WhatsApp has begun reserving usernames for a limited group of users ahead of a global rollout expected later in 2026, introducing a new way to connect without sharing phone numbers. This feature, which is compatible with Android, iOS, and web platforms, allows individuals and businesses to create a unique handle of 3 to 35 characters that remains optional, letting users who prefer traditional methods continue using phone numbers. By concealing mobile numbers during initial conversations, the update significantly enhances privacy and control over personal data, addressing long-standing concerns similar to features already available on Telegram and Instagram. The system requires usernames to be available across Meta platforms and includes an optional verification code for added security, with testing starting in the second half of 2026 before a wider release in 2027.
