You can block someone on eBay in under a minute from your account settings

eBay lets you prevent a specific person from buying from you, selling to you, or contacting you through the platform. The block goes into your account settings and takes effect immediately — the person cannot see your listings, bid on your items, or message you. They will see an error message if they try to contact you, but they won't receive a notification that you blocked them.

Blocking is permanent unless you remove the block yourself. It applies only to your account, not across all of eBay, so the blocked person can still use eBay to buy and sell with other users.

Key Takeaways

  • Go to Account settings, then Blocking, and enter the username of the person you want to block.
  • A blocked person cannot bid on your items, buy from you, or message you, but they can still see your listings.
  • You can block up to 5,000 people on eBay, and the block takes effect right away.
  • If you change your mind, you can unblock someone by removing their username from the same Blocking page.

How to block someone step by step

Log into your eBay account and go to Account settings. You can find this by clicking your username in the top right corner and selecting Account settings from the dropdown menu.

Once you are in Account settings, look for the Blocking section in the left sidebar. Click on it. You will see a box that says "Block a user" with a text field underneath.

Type the eBay username of the person you want to block into that text field. Make sure you spell it exactly as it appears on eBay — usernames are case-sensitive. Click the Block button. The person is now blocked.

What a blocked person can and cannot do

A blocked person cannot place a bid on any of your active listings, cannot buy your items through Buy It Now, and cannot send you messages through eBay's messaging system. If they try to contact you, they will see a message saying they cannot reach you.

A blocked person can still see your listings and your feedback. They cannot see your email address or personal information, but they could theoretically contact you outside of eBay if they have your contact details from a previous transaction. Blocking only affects communication and transactions within eBay itself.

When you might want to block someone

Block a buyer if they have left you unfair feedback, sent you harassing messages, or made unreasonable demands about a transaction. Block a seller if they have sold you counterfeit or damaged items and ignored your attempts to resolve the problem, or if they have pressured you to communicate outside of eBay.

You might also block someone if they repeatedly bid on your items and then cancel their bids, or if they have engaged in shill bidding — placing bids on your own items to drive up the price. eBay's rules prohibit this, but blocking prevents them from doing it to you in the future.

How to unblock someone

Go back to Account settings and click Blocking. You will see a list of all the usernames you have blocked. Find the person you want to unblock and click the X button next to their name. They are now unblocked and can bid on your items and message you again.

There is no waiting period — the unblock takes effect immediately. If you unblock someone by mistake, you can block them again right away.

The difference between blocking and reporting

Blocking prevents someone from interacting with you, but it does not report them to eBay. If someone has violated eBay's rules — by sending threats, selling counterfeit items, or committing fraud — you should report them separately to eBay in addition to blocking them.

To report a user, go to their feedback page or the listing in question and look for a "Report this user" or "Report this item" link. Describe what happened and provide any evidence you have, such as messages or photos. eBay's Trust and Safety team will investigate. Reporting helps protect other eBay users from the same person.

Frequently Asked Questions

Can someone tell if I blocked them?

No. They will see an error message if they try to contact you or bid on your items, but eBay does not send them a notification that you blocked them. They may figure it out if they notice they cannot reach you, but eBay does not tell them directly.

How many people can I block?

You can block up to 5,000 people on eBay. Most users never reach this limit. If you are blocking large numbers of people, it may be worth reporting patterns of behavior to eBay instead.

If I block someone, will they still see my feedback about them?

Yes. Blocking prevents future contact and transactions, but it does not hide feedback that is already posted. If you left negative feedback before blocking them, they can still see it.

What if someone creates a new account to contact me after I block them?

eBay's rules prohibit evading a block by creating a new account. If someone does this, report it to eBay along with the usernames involved. eBay can take action against accounts used to circumvent blocks.

Can I block someone before I have a problem with them?

Yes. You might block someone if you have heard from other sellers that they are problematic, or if you want to avoid selling to a particular region or type of buyer. There is no rule against blocking someone preemptively.
