WhatsApp has started rolling out usernames — a feature users have asked for since Telegram normalised it years ago. Beginning in April 2026 as a limited beta, with global rollout expected in June, WhatsApp users can now create a unique @handle and use it to connect with new people without revealing their phone number. For India’s 500 million+ WhatsApp users, this is one of the most meaningful privacy improvements the app has ever shipped. But the details matter: the phone number is not going away, and understanding what the username system does and does not protect is essential before setting expectations.
Direct Answer: What is the WhatsApp username feature and how does it work? WhatsApp is rolling out usernames — unique @handles that let users connect without sharing phone numbers. Starting April 2026 in limited beta, with global rollout in June 2026. You create a username in WhatsApp → Settings → Profile (only appears once the feature reaches your account). Your username must be 3–35 characters using only lowercase letters, numbers, periods, and underscores. Others can search your @username and message you without seeing your number. Your phone number remains required to register WhatsApp — it is the backend identifier, but no longer needs to be shared with new contacts. An optional 4-digit “username key” adds a second layer: contacts need both your @handle and the key to reach your main inbox.
How WhatsApp Usernames Work
Creating a Username
Once the feature reaches your account (check Settings → Profile for the username field):
- Choose a unique handle — minimum 3 characters, maximum 35
- Only lowercase letters, numbers, periods (
.), and underscores (_) are allowed - Cannot start with
www.or end with.com,.net, or other domain suffixes - Cannot match a username already taken on Facebook or Instagram — Meta ties the system across its platforms
- First come, first served — popular names will go quickly once global rollout begins in June
Changing your username: Meta allows username changes, but there is a 14-day cooldown period between changes. This prevents users from rapidly cycling identities, which could be used for harassment or manipulation.
Finding and Messaging Someone by Username
Once usernames are live, starting a new conversation works two ways:
- Phone number (existing method): Still works exactly as before
- Username search: Search
@usernamein the WhatsApp search bar. If found, you can start a chat without either party sharing a number
The person you message will see your username (not your number) unless they already have your number saved in their contacts. For users who have your number saved already, nothing changes — they continue to see you as before.
The 4-Digit Username Key
This optional feature is the most interesting privacy mechanism in the rollout:
- You set a 4-digit key alongside your username
- To message you, a new contact needs to know both
@yournameAND your 4-digit key - Messages from contacts who only have your username but not the key go to a “Requests” folder
- You can review and accept or decline requests
This is functionally similar to how Instagram filters unknown message requests, but with an extra numeric gate. For public figures, professionals, or anyone who shares their username publicly (in a bio, on a business card, in a forum) but wants control over who can reach them directly, the key provides meaningful friction against spam and unwanted contact.
What the Username Feature Does NOT Change
Understanding the limits is as important as the feature itself.
Your phone number is still stored by Meta. Usernames hide your number from new contacts. They do not change what data Meta holds. WhatsApp still knows your number, your device, your IP address, and your usage metadata. The username is a contact-sharing privacy feature — not a data minimisation feature.
Existing contacts still see your number. Anyone already in your contact list (or who has you saved) continues to see your number. Usernames are specifically for new connections made after the feature rolls out.
Meta cross-platform tracking. Your username is shared across Facebook and Instagram. Meta can link your WhatsApp identity to your other Meta platform identities. If you use different names on different platforms for privacy, be aware the username system unifies them unless you intentionally use a pseudonymous handle on all three.
End-to-end encryption is unchanged. WhatsApp’s E2E encryption applies to all messages regardless of whether the connection was established via phone number or username. The privacy improvement from usernames is about contact discovery — not message security.
WhatsApp is still a Meta product. Metadata — who messages whom, when, how often, from which location — is still visible to Meta. Signal’s architecture minimises this metadata collection; WhatsApp’s does not. For threat models that include Meta itself as an adversary, usernames do not change the calculus.
The Business Impact: BSUID
For the 200 million+ businesses using WhatsApp Business and the WhatsApp Business API, the username rollout brings a significant technical change that requires preparation.
The Business-Scoped User ID (BSUID):
WhatsApp is introducing a new identifier for business-to-customer conversations: BSUID (Business-Scoped User ID). When a customer contacts a business via username (without sharing their phone number), the business receives a BSUID rather than a phone number as the customer identifier.
Critically: the same user has a different BSUID for each business they interact with. This is a privacy feature — Business A cannot use a customer’s BSUID to track that customer’s interactions with Business B. Each business relationship is isolated.
What this breaks: CRMs, chatbots, and automation workflows that use phone numbers as primary customer identifiers will encounter customers they cannot match to existing records when those customers use usernames. A customer who previously chatted via phone number and returns via username will appear as a new contact in phone-number-based systems.
