Every group and channel you create on Telegram starts private. It has no address, it does not appear in search, and the only way in is an invite link you control or being added by a member.
Making it public claims a permanent handle and opens it to anyone who finds it. That switch is reversible, but the consequences of flipping it are not symmetrical — which is what this page is about.
What you will be able to do
- check_circle Tell what actually changes when a group goes public, beyond getting a link.
- check_circle Use invite links properly: revoking, expiring, and limiting how many people can use one.
- check_circle Put new members through an approval queue instead of letting a leaked link in.
- check_circle Know what happens to your handle if you switch back.
Group Type is the screen where both decisions live — the handle and the invite links are on the same page.
lock Private by default, and why that matters
Most platforms create spaces public and ask you to lock them down. Telegram does the opposite: a new group has no username, so there is no address to guess, nothing for a search engine to index, and no way to arrive without a link.
That makes the invite link the whole security boundary. It is a long random address rather than a guessable name, it can be revoked so a leaked copy stops working, and you can hand out several so you know which one leaked.
Four ways to let people in
These are not alternatives to each other — most groups end up using two or three at once for different audiences.

For anything not meant for strangers: private, with an approval queue on the link you publish.
settings Switching type
- Open the type screen Tap the group or channel header, then the edit pencil, then Group Type — Channel Type on a channel, Manage Group on desktop.
- Claim a handle, or do not Public Group asks for a username and checks availability as you type. Private keeps the random invite link instead.
- Add an approval queue if you need one Under the invite links, toggle Approve New Members on the link you intend to share.
- Consider content restrictions The same screen has Restrict Saving Content, which stops members forwarding messages out of the group.

| In-app search | Not found | Found by anyone |
| Search engines | Not indexed | Messages can be indexed |
| Joining | Link or invitation only | Anyone, unless approval is on |
| Undoing it | — | Handle is released to others |

This page is the switch and the links. The curriculum step covers the wider architecture: member visibility, what a broadcast group changes, and how handles are squatted and recovered.
