End-user: block a single number from the Zoom app (quick, per-caller blocking)

If you (or a queue member) see a number in history and want to block it immediately:

Desktop / Mobile app:

1. Open the Zoom desktop or mobile app and click Phone.

2. Go to History, Voicemail, or SMS tab and find the number.

3. Click the three-dot More icon to the right of the entry → Block Number → choose reason (Spam / Other). Zoom

Web App:

1. Sign in to the Zoom Web App → Phone → SMS tab.

2. Use the more options icon next to a number → Block Number. Zoom

Note: App blocking is per-user (it blocks the caller from reaching that user), not necessarily global.
