Effectively concealing all members in a Telegram group is a common request, especially for communities focused on sensitive topics or where members prefer anonymity.

Here's how Telegram's privacy features handle this in groups:

The Primary Method: "Hide Members" Feature (with a crucial condition)

Telegram has a built-in "Hide Members" feature that allows group administrators to conceal the list of members from regular group participants.

Steps to Enable "Hide Members":

Open the Telegram app and navigate to your group.

Tap on the group's name at the very top of the chat screen. This will take you to the group's info page.

Tap the "Edit" (pencil) icon in the top right corner.

Scroll down and tap on "Members".

Look for the option to "Hide Members" and toggle it on.

Crucial Condition:

This feature is only available for groups with 100 or more members. If your group has fewer than 100 members, the "Hide Members" option will not be available, and all members will be visible to each other.


Admins remain visible: Even when "Hide Members" is enabled, administrators of the group will still be visible in the members list to all participants.

What if your group has less than 100 members?

If your group does not meet the 100-member threshold, there is no direct official Telegram setting to hide all members from each other within a standard group. Members will always be able to see who else is in the group.

Alternative Approaches & Considerations for Privacy:
If hiding all members is paramount and your group is small, consider these alternatives or related privacy settings:

Telegram Channels:

Nature: Channels are designed for broadcasting messages to large audiences.

Member Visibility: In a channel, subscribers can never see who else is subscribed. Only the channel creator and administrators can view the subscriber list.

Interaction: The main drawback is that channels are primarily one-way communication. Only the channel owner/admins can post by default. While you can enable comments on posts, it's not the same as a free-flowing group chat.

Consideration: If your goal is to disseminate information while maintaining complete anonymity among recipients, a channel is the best solution.

Anonymous Group Admins:

This setting allows an administrator to post messages in a group as the group itself, rather than their personal account. This hides the admin's personal identity for specific messages.

How to Enable: In the group settings, go to "Administrators," tap on your name (or the admin you want to make anonymous), and toggle on "Remain Anonymous."

Limitation: This only hides the admin's identity when they post; it doesn't hide the general member list. Admins are still visible in the member list unless the "Hide Members" feature (for 100+ members) is active.

Encouraging Username Usage (instead of phone numbers):

While not directly "hiding" members, encouraging all members to set up a Telegram username (@username) and hide their phone number visibility improves overall privacy.

How to Hide Phone Number: Go to Settings > Privacy and Security > Phone Number. Set "Who can see my phone number?" to "Nobody" or "My Contacts."

Benefit: This prevents strangers in the group from seeing their phone number, adding a layer of privacy. Users can still be found and interacted with via their username.

Community Norms and Guidelines:

For smaller groups where visibility is unavoidable, establish clear community rules that discourage members from contacting each other privately without consent, or from using real names/personally identifiable information in their profiles.

In summary:

For Telegram groups with 100 members or more, you can enable the "Hide Members" setting in the group's edit options.

For groups with fewer than 100 members, Telegram does not offer a direct way to hide the member list.

If complete anonymity of members is critical regardless of group size, a Telegram Channel is the most suitable alternative, though it changes the interaction dynamic.
