Problem

You may want to stop someone from messaging or calling you on Telegram without deleting your account. Later, you might decide to unblock them.

Solution

Telegram lets you block users so they can’t send you messages, see your last seen, or call you. You can unblock them anytime.

Optional Methods or Tools

• When blocking, you can also report spam — Telegram forwards the report for review.
• On Telegram Desktop/Web, blocking/unblocking works the same way under Settings > Privacy and Security.

Best Practices / Tips

• When you block someone:
  • They can’t see your last seen, online status, or profile updates.
  • Their messages won’t deliver (only one check mark).
• Blocking doesn’t delete old chats — you can manually clear the conversation if desired.
• You won’t receive calls or notifications from blocked users.
• If harassment continues via new accounts, restrict who can see your phone number in Privacy settings.
