• Option B: Or type the full number directly into the search bar.

  
  

Step 4: View the Result

• If the number is registered on WhatsApp, you’ll see their profile, online status (if visible), and options to message or call.

• If not, you’ll see an “Invite to WhatsApp” option instead.

4. Search for the number: Look for the saved number in your WhatsApp contacts list.

5. Check for the green checkmark: If the number appears in your contacts and shows a green checkmark next to your sent message, it means the number is active on WhatsApp.

Additional Tips:

• Look for "Last Seen": If the number is on WhatsApp, you may see the “Last Seen” status, indicating when the user last used the app.

• Check for profile picture: You might also see the user’s profile picture if they have set one on WhatsApp.

• Try a WhatsApp call: Calling the person via WhatsApp and getting a connection or answer confirms the number is active on WhatsApp.
