How to Reserve Your WhatsApp Username (and What It Means for Privacy)

How to reserve your username right now

1. Update WhatsApp to the latest version (App Store or Play Store).
2. On your phone, open Settings > Account > Username.
3. Type the name you want and check it is available.
4. Save it. That reserves the name for you to switch on later, when the feature goes live in your country.

Two things that trip people up. First, this is mobile only for now, you cannot reserve from WhatsApp Web or Desktop. Second, reserving the name does not turn the feature on yet. WhatsApp is rolling usernames out gradually over the coming months and will ping you in-app when yours is active. So reserve today, use later.

The username rules (so you do not waste tries)

• 3 to 35 characters.
• It has to include at least one letter, and the first character must be a letter.
• Letters, numbers, periods, and underscores are the usual allowed set.
• It can't start with "www." and can't end with a domain extension like ".com".

My advice on what to pick: treat it like a handle you would print on a business card, not a throwaway. There is no public directory and no "people you may know" for usernames, so nobody discovers you by browsing. They have to type your exact name. That means a clean, memorable username you can paste into a bio or an email signature beats something clever that people will misspell. If you run a business or have a brand, reserve that name now before a squatter does.

What it actually hides (the honest version)

The pitch is "chat without sharing your phone number," and that part is true: once usernames are live, you can message new people, businesses, and group chats by username, without handing over your number. For anyone who has been burned by a number leaking into a spam list, that is a real upgrade.

Here is the part the headlines skip. You still need a phone number to create and log into WhatsApp, so Meta still has it. And anyone who already has your number, every existing contact, still has it. A username hides your number from newpeople going forward. It is not a fresh anonymous identity, and it is not retroactive. Think of it as closing the door to strangers, not erasing your past.

There is one genuinely smart privacy piece: an optional username key. Turn it on and people need that key before they can message you by username for the first time, which kills the obvious spam problem of a guessable handle. If you pick a common username, switch the key on.

My take: overdue, useful, oversold

Signal and Telegram have had usernames for years, so this is Meta catching up rather than breaking new ground. That said, for three billion people who currently have no choice but to expose a phone number to talk to a stranger, it is the most meaningful privacy change WhatsApp has shipped in a while. Just calibrate your expectations: less number exposure to new contacts, not anonymity from Meta.

While you are in there, lock the account down

A username is worth nothing if someone hijacks the account behind it. Two minutes of housekeeping while you are in Settings: turn on two-step verification and set a PIN you do not reuse anywhere else. If you want a genuinely strong one, our free password generator and strength checker runs in your browser (nothing is sent anywhere). And if you are into the wider messaging privacy shift, the encrypted RCS change in iOS 26.5 is part of the same trend.
