Discover how WhatsApp usernames, launching in June 2026, will transform business messaging, user privacy, and brand discoverability. This guide breaks down everything you need to know – from the introduction of BSUID (Business System User IDs) to key integration steps and the official rollout roadmap.
Key Takeaways
- Businesses that already have customer phone numbers from existing conversations will retain this data and can continue messaging their contacts without disruption.
- Companies can still send messages to known phone numbers, even if users choose to create and use a WhatsApp username.
- For users who do not adopt a username, there will be no change to the visibility of their phone numbers.
- Authentication and verification messages will continue to be sent exclusively to phone numbers, just as they are today.
What are WhatsApp usernames?
Launching in June 2026, WhatsApp usernames introduce a new way for users to connect by allowing them to choose a unique handle that appears in place of their personal phone number in both one-on-one chats and group conversations.
This update is designed to strengthen privacy, giving users greater control over how they share their contact details on WhatsApp.
- For individual users: Usernames replace phone numbers in chats, helping keep personal contact information private.
- For businesses: Phone numbers remain visible, but brands can also claim unique, searchable usernames – boosting discoverability, improving brand presence, and making it easier for customers to find and engage with them.
Why is WhatsApp introducing usernames this 2026?
WhatsApp continues to prioritize privacy and user control. Many users have voiced concerns about sharing their phone numbers, which have traditionally been the default identifiers on the platform. These privacy worries have contributed to some people switching to alternative messaging apps like Telegram or Signal.
With the introduction of WhatsApp usernames, these concerns are addressed by:
- Protecting phone number privacy in all messaging interactions.
- Allowing users to connect and communicate without revealing sensitive contact information.
- Providing a highly requested feature that balances enhanced privacy with seamless communication.
This update reinforces WhatsApp’s commitment to keeping conversations secure while making it easier for users to connect safely.
Key Business Impact And Steps To Take
BSUID WhatsApp integration
To support the upcoming WhatsApp username feature, WhatsApp is introducing a new customer identifier called the Business-Scoped User ID (BSUID). This unique identifier links users to businesses while keeping phone numbers private whenever usernames are in use.
Key updates for businesses and partners include:
- WhatsApp Business API integration: Update webhooks and messaging fields to fully support BSUID.
- CRM and campaign systems: Ensure BSUID is handled alongside phone numbers to map conversations accurately.
- Messaging bots and workflows: Adapt processes to accommodate users who choose not to share their phone numbers.
By adopting BSUID, businesses can maintain seamless communication while respecting user privacy, ensuring compliance with WhatsApp’s new privacy-first approach.
Avoid losing access to certain messaging scenarios
To ensure uninterrupted communication, businesses and partners need to implement the BSUID. Without adopting BSUID, certain messaging scenarios may stop working when interacting with users who have chosen WhatsApp usernames.
Messaging flows that could be disrupted include:
- Messages initiated from ads that click to WhatsApp – campaigns may fail to reach users without BSUID integration.
- Service messages – automated notifications or customer support messages may not be delivered.
Adopting BSUID is essential for maintaining smooth messaging operations, protecting user privacy, and ensuring your WhatsApp business communications continue to function seamlessly.
What is not changing
Even with the launch of WhatsApp usernames, phone numbers remain a core part of how WhatsApp works, while new privacy features give users more control over their information. Businesses that already have customer phone numbers from existing conversations will retain this data and continue messaging their contacts without disruption.
Key points for businesses:
- Business-initiated messaging: Companies can still send messages to known phone numbers, even if the recipient has set up a WhatsApp username.
- Users without usernames: For users who don’t adopt a username, phone number visibility remains unchanged.
- Authentication messages: Verification or authentication messages continue to be sent exclusively to phone numbers, just as they do today.
By combining usernames with traditional phone-based messaging, businesses can maintain reliable communication while respecting user privacy.
WhatsApp usernames for businesses: searchable, verified, and professional
With the upcoming WhatsApp username feature, businesses gain unique handles that are separate from their display names, making it easier for customers to find and connect with them – similar to platforms like Telegram or Signal.
Key benefits for businesses include:
- Unique, searchable usernames: Stand out and ensure customers can reach your brand quickly.
- Verified businesses retain blue checkmarks: Protect your brand identity and reassure users that they are interacting with an authentic business.
- Professional username formatting: Follow clear and concise rules to maintain a polished, trustworthy presence.
These updates enhance brand discoverability on WhatsApp while maintaining professionalism and trust with your audience.
WhatsApp usernames: privacy for users, discoverability for businesses
With the new WhatsApp username system, users can keep their phone numbers private while staying fully connected and reachable. At the same time, businesses benefit from enhanced branding and customer engagement.
Key advantages include:
- Brand-centric usernames for businesses: Phone numbers remain visible, but businesses get memorable usernames that clients can easily search and recognize.
- Enhanced privacy and trust: Users control how their contact information is shared, reducing spam and unwanted exposure.
- Secure, personalized customer journeys: By combining WhatsApp usernames with BSUIDs, AI or human agents can identify clients and deliver personalized interactions without relying on sensitive phone numbers.
This update helps businesses improve discoverability and strengthen customer relationships while keeping user privacy front and centre.
How WhatsApp usernames help create a better customer experience
The introduction of WhatsApp usernames and BSUIDs is set to transform how businesses connect with customers, enabling smarter, more secure, and personalized messaging across devices and channels.

- More precise campaigns and workflows: Businesses can use usernames as consistent, unique identifiers for campaigns, engagement strategies, and automated workflows.

- Searchable and memorable business usernames: Customers can find the right business quickly, reducing friction in support or purchase journeys.
- Intelligent conversation routing: Omnichannel systems can use usernames and BSUIDs to ensure fast, contextual responses from the right team members or AI assistants.
