The WhatsApp username privacy feature, years in the making, is finally arriving for the app’s three billion account holders: from 29 June 2026, users can begin reserving a unique handle so they can connect with others without ever revealing their phone number.
The rollout begins with a reservation period, with usernames expected to become fully operational later in 2026, according to The Straits Times. Users will be notified when their username is activated. Reservations can only be made through the mobile app, not WhatsApp Web or Desktop.
How the WhatsApp Username Privacy Feature Actually Works
Usernames will be capped at 35 characters. Once activated, they allow two people to initiate contact without exchanging phone numbers. A small number of high-profile names (politicians, celebrities) will be reserved and unavailable to ordinary users.
For added protection against unwanted contact, WhatsApp is offering optional username keys: short numbered codes that, when added, mean someone needs both your username and its key to reach you. The company says its systems also detect and block abuse patterns.
The feature is not compulsory. Usernames can be removed or changed at any time, and there will be no public directory. A phone number remains required to hold a WhatsApp account at all.
According to TechCrunch, WhatsApp has been developing username functionality since at least 2023, and the reservation process was designed specifically to prevent duplicate handles across its user base.
Late to a Feature Its Rivals Have Had for Years
The timing invites an obvious observation. Telegram, Signal, and Wire have all offered username-based contact for several years, as TechCrunch notes. WhatsApp, with its vastly larger user base, is arriving at this point considerably later than its more privacy-focused competitors.
The comparison with Signal is instructive rather than flattering. When Signal launched its username feature in 2024, the company was explicit about what a username is and is not: it is not a profile name visible in chats, not a permanent handle, and not displayed to the people you are already messaging. It is simply a mechanism to initiate contact without disclosing a phone number. Signal still requires a phone number to sign up, as does WhatsApp.
WhatsApp’s implementation appears to follow a similar logic. The structural difference is the audience: Signal is a niche app for the privacy-conscious; WhatsApp is a global communication utility used by billions who may never have considered what their phone number reveals about them.
Catriona Veliz, a professor at Oxford University and author of Privacy is Power, offered a pointed qualification. ‘It is a good feature, but even if it does offer more privacy, remember WhatsApp is not a privacy-friendly app overall,’ she said. ‘It collects much metadata about users for marketing purposes. We have to remember that WhatsApp is owned by Meta, one of the tech companies with the worst track records when it comes to privacy.’
That last point deserves weight. WhatsApp does not read the content of private messages; end-to-end encryption prevents that. But the platform does use metadata (general location, basic account information such as age) to support advertising. Adding a username does not change that architecture.
For businesses, the change carries a specific operational consequence. According to CM.com, new inbound conversations from username-adopting users will arrive for businesses with only a Business-Scoped User ID rather than a phone number, altering how companies identify and manage contacts through the platform.
Creators, small businesses, and organisations will have the option to claim the same username they hold on Instagram or Facebook. Anyone else who wants consistency across Meta’s apps will need to link accounts through Accounts Centre, which means data is shared across services including Threads and Messenger.
The feature lands against a backdrop of leadership change. On 22 June 2026, CNBC reported that Kunal Shah, founder of Indian fintech company CRED, would take over as head of WhatsApp. Will Cathcart, who led the platform for seven years, wrote that he was stepping back because WhatsApp ‘is in the strongest position it’s ever been.’ Meta chief executive Mark Zuckerberg said Cathcart would move into a new role building products from the ground up.
Whether usernames represent a genuine privacy advance or a carefully managed concession to user pressure, the answer probably lies in what WhatsApp’s new leadership chooses to do next. The username is the easy part. The metadata is the harder conversation.
