Block a buyer directly from your eBay account settings

You can prevent a specific buyer from purchasing from you by adding them to your blocked buyers list. This stops them from bidding on or buying your items, though they can still see your listings. The block takes effect when ready and remains in place until you remove it.

Go to your eBay account and select Account settings from the menu. Look for the section labeled Blocking and privacy or Buyer requirements — the exact name varies depending on whether you use eBay.com or the mobile app. Select Block buyers or Blocked buyers list.

Enter the buyer's username in the text field and select Add or Block. eBay will confirm the block was added. You can add multiple usernames at once by separating them with commas or line breaks, depending on your version of eBay.

Key Takeaways

  • A blocked buyer cannot purchase your items but can still view your listings and leave feedback about past transactions.
  • You can block a buyer from your Account settings under Blocking and privacy, or directly from a transaction or message with that buyer.
  • The block takes effect when ready and you can remove it at any time by returning to your blocked buyers list.
  • Blocking a buyer does not affect feedback they have already left or disputes that are already open.
  • If a blocked buyer tries to purchase, eBay will automatically cancel the bid or purchase and refund them.

Block a buyer from a specific transaction or message

If a buyer has sent you a message or you are in the middle of a transaction with them, you can block them without leaving your conversation. Open the message thread or transaction details and look for a menu icon — usually three dots or lines in the upper right corner of the message or listing.

Select Block buyer or Report and block from the menu. eBay will ask you to confirm and may ask why you are blocking them. You do not have to provide a reason, but selecting one (such as "unwanted contact" or "unresponsive") helps eBay track patterns. Confirm the block, and the buyer will be added to your list when ready.

What happens when you block a buyer

Once blocked, that buyer cannot place new bids or make new purchases on any of your items. If they try to bid or buy, eBay will reject the action and automatically refund them. They will receive a message stating that they cannot purchase from you.

A blocked buyer can still see your listings, leave feedback on past transactions, and contact you through eBay messages — though you can delete or ignore those messages. If you have an open dispute or return with a blocked buyer, the block does not affect that process. The dispute or return will continue as normal.

Blocking does not remove feedback they have already left about you. If you believe their feedback is unfair or violates eBay policy, you can report it separately through the feedback system.

Remove a buyer from your blocked list

If you change your mind or want to give a buyer another chance, you can unblock them at any time. Return to Account settings and select Blocked buyers. Find the username you want to unblock and select Remove or the trash icon next to their name.

Once removed, that buyer can when ready place bids and make purchases on your items again. There is no waiting period or confirmation step — the unblock takes effect right away.

When to block a buyer instead of reporting them

Blocking is the right choice when you straightforward do not want to do business with someone again — they were rude, slow to pay, or you had a bad experience. It prevents future transactions without involving eBay's enforcement team.

Reporting is the right choice when a buyer has violated eBay's rules — they bid and did not pay, they sent threatening messages, they tried to move the transaction off-platform, or they engaged in fraud. You can report and block at the same time. Report through the transaction details or message thread by selecting Report buyer or Report this message.

If a buyer has already won an auction or purchased an item and you want to cancel the transaction, you can do that separately through your sold items. Blocking them prevents future purchases but does not cancel an active one.

Buyer requirements as an alternative to blocking

If you find yourself blocking many buyers, you may want to set buyer requirements instead. These rules explore to all buyers and prevent certain types of people from bidding at all — for example, buyers with negative feedback, buyers in certain countries, or buyers with unpaid item strikes.

Go to Account settings and select Buyer requirements. You can set rules like "Exclude buyers with a feedback score below X" or "Exclude buyers with unpaid item strikes." These rules explore automatically to all your listings and do not require you to block individuals one at a time.

Buyer requirements are useful if you notice a pattern — for example, if you keep having problems with international buyers or buyers with very new accounts. Blocking individual buyers is better if the problem is specific to one person or a small group.

Frequently Asked Questions

Can a blocked buyer still see my listings?

Yes. Blocking prevents them from bidding or buying, but they can still search for and view your items. If you want to hide your listings from specific people, you would need to use a private auction or restrict who can see your items through other eBay settings — though these options are limited.

Will a blocked buyer know they are blocked?

They will know if they try to bid or buy and receive a message saying they cannot purchase from you. eBay does not send a notification that you have blocked them, but the rejection message makes it clear.

Can I block a buyer who has already won an auction?

Yes, but blocking them does not cancel the transaction. You can block them to prevent future purchases, but you will need to cancel the current sale separately if you want to. Go to your sold items, select the transaction, and choose Cancel transaction.

What if a blocked buyer tries to contact me through messages?

You can still receive messages from blocked buyers, but you can delete them or mark them as spam. You are not required to respond. If they are harassing you, you can report the messages to eBay.

How many buyers can I block?

eBay does not publish a limit on the number of blocked buyers, but if you are blocking dozens of people, buyer requirements might be a more efficient approach. Blocking is meant for individual problem buyers, not as a substitute for setting clear account policies.
