Zoom is a cloud-based video conferencing service offering HD video/audio calls, screen sharing, webinar hosting, breakout rooms, and recording. It supports business, education, telehealth, and conferencing across multiple platforms.

Zoom is accessible in China but only in a limited way: users can join meetings but cannot self-host unless using an approved business account or partner channel. Access to zoom.us is sometimes unstable, and features like cloud recording may not function reliably. Plugins and clients are available through 21Vianet‑licensed channels; international accounts can join meetings but often need business licensing to host. For full hosting capability, developers deploy Zoom for China via partners like 21YunBox.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
