The Current Complexity of Registering for Zalo 

However, registering on Zalo is no easy task for foreigner. The platform security system regularly identifies and limits accounts.

1. The Foreign Number Block (Error 2028)

When registering a Zalo account with foreign phone numbers (such as US, UK, European numbers), it is very likely that you will encounter Error 2028:"Device not accept". Zalo heavily favors domestic users. For a successful registration, you are required to use a Vietnam (+84) phone number.
