WhatsApp Username: Everything You Need to Know About the New Feature
.jpg.jpeg "Anantya.ai")
For years, WhatsApp has asked you to share your phone number before you can even say hello to someone new. That is finally changing. WhatsApp is rolling out Usernames — a way for people to connect and chat without handing over their mobile number. The feature has been talked about since 2023, but it only started reaching real users in April 2026, with a wider public rollout beginning in July 2026.
For everyday users, this is a privacy win. You can pick a handle like @yourname and use it instead of your number when you meet someone new on WhatsApp. Your number stays private, and only people who know your exact username can find you (there is no public directory or search suggestions, so this isn't like browsing profiles on social media).
For businesses, the update matters even more. WhatsApp is the backbone of customer communication for millions of companies, and anything that changes how customers are identified on the platform affects sales, support, and marketing. Alongside usernames, Meta has introduced a new backend identifier called the Business-Scoped User ID (BSUID), which businesses using the WhatsApp Business API need to understand and support.
This guide breaks down what WhatsApp usernames are, how they work, what's confirmed versus what's still uncertain, and what it all means for businesses running customer conversations, marketing campaigns, and Click to WhatsApp ads on the platform.
What is WhatsApp Username?
A WhatsApp Username is an optional handle — something like @yourname — that you can create and share with people instead of your phone number. Once someone has your username, they can search for you inside WhatsApp and start a chat, while your actual number stays hidden.
Meta introduced usernames to close a long-standing gap in WhatsApp's privacy story. Telegram has had usernames since 2013, and Signal added them in 2022. WhatsApp, with nearly three billion users, only got the feature in 2026.
Here's the current rollout picture:
WhatsApp began a phased rollout to a limited group of users on April 8, 2026.
In late June 2026, WhatsApp officially confirmed usernames were coming and opened up early reservations, so people could lock in the handle they wanted before the full launch.
The first country wave went live on July 7, 2026, and by mid-July, WhatsApp had started rolling the feature out to select stable and beta users, with eligible users seeing a banner on their home screen confirming access.
The rollout is expanding gradually over the coming weeks, so not everyone has access yet.
Usernames are entirely optional. You can keep using WhatsApp exactly as before without ever creating one, and your phone number remains linked to your account for login, verification, and recovery — it just isn't the only thing you have to give out to start a conversation anymore.
Why Did WhatsApp Introduce Usernames?
A few reasons stand out:
Privacy. Sharing your phone number to join a group chat, talk to a stranger, or message a business has always felt like handing over more than you wanted to. A username lets you keep that number for yourself.
Less spam and unwanted contact. WhatsApp has said the feature is meant to give its three billion users more control over who can reach them, and the company built it with no public directory of usernames and no autocomplete suggestions — so someone needs to know your exact handle to message you for the first time.
Catching up with other messaging apps. Telegram and Signal users have long been able to chat without exchanging numbers. WhatsApp usernames bring it in line with that expectation, especially for people who message strangers, communities, or businesses regularly.
User safety. Phone numbers can be used to track, spam, or impersonate people. A username-first identity reduces how much personal data is exposed by default.
How WhatsApp Username Works
Setting up and using a WhatsApp username is fairly simple, based on what's rolled out so far:
Check availability. Go to Settings > Profile (or the Username section, where available) to see if the feature has reached your account.
Reserve or create a username. If the feature is live for you, you can create, edit, or delete your username at any time from the Profile page. WhatsApp also allowed early username reservations, and if you had linked your Meta Accounts Center, you could reserve the same username you already use on Facebook or Instagram, though that's optional.
Uniqueness. Your username needs to be unique — and not just on WhatsApp. Because Meta links accounts across its apps, your handle generally needs to be unclaimed across Meta's platforms too.
Searching. Someone who knows your username can look you up inside WhatsApp and start a chat. There's no browsing or public listing — you need the exact handle.
Sharing. You can hand out your username on a business card, website, social bio, or ad instead of your phone number.
