Three Billion Users, One Week to Grab Your Name: WhatsApp Has Opened Username Reservations — Here Is Everything You Need to Know

The Feature That Should Have Existed Years Ago

When someone new walks into your life — a classmate, a neighbour, someone you meet at an event — sharing a phone number can feel like a big step. That is because a phone number is personal and tied to so many parts of your life. Sometimes you just want to chat without handing over your digits. That is WhatsApp's own framing of the problem its newest feature is designed to solve — and it is a problem that 3.2 billion people have been quietly tolerating since the app's launch in 2009, even as competitors built their privacy architecture differently from the start.

Starting Monday, 29 June 2026, WhatsApp's three billion users can pick a unique username — a move aimed at boosting privacy by enabling connections without exchanging phone numbers, according to Meta Platforms Inc., the app's owner. The company stated that reservations are open now, with full functionality slated for later in 2026.

Why Reservations Are Opening Before the Feature Itself

Meta said it is opening reservations early because WhatsApp now serves more than three billion users, increasing the likelihood that many people will compete for the same names. The logic is straightforward: if you wait until username messaging actually works before allowing people to claim handles, the most desirable names will be gone within minutes. With more than 3 billion users on the platform, plenty of desirable names are likely to get scooped up fast.

Alice Newton-Rex, WhatsApp's product development lead, said the feature lets users control who can view their phone number, especially when meeting new people or participating in group chats. Meta characterised the update as a major privacy improvement.

How to Reserve Your Username Right Now

To claim a username, go to Settings, Account and then Username. You can choose your own, and you'll be able to reserve it as long as it's unique, but you can also use the in-app generator. The reservation phase is rolling out globally right now. However, you might not see the option in your app immediately. Meta is releasing the update gradually over the coming months to ensure a smooth launch. You will receive an in-app notification when the reservation system reaches your country.

Usernames need to be between three and 35 characters, and going forward, they'll need to stick to lowercase letters, numbers, periods, and underscores, with at least one letter required. Handles can't start with "www" or end in something that looks like a website domain, a rule meant to stop people from disguising a username as an official link.

The Username Key: A Second Layer of Control

Beyond the username itself, WhatsApp is also introducing something called a "username key." This acts as an extra layer of defence against unwanted messages. If you enable this optional feature, a username alone is not enough to reach you. A new contact must also know your specific key to start a chat. Think of it like a secret PIN code you give to new friends. During the reservation phase, this key is a simple four-digit number. When the feature officially goes live, it will upgrade to a stronger alphanumeric code. You can also reset this key at any time to instantly block new inbound contacts.

No Directory, No Search, No Spam Risk

WhatsApp said there would be no searchable username directory or automated suggestions. People will need to know a user's exact username to initiate contact, while an optional security key will provide further control over who can send messages. This deliberate design choice distinguishes WhatsApp's implementation from social media platforms where username discovery is part of the core product — the absence of search means the system is specifically designed for selective, intentional sharing rather than open discoverability.

Creators, Businesses and the Cross-Platform Claims System

In addition to allowing users to create unique usernames that don't necessarily match their handles on other social apps, WhatsApp has set up a claims system for creators, small businesses, and organisations looking to maintain a consistent online presence. It will allow these accounts to claim the same username they already use on Instagram or Facebook.

To curb impersonation and fraud, during the reservation period WhatsApp has temporarily set aside the usernames already held on Facebook and Instagram for those account holders. Additionally, the platform will permanently block certain high-profile usernames associated with public figures, celebrities, and government bodies to prevent misuse by impostors.

Businesses using the WhatsApp Business API have been told to update their systems to support a new business-linked ID by around mid-2026, since phone numbers will no longer be the only way to identify a user in chats or backend systems once usernames are in wider use.

What Changes — and What Does Not

When usernames become available, users who enable the feature can communicate with new contacts without exposing their phone numbers. The feature could also simplify participation in group conversations. Meta cited examples such as joining neighbourhood chats or school sports groups, where users may prefer not to immediately disclose their personal phone numbers to everyone in the group.

Username reservations are optional, and users who do not reserve one can continue using WhatsApp with their phone number as they do today. Likewise, existing contacts who already have the user's phone number will continue to communicate normally.

This update is about who can start a conversation with you, not about how WhatsApp handles the content of your messages once you're chatting. The app's end-to-end encryption setup, and separate questions around how reported messages get reviewed, remain a completely different conversation and aren't affected by this change at all.

Even after usernames go live, phone numbers won't disappear from WhatsApp entirely. You'll still need one to create an account in the first place.

The Competitive Context: WhatsApp Arrives Late to a Party Telegram Started in 2013

Usernames aren't a new idea in messaging. Apps like Telegram, Signal, and Wire have offered this kind of number-free identity for years, letting people connect without exposing personal contact details. Signal introduced usernames in 2024, allowing users to hide their phone numbers from new contacts while requiring the exact username to initiate conversations. Telegram showed up to this party back in 2013.

The difference, of course, is scale. Telegram has roughly 900 million users. Signal's user base is measured in the tens of millions. WhatsApp's product development lead Newton-Rex said: "We think it will be successful if you have another way to feel safe on WhatsApp, to feel like you can keep your phone number private and you can feel confident to connect with new people if you want to." When three billion people gain that option, the practical impact on how human beings share personal information in everyday social and professional contexts is likely to be considerably larger than when a few hundred million do.
