the system.
  • Compliance with local regulations — messaging apps in Vietnam must comply with regulations related to user identification through phone numbers.
  • Secure account recovery — password resets and security notifications are sent through the verified phone number.