Messaging. Once a conversation starts, it works like any other WhatsApp chat. The difference is simply what identity was used to begin it.
WhatsApp Username Rules
WhatsApp has set clear formatting rules for usernames. Some specifics have varied slightly across early beta reports, but the core rules that have been consistently confirmed are:
Because handles are first-come, first-served, it's worth reserving your preferred username as soon as the feature becomes available to you — especially for a business name or brand handle.
Benefits of WhatsApp Username
Better privacy — your phone number is no longer the default thing you hand out to strangers.
Easier sharing — a memorable handle is simpler to put on marketing material, packaging, or a social bio than a phone number.
Brand identity — a consistent @handle across Meta platforms builds recognition.
Faster communication — customers can find and message you without digging up or saving a number first.
No need to expose phone numbers — reduces the risk of spam, scraping, or impersonation tied to your number.
WhatsApp Username for Businesses
This is where the update becomes genuinely strategic, not just a privacy feature.
Customer trust. Customers are often hesitant to message a business chat number they don't recognize. A branded, verifiable username feels more familiar and trustworthy — closer to messaging a known handle than an unknown 10-digit number.
Easier conversations. Prospective customers can find and message a business by typing a memorable handle instead of searching for or saving a phone number.
Brand recognition. A consistent username across WhatsApp, Instagram, and Facebook strengthens brand recall and makes cross-platform marketing simpler.
Customer support. Support teams can point customers to one clean, memorable handle in help articles, emails, and social posts, rather than juggling different phone numbers per region or team.
Lead generation. A short, brandable username is easier to include in ads, landing pages, and QR codes — reducing friction between someone seeing an ad and actually starting a chat.
This is exactly the kind of shift where working with a WhatsApp Business API partner like Anantya.ai helps — businesses need their systems, CRMs, and chat flows ready to handle both phone-number-based and username-based customers as the rollout expands.
WhatsApp Business API and Usernames
This is an important, and still-evolving, part of the update. Here's what's confirmed and what's not:
Confirmed: Alongside usernames, Meta has rolled out a new backend identifier for the WhatsApp Business API called the Business-Scoped User ID (BSUID). A BSUID is a unique identifier businesses can use to message a WhatsApp user even when they don't know that user's phone number, and it's assigned to the user_id parameter in message webhooks — regardless of whether the customer has adopted a username. The BSUID format includes an ISO country code followed by a period and up to 128 alphanumeric characters (for example, US.13491208655302741918), it's scoped to a specific business portfolio, stays stable even if a user changes their username, and gets regenerated only if the user changes their phone number.
Supporting BSUID is required for all partners and directly integrated businesses on the WhatsApp Business Platform, as well as Click to WhatsApp Ads (CTWA) advertisers — because businesses can't control whether their customers choose to adopt a username, they need BSUID support so they don't lose the ability to message those customers.
Also confirmed: If a business needs a customer's phone number and it isn't available because the customer adopted a username, WhatsApp allows the business to request it directly inside the chat — either through a free-form interactive message during an active session, or through a template button that can be used outside the session window. In both cases, the customer sees a prompt and chooses whether to share their contact details. Authentication templates — one-tap, zero-tap, and copy-code — are not affected and still require a phone number.
Also confirmed: Business usernames only change the business's displayed name on WhatsApp; they are not used during WhatsApp Business Account onboarding or phone number registration, which still requires a phone number.
Still developing / not officially confirmed: How far verified-business badges, discovery, or directory-style search will extend for business usernames, and how deeply usernames will eventually integrate with catalogs, payments, or other commerce tools, are not yet fully detailed by Meta. Businesses should treat these as likely future directions rather than confirmed features, and keep an eye on official WhatsApp Business Platform documentation as the rollout matures.
How WhatsApp Username Can Improve WhatsApp Marketing
Usernames add a new, more approachable layer to WhatsApp Marketing:
Better campaign experience — a clean @handle in an ad or landing page feels more inviting to tap than an unfamiliar phone number.
Higher trust — a recognizable, consistent brand handle reduces the "is this spam?" hesitation many users feel before starting a business chat.
