WhatsApp Lets You Reserve a Username to Replace Your Phone Number
Three billion users can now claim a handle. Once the feature goes live, new contacts reach you by username - your number stays hidden.
WhatsApp usernames are coming, and reservations opened this week. WhatsApp's VP of Product Alice Newton-Rex announced the feature on June 29, confirming that users on the app's 3 billion-strong platform can now go to Settings → Account → Username to claim a handle ahead of a full launch later this year. Once live, new contacts will reach you through your username alone - your phone number stays off the table. Meta appointed new WhatsApp head Kunal Shah in a $900 million deal earlier this month, and this announcement is the first major product move under his watch.
Your Username Key Is a Second Factor - Not Just a Label
WhatsApp usernames don't work the way Instagram or X handles do. Knowing someone's username isn't enough to message them. WhatsApp built an optional "username key" alongside the handle itself - a four-digit code during the reservation phase, upgraded to alphanumeric when the feature goes fully live. Anyone who wants to contact you for the first time needs both your username and your key.
"People will need to know your exact username to contact you for the first time," Newton-Rex told reporters. No directory exists on WhatsApp for username lookup, and the app won't autocomplete handles as you type. That two-step design is probably smarter than a simple public handle system, since it means username discovery alone can't flood your inbox.
WhatsApp's Current Privacy Tools Leave a Visible Gap
Until now, WhatsApp users could block individual contacts, silence unknown callers, and set a profile name that only appears in group chats for people who don't have their number saved. None of those tools stop someone with your phone number from messaging you directly. Usernames close that gap by making the number invisible to new contacts entirely - you share a handle, not a digit string.
Signal Built This in 2024. WhatsApp Has 75 Times the Users.
Signal introduced username-based contact in 2024, letting its privacy-focused base hide phone numbers from other users. WhatsApp follows about 18 months later - but Signal has roughly 40 million active users and WhatsApp has 3 billion. A privacy pattern that was previously a niche choice for security-conscious users is now arriving at mainstream scale.
Companies, creators, and organizations can claim their existing Instagram or Facebook username during the reservation window. WhatsApp will protect high-profile accounts - celebrities, public figures, government entities - from username squatting. Usernames must be three to 35 characters and can include lowercase letters, numbers, periods, and underscores.
WhatsApp has not given a specific launch date for when usernames go live. Reservations roll out globally, with the app sending country-by-country notifications as access opens.
