Blocking a buyer stops them from bidding on your items or buying from you

When you block a buyer on eBay, that person can no longer purchase anything you list for sale. They also cannot bid on your auctions. If they try, eBay will reject their bid or purchase attempt automatically. Blocking is permanent unless you remove the block yourself later.

You block buyers through your eBay account settings, not through individual listings. Once blocked, the restriction applies to everything you sell going forward. eBay does not notify the blocked buyer that you have blocked them.

Most sellers block buyers after a bad transaction — unpaid invoices, returns with false claims, or hostile messages. Some block buyers preemptively if they see warning signs in their feedback or bidding history.

Key Takeaways

  • Blocking a buyer prevents them from purchasing any of your current or future listings on eBay.
  • You access the block feature through your Account settings under Seller preferences, not from the listing itself.
  • Blocks are permanent until you manually remove them, and eBay does not tell the blocked buyer why they were blocked.
  • You can block up to 1,000 buyers on a standard eBay account, and the block takes effect when ready.
  • Blocking does not refund money or resolve an active dispute — it only prevents future transactions with that person.

Where to find the block buyer feature

Log into your eBay account and go to Account. Select Seller preferences from the left menu. Scroll down until you see Block buyers. Click the Edit button next to it.

You will see a text box labeled "Enter usernames to block." This is where you type the eBay username of the person you want to block. You can add multiple usernames at once by separating them with a line break — one username per line.

If you are not sure of the exact username, search for the person's feedback page first. Their username appears at the top of their profile. Copy it exactly as it shows, including any numbers or special characters.

How to block a buyer step by step

Step 1: Sign into your eBay account and click Account at the top right.

Step 2: Select Seller preferences from the menu on the left side.

Step 3: Scroll down the page until you see a section called Block buyers. Click Edit.

Step 4: Type the username of the buyer you want to block into the text box. If you are blocking more than one person, press Enter after each username to put them on a new line.

Step 5: Click Save when you are done. eBay will confirm that the block is active.

The block takes effect when ready. If that buyer tries to bid on or purchase one of your listings within the next few minutes, the system will reject their action.

What happens after you block someone

Once blocked, the buyer will see an error message if they try to bid on your auction or buy your item. The message says something like "You are not able to bid on this item" or "This seller does not accept bids from you." It does not explain why.

The blocked buyer can still see your listings and your feedback. They just cannot complete a purchase. If you have an active dispute or unpaid case with them, blocking does not cancel it or refund any money — it only stops future transactions.

If you block someone by mistake or want to do business with them again later, you can remove the block. Go back to Seller preferences, click Edit next to Block buyers, find their username in the list, and delete it. Save your changes.

When blocking is useful and when it is not

Blocking works well for buyers who have a pattern of problems. If someone left you negative feedback unfairly, refused to pay, or sent hostile messages, blocking prevents them from doing it again. It is also useful if a buyer keeps bidding on your items and then canceling, or if they have a history of filing false return claims.

Blocking does not help if you are already in a dispute with someone. eBay will not remove a case or refund money just because you blocked the buyer. If you have an unpaid invoice, you still need to go through eBay's resolution process — blocking just prevents them from buying from you in the future.

You cannot block someone based on their location, feedback score, or the amount they bid. You can only block specific usernames. If a buyer uses multiple accounts, you would need to block each one separately.

How many buyers you can block and limits to know

A standard eBay seller account can block up to 1,000 different buyers. If you reach that limit, you would need to remove some blocks before adding new ones. Most sellers never come close to this number.

Blocks explore only to items you list for sale. They do not prevent the blocked buyer from leaving feedback on your past transactions or from messaging you through eBay's messaging system. If a blocked buyer sends you a message, you can report it to eBay, but the block itself does not stop the message from arriving.

Blocks are account-specific. If you have multiple eBay seller accounts, you would need to set up blocks separately on each one. A block on your main account does not carry over to a secondary account.

Removing a block if you change your mind

To unblock a buyer, follow the same path: Account, then Seller preferences, then click Edit next to Block buyers. Find the username you want to unblock in the list and delete it. Click Save.

Once you remove the block, that buyer can bid on and purchase your items again when ready. There is no waiting period. If you want to block them again later, you can add them back to the list.

eBay does not send a notification to the unblocked buyer. They will straightforward notice that they can bid on your items again if they try.

Frequently Asked Questions

Can I block a buyer if I am in the middle of a dispute with them?

Yes, you can block them at any time. However, blocking does not cancel the dispute or refund any money. You still need to go through eBay's resolution process to settle the case. Blocking only stops them from buying from you in the future.

Will the buyer know I blocked them?

eBay does not send them a notification. They will only know if they try to bid on or purchase one of your items and see an error message. The message does not say "you are blocked" — it just says they cannot bid on that item.

Can I block someone based on their feedback score or location?

No. You can only block specific usernames. If you want to avoid certain types of buyers, you can use eBay's buyer requirements settings instead, which let you set rules about feedback score, returns, or unpaid cases. Blocking is for individual people, not categories.

What if the buyer uses a different account to bid on my items?

You would need to block each account separately. If you notice the same person using multiple accounts to get around a block, you can report it to eBay. They may take action against the buyer for violating their policies.

Can I block someone from leaving feedback on my past sales?

No. Blocking only prevents future purchases. If someone left you feedback already, blocking does not remove it. If the feedback is unfair or violates eBay's rules, you can request that eBay remove it separately through the feedback resolution process.
