What is a Telegram QR code and how it works
A Telegram QR code is a QR code that opens a Telegram channel, group, direct chat (t.me/username) or bot deep-link (?start=campaign) with a single scan from a phone camera. It stores the public t.me link so people can land straight on the right destination and join, message or start a bot on iOS, Android or a modern browser. The Telegram API documentation explains the supported deep-link formats for bot start parameters.
Add your logo, brand colours and AI-generated designs so the code matches your community identity, news channel, support flow or bot persona. Telegram introduced built-in QR support for adding contacts in its 2021 reactions and translations update. You can print it on conference badges, website footers, support flyers, course pages or event posters. Every scan appears in your dashboard, so you can compare channel, group and bot variants without reprinting.
