WhatsApp is rolling out one of its biggest changes ever — usernames. For the first time in the app’s history, you won’t need to share your phone number to chat with someone new. Instead, you can share a simple @username, just like on Instagram or Telegram.
This guide covers what the feature is, how it works, the rules for choosing a username, the rollout timeline, and its implications for your privacy.
What Is the WhatsApp Username Feature?
The username feature lets you create a unique handle — something like @yourname — and use it instead of your phone number when connecting with new people. Anyone who knows your username can search for you within WhatsApp and initiate a chat. Your phone number stays hidden from them.
Your number is still linked to your account behind the scenes for login, verification, and account recovery. It’s simply no longer the piece of information you have to hand out every time you meet someone new.
WhatsApp’s VP of Product, Alice Newton-Rex, explained the thinking behind it: sharing a phone number with a new classmate, neighbour, or someone met at an event can feel like a big step, since a number is personal and tied to many parts of your life. Usernames give people a way to chat without handing over that information.
How the Username Feature Works
- Go to Settings > Account > Username in the app.
- Choose an available handle that meets WhatsApp’s rules.
- Once set, your username is linked to your account, and you can share it instead of your number.
- Existing contacts who already have your saved number will keep seeing it as normal — the change only affects how new contacts reach you.
Importantly, WhatsApp has confirmed there is no public directory of usernames and no autocomplete suggestions. Someone must know your exact username to message you for the first time, which keeps the system from turning into a searchable public list.
Username Rules: What You Can and Can’t Choose
WhatsApp has set clear rules for creating a username:
- Must be 3 to 35 characters long
- Only lowercase letters (a–z), numbers (0–9), periods, and underscores are allowed
- Must include at least one letter (no all-number or all-symbol handles)
- Cannot start with “www.” or end with a domain like .com or .net
- Must be available across Meta platforms — meaning it can’t already be taken on Instagram or Facebook
Businesses, creators, and organisations with existing Instagram or Facebook accounts get the option to claim a matching username for brand consistency.
Extra Privacy Layer: The Username Key
For people worried about others guessing their handle, WhatsApp is adding an optional username key — a short code that acts like a password for your username. If you turn this on, someone needs both your username and your key to message you for the first time. WhatsApp recommends avoiding the same handle you use on other social apps, so it’s harder for strangers to find and message you.
Rollout Timeline
- April 2026 – Limited beta testing began for a small group of users.
- June 29, 2026 – WhatsApp officially announced the feature and opened username reservations for everyone, letting people lock in their preferred handle before the full launch.
- July 7, 2026 – First country wave goes live in Algeria, Azerbaijan, Ghana, Libya, and Nepal.
- July 20, 2026 – Second wave of countries.
- From September 2026 – Gradual rollout to the rest of the world.
WhatsApp has said it will notify users in-app once the feature becomes available in their country, though exact dates per region have not been confirmed.
Is the Username Feature Mandatory?
No. It’s completely optional. You can keep using WhatsApp exactly as before, contacting and being contacted by phone number, and skip usernames entirely. You can also change your username or turn the feature off at any time.
What This Means for Businesses
For businesses using the WhatsApp API, the change introduces a new identifier called a BSUID (Business-Scoped User ID). When a customer messages a business using a username instead of a phone number, their number is replaced by a BSUID in the webhook. If a company’s CRM or chatbot only recognises phone numbers, conversations coming through usernames could be missed. Businesses are advised to update their systems ahead of the rollout so customer messages don’t slip through the cracks.
Why This Matters for Privacy
Phone numbers are tied to a lot of personal information and can be misused for spam, scams, or unwanted contact. By letting people connect through a username instead, WhatsApp is closing a long-standing privacy gap on a platform used by more than three billion people worldwide. Combined with the optional username key and existing tools like blocking and silencing unknown callers, users get more control over exactly who can reach them.
