WhatsApp Launches Username Feature: Reserve Your Handle Before Public Rollout
WhatsApp Usernames Are Here: What You Need to Know
WhatsApp has confirmed one of the biggest privacy overhauls in its history — usernames. Starting June 29, 2026, users worldwide can reserve a unique handle that will eventually replace the need to share a phone number when starting new conversations. The feature itself will roll out gradually over the coming months, but reservations are open now so users can lock in their preferred handle before demand peaks across WhatsApp's 3-billion-plus user base.
How Usernames Will Work
Once fully live, a user's phone number will stay completely hidden from new contacts, who will only see the chosen username instead. This is aimed at everyday situations — meeting someone at an event, joining a neighbourhood or community group, or connecting with a new classmate — where sharing a personal number can feel premature. Existing chats with saved contacts are not affected, and the feature remains entirely optional; anyone who prefers the traditional phone-number system can keep using WhatsApp exactly as before.
Username Format Rules
- Must be between 3 and 35 characters
- Only lowercase letters, numbers, periods, and underscores are allowed
- Must contain at least one letter (no numbers-only or symbols-only handles)
- Cannot start with "www." or end in a domain suffix like .com or .net
- Must be available across Meta platforms — Instagram, Facebook, and WhatsApp — to be claimed
No Public Search, Extra Security Layer
Unlike Telegram or Signal, WhatsApp usernames will not be searchable inside the app. Someone must know a person's exact username to start a chat with them. On top of that, WhatsApp is introducing an optional four-digit "username key" — a PIN-like code that new contacts must also enter before their first message goes through, effectively blocking unsolicited outreach from strangers who only know the handle.
Claiming Your Existing Instagram or Facebook Handle
Creators, small businesses, and organisations that already have a recognisable Instagram or Facebook username can claim the same handle on WhatsApp for consistent branding across Meta's apps. To reserve a username, users can head to Settings > Account > Username (or via the Profile section) on the latest version of the app, where a built-in username generator can also suggest available handles.
India Among the First Test Markets
WhatsApp began a limited beta of the feature back in April 2026, with Indian beta users among the earliest to get access. The global rollout is being executed in phases across Android, iOS, Windows, and Web, meaning availability will vary by account and country over the coming months rather than arriving for everyone at once.
What It Means for Businesses
For businesses using the WhatsApp Business API, the change goes deeper than a cosmetic handle. WhatsApp is introducing a "business-scoped user ID" (BSUID) that will work alongside or in place of phone numbers inside APIs, webhooks, and CRM systems. Companies have been told to update their integrations, chatbots, and customer-support tooling ahead of a mid-2026 technical deadline, since phone numbers will no longer be the only way to identify a user in chats or system logs. Business accounts themselves will still display their phone number, but will also get a unique, searchable username to aid discoverability.
Why Now
Rival messaging apps such as Telegram, Signal, and Wire have offered username-based identity for years, and the move also comes as WhatsApp leadership has recently changed. A senior WhatsApp product executive said the update reflects how sharing a personal phone number with someone new — a neighbour, classmate, or event acquaintance — can feel like an unnecessarily big step, given how much of a person's life is tied to that number.
Conclusion
WhatsApp usernames mark a fundamental shift away from phone-number-based identity toward a more private, handle-based way of connecting — something users have requested for years. With reservations open immediately and the full feature landing later in 2026, both individual users and businesses have a window now to secure their preferred handle and prepare their systems before the wider rollout begins.
