WhatsApp is introducing a new privacy feature that will let users connect without revealing their phone numbers. The messaging platform has started rolling out username reservations ahead of a wider launch expected later this year. The update will allow users to claim a unique username in advance and use it to begin conversations instead of sharing their mobile number.
Announcing the feature in an official blog post on Monday, WhatsApp said the rollout will take place gradually over the coming months.
WhatsApp starts username reservations
The company has opened username reservations for eligible users so they can secure their preferred handle before the feature becomes available to everyone. According to WhatsApp, the early reservation process is important because the platform now has more than three billion users worldwide.

The feature will remain optional. Once fully rolled out, users who choose to enable it will be able to use their username when messaging someone for the first time instead of disclosing their phone number.
How to reserve a WhatsApp username
WhatsApp said users can check if the feature is available by updating the app to the latest version and navigating to Settings > Account > Username.
The company added that users will receive an in-app notification when the feature becomes available in their country.
If a chosen username is already taken, WhatsApp will offer a built-in username generator with alternative unique suggestions.
Privacy remains the main focus
Unlike many social media platforms, WhatsApp said it will not create a searchable username directory. Instead, users will only be able to contact someone if they already know that person's exact username.
According to the company, this design is intended to limit spam and unwanted messages while giving users more control over who can reach them.
WhatsApp is also introducing an optional username key that users can share separately for an added layer of protection. The company said this additional verification feature will help users decide who can initiate conversations using their username.

A boost for creators and businesses
The new username system is also aimed at creators, businesses and organisations that already have an established online identity.
WhatsApp said eligible users will be able to reserve the same username they use on Instagram or Facebook, making it easier to maintain consistent branding across Meta's platforms.
At the same time, WhatsApp clarified that usernames are completely optional. Users who prefer sharing their phone numbers can continue using the app as they always have.
The company also said there will be no public directory or recommendation system, ensuring usernames remain private unless users decide to share them. The phased rollout has already begun, and users will receive an in-app notification once the feature is available in their region.
