How to tell if a number is connected to WhatsApp Business API (WABA)?#
WhatsApp Business API (WABA) enables businesses to communicate with customers in an automated and scalable way via WhatsApp.
However, it is not always obvious whether a specific number is connected to WABA or is using the regular WhatsApp Business app.
Signs of WABA usage that can be identified through the app:
System notification in chat#
When a user opens a chat with a number connected to WABA, WhatsApp (Meta) displays an information notification at the top of the chat.
What does the notification look like?#
- Located at the top of the chat
- Looks like a green system message
- May be accompanied by a "Click to learn more"
This is the official indicator that messages in this chat are processed through the WhatsApp Business API infrastructure.
What does this notification mean?#
- The company's phone number is registered and verified in Meta Business Manager
- The company uses the WhatsApp Business API (not the WhatsApp Business mobile app)
- Correspondence is carried out via server integration
In this case, Meta is obliged to notify the user that their data is processed through an automated infrastructure - which is reflected in the system inscription.
Why is this important?#
For business: confirms that their channel is set up correctly and users see the WABA label.
For the user: increases trust and informs that the interaction is carried out with the official system, where personal data is processed in accordance with Meta policy.
For integrators: allows you to conduct an express audit of the visual design of the chat.
This is the easiest and most reliable way to verify a WABA connection, without access to internal information or API.
