WhatsApp Usernames: Share a Name, Not Your Phone Number
By Jeremy ·
WhatsApp is opening username reservations this week, ahead of a full feature launch later in 2026. The appeal is straightforward: once usernames roll out, you can share a username with a new contact instead of your phone number.
How to reserve your username
Reserving takes a few seconds. Open the latest version of WhatsApp, go to Settings > Account > Username, and pick one. The feature won't go live everywhere at once - WhatsApp says it'll roll out gradually over the coming months and notify users in-app when it reaches their country.
With over three billion people on the platform, a lot of names overlap. That's why reservations are open before the feature launches - so there's a fair window to claim the name you actually want. If nothing comes to mind, WhatsApp has a built-in generator.
What changes when usernames go live
There's no public directory. Someone needs to know your exact username to find you - no search suggestions, no browsing. WhatsApp has also added an optional "username key," a secondary code others need before they can message you for the first time. You can use one or both layers depending on how much filtering you want.
The bigger shift: when you message someone new, they won't see your phone number if you've enabled your username. For most of WhatsApp's history, starting a conversation meant the other person automatically had your digits the moment you showed up in their chat. That changes.
The practical use cases are specific. Joining a group chat - a parent group for a sports team, a neighborhood group, a community for an event you attended - used to mean everyone in that group could see your number. A username removes that. You're in the conversation, but your number isn't visible to people you've never met.
The same logic applies one-on-one. Sharing a username with someone new is a lower-commitment first step than handing over your number directly.
Creators and businesses
WhatsApp has reserved a separate path for creators, small businesses, and organizations that want a consistent presence. They can claim their existing Instagram or Facebook username on WhatsApp, keeping their identity aligned across platforms.
What it doesn't change
A phone number is still required to create a WhatsApp account. That hasn't changed.
The feature is also narrower in scope than it might look. Carisa Veliz, a professor at Oxford University and author of Privacy is Power, put it directly: "It is a good feature, but even if it does offer more privacy, remember WhatsApp is not a privacy-friendly app overall. 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."
Username privacy is contact-layer privacy. It controls who can reach you and who sees your number. It doesn't change what Meta sees once you're in a conversation, and it doesn't alter how your data is handled on the backend. Those are different questions from whether a stranger in a group chat can see your digits. Worth using for what it is.
WhatsApp is also under new leadership. Kunal Shah, founder of Indian fintech company CRED, is taking over as head of the platform after Will Cathcart steps down following seven years in the role.
