Blocked Bidder List Ebay

How to find and use the blocked bidder list on eBay

Last updated: August 2026

Bottom line: the blocked bidder list eBay gives every seller holds up to 5,000 usernames, and for most sellers fewer than 20 entries handle every genuinely problematic buyer they'll meet in a year. It lives in your account settings under Site Preferences rather than anywhere in Seller Hub, which is why sellers hunt for it and conclude it doesn't exist.

Blocking is instant, reversible, and silent — the buyer isn't notified, they simply find they can't bid or buy from you.

The feature does two separate jobs that get conflated. One is the manual list, where you paste in specific usernames.

The other is Buyer Requirements, a set of automatic rules that block whole classes of buyer without you naming anyone: people with unpaid item strikes, people in countries you don't ship to, people with a feedback score of -1 or lower, people without a payment method on file.

Sellers who only use the manual blocked bidder list eBay provides are doing by hand what the rules would do continuously.

What blocking does and doesn't stop

A blocked buyer can't bid on your auctions or complete a purchase on your fixed-price listings. That's the whole of it. They can still see your listings, still watch them, and depending on your message settings may still be able to contact you.

Blocking is not a report — it changes nothing about that buyer's standing with eBay and doesn't feed into any enforcement action. If someone has actually violated policy, blocking them protects you but reporting them is the separate step that does anything about it.

The economics are worth a moment. A single unpaid item on a $120 auction costs you the relisting time, the delay in recycling that capital, and often a second-chance offer at a lower price — realistically $15 to $40 of value on a mid-priced item, plus the aggravation. Against that, adding a username to the list takes about fifteen seconds.

Sellers who treat the list as a running record rather than an emergency measure spend a few minutes a month and stop repeating the same problem.

One caution: the list is a blunt instrument and it's permanent until you edit it. Blocking a buyer over a single slow payment removes them from your market forever, and buyers do change habits.

How to handle the blocked bidder list questions that come up most

Bottom line: nine questions cover almost everything sellers need here, and the two that cause real damage are what blocking doesn't do and what happens to bids that are already placed. The mechanics are simple enough that the mistakes tend to be about expectations rather than clicks.

Where exactly is the blocked bidder list on eBay?

It sits in your account settings, not in Seller Hub, which is the single most common reason sellers can't find it. The path runs through My eBay to Account, then Site Preferences, then the Buyer Requirements area, where you'll find the option to block buyers from bidding on or buying your items.

That placement makes a certain sense — it's an account-level rule rather than a listing tool — but it means the blocked bidder list eBay maintains for you is invisible from the screens where you spend your working day. Bookmark the page the first time you find it.

How many usernames can the list hold?

Up to 5,000. In practice, nobody approaches that. A seller moving 200 items a month typically accumulates somewhere between 10 and 30 entries across several years, because genuinely problematic buyers are rare and most friction turns out to be a misunderstanding rather than a pattern. The 5,000 ceiling exists for high-volume operations dealing with organised abuse.

If your own list is growing past a couple of dozen names a year, that's usually a signal about your listing terms or your category rather than about buyers.

Does blocking cancel bids that are already placed?

No, and this is the one that costs money. Adding someone to your blocked bidder list eBay-side stops future bids and purchases, but any bid already sitting on your auction stays there. If that buyer is the high bidder when the auction ends, you have a sale to someone you just blocked.

Cancelling an existing bid is a separate action taken on the listing itself, and it has its own rules and time limits near the end of an auction. Block and cancel are two steps, not one.

Will the buyer know they've been blocked?

Not directly. There's no notification and no badge. A blocked buyer who tries to bid or buy sees a message saying they can't complete the action on that seller's items, which is informative enough that a determined person works it out, but there's no announcement.

Practically speaking, most blocked buyers never notice, because most of them weren't planning to come back anyway. Sellers sometimes worry about retaliation here; in the ordinary case there's nothing to retaliate against, because nothing visible happens. , according to IBISWorld industry reports

Can a blocked buyer still message me?

By default, often yes. Blocking governs bidding and buying, not communication. There's a separate setting controlling whether blocked buyers can contact you, and sellers who block someone over harassment rather than payment behaviour should make sure that box is ticked as well.

Leaving it unticked is how a seller ends up believing the block failed — the purchases stopped, but the messages kept arriving, which feels like nothing changed.

What's the difference between the manual list and Buyer Requirements?

The manual blocked bidder list eBay stores is a named list of individuals. Buyer Requirements are standing rules that filter classes of buyer automatically: those with unpaid item cancellations on record, those with a feedback score of -1 or lower, those in locations you don't ship to, those without a payment method on file.

The rules do continuous work without you knowing any names, which is why they prevent far more trouble than the list does. Most sellers should configure the rules once and use the list only for specific individuals who slip through.

Should I block a buyer over one slow payment?

Usually not. Blocking is permanent until you edit it, and it removes that person from your market forever. Consider what a customer is worth: a repeat buyer in women's outerwear might spend $300 to $600 with you over a couple of years, and one late payment on a $45 item is a poor reason to forfeit that.

We see operators block reflexively after a bad week and then quietly wonder why a category went soft. Reserve it for non-payment that repeats, abusive messages, and returns behaviour that reads as deliberate.

Does blocking protect me from scams and fraudulent returns?

