WhatsApp is rolling out a new Username feature that will let people start chats without sharing their mobile numbers. The company has already opened username reservations globally, and the rollout will expand gradually across countries over the coming months.

The feature is aimed at improving privacy and making it easier to connect with new people, such as classmates, neighbours, event contacts, or parents in school and sports groups. WhatsApp says the change is not meant to work like Instagram or X, because usernames will not be public or searchable in a directory.

How it works

Users will be able to create a unique username made up of 3 to 35 characters using lowercase letters, numbers, dots and underscores. Once set, the username can be changed or removed later if needed. New contacts will be able to message a user through the username instead of seeing the phone number.

WhatsApp says existing chats will not be affected. People who already have your number saved will continue to chat with you as before, while the phone number will still be required to create and use the account.

Privacy and safety

The company will not provide a public username search or suggestion system, so someone can contact you only if they know your exact username. WhatsApp is also introducing an optional Username Key, which adds an extra layer of security by requiring a special key before someone can start a first-time chat.

This extra step is designed to reduce spam and unwanted messages. Blocking, reporting and end-to-end encryption will remain unchanged under the new system.

For creators and businesses

WhatsApp says creators, businesses and organisations will be able to use the same username across WhatsApp, Instagram and Facebook wherever available. Some high-profile usernames tied to celebrities or major brands may be reserved to prevent impersonation.

For businesses, the feature could make customer communication easier without exposing personal contact details. For users, the biggest change is simple: new conversations may soon begin with a username instead of a phone number.
