WhatsApp has started letting users reserve a username, the biggest change to how the app handles identity since it launched in 2009. Starting this week, you can claim a unique handle now and use it later this year, when the full feature goes live. The point is privacy: a username lets you message someone new, or be messaged, while keeping your phone number to yourself. The number still anchors your account for login and recovery, so the username adds a layer rather than replacing anything.The company is opening reservations ahead of the launch for a simple reason. With over three billion people on WhatsApp, a great many handles will overlap, and the early window gives everyone a chance to grab the one that matters to them before someone else does.What WhatsApp usernames actually areA username is an optional handle, something like a social-media name, that you can share instead of your phone number when you connect with someone new. Once you have one, a person who knows your exact username can find you inside WhatsApp and start a chat, while your digits stay hidden from them. Your phone number remains tied to the account behind the scenes, for sign-in, verification and recovery, so it keeps working as it always has. The username simply becomes the thing you hand out.Alice Newton-Rex, vice-president and head of product at WhatsApp, framed the logic plainly in a briefing. Meeting someone new, she said, whether a classmate, a neighbour or someone from an event, can make sharing a phone number feel like a big step, since the number ties into so much of a person's life. Usernames, she added, are designed to give people control over who sees that number in the first place. The feature is entirely optional; anyone who prefers the old way can carry on exactly as before.How Will Usernames Work?The mechanics are deliberately narrow, and that is the privacy feature. The design omits any public directory or search, so a username surfaces for someone only when they already know it exactly. You share your handle the way you would a name, by speaking it or sending it in a message, and the other person types it into WhatsApp to reach you. From that first contact, your phone number stays invisible to them, and theirs to you, until you each choose to save the other's number.For an extra gate, WhatsApp lets you set a username key, a secret that someone must also know before they can send you that first message. Think of it as a second lock on the door: the handle gets them to your profile, the key lets them knock.A few format rules govern the handles themselves. A username runs from 3 to 35 characters, uses only lowercase letters, numbers, full stops and underscores, and has to begin with a letter, so a string of numbers alone will fail. Two full stops in a row are out, and a handle must avoid starting with "." or ending in a domain such as ". com". One feature is still on the way: username-based calling, which would let people place voice and video calls while the number stays hidden, sits in development for a later update.How To Reserve A Username?Reserving a handle takes well under a minute once the option reaches your account. The rollout is gradual, so WhatsApp will send an in-app notification when the reservation screen is ready for you, and the steps are these:Update WhatsApp to the latest version on Android or iOS.Open Settings, tap Account, then tap Username.Type the handle you want. The app checks availability instantly and offers a generator if you need ideas.Confirm to reserve it, and it is held for you until the full feature launches.There is a second path for anyone who wants to carry over an existing identity. Creators, small businesses and organisations can claim the same username they already use on Instagram or Facebook, keeping a consistent presence across Meta's apps. To do that, link your WhatsApp account to Meta's Accounts Center, the hub that already connects Instagram and Facebook, and verify that you own the handle. For a brand-new username unique to WhatsApp, you can skip Accounts Center entirely and reserve straight away. If the Username option is missing from your settings, the rollout has yet to reach you, so keep the app updated and check back.What About Safety?Safety sits at the centre of the design rather than bolted on after. Because the system omits any directory, search or suggestions, the only way a stranger reaches you is by knowing your precise handle, which puts first contact firmly in your hands. The optional username key adds a second barrier on top, and you can change or remove your username, or switch the feature off, at any moment.WhatsApp has built in protection against impersonation as well. It has held back high-value handles for well-known figures, public bodies and organisations, so a famous name stays beyond a bad actor's reach, and it verifies notable accounts while blocking handles that try to pose as a person or brand. Your phone number, meanwhile, stays hidden from the people who reach you by username, even as it keeps anchoring your account.One caution is worth keeping in mind. Using the identical handle across WhatsApp, Instagram and Facebook can make it easier for a stranger to connect your profiles into a single picture of you. Anyone who values a clean separation between their personal, professional and public lives should pick a different username for each, and treat the WhatsApp handle as its own identity rather than a copy of the others.Why Early Reservation Matters?The maths makes the case on its own. Three billion accounts chasing a finite pool of short, memorable handles means the good ones disappear fast, and a reservation made now is a name held for you when the feature opens to everyone later in the year. Wait, and your first choice may belong to someone else.The cross-app angle sharpens the urgency for anyone carrying a known name. A handle you use on Instagram might also exist on Facebook under a different owner, and the two are effectively racing for the same single spot on WhatsApp, so the person who reserves first wins it. For creators and businesses whose brand recognition lives in their handle, that makes acting early a matter of protecting an asset rather than mere convenience. The dedicated claims pathway through Accounts Center exists precisely so they can lock in a consistent identity before the rush.The India readIndia matters here more than any market, since it is WhatsApp's largest with hundreds of millions of users, and the country anchors the feature's promotion, including a campaign fronted by Aamir Khan. The appeal is local and concrete. A username lets a buyer, a seller or a new acquaintance reach you for a deal, a flat or a community group while your number stays private, which speaks directly to everyday concerns around spam, unwanted contact and personal safety. For India's vast base of small sellers and creators who run their livelihoods through WhatsApp, a recognisable, shareable handle that keeps the personal number out of strangers' hands is a practical upgrade rather than a novelty.WhatsApp username FAQDo WhatsApp usernames replace your phone number? Your username works alongside your phone number rather than replacing it. You still need the number to register, log in and recover your account. The username is what you share with new contacts, so they reach you while your number stays hidden.How do you reserve a WhatsApp username?Update to the latest version, then open Settings, tap Account, and tap Username.