Easier customer engagement — customers can initiate contact using a handle they've already seen on Instagram or a business's website.
Reduced friction — one less step (finding, copying, or saving a number) between interest and action.
Personalized messaging — combined with BSUID-based customer records, businesses can maintain continuity of conversation history and personalization even for customers who never share a phone number.
What Will Change for Click to WhatsApp Ads?
Click to WhatsApp (CTWA) ads are one of the areas most directly touched by this update, since CTWA advertisers are required to support BSUID to keep receiving and processing messages from ad clicks.
Likely (but not yet fully confirmed) impacts include:
Easier customer conversations — clicking an ad and landing in a chat with a brand handle may feel more trustworthy than an unfamiliar number.
Less hesitation due to phone number privacy — some users avoid messaging businesses because it exposes their number; usernames may lower that barrier for privacy-conscious customers.
Better lead generation — a smoother, lower-friction path from ad click to conversation could help more clicks convert into actual chats.
Potential increase in CTR and conversation rates — as trust and familiarity improve, click-through and conversation-start rates could rise, though real-world data on this is still limited since the rollout is recent.
Businesses running CTWA campaigns should prioritize BSUID support in their tech stack now, since it's a requirement rather than optional, and treat the marketing upside as a promising possibility to monitor rather than a guaranteed outcome.
WhatsApp Username vs Phone Number
Use Cases
Small businesses — share one memorable handle instead of juggling personal and business numbers.
Enterprises — maintain consistent brand handles across regions and support teams.
Influencers — connect with followers using the same handle as their other social profiles.
Customer support — point customers to a single, easy-to-remember support handle.
Education — institutions can share one recognizable handle for admissions or student queries.
Healthcare — clinics can offer a private, trustworthy way for patients to reach out without publishing a personal or front-desk number widely.
Real estate — agents can put a branded handle on listings and signage instead of a personal number.
E-commerce — stores can use a consistent handle across ads, packaging, and social bios for order support.
Challenges
Username availability — with billions of users and cross-Meta uniqueness rules, popular or short handles will get claimed quickly.
Fake usernames — bad actors could register handles that look similar to real brands or people.
Brand impersonation — businesses will need to actively claim and protect their handles early, and verify official accounts wherever possible.
Verification — how business verification and usernames interact is still being clarified by Meta.
Adoption timeline — since the rollout is gradual and phased by country and user group, not all customers or businesses will have access at the same time, which means both phone numbers and usernames will need to be supported side by side for a while.
Future of WhatsApp Usernames
Looking ahead, usernames are likely to intersect with several other areas of WhatsApp's roadmap, though specifics remain unconfirmed by Meta:
AI — smarter, handle-based customer identification could feed more personalized AI-driven support and marketing.
Business Messaging — deeper integration of usernames into customer profiles and conversation history.
Business API — continued rollout of BSUID-based tooling across CRMs, chatbots, and campaign platforms.
Payments — a username-based identity could eventually simplify payment requests, though this isn't officially detailed yet.
Commerce — catalogs and storefronts could become easier to link to a recognizable handle rather than a number.
Meta ecosystem — tighter alignment between WhatsApp, Instagram, and Facebook handles is already part of the reservation process, and this cross-platform identity is likely to deepen over time.
Conclusion
WhatsApp usernames mark one of the biggest identity changes the platform has made since launch. For individual users, it's a straightforward privacy upgrade — you finally get to choose what you share to start a conversation. For businesses, it's a bigger shift: customer identification is moving beyond the phone number, and systems built around WhatsApp Business API need to be ready to handle both phone numbers and BSUIDs during this transition.
The marketing upside — friendlier ad experiences, more trustworthy brand handles, and potentially better conversion on Click to WhatsApp ads — looks promising, though it's still early days and real-world data will take time to confirm the extent of the impact. What is clear is that businesses that prepare their tech stack, claim their brand handle early, and stay current with Meta's official documentation will be in the best position as the rollout expands globally.
