Last updated: September 2026
Status as of September 2026: usernames are live. Reservations opened in the app on June 30, 2026. Wave 1 went live July 7 (Algeria, Azerbaijan, Ghana, Libya and Nepal), wave 2 followed from July 20, and the global wave covering the rest of the world is rolling out through September 2026. If you do not see usernames yet, your account is simply in the final wave.
TL;DR
- WhatsApp usernames are here
The feature began its phased beta rollout in April 2026, reached the United States in late June 2026, and is rolling out more widely now. - A username is a public handle you share instead of your phone number
A phone number is still required to use WhatsApp. It just no longer has to be visible. - The rules are specific
3 to 35 characters, lowercase letters, numbers, periods and underscores only, at least one letter, and no "www" or domain endings like .com or .net. - For businesses, the real work is the Business-Scoped User ID (BSUID)
It identifies a customer to your business even when you never see their phone number, and it becomes a required field around June 2026. - Update your automations, CRM, and AI assistants to read and store BSUIDs now
Do it before customers with usernames start arriving without a phone number.
For years your phone number was your identity on WhatsApp. That is the piece that is changing. Below is what usernames actually are, where the rollout stands today, and the specific changes your team needs to make so your messaging, your CRM, and your AI assistants keep working without a hitch.
What is a WhatsApp username?
A WhatsApp username is a unique public handle that identifies you on WhatsApp instead of your phone number. It works much like an Instagram handle. Someone can find you and start a chat using the username, and your phone number stays private.
The feature is optional. People who never set a username keep using WhatsApp exactly as before, and their phone number visibility does not change.
The format rules WhatsApp set are worth knowing before you reserve one:
- Length
3 to 35 characters. - Allowed characters
Lowercase letters, numbers, periods, and underscores. - Must include at least one letter
A username cannot be only numbers. - No web-address patterns
It cannot contain "www" or end in a domain like .com or .net. - No impersonation
Handles that copy an existing person, business, or brand are blocked, and usernames for notable accounts go through verification.
The split that matters for our readers is personal versus business. For a personal user, the username hides the phone number and shows the handle instead. For a business, your phone number still shows in chats, and you gain a unique, searchable username that makes you easier to find and strengthens your brand.
Display name vs username
People mix these two up constantly, so it is worth separating them.
- Display name
The name you type in your profile. It is not unique. Plenty of people can be "John Doe," and it mainly shows to anyone who has not already saved your number. Changing it is cosmetic. - Username
A unique handle that belongs only to you. It lets someone find and message you without ever seeing your phone number.
Put simply, a display name labels you. A username identifies you, and it is the piece that keeps your number private.
Where the WhatsApp username rollout stands right now
This is the part that changed most recently, so let us be precise.
Update for September 2026: Meta is now telling businesses directly. WhatsApp Manager shows an alert titled "Usernames are rolling out: reserve your username and get BSUID-ready" with three steps: claim your preferred username today, it activates when usernames go live in your region, then adopt the business-scoped user ID so you keep reaching customers who use a username instead of a phone number. Two details in that alert matter. Activation is regional, so a reserved username stays in a reserved state until usernames go live where your customers are. And BSUID support is no longer a future requirement: Meta's API has accepted messages addressed to a BSUID since July 2026.
Late June 2026: WhatsApp usernames officially arrived in the United States, enabled over the course of a week. With the latest version of WhatsApp installed, the username option appears under the Account menu in your settings.
WhatsApp started the phased beta rollout of usernames in April 2026, beginning with a limited set of users on Android and iOS. It is being enabled gradually rather than switched on for everyone at once. The broader, global rollout is now underway, and the feature is reported to be extending to web and desktop as it widens. You can read the early rollout reporting on 9to5Google.
On the business side, the plumbing is already live. According to Meta's developer documentation, Business-Scoped User IDs started appearing in message webhooks in early April 2026, and a Meta-hosted contact book that preserves messaging continuity rolled out in the same window. In other words, the identifiers your systems need to handle are flowing today, even before most of your customers have set a username.
Here is the practical timeline:
- Early 2026
Groundwork for BSUID. The identifier begins appearing in webhooks in early April. - April 2026
Username beta rollout starts on Android and iOS for a limited set of users. - Late June 2026
Rollout reaches the United States. Wider global availability continues, and businesses can reserve a username from June 29. - July 2026
Meta's API supports sending messages addressed to a BSUID, not only to a phone number. - September 2026
WhatsApp Manager alerts every business to reserve a username and get BSUID-ready. Activation follows, region by region. - Rest of 2026
Continued global adoption by users and businesses.
The takeaway is simple. This is no longer a "someday" feature to watch. It is shipping, the business side is live, and Meta is now asking every business to act.
