User Info Bot

Nearly every Telegram bot integration eventually needs a raw numeric ID — a user_id to check against an allow-list, a chat_id to send a message to via the Bot API, or a file_id to reference a sticker. User Info Bot is built around exactly that need: send /start to see your own ID, forward a message to see the sender's, or forward a sticker to get its file identifiers.

What makes it one of the most-used tools of its kind (its own profile shows well over half a million monthly users) is that it asks for nothing beyond the forward itself — no account, no bot token, no configuration. It reads only what is inside the forwarded message and returns the IDs Telegram itself assigned, which makes it safe to hand to a teammate who just needs a chat ID once and will never touch it again.

It covers users, bots, groups, channels and stickers, making it a broader Swiss-army version of the many single-purpose 'get my ID' bots that exist. For anyone building against the Telegram Bot API, this is usually the fastest way to get the numeric identifiers real code needs.
