WhatsApp has started rolling out username reservations to users worldwide, giving people the chance to lock in a unique handle before the feature goes fully live later this year. With more than 3 billion users on the platform, the company opened reservations ahead of the full launch because demand for common names will far outpace supply.
The option appears in Settings > Account > Username, and users will receive an in-app notification when the reservation screen becomes available to them. The rollout is gradual, so not every account will see it at the same time, and the full WhatsApp username feature itself will continue rolling out by country over the coming months.
Usernames on WhatsApp are entirely optional, but the privacy benefit is meaningful. Right now, sharing your WhatsApp contact details means sharing your phone number. A username gives you an alternative identifier, so people can reach you without ever seeing your number. WhatsApp has confirmed there will be no browsable directory and no recommendation system, meaning someone will need to know your exact username to initiate contact. That is a deliberate privacy decision, not an oversight.
There is also an optional username key feature currently in testing. If you enable it, anyone trying to message or call you for the first time will need to enter a code tied to your username before they can get through. It functions as a second layer of access control and only applies to first-time contact, so existing conversations are unaffected.
Username-based calling is also in development, which would let users place voice and video calls without knowing the recipient’s phone number at all. WhatsApp is also building a username availability checker for the web client, so users can verify handles directly from their profile page.
Username Format Rules and How to Reserve Yours
Usernames must follow a specific format. The rules are:
- Lowercase letters, numbers, underscores, and periods only
- Between 3 and 35 characters long
- Cannot begin or end with a period
- No domain-style formats or misleading constructions
- Must be unique across Meta platforms (Instagram, Facebook, and WhatsApp)
That last requirement shapes how the reservation process works. If you already use a handle on Instagram or Facebook, WhatsApp will guide you through a verification step via Meta’s Accounts Center to confirm ownership, and you can then claim that same name on WhatsApp. Creators, small businesses, and organisations get a dedicated claims pathway specifically to maintain a consistent handle across Meta’s platforms.
Users who do not have an existing Meta username face a longer wait. The current reservation system appears to be limited to handles already registered on Instagram or Facebook, which means anyone wanting a brand-new name may need to wait until the full global launch to create one.
WhatsApp has required phone numbers for sign-up and contact since its launch in 2009, while competitors like Telegram have supported usernames for years. The shift to optional phone-number-free communication reflects a broader expectation from messaging app users, who increasingly want convenience without giving out personal contact details to everyone they chat with.
The username feature has been visible in WhatsApp beta builds since October 2025, and the company set a June 2026 deadline for businesses to update their systems to support both usernames and a new Business-Scoped User ID, which allows businesses to message a user even when their phone number is unknown.
Given the scale of WhatsApp’s user base, the window to claim a common name is realistically narrow. Users who receive the in-app notification and want a particular handle should act on it promptly, rather than waiting for the feature to reach full availability.