Why WhatsApp is adding usernames
WhatsApp's stated focus is privacy and user control, part of Meta's broader privacy progress push. Control over personal information is among the top concerns people have when using WhatsApp. Because every account is tied to a phone number, many people would rather decide whether to reveal that number, since handing it to strangers, groups, or businesses can invite unwanted contact.
That discomfort had a cost. It pushed some users toward apps like Telegram and Signal, where a handle or a private identity has long been the norm. Usernames close that gap.
Usernames answer those concerns by:
- Keeping your phone number private while you stay reachable.
- Letting people connect without exposing sensitive contact details.
- Delivering a long-requested feature that balances privacy with everyday convenience.
There is also an optional username key, a short code that adds a layer of protection. New contacts need the key to message a user, unless the two parties have already saved each other. Businesses messaging through the WhatsApp Business Platform do not need to manage username keys, because the BSUID or phone number already confirms the connection.
What usernames mean for your business: meet the BSUID
If you only remember one acronym from this post, make it BSUID.
A Business-Scoped User ID (BSUID) is a backend identifier that uniquely identifies a WhatsApp user to your specific business. It lets you message a customer even when you do not know their phone number. Per Meta's documentation, the BSUID is assigned to the user_id field and appears in all message webhooks, whether or not the person has turned on the username feature. The format is an ISO country code, a period, and up to 128 alphanumeric characters, for example US.13491208655302741918.
The reason this matters: when a customer with a username messages you, you may never see a phone number. The BSUID is what keeps that conversation stitched to the right customer record.
When you will still see a phone number
The BSUID is always in the webhook. The phone number is not. Once your customers start adopting usernames, a phone number (wa_id) only appears under specific conditions:
- The customer has not set a username
Their number comes through exactly as before. - The customer is already in your business contact book
If the number was shared at the portfolio level, it keeps arriving. - There has been an interaction in the last 30 days
WhatsApp sends the phone number for a rolling 30-day window after each message or call. If a username adopter goes quiet for more than 30 days, their next message can arrive with only a BSUID.

The practical rule: never assume wa_id is present. Parse for a missing phone number, and key your customer records on the BSUID, so a returning customer is recognized whether or not their number travels with the message.
One more tool arrived with the contact book: a read-only check. Meta's Contact Book API lets your system ask whether a phone number is present in your contact book for a specific customer. It answers yes or no and never returns the number itself, which is exactly enough to decide whether a follow-up can go out by phone or has to go by BSUID.
Update your WhatsApp Business API, CRM, and automations
This is the work to schedule now.
- Update your WhatsApp Business Platform integrations
Read and store the BSUID from webhooks and messaging fields. - Teach your CRM and campaign tools to handle BSUIDs alongside phone numbers
Conversations then map to the right contact either way. - Adapt your bots and workflows
Cover the cases where a customer never shares a phone number at all.
It helps to know exactly what each webhook carries, because that drives your parsing logic:
user_id, the BSUID, is always present
It arrives on both incoming messages and status webhooks (sent, delivered, read, failed).wa_id, the phone number, is conditional
It only arrives under the cases above.username
Appears on the delivered and read status webhooks once a customer has set one.parent_user_idandparent_recipient_id
Show up when parent BSUIDs are enabled, for businesses running multiple portfolios under one parent.
Providers are already moving on this. Twilio, Infobip, and others have published guidance on the new BSUID field. Meta's documentation states that supporting BSUIDs is required for all partners and directly integrated businesses on the WhatsApp Business Platform, and the API has accepted messages addressed to a BSUID since July 2026. If you build on a partner platform, check their changelog and confirm your setup is ready.
When you do still need a phone number, for verification or follow-ups, WhatsApp is adding a native sharing flow to cut down on typos. The customer sees a "Send contact info" request with a button and can choose whether to share their number, their username, or both. On your side, typing "/" and selecting "Request contact info" triggers the request, and you can then save the details to a new or existing contact. Update your bots to handle this flow cleanly.
If you want a single view of the work, here is the migration in one place.

Your username becomes part of your brand
Beyond the technical work, a business username is a branding asset.
- It is separate from your display name, which makes you searchable and easy to reach.
- Verified businesses keep their checkmarks, so customers can trust they are talking to the real you.
- You can reserve a username based on your existing WhatsApp display name, Official Business Account, Meta Verified name, or Facebook and Instagram business handles, which gives you an early claim on your brand name. Businesses on the WhatsApp Business API have been able to reserve since June 29, 2026, and WhatsApp Manager now prompts you to do it. A reserved username shows a status of reserved until usernames go live in your region, then approved, which is when customers can see it.
