If you try to log in and see a message like «This phone number is banned», your account has been suspended or deleted. Most of these are false positives — legitimate accounts wrongly flagged by spam auto-detection — so if you used your account normally, an appeal can often get it back.
Quick answer (2026): To appeal a suspension, email recover@telegram.org, or use Settings → Help → Ask a Question in the app, or file through telegram.org/support. In the message, state your phone number and a legitimate reason for use in a few short, factual sentences. Replies usually take 3–7 business days; if there is no answer after 48 hours, sending a few polite follow-ups raises the odds your case reaches a human reviewer.
