WhatsApp users will soon have a new way to call without revealing their phone numbers. Ahead of a broader update planned for later this year, the messaging platform has begun rolling out username reservations, allowing people to claim a unique ID before the feature becomes widely available.

The move represents one of WhatsApp’s biggest privacy-focused changes, giving users the option to start conversations using a username instead of sharing their mobile number. The company announced this feature in an official blog post on Monday, saying that the rollout will happen gradually over the coming months, according to WhatsApp.
Users can reserve usernames
WhatsApp has started allowing users to reserve a username in advance so that they have a better chance of securing the ID they want. The company said that this early reservation process is necessary because the platform now includes more than three billion users around the world.

The feature is optional and will eventually allow users to replace their phone number with a username when messaging someone for the first time, provided the option is enabled.
How to reserve a WhatsApp username
According to WhatsApp, users can check if the feature is available by updating the app to its latest version and going to Settings > Account > Username.

The company said that users will receive an in-app notification once the feature is available in their country.
If a preferred username is already used, WhatsApp will provide a built-in username generator that suggests alternative unique handles.
Focus on privacy and reducing spam
Unlike many social media platforms, WhatsApp said it will not offer a searchable username directory. Instead, people will only be able to contact someone if they already know the exact username.
The company said this approach is designed to reduce spam and unwanted messages while giving users greater control over who can reach them.

WhatsApp also offers an optional username key, which users can share separately for an extra layer of protection. According to the company, this additional verification will help users limit who can start conversations using their username.
The feature is also intended to help creators and businesses
The new system is also intended to benefit creators, companies and organizations that already have an established online identity.
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 platforms, WhatsApp said.
WhatsApp has made it clear that usernames are completely optional. Users who prefer to share their phone numbers can continue to use the app as they do now.
The company also said there will be no public directory or recommendation system, ensuring usernames remain private unless users choose to share them.
The rollout has already begun in phases, and availability will expand over the coming months. Users will receive an in-app notification once the feature arrives in their area.
