Meta explained that users will only be reachable if someone knows their exact username, adding that there will be no public directory or search suggestions for discovering accounts.
Global messaging app, WhatsApp, has announced a major privacy update that will allow users to connect with others without revealing their phone numbers, as the messaging platform prepares to introduce unique usernames globally.
The Meta-owned messaging service disclosed on Monday that users will soon be able to create personalized usernames that can be shared instead of their mobile numbers when initiating conversations. 
According to the company, the new feature is aimed at strengthening user privacy by preventing phone numbers from being automatically exposed in situations such as joining large group chats or contacting a business or individual for the first time.
Meta explained that users will only be reachable if someone knows their exact username, adding that there will be no public directory or search suggestions for discovering accounts.
The company said the approach is intended to reduce unwanted contact while giving users greater control over who can reach them.
With more than three billion people using WhatsApp worldwide, Meta acknowledged that not every preferred username will be available because each handle must be unique.
The company said the rollout of username reservations will begin gradually over the coming months, with users receiving notifications when the feature becomes available in their respective countries.
Meta also announced that creators, organisations and small businesses will be given priority to secure usernames that match those they already use on Facebook or Instagram, helping them maintain consistent identities across the company’s platforms.
