Block someone on OfferUp directly from their profile or a conversation

You can block another OfferUp user in two ways: from their profile page or from a message thread with them. Both methods take about 30 seconds and prevent that person from contacting you, viewing your listings, or sending you offers. The blocked user will not receive a notification that you blocked them, but they will no longer see your profile or items for sale.

Blocking is permanent until you manually unblock the person. If you block someone by mistake, you can reverse it by going to your blocked users list and tapping the unblock option next to their name.

Key Takeaways

  • You can block someone from their profile by tapping the three-dot menu and selecting "Block User," or from a message thread by tapping the menu at the top.
  • A blocked user cannot message you, see your listings, or make offers on your items, but they can still see your profile if they search for it directly.
  • OfferUp does not notify the blocked person, and blocking does not delete past messages or transactions between you.
  • You can view your full list of blocked users in your account settings under "Blocked Users" and unblock anyone at any time.
  • If someone is harassing you, take screenshots of the messages and report them to OfferUp support in addition to blocking them.

Block someone from their profile

Open the OfferUp app and search for or navigate to the person's profile. Tap the three vertical dots (the menu icon) in the top right corner of their profile. A dropdown menu will appear with several options. Select "Block User" from the list.

A confirmation message will appear asking if you are sure you want to block this person. Tap "Block" to confirm. The person is now blocked and cannot contact you or see your listings.

Block someone from a message conversation

Open the OfferUp app and go to your Messages tab. Find the conversation with the person you want to block and tap on it to open the thread. At the top of the conversation, you will see the person's name and a three-dot menu icon on the right side. Tap that menu icon.

Select "Block User" from the options that appear. Confirm the action when prompted. The conversation will remain in your message history, but the person cannot send you new messages or contact you through OfferUp.

What happens when you block someone

Once you block a user, they cannot message you through OfferUp, make offers on your items, or see new listings you post. However, they can still view your profile if they search for your username directly — blocking only prevents them from contacting you and seeing your active inventory.

Past messages and transaction history between you and the blocked person remain in your account, but the blocked user cannot see them or access your profile through normal browsing. If the person tries to message you or view your listings, they will see an error message indicating they cannot perform that action.

View and manage your blocked users list

To see everyone you have blocked, open the OfferUp app and tap your profile icon at the bottom right. Go to Settings, then scroll down and tap "Blocked Users." This page shows a list of every person you have blocked on OfferUp.

To unblock someone, find their name in the list and tap the "Unblock" button next to it. Confirm the action. Once unblocked, that person can message you and see your listings again. You can block and unblock the same person as many times as you need to.

Report harassment in addition to blocking

If someone is sending you threatening messages, asking you to move off the platform, or behaving abusively, blocking alone may not be enough. Take screenshots of the problematic messages and report the user to OfferUp support. Open the conversation, tap the three-dot menu, and select "Report User." Describe what happened and attach your screenshots.

OfferUp's support team reviews reports and can suspend or remove users who violate the platform's terms of service. Reporting creates a record with the platform and helps protect other users from the same person. You can block and report someone at the same time.

Blocking on the OfferUp website versus the app

Most OfferUp users buy and sell through the mobile app, which is where blocking works most smoothly. If you use the OfferUp website on a computer, you can still block users, but the process is slightly different. Visit the person's profile, click the three-dot menu, and select "Block User."

Blocking on the website and in the app are linked to the same account, so if you block someone through the website, they are blocked in the app as well. Your blocked users list syncs across both platforms, so you only need to manage it in one place.

Frequently Asked Questions

Will the person know I blocked them?

No. OfferUp does not send a notification when you block someone. The person will only know if they try to message you or view your profile and see an error. They may suspect they are blocked, but OfferUp does not tell them directly.

Can I block someone who already bought from me?

Yes. You can block anyone on OfferUp at any time, regardless of whether you have completed a transaction with them. Past messages and transaction history will remain in your account, but they cannot contact you or see your future listings.

What if I block someone by mistake?

Go to your Settings, tap "Blocked Users," find the person's name, and tap "Unblock." They will immediately be able to message you and see your listings again. There is no penalty for unblocking someone.

Does blocking delete our past messages?

No. Blocking does not erase your message history with that person. The conversation remains in your Messages tab, but the blocked user cannot see it or send you new messages. You can still read what was said before you blocked them.

Can a blocked person still see my listings if they search for them?

A blocked user cannot see your profile or items through normal browsing or search. However, if they know the exact item name or listing number, they may be able to find it through a direct search. Blocking prevents them from accessing your profile, which is the main barrier.
