How to Create a Channel in Slack (2026 Guide)
To create a channel in Slack, click the + next to “Channels” in the sidebar, choose Create a channel, name it, decide whether it should be public or private, and add people. Here is the full walkthrough for desktop, web, and mobile, plus naming tips and who is allowed to create channels.
1. Open the Channel Creator
On desktop or web:
- Find the Channels heading in the left sidebar.
- Hover over it and click the + icon (or click Add channels > Create a new channel).
On mobile (iOS/Android):
- Tap the new message / pencil icon, or go to the Home tab.
- Tap the + and choose Create a channel.
2. Name the Channel
Slack channel names have a few rules: lowercase only, no spaces, and up to 80 characters. Use hyphens to separate words.
#proj-website-redesign
#team-design
#help-it
#social-coffee-chatA consistent naming convention makes channels easy to scan. Many teams use prefixes:
proj-for projectsteam-for departmentshelp-for support channelssocial-for non-work chatter
Add a short description while you are here so anyone who lands in the channel understands its purpose. You can edit the name and description later from the channel’s settings.
3. Choose Public or Private
This is the most important decision, because it is hard to undo.
- Public channel (
#icon): Anyone in the workspace can find it in Browse channels, read its history, and join. Use this as your default; openness is part of why Slack works. - Private channel (lock icon): Invite-only and hidden from search for non-members. Use it for sensitive topics like hiring, finance, or leadership.
To make it private, switch on the Make private toggle in the create dialog. Note the one-way rule: you can convert a public channel to private later, but you cannot turn a private channel back into a public one. For a deeper walkthrough of the private path, see how to create a private channel in Slack.
4. Create the Channel and Add People
- Click Create.
- Slack prompts you to add people. You can:
- Type individual names to invite them.
- Add an entire user group (like
@marketing) at once. - Skip for now and add people later.
- For a public channel, you can also just share the channel link or tell people to find it in Browse channels and join themselves.
To add members after the fact, open the channel, click its name at the top, go to the Members tab, and click Add people.
5. Set Up the Channel for Its Job
Once created, a few touches make a channel more useful:
- Topic: A one-line status shown at the top (for example, a sprint goal or an on-call name).
- Pinned items: Pin the key doc or message so newcomers find it fast. See how to pin a message in Slack.
- Default channels: Admins can set certain channels so every new workspace member joins them automatically.
When a channel has served its purpose, you do not have to delete it; you can archive the channel to remove it from active lists while keeping its history searchable.
Who Can Create Channels in Slack?
By default, every full member can create public and private channels. Workspace owners and admins can restrict this:
- In Settings & administration > Workspace settings > Permissions > Channel management, owners can limit who creates public channels, private channels, or both.
- Guests (single- and multi-channel) generally cannot create channels.
- On Enterprise Grid, org admins can apply policies across all workspaces.
If you do not see the option to create a channel, your admin has likely restricted it; ask them to grant access or create the channel for you.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
