Ebay Block List

What does the eBay block list cost and where is it?

Last updated: August 2026

Bottom line: it's free, it holds up to 5,000 usernames, and it lives in Account Settings under Site Preferences — Buyer Requirements, not in Seller Hub where most people look first. There's no paid tier, no limit on how often you edit it, and changes take effect immediately for new bids and purchases.

The ebay block list is one of two related tools, and mixing them up is why sellers think the feature doesn't work. The list itself blocks specific usernames you enter.

Buyer requirements, sitting right next to it, block whole categories of buyer — accounts with unpaid item strikes, buyers whose registered address is in a country you don't ship to, accounts with policy violations, and buyers who've exceeded a purchase limit you set over a 10-day window. Individual names go in the first; patterns go in the second.

What it does and doesn't stop

A blocked username can't bid, can't buy, and can't make an offer on your listings. What they can still do is message you, and they can still see everything you have for sale.

Blocking is also account-specific rather than person-specific, so a determined problem buyer with a second account gets through — which is why the buyer requirements settings matter more than the name list for most sellers.

Practically, the ebay block list earns its keep on a handful of cases a year rather than daily. A seller moving 300 orders a month might block six or eight accounts annually: two unpaid bidders, a serial returner who claimed not-as-described on a $180 jacket that came back damaged, and a few scam attempts.

That's a tiny share of transactions, but each one avoided saves a case, a refund, and the hour of messaging that comes with it.

Availability is worth one line: the tool is standard on every US selling account, whether you run a $200-a-month side operation or a Top Rated store, and it carries no volume requirement. International sellers see the same settings page with country-specific shipping options.

Nothing here is gated behind a store subscription, which surprises sellers who assume buyer controls are a paid feature on other platforms.

What does one bad transaction actually cost?

Bottom line: a single not-as-described return on a $180 item costs about $71 in unrecoverable money plus the metric damage, which is why the ebay block list pays for itself the first time it prevents a repeat. The tool is free; the events it prevents are not.

That table assumes the item comes back. When it doesn't — an empty box, a swapped item, a claim closed against you — the loss is the full $180 plus shipping, and the account carries a defect that affects search placement for months.

Two of those in a quarter can push a seller out of Top Rated status, and the visibility cost of that is far larger than any single refund.

It's worth pricing the time as well as the money. A contested case runs four to six messages, a photo review, and often a phone call — call it 45 minutes of attention that lands in the middle of a workday.

At the same $30 an hour, that's $22 per event before anything is refunded, and it comes out of the hours you would otherwise spend sourcing or listing. Sellers who handle three or four cases a month are giving up most of a working day to them.

Where the ebay block list changes the math

Blocking doesn't recover the first loss. It prevents the second, third and fourth from the same account, and repeat behavior is common enough that this matters: sellers who track their problem cases usually find a handful of accounts responsible for a disproportionate share of them.

Adding a username after a bad outcome takes about fifteen seconds, and the ebay block list holds 5,000 of them, so there's no reason to ration entries.

The higher-leverage version is the buyer requirements page. Blocking accounts with two or more unpaid item strikes in the last year filters an entire class of non-payers before they ever bid, at zero cost and with no per-account maintenance.

Sellers running auctions on desirable inventory — sneakers, trading cards, tools — report that single setting removing most of their unpaid item cases. Combined with the ebay block list for named repeat offenders, the pair covers nearly all avoidable buyer-side loss. , according to Federal Trade Commission consumer guides

What do experienced sellers check before blocking someone?

Bottom line: about 70% of the accounts sellers want to block are one-time frustrations rather than repeat risks, and blocking those costs you future sales for no protective benefit — the filter worth applying is whether the behavior is likely to recur. Experienced sellers run three checks before adding a name, and skip the list entirely for the rest.

The first check is whether money was actually at risk. A buyer who asked four annoying questions and didn't purchase cost you ten minutes; a buyer who won a $340 auction and never paid cost you a relist, two weeks of exposure, and possibly a lower final price the second time around.

Only the second belongs on the ebay block list. Sellers who block every irritating message end up with a list full of people who might have bought something later, which is a quiet revenue leak nobody measures.

The second is pattern recognition across your own history. Search your case records for the username before deciding — a first not-as-described claim on a $60 item from an account with 400 positive feedback is usually a genuine dispute, while a second claim from the same buyer within a few months is a pattern.

We suggest keeping a simple text file of blocked names with a one-line reason and a date, because six months later nobody remembers why a username is on the list, and an unexplained ebay block list becomes impossible to audit or trim.

The retaliation question

The third check is timing relative to feedback. Blocking a buyer does not remove their ability to leave feedback on a completed transaction, and it does not undo a defect. Sellers sometimes block in the middle of an open case hoping it stops the process; it doesn't, and it can escalate a conversation that was about to settle.

