Overview
- WhatsApp has started enabling the feature for a small group of Android and iOS users, with an editable username field showing up in profile settings for those selected.
- Usernames must be 3 to 35 characters, include at least one letter, and use only lowercase letters, numbers, periods, and underscores, with domain‑style names barred.
- Handles must be unique across Meta apps, and reusing one from Instagram or Facebook requires proof of ownership through the Accounts Center, which can link identities across services.
- An optional four‑digit Username Key can be set so only people who know both the name and the code can start a first chat, a safeguard meant to reduce spam and stalking.
- WhatsApp has not given a date for broader availability and has not issued a formal statement, and reporting indicates a phone number will still be needed to create or manage an account.