Timeline for businesses:
- March 31, 2026 → BSUIDs begin appearing in webhooks
- May 2026 → BSUID testing available for API-integrated businesses
- June 2026 → Username rollout begins in test countries
- Rest of 2026 → Global rollout continues
Any business using the WhatsApp API with a CRM that stores phone numbers as primary keys should begin planning for BSUID compatibility now.
WhatsApp Username vs Signal vs Telegram
How does this change stack up against the privacy features of WhatsApp’s competitors?
| WhatsApp usernames | Signal | Telegram | |
|---|---|---|---|
| Username/handle | ✅ @handle (June 2026) | ✅ @username (existing) | ✅ @username (existing) |
| Phone number required | ✅ For registration | ✅ For registration | ✅ For registration |
| Phone hidden from contacts | ✅ New contacts | ✅ Yes (by default) | ✅ Optional |
| Metadata collected | ⚠️ Significant (Meta) | ✅ Minimal | ⚠️ Significant (Telegram) |
| E2EE by default | ✅ Yes (all chats) | ✅ Yes (all chats) | ❌ Only Secret Chats |
| Open source client | ❌ No | ✅ Yes | ✅ Client only |
| Cross-platform identity | ⚠️ Meta (FB, IG, WA) | ❌ None | ❌ None |
Signal’s username system (launched 2024) works similarly — you create a username, your number is hidden, and Signal added a link system (signal.me/u/username). Signal’s advantage: it is also the only major messenger with minimal metadata collection. Signal cannot see who you message or when.
Telegram has had usernames since launch and handles them more permissively — you can change them freely, find users by @username in a global search, and create public channels under usernames. Telegram does not have E2EE for regular chats (only Secret Chats), which is a significant security trade-off.
The honest verdict: WhatsApp’s username feature brings it closer to Telegram’s and Signal’s contact discovery model. For the average user who is already on WhatsApp and simply wants to stop sharing their phone number with new contacts, this is a meaningful improvement. For users with serious privacy requirements — activists, journalists, people in sensitive situations — Signal remains the stronger choice because it minimises what the provider itself knows about your communications.
How to Set Up Your WhatsApp Username (When Available)
The feature is rolling out in phases — not everyone has it yet. Check:
WhatsApp → Settings → Profile
If you see a “Username” field, the feature is available on your account. If not, it has not reached you yet. The feature spreads gradually via app updates; you cannot force-enable it.
When you do have access:
- Tap the Username field
- Enter your desired handle
- WhatsApp will confirm availability instantly (first come, first served)
- Optionally enable the 4-digit username key in Privacy settings
- Share your @handle instead of your number for new connections
Username rules to remember:
- 3–35 characters
- Lowercase letters, numbers,
.and_only - Cannot match your Facebook or Instagram username if those are already taken
- No web address formats (no
www.prefix or.com/.netsuffix) - 14-day cooldown between changes
The Sovereignty Assessment
WhatsApp usernames are a genuine privacy improvement for contact discovery — specifically, the everyday friction of sharing your phone number with new people, joining online communities, or handling business contacts. For India’s massive WhatsApp user base, where the app is used for everything from family groups to business negotiations to community organising, number privacy has real stakes.
The improvement is real but bounded. WhatsApp’s metadata collection, its status as a Meta product, and the continued phone number requirement for registration mean this is not a privacy transformation — it is a privacy upgrade. The phone number remains WhatsApp’s backbone; usernames are a layer on top of it.
For users with higher privacy requirements, the honest recommendation remains: Signal for private conversations, WhatsApp for the conversations that have to happen on WhatsApp because everyone else is there.
FAQ
When will WhatsApp usernames be available to everyone? Global rollout is expected in June 2026. The April 2026 rollout is a limited beta for select users. Check WhatsApp → Settings → Profile for the username field — if it is there, you have access.
Can I find anyone on WhatsApp by username if I don’t have their number? Yes, once usernames are live — search the @username in the WhatsApp search bar. If they have the 4-digit username key enabled, you will need both the handle and the key to reach their main inbox.
Does the WhatsApp username feature work on WhatsApp Web and desktop? Yes — the April 2026 update synchronises username settings across all linked devices including WhatsApp Web, and the standalone Windows and macOS clients.
Will my existing contacts see my username or my phone number? Existing contacts who have your number saved will continue to see your number. Your username is specifically for new connections made via username search. You cannot retroactively hide your number from people who already have it.
Is WhatsApp username the same as Signal’s username? Functionally similar — both hide your phone number from new contacts. Signal’s implementation has been live since 2024. The key difference: Signal collects minimal metadata about your conversations; WhatsApp (Meta) collects significantly more. Both still require a phone number for registration.
Should I switch to Signal instead of waiting for WhatsApp usernames? If your privacy concern is specifically about sharing your number with new contacts, WhatsApp usernames solve that problem when they arrive. If your privacy concern is about what the provider itself knows about your communications — who you message, when, from where — Signal addresses that and WhatsApp does not, regardless of the username feature.
