How to make a Telegram QR code
Type your Telegram username, a public channel name or a public group name, with or without the @. You can also paste a full t.me link. The code opens a t.me address, and Telegram opens your chat, channel or group so the person can message you or tap Join.
The Auto logo shows the blue Telegram plane, and the label starts as Message us. For a channel, Join our channel is clearer.
Telegram channel QR code for teachers and creators
Tuition centres and teachers use Telegram channels to share notes, past papers and class updates. Printing a channel code on the notice board or the first page of a handout lets students join in seconds. News pages, deal channels, book clubs and job alert groups use it on posters and in videos.
For a public channel, the username after t.me is all you need. For a private group, paste the full invite link instead.
Telegram group QR code for communities
Housing society groups, alumni groups and event volunteer groups can put a code on a gate notice or a registration desk. New members scan and land in the group directly, instead of searching for a name that may be spelt three ways.
Be careful with private invite links in public places. Anyone who scans can join. If the group should stay small, share the code only on paper that goes to the right people, and remember you can reset the invite link in Telegram, which stops the old code working.
Size and design tips
A t.me link is short, so the code stays simple and scans well at small sizes. About 2 cm wide is fine on a card. For a classroom wall, print larger so students can scan from their seats. Blue on white matches the Telegram style and reads well.
On a printed handout, add the channel name in words under the code. Students who cannot scan in class can then search for it later. If you run several channels, for example one per class or subject, change the label on each code so they are easy to tell apart on the notice board.
For a slide or a video, keep the code on screen long enough for people to unlock their phones and open the camera. A few seconds is rarely enough; ten seconds or more is kinder, and saying the channel name out loud helps too.
Telegram QR not opening the right chat?
- Check the username spelling; Telegram usernames are not case-sensitive, but underscores matter
- A private channel has no username, so use its invite link
- If the person does not have Telegram, the link opens a page asking them to get the app
If you are not sure whether your username is set, open Telegram settings and look under your name. Without a username, people cannot reach you from a link, so set one first and then come back to make the code. It takes a minute and you can pick a name that matches your shop or channel.
