WhatsApp is moving beyond phone-number-only discovery with the rollout of username reservations, giving users a new way to secure a handle before usernames become available for full use later this year. The update, announced on June 29, marks one of the app’s most important privacy changes in years because it changes how new contacts may find and message each other on a platform that has traditionally depended on mobile numbers.
A Major Privacy Shift
For years, WhatsApp’s biggest strength was also one of its clearest privacy trade-offs. The app made messaging simple by tying every account to a phone number, but that also meant a number often had to be shared before a conversation could begin. That model worked well for friends, family and saved contacts, but it became less comfortable in newer use cases such as community groups, school chats, marketplace interactions, events, customer support and one-time conversations.
WhatsApp is now trying to close that gap with usernames. In its announcement, the company said sharing a phone number “can feel like a big step,” especially when users are connecting with people they do not know well. The new system is designed to let users decide when a number should remain private and when a username is enough.
Alice Newton-Rex, WhatsApp’s vice president of product, described the change as a privacy-first feature. “People will need to know your exact username to contact you for the first time,” she said, making it clear that the feature is not being built like a public social directory.
How Reservations Work
The reservation phase is meant to prevent a rush when usernames fully launch. WhatsApp says more than three billion people use the app, which means common names, brand names and short handles could overlap quickly. By opening reservations early, the company is giving individuals, creators, organizations and small businesses time to secure names before the feature becomes widely active.
To check availability, users need to update WhatsApp to the latest version. On Android, the option appears under Settings, then Account, then Username. On iOS, users may find it through the You tab, then profile, then Create Username, depending on whether the rollout has reached their account. If the option is not visible yet, WhatsApp says users will be notified inside the app when reservations are available in their country.
The username feature is optional. Users can reserve a handle, change it later or remove it if they decide they do not want to use usernames. They can also keep using WhatsApp through their phone number as before.
What Changes for Users
Once usernames go live, a person messaging someone for the first time through a username will not automatically expose their phone number if the username feature is enabled. WhatsApp says that when users message a person or business for the first time, the recipient will “no longer see your phone number” if usernames are enabled.
That is the practical change WhatsApp is focusing on. It does not remove phone numbers from the platform entirely, and it does not instantly hide numbers from everyone who already has them. If a phone number has already been shared with existing contacts or group members, those people may still be able to see it. The privacy benefit mainly applies to new interactions going forward.
There is also no searchable directory of usernames. Unlike some social platforms, users cannot browse WhatsApp handles or search through suggestions to find people. A new contact will need the exact username before sending the first message.
Username Key Adds Protection
WhatsApp is also adding an optional username key, a privacy control designed for users who want another barrier before strangers can message them. The feature means someone may need both the username and the key before they can start a conversation.
This could be useful for people whose handle becomes visible outside a small circle. A creator, teacher, freelancer, community manager or business owner may want a public-facing username but still limit who can directly reach them. The username key gives users another way to decide how open that handle should be.
The company has not positioned usernames as a social networking feature. Instead, the rollout appears closer to privacy-focused messaging systems where users can be contacted without handing out personal numbers. Newton-Rex also compared the idea with Signal’s username system, saying it will work in a similar way.
Brands Get Early Priority
Meta is also trying to avoid impersonation problems before usernames open more widely. Businesses, creators and organizations will have the option to claim usernames that match existing Instagram or Facebook handles, as long as the handle is available and eligible.
WhatsApp is also holding back high-profile names linked to celebrities, politicians, government entities and public figures so those handles cannot be taken by unrelated users. That protection is important because usernames can quickly become identity markers, especially for brands and public-facing accounts that already use the same handle across Meta’s other platforms.
For small businesses, the change could become practical beyond branding. A WhatsApp username may eventually make it easier to print, share and remember a contact identity without exposing a phone number. However, businesses that rely on WhatsApp for customer messaging will need to watch how the final rollout affects contact flows, customer support systems, CRM tools and account discovery.
Rollout Will Take Time
The feature is not arriving for every user at once. WhatsApp says username reservations are beginning this week and will roll out gradually over the coming months. The full ability to use usernames for messaging is expected later this year, but the company has not given a single global launch date.
Newton-Rex said the early reservation window was opened because many users are likely to move quickly for preferred handles. “I think a lot of people will go and get usernames,” she said, adding that this was why reservations were opened early.
For everyday users, the advice is simple: update the app, check whether the username option is available and reserve a handle early if there is a name they care about. The rollout may look small at first, but for a service built around phone numbers since its beginning, usernames mark a major change in how WhatsApp wants people to connect.