Pick a handle that is simple and close to your brand name, the same way you would choose an Instagram handle. Avoid clever symbols that make you hard to find.

The privacy upside, for customers and for you
Privacy is not just a feature here. It changes the dynamic of every conversation.
- Customers keep their phone numbers private and stay fully reachable.
- Your business keeps its visible number and gains a memorable, searchable handle.
- Control over contact sharing builds trust and cuts down on spam and unwanted exposure on both sides.
- With usernames and BSUIDs in place, your AI assistants and human agents can recognize a returning customer without ever handling a sensitive phone number.
That last point is where this gets interesting for support and sales teams, which is exactly where we live.
How usernames create a better customer experience
A consistent identifier is the quiet ingredient behind good conversational support. When every message ties back to the same customer, the experience stops feeling like a cold start.
- Continuity across channels
Map a username to a customer profile and your team picks up the thread with full history, not a blank screen. - Personalization without exposure
A username and its BSUID give you a stable identifier to segment, target, and personalize against, without ever leaning on a phone number or surfacing sensitive details. - More open conversations
Customers who feel their number is protected tend to engage more freely and more often. - Smarter routing
An omnichannel platform can route a conversation to the right team or the right AI assistant based on who the customer is, not just what they typed.

What we're building at Invent
At Invent, we build AI assistants that chat, talk, and answer from your own data, across WhatsApp and the rest of your channels. Usernames and BSUIDs fit naturally into how the platform already works.
Our Unified Inbox treats a customer as one person across every channel, so a WhatsApp username maps to the same profile your team sees everywhere else. Persistent customer memory means a returning customer is recognized and their history is right there, with no phone number required. And when a conversation needs a person, intelligent handoff passes it to your team with the full context attached.
We are making sure conversations stay connected through this transition, so when a customer reaches you under a username, your assistant still knows who they are and what they need. The plumbing changes. The experience your customers feel should only get better.
Our own username, useinvent, is reserved and waiting for activation in our region, so we are walking the same path as you. If your chatbots and workflows already run on Invent, there is nothing for you to do. We handle the BSUID updates on our side, so your conversations keep working the moment usernames reach your customers.
Get ahead of the change
WhatsApp usernames are a real move toward privacy-first messaging, and they give businesses a short, clear window to prepare. Adopt BSUIDs, update your API integrations and CRM, and get your bots and assistants ready for customers who never share a number. Prepare now and you are ready on day one. Wait, and you are doing the same work under deadline pressure.
Privacy is becoming the default. Make sure your customers can still find you, and that you still know them when they do.
FAQs
How do I find or set my username on WhatsApp?
Once the feature reaches your account, you set and find your username in Settings > Profile, the same place you change your display name. The rollout is phased, so it may not be available to you yet even if others already have it.
What are the rules for a WhatsApp username?
A username must be 3 to 35 characters, use only lowercase letters, numbers, periods, and underscores, and include at least one letter. It cannot contain "www" or end in a domain like .com or .net, and it cannot impersonate another person or brand.
Is a WhatsApp member tag the same as a username?
No. A member tag is a short label, your role, title, or how you are known, that shows under your name inside one specific group, and only that group's members see it. A username is a unique, account-wide handle that lets people find and message you while keeping your phone number private. A tag describes you in a single group. A username identifies you across all of WhatsApp.
What is a BSUID and why does my business need one?
A Business-Scoped User ID is a backend identifier that uniquely ties a WhatsApp user to your business, so you can keep messaging them even when you never see their phone number. It appears in your message webhooks and becomes a required field for business messaging around June 2026.
Do businesses still need customer phone numbers?
Often, yes, for verification or follow-ups. WhatsApp now offers a native "Send contact info" flow so customers can choose to share their number, their username, or both, which reduces typos and errors. Update your bots to handle this flow.
Will phone numbers disappear from WhatsApp?
No. A phone number is still required to use WhatsApp, and existing conversations keep working as before. Usernames are optional and sit alongside or in front of the number for the people who adopt them.
How does WhatsApp prevent username impersonation?
WhatsApp blocks handles that copy an existing person, business, or brand, and usernames for notable accounts require verification. If you spot someone impersonating you, open the chat, tap the profile name at the top, scroll to the bottom, and tap Report.
What should businesses do right now to prepare?
Update your WhatsApp Business Platform integrations to read and store BSUIDs, teach your CRM and campaign tools to handle BSUIDs alongside phone numbers, and adapt your bots and AI assistants for customers who never share a number. If you use a provider, confirm their BSUID support before the June 2026 deadline.
If your username lives on the WhatsApp Business Platform, make sure the account also has a payment method on file: from October 1, 2026 Meta bills replies per message. See how WhatsApp Business API pricing works.
