Telegram Lookup by Phone Number
View All Telegram Number Validation & Profile Lookup APIs →Check whether a phone number is registered on Telegram and, when registered, return its public profile in one call: username, display name, About bio, Telegram user ID, common-chats count, phone/video call availability, last-seen timestamp (Unix seconds), and flags (premium, verified, bot, scam, fake, deleted, restricted, inactive). Pass the full international number (digits, with country code); the API normalizes to digits only. When the number has no Telegram account, registered=false is returned.
