Direct answer: On Poshmark, counterfeit listings are reported through the listing's menu using the copyright and counterfeit options, and a fake you received is disputed by opening a case in the order before accepting it. Poshmark's review team decides cases from photos and receipts, so side by side evidence, clear shots of labels and hardware, and proof of purchase decide outcomes more than descriptions do.
Poshmark's closet model means millions of individual sellers and no warehouse checkpoint between a fake and a buyer. The platform leans on reports and its order case system to catch counterfeits after the fact, which puts the quality of your report at the center of the outcome.
This guide covers both directions: reporting a counterfeit listing you spot while shopping, and disputing an item you bought that turned out to be fake, including what evidence Poshmark reviewers respond to.
Open the listing, tap the menu, and use the report flow, choosing the counterfeit or copyright violation category where offered. Be specific in the notes field: name the exact tells visible in the listing photos, a misspelled brand stamp, the wrong hardware shape, a serial format the brand never used. Vague fake reports are easy to queue behind specific ones.
Understand the limit of the tool: Poshmark may remove the listing, warn the seller, or take no visible action if the photos do not prove the case. Luxury items above the platform's authentication threshold get a physical check when sold, but the vast majority of listings sell on trust plus reports, which is why precise reports carry weight.
Do not accept the order. Accepting releases payment and largely ends your leverage. Instead, open a case from the order within the review window, state that the item is counterfeit and not as described, and write it as a factual comparison: what was advertised, what arrived, and the specific differences.
Poshmark assigns a reviewer who was not in the chat and reads the case cold. Write for that person. Number your points, keep emotion out, and attach the strongest comparison evidence first. Sellers who respond calmly with authentication proof of their own sometimes win; assume they will try, and make your evidence stronger than a confident tone.
Side by side photographs carry cases: the received item next to reference images of the authentic product from the brand's own site, with differences circled or described per photo. Close ups of labels, date codes, stitching, hardware weight and finish, and packaging details give the reviewer checkable facts.
Proof of inauthenticity from a third party authentication service, even a basic paid opinion, changes the posture of a case. So does the seller's own listing text: if they wrote one hundred percent authentic and guaranteed, quote it. What does not move reviewers is price alone; cheap is suspicious, not proof, and cases built only on the deal being good tend to fail.
Sellers get reported too, sometimes by competitors, sometimes by buyers pattern matching wrong. Keep receipts, order confirmations, and boutique tags for anything branded you list, photograph labels and codes at listing time, and answer authenticity questions in comments with facts rather than offense.
If a listing of yours is removed, the appeal goes better with documents than with indignation: upload the purchase proof, explain your sourcing, and keep the tone boring. Accounts with a history of clean documentation survive false reports that sink undocumented sellers, because the platform can only defend what it can verify.

You have three days from delivery to inspect the item and either accept it or open a case before payment releases automatically. Do not let the window close while you research authenticity; open the case with what you have, since you can add comments and photos while it is under review.
Only items at or above its set price threshold for the authentication service, which are routed through Poshmark's team before reaching the buyer. Everything below that ships directly from seller to buyer with no physical check, which is exactly why listing reports and order cases do the heavy lifting on most of the platform.
Outcomes range from listing removal and warnings to return funded refunds and account suspension, depending on the evidence and the seller's history. Repeat or high volume counterfeit selling risks permanent removal. Buyers in a proven case get refunded through the platform, including in most cases the return shipping arrangement the reviewer sets.
Yes, the listing report flow exists for exactly that. Include specific visible tells rather than a bare accusation, since reviewers act on what the photos show. Reports from shoppers genuinely protect other buyers, but they rarely produce a notification back to you about the outcome.
Read the denial reason, then respond inside the case if it remains open with the evidence that addresses it, usually clearer comparison photos or third party authentication. If the case closes against you, your remaining routes are the payment provider's dispute process, which will ask what the platform decided and why, so keep the case record.
