WhatsApp is beginning to roll out reservations for user-selected WhatsApp usernames worldwide, ahead of a wider feature launch later this year. The change replaces phone-number-based messaging for first-time contacts, letting users share a unique username instead of their registered phone number. Multiple outlets report that Meta is enabling reservations first, and once the feature is live, users can send and receive messages using their chosen username from day one.
Sources agree that WhatsApp is not yet fully enabling username messaging everywhere; reservations are available in regions where users see an in-app notification. The process involves going to the user’s profile, then Account, then Username, and choosing “Create Username,” followed by entering a handle that meets WhatsApp’s requirements and saving it. WhatsApp states usernames are 3 to 35 characters and do not need to match Facebook or Instagram usernames.
Several articles also highlight privacy-related design choices, including that there is no public directory of usernames and no suggestions, meaning people must know the exact username to contact someone initially. One report notes scrutiny in India regarding fraud risks tied to the broader username rollout.
