WhatsApp has traditionally connected people through phone numbers. Now, WhatsApp Usernames offer another way to connect without sharing a personal phone number with every new contact. The change is important for individual users, business owners, sales teams, and marketers who rely on WhatsApp for daily communication.
Meta announced username reservations in June 2026, with the feature rolling out gradually. Users can reserve a unique username and use it to help protect their phone number when connecting with people who do not already have it saved. However, usernames are optional, and a phone number is still required for a WhatsApp account.
For businesses, the update also raises practical questions about brand identity, customer records, WhatsApp Business API integrations, and CRM workflows. Here is what you need to know.
What Are WhatsApp Usernames?
WhatsApp usernames are unique identifiers that allow people to connect using a handle, such as @yourname, instead of sharing their phone number with every new contact.
Unlike a display name, which can be shared by multiple people, a username must be unique. Users can provide their username to someone who wants to start a conversation without exchanging phone numbers first.
For example, a freelancer could share a WhatsApp username with a prospective client instead of immediately providing a personal number.
Key points about WhatsApp usernames include:
- They are optional rather than mandatory.
- Each username must be unique.
- Users can change or delete their usernames.
- A username can help keep a phone number private from new contacts.
- A username key is available as an additional control over who can initiate contact.
WhatsApp usernames do not replace phone numbers as the underlying account registration requirement.
How Do WhatsApp Usernames Work for Businesses?
Once the feature becomes available for an account, the user can reserve or manage a username through WhatsApp’s settings. Meta’s instructions direct users to Settings → Account → Username to reserve a username on supported mobile versions. Availability can vary during the rollout.
The process is straightforward:
- Update WhatsApp to the latest available version.
- Check whether username reservation is available in the account settings.
- Choose an available username that follows WhatsApp’s rules.
- Set up an optional username key if additional control over first-time contact is needed.
- Share the username or a supported link or QR code when you want someone to contact you.
There is an important limitation: WhatsApp does not provide an open directory of usernames for people to browse. Someone generally needs to know your exact username to contact you for the first time.
WhatsApp Usernames vs Phone Numbers: What Is the Primary Difference?
The main difference is how people identify and contact one another.
Feature | Phone number | WhatsApp username |
Identification | Uses a phone number | Uses a unique handle |
First-time contact | A phone number can be shared | A username can be shared instead |
Privacy | Number may be visible to new contacts | Can hide the number from people who do not already have it |
Uniqueness | Phone numbers are individually assigned | Usernames must be unique |
Account registration | Required | Optional |
Discoverability | Can be contacted using a known number | Usually requires knowing the exact username |
Existing contacts who already have your number saved may continue to see it. A username therefore improves control over number sharing, but it does not make your WhatsApp account anonymous or guarantee complete privacy.
What Do WhatsApp Usernames Mean for Businesses?
WhatsApp usernames (@whatzcrm) can give businesses another way to present their identity and help customers start conversations without initially exchanging phone numbers.
Consider a small online store that wants customers to ask about product availability. A memorable business username could be included in its website, social media profile, product packaging, or other customer-facing materials.
Potential benefits include:
- Easier contact sharing: Businesses can provide a username as another contact option.
- Brand consistency: A recognizable username can complement an established business identity.
- Customer confidence: Some customers may feel more comfortable starting a conversation without immediately sharing their personal number.
- More flexible communication: Teams can review how they identify and manage customers across messaging channels.
However, a username should not be confused with a verified business identity or a guarantee of increased leads. Businesses still need accurate profiles, clear customer communication, and responsible messaging practices.
WhatsApp’s business username documentation also notes that the username and phone number can both appear on a business profile. Business owners should check the official requirements for their account type rather than assume that the same privacy behavior applies to personal and business accounts.
What Is BSUID in WhatsApp Business API?
BSUID stands for Business-Scoped User ID. It is a technical identifier relevant to WhatsApp Business Platform integrations and how businesses identify users when phone numbers are not available in the same way as before.
This matters for businesses using customer relationship management software, webhooks and automated messaging. If your system assumes every customer can only be identified by a phone number, your technical team should review how the integration handles the identifiers supplied by WhatsApp.
Businesses should check:
- Whether their integration supports the relevant WhatsApp user identifiers.
- How incoming webhook data is processed.
- How customer records are matched to existing conversations.
- Whether automation workflows depend exclusively on phone numbers.
- Whether the CRM provider has documented its support for username-related changes.
Do not assume that every WhatsApp CRM will stop working or lose messages because usernames exist. Actual impact depends on the integration, implementation and applicable WhatsApp Business Platform requirements. Consult the official WhatsApp Business username guidance and your provider’s documentation before making technical changes.
How Should Businesses Prepare for WhatsApp Usernames?
Preparation starts with understanding your current setup rather than rebuilding your entire marketing system.
- Review customer records: Check how your CRM stores contact identifiers, conversation history, and duplicate records.
- Audit integrations: Ask your WhatsApp Business API provider how it handles username-related identifiers and whether any configuration changes are needed.
- Test automated workflows: Review lead capture, chatbot handoffs, customer support routing, and follow-up sequences.
- Update contact-sharing instructions: Give sales and support teams clear guidance on how customers may contact the business using a username.
- Monitor results: Track inbound conversations, contact matching, unresolved messages, and duplicate records after relevant changes are introduced.
For teams managing a high volume of customer conversations, a WhatsApp CRM can help organize leads, assign conversations, and maintain follow-up processes. WhatZCRM offers features such as contact management, a unified team inbox, lead qualification, and automated follow-ups. Businesses should confirm their specific username and BSUID compatibility with the platform before relying on any feature for this use case.
How Can WhatsApp Usernames Affect WhatsApp Marketing?
WhatsApp usernames may change how some customers choose to initiate conversations, but they do not remove the need for permission-based marketing, relevant messaging or proper customer management.
Businesses can prepare by making their contact information easy to find, offering clear ways to start a conversation, and ensuring that new inquiries are routed to the right team.
For example, a business could use a WhatsApp contact option on a website to answer product questions, qualify potential leads, and direct inquiries to sales representatives. A CRM can help the team manage these interactions and schedule appropriate follow-ups.

Remember that a username alone does not guarantee better discoverability, higher engagement, or more conversions. Those results depend on the customer experience, the relevance of your offer, and the quality of your marketing.
