WhatsApp Communities for business: how they work, the limits, and when to use one

You run a course with four cohorts, a building with six wings, or a business with separate groups for clients, suppliers and staff. Every time something changes, you paste the same message into six groups, and somebody still says they never saw it. Meanwhile each group fills up with off-topic chatter you have to wade through to find the two questions meant for you.

WhatsApp Communities for business solve the first half of that. A community puts related groups under one roof, up to 100 groups and 2,000 people, with an Announcements group where only admins post and every member receives it. Use a community when you run several groups for the same organisation and need one place for news; use a single group for one team or project; use a channel for one-way updates to an audience of any size; and use a broadcast list for a personal message to up to 256 contacts who've saved your number. The second half, reading everything that happens inside those groups, is where an assistant like Perisclaw helps.

How a WhatsApp community works

A community has two layers:

• The Announcements group: created automatically when you start a community. Every member is in it, only admins can post announcements and start polls, and members can reply and react. You can't leave it without leaving the whole community.

• The groups: ordinary WhatsApp groups that sit inside the community, one per topic, team, cohort or site. You can create new ones or add groups you already run. Members join the groups that matter to them, and each group keeps its own chat, events, polls and files.

Messages in communities are end-to-end encrypted, like the rest of WhatsApp.

WhatsApp Communities for business: limits and admin controls

As of November 2026, WhatsApp's help centre lists:

That last row catches a lot of small businesses out. If you use the WhatsApp Business app, you can't start a community there. You can still own one if someone transfers it to you, or if you created it on regular WhatsApp before registering that number as a business.

A few controls worth setting on day one:

• Who can add new groups: set it to Only community admins so members suggest groups and you approve them under Pending groups. Otherwise anyone can create a group inside your community.

• Join approval: group admins can require approval before someone joins a group that a member added, which matters for client or paid-member groups.

• Hidden groups: when an admin adds a group, they can set its visibility to hidden so members can't simply join it, useful for an admins-only or staff group.

• More admins: add a second admin so announcements don't stop when you're away. Note that community admins aren't added automatically to groups members create.

How to create a community

1. On regular WhatsApp, go to the Chats tab, open the new-chat menu and tap New community.

2. Tap Get started, then add a name (up to 100 characters), a description that tells people what the community is for, and an icon.

3. Add existing groups or create new ones. The Announcements group is created for you.

Then post your first announcement explaining which group is for what.

Community vs group vs channel vs broadcast list

How to choose:

• Use a group when everyone in it needs to talk: a client project, your ops team, one site.

• Use a community when you're running several of those groups for the same organisation and keep sending the same update to each. WhatsApp itself says using community announcements instead of repeated messages to groups may help reduce the risk of being flagged as spam.

• Use a channel for news to an audience that shouldn't talk back: customers following your launches, an industry newsletter, a public page. Followers don't see your profile name, photo or number.

• Use a broadcast list for a message that should land in each person's chat with you, like a holiday-hours note to regular customers. Only people who saved your number get it, broadcast lists work only from your phone, not WhatsApp Web or desktop, and some countries now have a monthly broadcast limit.

Keeping up with a community without reading every group

A community fixes the sending side. It doesn't fix the reading side: with five busy groups, you still miss the question addressed to you on Tuesday, the decision made in the staff group, and the complaint that got three agreeing replies.

Perisclaw is Your Executive Assistant on WhatsApp. It runs on your own number as a linked device, the same way WhatsApp Web does, so it can read the community groups you're in. You ask it in your self-chat, or type /claw inside a group.

What community owners ask it for:

• Catch-up after a day away: "Catch me up on the cohort groups: unanswered questions, decisions made, and anything that needs me personally." You get the questions with who asked, the decisions, and links back to the original messages.

• An evening report: "Watch the member groups. Every evening, send me repeated questions, unresolved complaints and threads going quiet." It keeps notes day to day, so it notices the same question for the third time this week, and flags anything urgent straight away instead of waiting for the report.

• Polls: "Poll the team group: Thursday 4pm or Friday 11am for the review call?" It posts a real WhatsApp poll and tells you who voted for what.

• A community FAQ that builds itself: react 📎 to a great answer a member posted and it's saved to your personal wiki. Later, "what did we tell people about pricing their first offer?" brings that answer back.

By default, anything Perisclaw writes to someone else on your request waits in your self-chat for your approval. It won't do bulk sending either: if you ask it to send the same message to many chats, it stops after 15 and asks before going further, and for genuine announcements it points you to a community, a channel or an opt-in group link instead.

One more caveat: Perisclaw connects as a linked device, which WhatsApp didn't build for outside tools, and WhatsApp's help centre warns that linking unofficial apps can lead to a ban. It takes one of your four linked-device slots, it's built for normal personal use, it adds at most 10 people to a group at a time and 20 in one turn (offering the invite link for more), and nobody outside WhatsApp can promise zero risk. If a group admin turns on WhatsApp's Restricted chat setting, they're asking that no outside tools or AI agents be used in that group, so block that group in Perisclaw's settings too.

FAQ

Can I create a WhatsApp community with the WhatsApp Business app?

Not as of November 2026. WhatsApp says you can't create a community from the Business app, but you can own one that's transferred to you, or one you created on regular WhatsApp before registering the number as a business.

How many people can join a WhatsApp community?

Up to 2,000 members in total, counting everyone in its groups and the announcement group, across up to 100 groups. Each group can have up to 1,024 members.

Can members reply to community announcements?

Yes. Members can reply and react, and admins get notified and can delete or report a reply, but replies can't be turned off. For updates with no replies at all, use a channel.

Should I use a WhatsApp group or a community for my business?

Use a group for one team or project where everyone talks. Use a community when you run several related groups and keep sending the same update to each of them.

What's the difference between a WhatsApp channel and a community?

A community is for members who talk in groups, with up to 2,000 people. A channel is one-way: unlimited followers, no replies, and followers can't see your name, photo or number.