On a $180 dispute, a $30 partial refund that ends the matter is usually cheaper than a defect, and the ebay block list is what prevents the same buyer from testing you again afterward.

There's a scale consideration too. A seller with 40 active listings and 15 sales a month can afford to be liberal about blocking, because the pool of potential buyers dwarfs the handful of names removed.

A seller with a niche $900 inventory category — vintage synthesizers, specific tool brands, collectible glass — is operating in a small community where the same 200 people buy everything, and removing even a few of them measurably shrinks the market.

In those categories, sellers we work with block roughly a third as often and lean on buyer requirements instead, which filter behavior rather than identity.

Worth naming the one case where speed beats deliberation: obvious fraud. An account created days ago, zero feedback, bidding aggressively on your highest-value listing, messaging about shipping to a freight forwarder — that pattern doesn't need a three-check review.

Cancel, block, and move on, because the downside of being wrong is one lost sale and the downside of being right is a $900 chargeback you spend a month contesting. Sellers who have absorbed one of those learn to act on the signature immediately.

The last piece is maintenance. The list holds 5,000 names and most sellers never review it, which is fine until an account changes hands or a buyer with a genuine one-off problem stays blocked for years.

Once a year, open the ebay block list, read your own notes, and remove anyone whose entry reads like a bad day rather than a pattern.

It takes fifteen minutes and it puts a few dozen buyers back in circulation — a small thing, but it's the difference between a defensive tool and an accumulating grudge that costs you sales you'll never see.

Common questions about blocking buyers

Bottom line: blocking is silent, reversible, and capped at 5,000 usernames — the buyer is never notified, and you can remove a name at any time., according to National Retail Federation research

Does the buyer know they've been blocked?

Not directly. There's no notification. A blocked account attempting to bid or buy sees a message saying it can't complete the purchase and should contact the seller, which does tell an attentive buyer something happened. Most never notice, because they simply move on to another listing.

Nothing appears on their account record either — this is a private setting on your side, not a mark against them.

Can a blocked buyer still message me?

Yes. The ebay block list stops transactions, not communication, so a determined buyer can keep sending messages through the platform. If that becomes harassment, the path is reporting the account rather than blocking it, since only eBay can restrict messaging.

Sellers dealing with a persistent case should keep the message thread intact rather than deleting it — it's the evidence any report will be judged on.

How do I add or remove names in bulk?

The settings page accepts a comma-separated list, so you can paste dozens of usernames at once and, just as easily, replace the whole list with an edited version. Sellers migrating from a spreadsheet usually do it in one paste. Keep that spreadsheet as your master copy with dates and reasons, since the ebay block list itself stores nothing but names.

Does blocking remove existing bids or offers?

No. Blocking prevents new activity; it doesn't retract what's already there. An active bid from an account you just blocked stays live, and you'd need to cancel that bid separately before the auction ends.

On a $340 auction with two hours left, that's a two-step job — block, then cancel the bid — and forgetting the second step is a common and expensive mistake.

Is there a limit I should worry about?

The 5,000-name cap is far beyond what any normal seller reaches; a busy shop adds perhaps ten a year. For reference, a shop running 300 orders a month typically has under 30 names on file after five years of selling.

If you're approaching a number that feels large, that's usually a sign your buyer requirements are too loose rather than that you need more room on the ebay block list. Tighten the automatic filters — unpaid strikes, shipping regions, purchase limits — and the manual list stops growing.

Set this up in the next ten minutes

Bottom line: two settings pages, ten minutes, zero cost — and they remove most of the buyer-side risk that turns into $71 losses and account defects. Do the automatic filters first, because they work while you sleep; the manual list is for the exceptions that get through.

Open Account Settings, go to Site Preferences, and find Buyer Requirements. Turn on the block for buyers with two or more unpaid item strikes in the last twelve months, restrict buyers whose primary shipping address sits in countries you don't ship to, and set a purchase limit if you sell high-demand inventory in small quantities.

Then open the ebay block list itself and paste in any usernames you've been keeping in your head or in a notes app. Save both pages. That's the whole setup, and it's the same ten minutes whether you sell 15 items a month or 500.

Build the habit that keeps it useful

After each unresolved case, add the username with a date and a one-line reason to a spreadsheet, then paste the updated list in. Once a year, read the reasons and remove anything that reads like a single bad day.

Sellers who keep those notes end up with a list of maybe 30 genuine repeat risks after five years; sellers who don't end up with 200 names, no context, and a shrinking buyer pool they can't audit.

For the adjacent problems — unpaid items, return abuse, feedback disputes and the metrics that hang on them — the Closo blog hub has deeper guides, including how defect rates affect search placement and what a partial refund is actually worth compared to a case.

If you're running multiple channels, the crosslisting material covers the cancellation risk that no ebay block list can help with, since that one comes from your own inventory sync rather than from buyers.