Only after the fact. A blocked bidder list eBay keeps for you is a memory of problems you've already had; it does nothing about a first-time bad actor, and organised fraud rarely reuses an account you've already met.

Treat it as one layer among several — clear listing photos, accurate condition notes, tracked shipping on anything above about $50, and prompt reporting of genuine policy violations. The list is the cheapest layer, not the strongest one.

How do I unblock someone?

Edit the list and remove the username. The change takes effect immediately and there's no cooling-off period, so a block applied in anger can be undone within a minute.

This is worth knowing precisely because blocks are otherwise permanent by default — nothing expires on its own, and a name added five years ago is still filtering that buyer today unless you go and look.

A note on record-keeping

Keep a short note of why each name went on. Six months later, "why is this person blocked" is unanswerable from the list itself, which stores usernames and nothing else.

A two-line record in the same spreadsheet where you track orders costs nothing and saves you from either unblocking a genuine problem or keeping out a customer who did nothing wrong.

Quick tangent — I use the Closo Seller Hub to track what is actually moving right now, which saves me about three hours a week of manual search. Worth a peek before your next haul.

How to use blocking as a policy rather than a reflex

Bottom line: sellers who configure Buyer Requirements once and block fewer than five individuals a year consistently report less friction than sellers with 200-name lists, because the automatic rules catch risk before it becomes an incident while a long manual list mostly records old grudges. The difference isn't temperament, it's sequencing — one group set a policy, the other reacts case by case.

Think about what a block actually costs you. On a category with any repeat-purchase behaviour, a buyer is not a single transaction. Someone who bought a $40 jacket may well be back for three more over two years, and the lifetime value of that relationship sits somewhere around $150 to $200 in gross terms.

Every name on the blocked bidder list eBay keeps for you is that value written off permanently, in exchange for avoiding one repetition of whatever went wrong. That trade is obviously correct for a buyer who sent abusive messages and obviously wrong for one whose payment arrived three days late during a holiday week.

The interesting cases are in between, and the way to handle them is to decide in advance rather than in the moment. , according to U.S. Census Bureau economic data

A workable policy looks roughly like this: automatic rules handle payment risk and geography, so you never have to think about them; the manual list is reserved for behaviour rather than outcomes. Non-payment once is an outcome — annoying, cheap, forgettable. Non-payment twice from the same account is behaviour.

A return that arrives with the item swapped is behaviour on the first occurrence, and belongs on the list immediately. Framing it that way keeps your blocked bidder list eBay-side short, defensible, and free of names you can no longer explain.

What the long lists have in common

When we look at operations carrying hundreds of blocked usernames, the pattern is nearly always the same and it isn't about difficult buyers. It's listings that invite disputes: photographs that hide a flaw, condition notes that say "good" where "visible wear on the left cuff" was the truth, or shipping estimates that were never realistic.

A seller who describes a $95 handbag as excellent and ships it in a reused mailer generates disputes at a rate no blocking policy can absorb, and each dispute produces a name for the list. The list grows, the underlying problem doesn't move, and the seller concludes that eBay's buyers are the issue.

The diagnostic is simple. Pull your last fifty transactions and count how many produced friction. If it's above roughly one in ten, the fix is in your listings, not your blocking. If it's one in fifty, your blocking policy is fine and the occasional bad actor is just the cost of doing business in a marketplace with 130-odd million buyers.

One more structural point: the blocked bidder list eBay holds is per-account, not per-listing and not per-marketplace. A seller running eBay alongside Poshmark or Mercari has no shared blocklist across them, and the same buyer can reach you on another platform freely.

If someone's behaviour was serious enough to block, note it in your own records rather than trusting any single platform's list to protect you everywhere.

How to set this up once and stop thinking about it

Bottom line: fifteen minutes spent configuring Buyer Requirements today prevents most of the incidents that would otherwise put names on your list over the next year — and unlike blocking, it costs you no customers you'd have wanted. Open Site Preferences, turn on the rules that match your operation, and check the blocked bidder list eBay already holds for you while you're there.

Three settings do most of the work. Block buyers with unpaid item cancellations on record, because that's the single behaviour most predictive of it happening again. Block buyers in countries you don't ship to, which prevents the awkward cancellation that costs you a defect rather than just a sale.

And decide deliberately whether blocked buyers should be able to message you, since leaving that open is why sellers think blocking didn't work.

Then audit what's already there

If you've been selling for a few years, go and read your existing list. Most sellers find at least a handful of names they can't account for, added during some forgotten bad week.

Every one of those is a buyer removed from your market permanently for reasons nobody remembers — and on a category where a repeat customer is worth $150 to $200 in gross terms, a list of twenty unexplained names is potentially $3,000 to $4,000 of lifetime value you've written off by accident.

Clearing the ones you can't justify takes a couple of minutes.

From there, keep it boring. Add a name when behaviour repeats, note why in the same spreadsheet where you track orders, and let the automatic rules handle everything else. A blocked bidder list eBay sellers actually maintain — short, annotated, reviewed once a year — does more for an operation than a long one nobody understands.

For sellers listing across several marketplaces, remember that none of this travels. Your protections on eBay mean nothing on Poshmark, Mercari or Depop, so your own records are the only cross-platform memory you have.
