For years, joining a WhatsApp call required everyone involved to have an account on the messaging platform. That requirement often complicated communication with colleagues, clients, students or relatives who preferred other applications.
Now, WhatsApp is removing that barrier. With the introduction of WhatsApp guest calling, people can participate in one-on-one and group calls without registering for the service, downloading the application or providing a WhatsApp phone number.
Instead, guests can open an invitation link through a supported computer browser, enter their name and request permission to join.
The development marks a significant expansion of WhatsApp’s calling capabilities as the Meta-owned platform positions itself as a more flexible communication tool for personal, educational and professional use.
How WhatsApp Guest Calling Works
The new feature builds on WhatsApp’s existing call-link functionality, making it possible for account holders to invite people outside the platform.
To create a guest call, a WhatsApp user opens the application’s Calls tab, selects the plus (+) icon and generates a call link. That link can then be shared with colleagues, classmates, business partners, family members or anyone else the host wishes to invite.
Recipients without WhatsApp accounts simply open the link in their computer browser and enter a display name. However, joining is not automatic.
Guests are placed in a virtual waiting room until the call host approves their request. Once admitted, they can participate in the conversation alongside regular WhatsApp users.
Only people with registered WhatsApp accounts can create call links, meaning guest access is designed for joining existing conversations rather than independently hosting them.
Free Encrypted Calls With Up to 32 Participants
One of the most notable aspects of WhatsApp guest calling is its support for group conversations involving up to 32 participants. This makes the feature potentially useful for small businesses, project teams, study groups and community organisations.
WhatsApp also says guest calls have no time limits, removing the concern of meetings ending automatically after a predetermined duration. Participants can continue their conversations without having to restart sessions or distribute new invitation links because a time allowance has expired.
Importantly, WhatsApp says the calls remain end-to-end encrypted, extending its existing privacy protections to guest participants. This means call content is protected by encryption rather than being made accessible simply because someone joins without an account.
For organisations handling sensitive discussions, however, encryption should still be accompanied by appropriate meeting controls and responsible information-sharing practices.
Additional Privacy Controls
Allowing people without accounts into conversations naturally raises questions about privacy and security. WhatsApp has addressed some of these concerns through a collection of guest-specific restrictions.
Every guest must receive approval from the call host before entering a conversation. Hosts can also remove guest participants whenever necessary. Additionally, guests cannot view other participants’ phone numbers, send messages within the call or directly invite additional people.
These restrictions are particularly relevant for professional meetings where participants may not know one another.
For example, a Ugandan business owner hosting a discussion with several potential clients could invite them without automatically exposing their contact details to other guests. The waiting room also gives hosts greater control over who participates, although they must still verify the identity of unfamiliar attendees.
Screen sharing and reactions make Guest Calls more useful
WhatsApp guest calling is not limited to basic voice and video communication. Guest participants can access several essential meeting features, including computer screen sharing.
This allows users to present documents, demonstrate software, review assignments or collaborate on projects during conversations. Guests can also react using emojis, including a thumbs-up or heart, and raise their hands when they wish to contribute.
These capabilities bring WhatsApp closer to the familiar experience offered by dedicated video conferencing platforms.
For students, screen sharing could simplify remote tutoring sessions. For businesses, it could support presentations, customer consultations and collaborative discussions without requiring every participant to install another application.
