Telegram (also known as Telegram Messenger) is a cloud-based, cross-platform social media and instant messaging (IM) service. It launched for iOS on 14 August 2013 and Android on 20 October 2013. It allows users to exchange messages, share media and files, and hold private and group voice or video calls as well as public livestreams. It is available for Android, iOS, Windows, macOS, Linux, and web browsers. Telegram offers end-to-end encryption in voice and video calls, and optionally in private chats if both participants use a mobile device.
Telegram also has social networking features, allowing users to post stories, create public groups with up to 200,000 members, and share one-way updates to unlimited audiences in so-called channels.
Telegram was founded in 2013 by Pavel and Nikolai Durov. Its servers are distributed worldwide with several data centers, and its headquarters are in Dubai, United Arab Emirates. It was the most downloaded app worldwide in January 2021, with 1 billion downloads globally as of late August 2021. As of 2024, registration to Telegram requires either a phone number and a smartphone or one of a limited number of non-fungible tokens (NFTs) issued in 2022.
As of March 2025, Telegram has more than 1 billion monthly active users, with India as the country with the most users.
