In late June 2026, Meta officially launched one of the most significant privacy overhauls in WhatsApp's history, the ability to communicate using unique usernames rather than phone numbers. For a platform serving over three billion users globally, this is an architectural shift that fundamentally changes how people identify themselves on the world's most popular messaging service. At present, the feature is optional, meaning users who prefer the traditional phone number-based system can continue using WhatsApp as before. The feature will be rolled out gradually over the coming months and users will be notified when their username functionality is activated.
The WhatsApp username replaces the need to share a personal phone number when initiating new conversations. Once enabled, a user's phone number remains entirely hidden from new contacts, they will only see the username.
