What changed

Users can now reserve a unique username (preceded by @) via Settings > Account > Username. The reservation period opened on June 29, 2026, with full functionality expected by year end.

Anti-abuse and brand protection

WhatsApp has pre-reserved usernames for brands, celebrities, and public figures to prevent impersonation.

Rollout and availability

The rollout is gradual across countries. Users are encouraged to reserve their preferred username early due to high demand. Source: lavozar The feature is expected to be fully operational by late 2026.
