What are Telegram sticker collections called?

Telegram sticker collections are called packs.

Telegram introduced stickers as a more expressive alternative to ordinary emoji. Each pack groups related images—often built around a character, artist, meme, or theme—and users can add packs to their sticker panel for quick access in chats.

A common source of confusion is Telegram’s technical terminology. The user-facing concept is generally described as a “sticker pack,” while Telegram’s API and some interface documentation also use “sticker set.” Those terms refer to the same broad collection concept in ordinary quiz usage, but “packs” is the expected answer here.

Telegram stickers are cloud-based and synchronize across a user’s logged-in devices. They began as static images, later gained animated formats, and were followed by video stickers and custom emoji. Users can also create and share their own themed collections.
