The Telegram Gateway architecture checks whether the target phone number is registered on Telegram. If active, the code is dispatched into the user's dedicated Verification Codes service chat with an automated 1-tap copy button and self-expiring TTL. Businesses are billed strictly $0.01 only when the code is successfully delivered. If the user does not have a Telegram account, the API immediately returns status: "not_registered" at zero cost, allowing the enterprise to fall back to SMS.
