The quickest way to block a user

Open Instagram and find the account you want to block. This can be their profile page, a comment they left on your post, or a message they sent you. Tap the three dots (or three lines) in the top right corner of their profile or next to their name. Select "Block" from the menu that appears. Instagram will ask you to confirm — tap "Block" again, and the person is blocked when ready.

The person you blocked cannot see your profile, posts, stories, or follower list. They cannot message you, and any existing messages between you stay in your chat history but cannot be opened. If they search for your account, they will see a message saying the user is not found or the account is private — they will not see a notification that you blocked them, though they may figure it out by trying to visit your profile.

Blocking takes about five seconds and works the same way whether you are on the Instagram app or using Instagram through a web browser on a computer.

Key Takeaways

  • You can block someone from their profile, from a comment they made, or from a direct message by tapping the three dots and selecting "Block".
  • A blocked person cannot see your posts, stories, profile, or messages, and cannot send you new messages.
  • The person you block will not receive a notification that you blocked them, but they may notice they cannot find your profile.
  • You can unblock someone at any time by going to your settings, finding the blocked accounts list, and tapping "Unblock".
  • Blocking is different from muting — a muted person can still see your posts and profile, but their posts and stories will not show up in your feed.

Blocking from someone's profile page

Go to the person's Instagram profile by searching for their username or tapping their name from a comment or message. Once you are on their profile, tap the three dots in the top right corner (on mobile) or the three lines (on a computer). A menu will appear with several options. Tap or click "Block" near the bottom of the menu.

Instagram will show a confirmation screen explaining what blocking does. Read it if you want to be certain, then tap "Block" again to confirm. The person's profile will disappear from your screen, and the block is now active.

Blocking someone from a comment or message

If someone has left a comment on your post that you want to block them for, tap the three dots next to their comment. You will see options including "Block" — tap it and confirm. The comment will disappear from your post, and the person is blocked.

If you want to block someone who has messaged you, open the direct message thread with them. Tap the person's name at the top of the conversation. A profile preview will open. Tap the three dots in the top right, then select "Block". You can also swipe left on their message thread (on iPhone) or long-press it (on Android) to see a "Block" option without opening the conversation.

What happens after you block someone

The blocked person loses access to everything about you on Instagram. They cannot see your profile when they search for you — the search result will say "User Not Found" or show your account as private even if it is public. They cannot see your posts, stories, reels, or any content you have shared. If they try to message you, the message will not go through, and they will not know why.

Any direct messages you had with them before blocking will still be in your chat history, but they cannot open them or send new ones. If you had liked or commented on their posts before blocking, those interactions remain visible to other people, but they cannot see that you did it.

The blocked person will not see a notification saying you blocked them. However, if they try to visit your profile or search for you and cannot find you, they may suspect you blocked them. There is no way to hide the fact that you blocked someone if they actively look for your account.

Unblocking someone later

If you change your mind, you can unblock someone at any time. Go to your profile and tap the menu icon (three lines) in the top right. Select "Settings and privacy", then "Blocking". You will see a list of all the accounts you have blocked. Find the person you want to unblock and tap "Unblock" next to their name. Confirm when Instagram asks you to.

Unblocking someone does not automatically follow them or restore old messages. They will not be notified that you unblocked them. Once unblocked, they can see your profile and posts again, and you can message each other normally.

Blocking versus muting and reporting

Blocking is the strongest action you can take against someone on Instagram, but it is not the only option. Muting someone hides their posts and stories from your feed without them knowing, but they can still see your profile and posts if they visit it. Muting is useful if you want to avoid seeing someone's content but do not need to cut off contact completely.

Reporting is different from blocking. You report someone when they have broken Instagram's rules — harassment, hate speech, spam, or explicit content. Reporting sends the content to Instagram's team for review. You can block and report the same person, and you should report if their behavior violates Instagram's community guidelines, even if you also block them.

You can also restrict someone, which is less visible than blocking. A restricted person can still see your profile and posts, but their comments on your posts will only be visible to them, and you will not see their messages in your main inbox.

Frequently Asked Questions

Will the person know I blocked them?

They will not receive a notification. However, if they try to find your profile and cannot, or if they notice they can no longer see your posts, they may figure it out. There is no way to block someone invisibly if they actively look for your account.

Can I block someone without them seeing that I unfollowed them first?

Blocking automatically unfollows the person, so they will not see you in their follower list. If they check your follower list before you block them, they will see you are gone, but blocking happens when ready and they will not receive a notification about it.

What if I block someone and then unblock them — will they know?

No. Unblocking does not send a notification. They will only know if they try to visit your profile while you have them blocked, notice they cannot, and then try again later and find they can.

Can I block someone on Instagram if they have a private account?

Yes. You can block anyone on Instagram regardless of whether their account is public or private. The blocking process is the same.

If I block someone, will they still be able to see old comments I made on their posts?

Yes. Any comments or likes you left before blocking them will still be visible on their posts. Blocking only prevents future interaction and hides your profile from them going forward.
