WhatsApp will let users go by usernames instead of phone numbers, closing a longstanding privacy gap on the app used by more than three billion people.

The Meta-owned platform said on Monday that it has begun letting users reserve unique usernames before a wider rollout later this year when people will be able to choose to be found and contacted only by their handles.

WhatsApp said the change was designed as a core privacy feature with no public directory of usernames and no autocomplete suggestions, meaning users will need to know someone’s exact username to reach them for the first time.

WhatsApp offers end-to-end encrypted communication across smartphones, tablets and desktop computers. Until now, it has allowed users to be contacted by anyone who has their phone number.

The app said in a blog post that over the “coming months”, users will get the option to be found and contacted only by their username, and not their number. It wasn’t more specific about the timeline.

“We have designed this as a core privacy feature,” Alice Newton-Rex, WhatsApp’s vice president of product, told reporters.

“People will need to know your exact username to contact you for the first time,” she said.

WhatsApp’s current privacy settings are limited to blocking individual users and silencing unknown callers.

While people in the United States still prefer text messaging to WhatsApp, the app is widely used in Europe, Asia and much of the rest of the world.

Catchy online handles are highly coveted, and users will likely scramble to claim a desirable one.

“I think a lot of people will go and get usernames, and that’s why we decided to open reservations early,” Newton-Rex said.

Companies, organisations and creators with existing accounts on Meta’s social media platforms, Instagram and Facebook, will get the chance to claim their usernames on WhatsApp.

Usernames need to be three to 35 characters. To prevent impersonation, WhatsApp will hold back usernames for high-profile people or groups, such as celebrities, public figures and government entities.
