One link format for people, channels, groups and bots
Telegram is unusually QR-friendly because everything shares one address shape: t.me/name works for a person, a public channel, a group and a bot alike. Encode the name and the code does the right thing for whichever kind of destination it is.
The most valuable placements are the ones where typing is hardest: a market stall sign pointing at your order channel, a poster for a community group, a sticker on equipment linking to a support bot. Telegram's deep links open the app directly, so there's no extra tap.
Two caveats worth knowing. Private groups use invite links with a random code rather than a username — paste those through "Any link" instead. And a name that looks free may be reserved through Fragment, so check before you print anything with it on.
Every Telegram code made here is static: the link lives in the pattern itself, with no redirect service in the middle that can expire, start charging or go down. There's no account, no watermark and no scan limit — download it once and it keeps working for as long as the Telegram link behind it does.
