WhatsApp Introduces Username System Allowing Users to Chat Without Sharing Phone Numbers
WhatsApp has begun rolling out one of its biggest privacy upgrades in years — a username system that lets users contact each other without having to share their phone numbers. This is a big change in how the platform identifies users. It moves away from using phone numbers to a more flexible and privacy-friendly system. The reports suggest users can reserve unique usernames ahead of a broader global launch later in 2026, signalling the early stages of a major platform redesign.
Users won't need to give away personal contact details to start chats with the update. Instead, users can sign in with a unique username, a system already used on platforms including Telegram and Signal, rather than sharing phone numbers. Meta, which owns WhatsApp, is rolling out the feature as part of a wider effort to enhance privacy controls without damaging the app’s large global user base of more than 3 billion. It will be rolled out in phases and reservation systems have already been switched on in some areas.
How Does The Username Reservation Work?
There is a way for users to reserve their handle of choice before the feature is fully rolled out as part of the rollout. According to reports, users will be able to choose usernames in the app’s settings menu, with availability determined by rules for worldwide uniqueness. In many cases, users will also be able to link their WhatsApp username to their existing Instagram or Facebook identities, providing consistency across Meta’s ecosystem.
We pre-reserve certain high profile usernames, especially those linked to public figures, brands and organisations in order to prevent impersonation and abuse. WhatsApp is also reportedly adding protections like optional “username keys” or other verification methods that would limit unwanted messages even if a username was public. It’s designed to provide the privacy you’re used to on WhatsApp today, but with greater flexibility around how you connect.
The Market for Messaging Apps and Privacy Change
The move to usernames is a big shift away from the core identity model of WhatsApp, which has always used phone numbers as the main identifier for users. Phone numbers will still be required to create an account but not to be shared in communications, which means personal data shared in group chats, business and new relationships will be much less exposed.
Industry analysts say the move is a response to long-standing privacy concerns and increasing competition from messaging platforms already offering username-based communication. Apps like Telegram and Signal have made it the norm to use handles instead of phone numbers, especially for users who care about anonymity and digital security. The WhatsApp decision moves it closer to these models, while trying to preserve its usability and its global network effects.
The change will likely affect businesses and creators who use WhatsApp to engage with customers. But separating identity from phone numbers could mean improved outreach and less spam exposure, but also new moderation and verification issues. As the rollout continues, the feature is set to change how users establish their identity and trust in the world’s most popular messaging app.
