Taiwan's 111 government SMS is a dedicated short-code for official messages, so citizens can instantly verify what is real — a blue checkmark for public communication. Every message shows the agency's name and the last three digits of your phone number: proof that the sender knows who you are and the network guarantees who they are. When people trust the channel, phishing and impersonation lose steam. Every country needs its own version — a low-friction, verifiable trust channel that works even in crisis.
