WhatsApp has launched the Username feature for Android and iOS users, opening reservations before the full system goes live later this year. The latest version of the app, available on both platforms, is the compatible update, confirmed through WhatsApp’s official announcement. Users can claim a handle in seconds from the app settings. This applies to everyone on WhatsApp, not just beta testers, and follows the same week that Cloud API business partners gained their own username reservation option.
Why WhatsApp Is Opening Username Reservations Now
WhatsApp has more than three billion users, so a lot of preferred handles are going to overlap once the full username system goes live. Opening reservations early gives people the chance to secure the name they want before someone else takes it.
Usernames add a privacy layer WhatsApp has never had before. Once the full feature launches, people can message someone new without sharing their phone number. WhatsApp still requires a phone number to sign up and log in, but messaging itself is getting an upgrade for anyone who wants to keep that number private.
How to Reserve a Username on WhatsApp for Android and iOS
Reserving a username takes only a few seconds on the latest version of WhatsApp. Users open the app settings, tap Account, then tap Username.
From there, they can type the handle they want, as long as it meets WhatsApp’s formatting rules and is still available. Anyone unsure what to pick can use WhatsApp’s built in generator, which suggests options based on what a user types in.
Claiming Your Existing Instagram or Facebook Username
Creators, businesses, and organizations often want their WhatsApp presence to match what people already know them by elsewhere. WhatsApp lets users claim the same username they already use on Instagram or Facebook, as long as they can prove ownership.
To do this, users need to add their account to Accounts Center, which confirms they are the rightful owner of that handle on those platforms. Anyone who only wants a unique username just for WhatsApp does not need to touch Accounts Center at all.
What the Username Key Does and When to Use It
WhatsApp is also introducing an optional username key alongside the reservation feature. Without a username key turned on, anyone who knows a person’s exact username can start a conversation with them directly.
Turning on a username key adds an extra layer of control, since the username alone is no longer enough to reach someone. People who already have a phone number saved never need to know the username key at all. Anyone who claimed a well known handle from Instagram or Facebook, or who already has a public following under that name, should consider turning this on, since their username is easier for strangers to guess or find.
What Changes Once WhatsApp Launches Usernames
Once the full username feature goes live, messaging someone new for the first time will look different for anyone who has a username set up. New contacts will only see the username, not the phone number, unless they already had that number saved.
This mainly changes the first message with a new person or business, since that moment is usually when a phone number gets shared today. For anyone who wants to keep their number private going forward, this changes a lot about how WhatsApp can be used day to day.
Business Partners Are Reserving Usernames Too
The same week WhatsApp opened reservations to regular users, it extended the same option to Cloud API business partners. These partners can now reserve and claim a username through WhatsApp Manager, Meta Business Suite, or the Username API.
WhatsApp also introduced two related tools for businesses during this rollout, Send to BSUID and a Phone Number Request call to action button, both designed to help businesses reach customers who choose to use a username instead of sharing their phone number.
Platform Availability for Android and iOS
Username reservation is available now on the latest version of WhatsApp for both Android and iOS. There is no separate beta requirement, since this is a stable feature rolling out to the general user base.
The rollout is gradual by region, so not everyone sees the option on the same day. WhatsApp has said it will notify users directly inside the app once reservation becomes available in their country, and the full username feature that actually works in chats is expected to follow later in 2026.
Conclusion
WhatsApp is treating this reservation phase as the first step toward a much larger privacy shift, one that eventually lets billions of people message without exposing their phone number. The AllBetaInfo team will continue tracking how quickly reservation reaches new regions and when the full username system goes live.
Anyone with a recognizable name, brand, or existing Instagram or Facebook handle has the clearest reason to reserve now rather than wait.
