WhatsApp Introduces Usernames, Ending the Need to Share Phone Numbers

WhatsApp is rolling out one of its biggest privacy changes yet. The Meta-owned platform announced on Monday, June 29, 2026, that users can now reserve usernames ahead of the feature’s wider launch later this year. Meta says more than 3 billion people across 180 countries use WhatsApp’s messaging and video-calling platform. This marks a fundamental shift away from phone numbers as the app’s core identity layer, bringing WhatsApp closer to how Signal and Telegram already work.

Why WhatsApp Is Opening Reservations Early

Username overlap was the deciding factor behind this early rollout. “With over three billion people on WhatsApp, a lot of names overlap, which is why we’re opening reservations early so everyone has the opportunity to select the username that matters to them,” the company said. 

To reserve a username now, users go to Settings, Account, then Username after updating to the latest app version. Early reservation guarantees first-choice access before the feature fully activates worldwide later this year.

How the Privacy Feature Actually Works

Once active, usernames replace phone numbers for new contacts entirely. Users who set a username will be able to start conversations without revealing their phone number to new contacts or businesses.

There is no public directory and no suggestion algorithm, meaning someone must know a user’s exact username to make contact. Users can also set an optional key that others need before messaging them via the new username.

Username Rules and Restrictions

• Usernames must contain between 3 and 35 characters, with at least one letter
• Only lowercase letters, numbers, periods, and underscores are allowed
• Usernames cannot begin with “www.” or end with domains like “.com” or “.net”
• Some usernames are reserved for governments, public figures, and businesses 

How This Compares to Signal’s Existing System

WhatsApp isn’t first to this privacy model; it’s catching up. The Signal encrypted messaging service has allowed users to choose a custom username since February 2024, following a public test phase that began in November 2023. WhatsApp’s three-billion-user scale, however, makes this rollout far larger in real-world impact than Signal’s smaller user base ever achieved.

Meta Stock and Related Names to Watch

WhatsApp’s privacy overhaul lands inside a broader competitive messaging landscape. Investors tracking the space should watch these related companies:

• Meta Platforms (NASDAQ: META), parent company of WhatsApp, Instagram, and Facebook
• Telegram Group (private) competing messaging app with established username system
• Signal Foundation (nonprofit) pioneer of the username-based privacy model WhatsApp is now adopting

WhatsApp’s username rollout, beginning June 29, 2026, signals Meta’s clearest move yet toward decoupling user identity from phone numbers a shift years in the making for its 3-billion-strong global user base.
