Overview
- Android beta version 2.25.28.12 shows a Reserve username option detected by WABetaInfo, though the capability is not broadly available.
- Reserved names must be unique and follow rules: 3–30 characters, at least one lowercase letter, letters/digits/dots/underscores only, no “www.” prefix or domain endings.
- WhatsApp intends to open reservation access to a wider group before full rollout to avoid popular names being locked by early testers.
- An optional PIN for first-time contacts means knowing a username alone will not allow someone to send a message.
- No release date has been announced, and reports indicate phone numbers may still be required for tasks such as account registration.
