WhatsApp has begun a gradual rollout of a username feature that allows people to start conversations without sharing their phone numbers [1].
This shift addresses a long-standing privacy gap in the app's architecture. By decoupling identity from a mobile number, the platform reduces the amount of personal data users must disclose to strangers or professional acquaintances.
The rollout of usernames began in April 2026 [2]. The feature is being deployed to users on both Android and iOS devices worldwide [1].
Under the previous system, every user was required to share their phone number to initiate a chat or be added to a contact list. This requirement often served as a barrier for users who wished to maintain a separation between their private life and their digital communications. The new system allows users to create a unique identifier — a username — that serves as the primary point of contact.
Meta Platforms, the parent company of WhatsApp, designed the update to improve privacy and simplify how users maintain their accounts [1]. The gradual release ensures that the infrastructure can handle the transition as millions of users migrate to username-based identities.
While the rollout is ongoing, the feature is intended to bring WhatsApp closer to the functionality of other major messaging platforms that have long abandoned the phone-number-only requirement. Users can now manage their visibility and decide who has access to their actual mobile digits while still remaining reachable via the app [1].
“WhatsApp has begun a gradual rollout of a username feature that allows people to start conversations without sharing their phone numbers.”
This update marks a fundamental shift in WhatsApp's identity model, moving from a telephony-based system to a social-handle system. By removing the phone number as the sole identifier, Meta is reducing friction for user growth and addressing persistent privacy concerns regarding data harvesting and unsolicited contact.
