WhatsApp Communities are available to everyone after months in beta. Communities enable you arrange all your groups into organised discussion groups for various subjects or requirements. This functionality began testing this year.
Communities enable private clubs, schools, and organisations communicate and organise. You may now arrange and switch between various work-related groups.
Communities will have one primary announcement group for essential announcements, but only admin-approved subgroups may talk. This prevents spam from unrelated organisations.

Communities will include admin controls, sub-groups and announcement groups, 32-person audio and video conversations, greater file sharing, emoji responses, and polls to the chatting app. It supports 1024-member support groups and end-to-end encryption.
Once released, these functionalities will be accessible outside of Communities.
Communities and Facebook Groups enable sub-groups, file sharing, additional admin tools, and more. Since WhatsApp is phone number-based, WhatsApp Communities are more likely to be utilised by people who know each other in person than Facebook Groups.
Phone numbers will only be exposed to administrators and subgroup members.
Facebook Groups are discoverable whereas WhatsApp Communities are concealed. Invite-only. Admins may also migrate groups to Communities.
WhatsApp Communities will launch globally on Android and iOS devices in the coming weeks.
