How to block a buyer on eBay: Steps + limits (2026)

To block a buyer on eBay, sign in, open the Block bidders or buyers page, enter their username, and click Submit. This stops that account from bidding on or buying your items.

If someone keeps winning auctions without paying or sends abusive messages, blocking them can prevent another sale. Below, we’ll cover the steps, what happens after a block, and when buyer requirements or a report can help.

TL;DR

• You block a buyer on eBay by adding their username to your Blocked buyers list, which holds up to 5,000 names.
• A blocked buyer can’t bid on or buy your items. Adding them to your list also blocks regular messages, according to sellers in the eBay Community.
• eBay doesn't notify buyers when you block them.
• Buyer requirements block whole groups of risky buyers automatically, so you don't have to add names one by one.
• Blocking only protects your shop, so report buyers who break eBay's rules.

How to block a buyer on eBay in 4 steps

You block a buyer on eBay from the Block bidders or buyers page. It's a plain web page, so it opens in any desktop or phone browser. Here's the whole process:

1. Copy the buyer's username

Grab the exact username from the order, the auction's bid history, or your message thread. eBay's list only accepts usernames, so if you only have an email address, eBay's Bidder Block FAQ says you need to look up the user ID first.

2. Open the Block bidders or buyers page

Sign in and open the Block bidders or buyers page. You can also find it through eBay’s Blocking a buyer help article.

3. Enter the username and click Submit

Paste the username into the text box and click Submit. Blocking a few people at once? eBay's FAQ says you can separate names with a comma, a semicolon, a space, or a new line.

4. Check that your list saved

Read through the box once you've submitted and make sure every name is there and spelled correctly. If you delete a name by accident, click Restore list to bring back an earlier version of your list.

Pro tip: Blocking a bidder doesn't remove a bid they've already placed. If they're winning one of your live auctions right now, you have to cancel their bid yourself.

What happens when you block a buyer on eBay?

Once you click Submit, eBay stops that buyer from bidding on or buying anything in your shop. You don't need to name a listing. The block covers every current and future listing and starts right away, and your list can hold up to 5,000 usernames.

Here's what a blocked buyer can and can't do:

Blocked buyers can't message you anymore

In a September 2023 eBay Community discussion, sellers reported that adding someone to your Blocked buyers list also blocks their regular messages. The separate contact setting applies to buyers blocked by your buyer requirements.

Your messages can still reach the buyer, but their replies may not reach you. If you block someone while resolving an order problem, continue handling any open return or Item Not Received request through the case.

The same discussion confirms that choosing Block this member in eBay Messages also adds the person to your Blocked buyers list.

Blocked buyers don’t get a notification

No, eBay doesn't send blocked buyers an email or alert. They find out when they try to bid or buy and get an error saying you aren't accepting bids from them, as eBay Community mentors explain.

Blocked buyers can try to come back

Some blocked buyers open a second account to get around you. Doing that breaks eBay's Multiple accounts policy, so block the new username and report it.

When should you block a buyer on eBay?

Block a buyer when they've already cost you time or money, or when they've shown you they will. eBay lets you block anyone, for any reason. These are the situations where I'd add a name without a second thought:

• Unpaid items: They won an auction or hit Buy It Now, then never paid. If non-payers keep showing up, set buyer requirements (below) to block them automatically.
• Abusive or threatening messages: Block them, then report them. Nobody needs a second round of that.
• False claims or feedback threats: If you have evidence that a buyer is making a false claim or threatening negative feedback to get something you didn’t offer, report the behavior and consider blocking future purchases.
• Scam attempts: Requests to pay outside eBay or ship to a different address are classic red flags. Our guide on how to sell on eBay without getting scammed covers the rest.
• Bid-and-retract games: Someone who keeps bidding, then retracting, messes with your auction's final price. eBay counts this as reportable abuse, too.
• Endless lowball offers: A few blocks help, but you can also set auto-decline settings so eBay rejects lowball offers for you.

Can you block a buyer before they buy anything?

Yes. One seller with over 20 years on eBay asked about this in an eBay Community thread, and most replies backed the idea. One commenter added that the worst outcome is a lost sale.

But another seller pointed out that some of their best repeat buyers started out asking lots of questions. They'd been burned by bad listings before, and patient answers won their loyalty. So block on behavior, like rudeness or pressure, not on a hunch about a curious buyer.

Every block also shrinks your pool of buyers a little. If sales feel slow, start with these eBay selling tips before you start blocking.

How to set buyer requirements on eBay

Buyer requirements let eBay screen buyers against rules you choose, so you don’t have to add each account manually.

You can restrict buyers who:

• Have a delivery address in one of your excluded shipping locations
• Have a history of canceled orders because they didn't pay
• Are currently winning, or have bought, a set number of your items in the last 10 days

Those blocked buyers can still see your listings. They just can't bid or buy.

Set your buyer requirements in 5 steps

1. Go to Buyer Management while signed in.
2. Pick the requirements you want and fill in the details, like how many unpaid cancellations count against a buyer.
3. Select Apply above settings to active and future listings. Otherwise, your requirements will apply only to future listings.
4. Click Submit to save your buyer requirements.
5. To block messages from buyers restricted by these requirements, go to Site Preferences, select Don’t allow blocked buyers to contact you, and save the change.

Buyers may still contact you through an Item Not Received case or a return involving an existing transaction.

Exempt your loyal buyers

A trusted customer may meet one of your restrictions, such as the unpaid-order threshold you selected. Add their username to your buyer exemption list to let them buy despite that requirement.

To see who your rules have blocked, open your Buyer requirements activity log. It shows each username, the date, and the requirement that blocked them.

A note on excluded shipping locations

You set excluded locations in your shipping exclusions, either for all listings or one at a time when you list on eBay. If you use eBay International Shipping, eligible items may still ship through the program to locations you’ve excluded.

Blocking vs. buyer requirements: Which should you use?

Use both. Add the one person who already caused trouble to your Blocked buyers list, and use buyer requirements for the patterns you can predict. Here's how they compare:

Both tools are free, and you'll find them in eBay's Buyer Management settings. Want more help running your shop? In our roundup of eBay seller tools, we compare Seller Hub with paid options.

How to unblock a buyer on eBay

You can unblock a buyer at any time, and the change takes effect immediately. Here's how:

1. Go back to the Block bidders or buyers page.
2. Delete the buyer's username from the text box. Leave the other names alone.
3. Click Submit.

Once they're off your list, they can bid, buy, and message you again. According to eBay's FAQ, you can message the buyer after you remove them, so they know they can bid on your item.

When I'd unblock someone: You blocked the wrong account, a dispute ended fairly, or a buyer paid up and apologized. If the original problem could come back, keep the block.

How to report a buyer on eBay (and when to)

Report a buyer if you believe they’ve broken eBay’s rules. Include the relevant order details and messages so eBay can investigate and decide whether to take action on the account.

When to report instead of (or as well as) blocking

On its Report an issue with a buyer page, eBay lists these reasons:

• The buyer demands something your listing didn't offer
• You believe they're making a false claim
• They're misusing the eBay Money Back Guarantee or returns
• They asked you to complete the sale off eBay
• They keep bidding and retracting bids
• They message you far more than normal, with no plan to buy

How to report a buyer

1. Open your Orders list.
2. Choose Leave feedback from the dropdown next to the item, then select Report buyer.
3. Pick the reason and add the details, like dates, order numbers, and screenshots of messages.

You can also start a report from the Report a buyer button on eBay’s buyer reporting page. Keep your report factual. eBay can restrict accounts that intentionally submit false reports.

Order problems that need a case

If a buyer wants a return or says an item never arrived, work it out with them first. eBay gives you 3 business days to respond, then you can ask eBay to step in. eBay says it gets back to both of you within 48 hours.

Can buyers block a seller on eBay?

Buyers cannot block a seller in the same way sellers can. eBay doesn’t give buyers a Blocked sellers list, but you can hide a seller’s listings by entering their username under Sellers in Advanced Search and choosing Exclude.

If a seller keeps messaging you, use Block this member in eBay Messages to stop their messages. If they threaten you, offer to sell off eBay, or use abusive language, report the seller instead. If an item arrived damaged or never arrived, open a return or an Item Not Received request.

FAQs

1. Does blocking a buyer on eBay cancel their order?

No, blocking a buyer on eBay doesn’t cancel an order they’ve already placed, so you still need to ship any paid order. Bids they placed on a live auction before the block also stay active until you cancel them manually.

2. Can a blocked buyer buy from me with another account?

A blocked buyer can buy from you with another account, but doing so breaks eBay’s Multiple accounts policy. If you spot one, add the new username to your Blocked buyers list and report the buyer. eBay can restrict accounts that break the policy.

3. How many buyers can you block on eBay?

You can block up to 5,000 buyers on eBay through your Blocked buyers list. Buyer requirements have no list to fill, so eBay blocks every buyer who matches your rules, such as buyers with a history of unpaid-item cancellations.

4. Can you block a buyer from the eBay app?

Yes, you can block a buyer from the eBay app by choosing Block this member in eBay Messages, which also adds them to your Blocked buyers list. To block someone you haven’t messaged, open the Block bidders or buyers page in your phone’s browser.

5. Is it bad for your account to block buyers on eBay?

No, blocking buyers isn’t bad for your eBay account. eBay lets you block anyone for any reason. The only cost is fewer potential buyers, so save blocks for people who’ve caused trouble.
